If the external monitor is turned off when you boot the computer, and if the Video Display Device category is set to CRT Mode in the Main menu of the Setup program, the computer sends the video image to the external monitor. In this case, you do not see an image on either the computer's display or on the external monitor. To resolve this situation, turn on the external monitor or press <Fn><F8> to switch the video image to the computer's display.

Whether you are using an appropriately equipped multifrequency monitor only or you are using an external monitor and the built-in display simultaneously, you can display up to 16 million colors at a noninterlaced resolution of 1280 x 1024 pixels.

CAUTION: Do not place the monitor directly on top of your portable computer, even if it is closed. Doing so can crack the computer case, the display, or both.

NOTE: When the external monitor and built-in display are used simultaneously, the refresh rate is always 60 Hz. Each time you press <Fn><F8>, the computer switches the video image to the next display in the following sequence: the built-in display, an external monitor, both displays simultaneously.

video card

An expansion card that provides the video capabilities—in combination with the monitor—for your computer system. A video card may support more or fewer features than a specific monitor offers. Typically, a video card comes with video drivers for displaying popular application programs and operating systems in a variety of video modes.

Video cards can include memory separate from RAM on the system board. The amount of video memory, along with the card's video drivers, may affect the number of colors that can be simultaneously displayed. Video cards can also include their own coprocessor for faster graphics rendering.

video driver

A program that allows graphics-mode application programs and operating systems to be displayed at a chosen resolution with the desired number of colors. A software package may include some "generic" video drivers. Any additional video drivers may need to match the video card installed in the computer.

video memory

Most VGA and SVGA video cards include memory chips in addition to the computer's RAM. The amount of video memory installed primarily influences the number of colors that a program can display (with the appropriate video drivers and monitor capabilities).

video mode

Video cards normally support multiple text and graphics display modes. Character-based software, such as text editors, display in text modes that can be defined as x columns by y rows of characters. Graphics-based software, such as the Windows 98 operating system, displays in graphics modes that can be defined as x horizontal pixels by y vertical pixels by z colors.

video resolution

Video resolution—800 x 600, for example—is expressed as the number of pixels across by the number of pixels up and down. To display a program at a specific graphics resolution, you must install the appropriate video drivers and your monitor must support the resolution.

virus

A program designed to be an inconvenience, either by replicating itself until a computer or network runs out of memory or by corrupting files stored on a hard-disk drive.

The most common way that virus programs move from one computer to another is via "infected" diskettes and from software downloaded from the Internet. When an infected program is started, so is the embedded virus.

W

Abbreviation for watt(s).

wallpaper

The background appearance of the Windows desktop.

WH

Abbreviation for watt-hour(s).

win.ini file

A start-up file for the Windows operating system. When you start Windows, it consults the win.ini file to determine a variety of options for the Windows operating environment. Among other things, the win.ini file records what printer(s) and fonts are installed for Windows. The win.ini file also usually includes sections that contain optional settings for Windows application programs that are installed on the hard-disk drive.

Windows 98

An integrated and complete Microsoft Windows operating system that does not require MS-DOS and provides advanced operating system performance, improved ease of use, enhanced workgroup functionality, and simplified file management and browsing.

Windows NT

High-performance server and workstation operating system software intended for technical, engineering, and financial applications.

write-protected

Read-only files are said to be write-protected. You can write-protect a 3.5-inch diskette by sliding its write-protect tab to the open position or by

Page 55

setting the write-protect feature in the system setup program.

XGA

Abbreviation for extended graphics array. VGA, SVGA, and XGA are video standards for video adapters with greater resolution and color display capabilities than previous standards. XGA generally refers to a video resolution of 1024 x 768 pixels.

To display a program at a specific resolution, you must install the appropriate video drivers and your display and/or external monitor must support the resolution. Similarly, the number of colors that a program can display depends on the capabilities of the display and/or monitor, the video driver, and the amount of video memory installed in the computer.

XMM

Abbreviation for extended memory manager, a utility that allows applications and operating systems to use extended memory in accordance with the XMS.

XMS

Abbreviation for eXtended Memory Specification.

ZV Port

Abbreviation for Zoom Video port. A port to the video controller that provides hardware MPEG-1 decode (and encode) solutions in notebooks. These solutions could include PC Card (CardBus), or on-board solutions. ZV Port must be integrated into notebook board design to allow for these solutions to be passed directly through to the video processor, circumventing the processor, allowing for more efficient CPU utilization.

Windows NT does not support Zoom Video.

I/O Connectors

Infrared Port

The computer comes with an infrared port. An infrared data stream is transmitted through a lens in the computer, up to a distance of 1 m, and received by a compatible computer, printer, mouse, or remote control.

The infrared port lets you transfer files from the computer to another infrared device, without using cable connections. You can also use other commercially available infrared-capable application programs.

To use the infrared port, point the computer’s infrared port directly at the infrared port of the compatible device. Infrared devices transmit data in a 30°coneofinfrared

light. Start the data communications software on both devices, and then begin transferring files. Read the documentation that came with your compatible device to make

sure you operate it correctly.

For information on configuring the standard infrared drivers that came with Windows 98, see your operating system documentation.

USB Connector

Use the USB connector to attach up to two USB devices, such as a mouse, to the computer. USB is a peripheral bus standard that enables automatic detection of USB-compliant peripheral devices.

Pin Assignments for the USB Connector

Serial Connector

Use the 9-pin serial connector to attach a serial device to the computer. The serial port passes data in serial format (one bit at a time over one line). This port supports a variety of devices, including a serial mouse, that require serial data transmission. If you reconfigure your hardware, you may need pin number and signal information for the serial connector.

Pin Assignments for the Serial Connector

NOTE: Make sure that there are no books, papers, or other objects between the two infrared devices and that the two devices are within the 30° cone.

Passwords and Security: Dell™ Inspiron™ 3500 Portable Computer

About Passwords | Physically Securing the Computer | Disabling the Serial, Infrared, and Parallel Ports

About Passwords

When you receive the computer, the password features are disabled so that you can assign passwords if you wish. Once you assign a password, you must enter the password to access the Setup program.

Use the Security menu in the Setup program to assign a password.

Physically Securing the Computer

To prevent unauthorized removal of the computer, use a security cable to attach the computer to an immovable object.

The security cable slot lets you attach a commercially available antitheft device to the computer. Antitheft devices for portable computers usually include a segment of metal-stranded cable with an attached locking device and associated key. Complete instructions for installing this kind of antitheft device are usually included with the device.

To prevent unauthorized removal of the computer, loop the cable around an immovable object, insert the locking device into the security cable slot, and lock the device.

Disabling the Serial, Infrared, and Parallel Ports

You can disable the serial port to prevent unauthorized access to the computer through an external serial device. To disable the serial port, set the Serial Port option to Off in the System Devices menu of the Setup program. In addition, you should set up a password in the Security menu of the Setup program.

You can disable the infrared port to prevent unauthorized access to the computer through an external infrared device. To disable the infrared port, set the IR Port option to Off in the System Devices menu of the Setup program.

You can disable the parallel port to prevent unauthorized access to the computer through an external parallel device. To disable the parallel port, set the Parallel Port option to Off in the System Devices menu of the Setup program.

Disabling any of these ports also prevents the unauthorized download of data from that port.



CAUTION: The password features provide a high level of security for the data in the computer. However, they are not foolproof. If your data requires more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption programs or PC Cards with encryption features.

NOTE: Antitheft devices are of differing designs. Before purchasing such a device, make sure it will work with the security cable slot in the computer.

PC Cards: Dell™ Inspiron™ 3500 Portable Computer

About PC Cards | Installing PC Cards | Removing PC Cards | Configuring PC Cards

About PC Cards

You can install up to two PC Cards that adhere to PCMCIA standards and release 4.2 of the JEIDA standard.

The computer supports type I, type II, and type III PC Cards, including such memory devices as SRAM cards that emulate diskettes, RAM cards, OTP ROM cards, and ATA cards that emulate IDE hard-disk drives. The computer also can support I/O cards such as modem communication cards, LAN cards, wireless LAN cards, SCSI cards, and sound cards.

You can install one type III or two type I or type II cards in the computer. You can also use extended PC Cards in the computer.

Both PC Card slots support CardBus technology. In addition, a ZV Port is available from the lower slot (slot 0). If you ordered an MPEG -2 decoder PC Card from Dell, install it in the lower PC slot.

Installing PC Cards

The PC Card slot has two PC Card connectors and supports four combinations of cards:

l A single type I or type II card (using either the top or bottom PC Card connector) l One type I card and one type II card (using either connector) l Two type I cards or two type II cards l One type III card (using the bottom connector)

The type of card refers to its thickness, not its functionality. Because a type III card is thicker than type I and type II cards, it takes up the entire PC Card slot, although it uses only one PC Card connector.

PC Cards are generally marked with a symbol (such as a triangle or an arrow) to indicate which end should be inserted into the slot. The cards are keyed to prevent incorrect insertion. If card orientation is not clear, see the documentation that came with the card.

You can install a PC Card while the computer is running. The PC Card is automatically detected.

Unpack the card and install it by performing the following steps:

1. If necessary, remove the blank from the connector you intend to use.

2. Hold the card with its orientation symbol pointing into the slot and the top side of the card facing up.

3. Insert the card into the slot and press in firmly until the card is completely seated in the internal PC Card connector.

If there is too much resistance when inserting the card, do not force the card. Check the card's orientation, and try again.

The computer recognizes most I/O cards and automatically loads the appropriate device driver.

If you have older modem communications software that cannot use certain IRQ settings, you must disable the serial port or infrared port to use the software.

Removing PC Cards

To remove a PC Card, use your finger tip to flip the eject button out so that it is perpendicular to the computer. Push in the eject button to release the card. Gently

CAUTION: Take extra precautions if you use extended PC Cards in the computer. Extended cards are longer versions of standard PC Cards. They fit into, and operate correctly with, the computer. However, they extend beyond the edge of the computer when installed. If something

strikes the exposed end of an installed card, the card or the system board can be damaged. Always remove an extended PC Card before you pack

the computer for traveling.

NOTE: Because of space considerations, you may have trouble using two PC Cards in the computer if one of them is an extended card. Always install an extended card in the top PC Card connector.

NOTES: A PC Card is not a boot device.

"Type of card" refers to its thickness, not its functionality.

NOTE: It is important that you complete the setup of your operating system before installing a PC Card.

NOTES: If you ejected a blank or another PC Card before you inserted the PC Card, the eject button slides out when you insert the new card. To

Power Sources: Dell™ Inspiron™ 3500 Portable Computer

AC Adapter

The AC adapter converts AC power to the DC power required by the computer. The AC adapter kit includes two cables: the AC adapter cable and an AC power cable.

You can connect the AC adapter with your computer either turned on or off.

The AC adapter works with AC power sources worldwide. However, power connectors vary among countries. Before using AC power in a foreign country, you may need to obtain a new power cable designed for use in that country.

If you are running your computer on AC power with a battery installed, the AC adapter charges the battery (if needed) and then maintains its charge.

When your computer is turned on, the green power indicator light is constantly lit, which indicates that the system is active. This light is on when the computer is running either from AC or battery power. If the light is amber-colored, the computer is in Standby mode.

The battery charge indicator LED shows the status of the battery. When the AC adapter is connected to the computer, this light is green. When the battery is charging, this light blinks slowly. When this light stops blinking and becomes solid green, the battery is fully charged.

Battery

The battery uses lithium ion technology to power the computer when it is not connected to an AC power source. The main battery comes standard with the computer. To double battery life, you can install an optional second battery in the options bay.

You can expect 2 to 3 hours of battery life with a single fully charged battery and 4 to 6 hours of battery life with two fully charged batteries. A built-in charge gauge lets you check a battery's charge before you insert it into the computer. The battery's self-test capability alerts you to battery conditions such as low charge.

A number of factors affect battery operating time:

l The power conservation features used l The number and type of PC Cards used l The kinds of application programs run l The capacity of the optional memory module installed (the higher the capacity, the more power used) l The use of an internal Zip drive, CD-ROM drive, or DVD-ROM drive, which use more power than a hard-disk drive or a diskette drive

See also Power Conservation.

Removing and Installing the Main Battery

To remove and install the main battery, perform the following steps:

1. Save any files you have open and exit all application programs.

2. If your computer is operating on battery power, preserve your data by connecting the AC adapter and plugging it into an electrical outlet or by shutting down yourcomputerfromtheStartmenu.

3. Remove the main battery.

Using your index finger, pull the battery bay latch (located on the side of the computer next to the battery bay) toward you. With your thumb, gently push the latch out and back until the battery pops out. Grasp the battery firmly and slide it out of the battery bay.

4. Install the new battery.

With the battery bay latch released, slide the new battery into the battery bay until it is flush with the computer casing. You cannot fully insert the battery into the computer unless the battery bay latch is released.

Removing and Installing a Second Battery

To remove and install the second battery, perform the following steps:

1. Save any files you have open and exit all application programs.

3. Remove the main battery.

Using your index finger, pull the options bay latch (located on the side of the computer next to the options bay) toward you. With your thumb, gently push the latch out and back until the battery pops out. Grasp the battery firmly and slide it out of the options bay.

4. Install the new battery.

With the options bay latch released, slide the new battery into the options bay until it is flush with the computer casing. You cannot fully insert the battery into the computer unless the options bay latch is released. Close the options bay latch by using your index finger to push it toward the front of the computer until it is flush with the computer casing. Using

your thumb, push the options bay latch in.

5. Turn on the computer.

Charging the Battery

Each time you connect the computer to AC power or install a battery in a computer that is connected to AC power, the computer checks the battery's charge and temperature. The AC adapter then charges the battery (if necessary) and maintains the battery's charge.

If two batteries are installed in the computer, the AC adapter charges the battery in the battery bay first, and then charges the second battery in the options bay. (The second battery is discharged first.)

The battery LED, located to the right of the display latch, appears as a blinking green light while the battery is charging.

The AC adapter needs from 2 to 3 hours (depending on whether the system is on or off) to fully charge a battery that has been completely discharged.

Checking a Battery's Charge Level

Use one of the following methods to check the battery's charge level:

l Check the battery charge level before you insert the battery into your computer. Once the battery is inserted into the computer, you cannot see the charge gauge.

The battery has a charge gauge with five charge-level indicator lights that show how much battery charge remains. Press the battery tester (a textured square on the back of the battery) to check the charge level. Each light represents approximately 20% of the total battery charge. For example, if the battery has 80% of its charge remaining, four of the lights come on during testing. If none of the lights come on when you press the battery tester, the battery has no charge left.

l A low-battery warning occurs when the battery is about 90% depleted. The speaker beeps once every 15 seconds. When you hear the low-battery warning,

only a few minutes of battery life remain. If both the main battery and the second battery are installed, the low-battery warning means that the combined charge of both batteries is about 90 percent depleted.

l If you are using the Microsoft

Windows® 98 operating system, click the Start button, point to Settings, and then click Control Panel. Double-click the

Power Management icon to open the Power Management Properties window. For more information, check the documentation that came with your

operating system.

l The Windows 98 battery meter displays a battery icon that shows the amount of battery charge remaining. If an AC adapter is connected to the computer, the

battery meter displays a plug icon. The battery meter icons are visible in the desktop taskbar. If you move the cursor over the battery or plug icon in the desktop taskbar, a pop-up window shows the battery's current charge status percentage.

NOTE: You can leave the battery in the computer as long as you like. The battery's built-in circuitry prevents the battery from overcharging.

CAUTION: If only one or none of the charge-level indicator lights are lit, it indicates a critically low battery state. Do not use the battery unless the computer is connected to AC power or unless you install a second charged battery.

CAUTION: To avoid losing data (and possibly corrupting data areas on your hard-disk drive), save your work immediately after a low-battery warning. Then connect the computer to AC power, or install a second battery in the options bay. If the battery runs completely out of power, the computer activates save-to-disk suspend mode.

Power Management: Dell™ Inspiron™ 3500 Portable Computer

How to Conserve Battery Power

You automatically conserve battery power each time you attach an AC power source to the computer. When the AC adapter is attached, the battery or batteries, if installed, are being charged while the computer runs from AC power. The life expectancy of your battery is determined largely by the number of charges it receives, so use an AC power source to run the computer if one is available.

Use the Windows 98 Power Management Properties window to adjust the way the computer uses battery power. Options in the window slow or stop some internal devices when the computer is idle.

Take advantage of the computer's power management modes, set in the Windows 98 Power Management Properties window, when you leave the computer unattended for long periods of time. Standby, Turn Off Monitor, and Turn Off Hard Drive allow you to maximize power conservation when your work is interrupted.

When the computer is using battery power, remove PC Cards that you are not using.

Experiment with power conservation features to achieve the optimum power conservation for your work environment.

Using Microsoft® Windows® 98 to Conserve Battery Power

Complete the following steps in Windows 98 to access the Power Management Properties window and set the power management features:

1. Click the Start button, point to Settings, and click Control Panel.

2. Double-click the Power Management Properties icon.

The Power Management Properties window contains the following tabs:

l Power Schemes allows you to select one of three power mode settings. l Alarms allows you to set the Low battery and Critical battery alarms to alert you when the system battery falls below a certain percentage. When you received your

computer, the Low battery and Critical battery alarms check boxes were not checked. Dell recommends that you do not select these options.

l Power Meter allows you to view the percentage of battery life remaining when your system is operating on battery power. If your system is operating on AC power,

the system displays a message.

l Advanced allows you to display the Power Meter on the Windows 98 taskbar and to display a password prompt when the computer resumes from Standby mode.

3. Select the appropriate settings for the power management features you want.

Experimenting with Power Conservation

In general, the lower the value you set for each time-out option, the longer your battery's charge lasts. On the other hand, setting high time-out values tends to optimize the computer's performance. For best results, experiment with the following conservation methods:

l Use the computer with all the options set to their defaults. l Use the computer with all the time-out options disabled or set to Off. l Use the computer with all the time-out options set to their minimum values.

Evaluate the way that the different time-out settings affect how long you can operate the computer on battery power versus the relative efficiency of how your software performs.

Checking the Battery Status

The battery status LED on the front of the computer's display indicates the battery's current operating status. The LED has three states:

l Flashing green, which indicates that the AC adapter is connected and the battery is charging. l Solid green, which indicates that the AC adapter is connected and the battery is fully charged. l No light, which indicates that the AC adapter is not connected.

NOTE: You can also set power management modes in the Setup program's Power menu. However, the Windows 98 power management settings always override the power management selections chosen in the Setup program.

NOTE: You might have to trade some of the computer's performance for increased battery operating time. For example, if you turn off the hard-disk drive, you may experience a delay the next time the computer tries to access the drive.

Page 79

Standby Mode

Standby turns off the display, stops the hard-disk drive, and turns off other internal devices so that the computer uses less battery power. When the computer resumes

operation from Standby mode, the desktop is restored exactly as it was before entering Standby mode.

You can activate Standby mode by pressing <Fn><Esc> or by selecting Standby from the Shutdown window. To resume operation from Standby mode, press the power button.

Turn Off Monitor

The Turn Off Monitor option turns off the display so that the computer uses less battery power. You can press any key or the touch pad to turn on the display. The desktop is restored exactly as it appeared before the display was turned off.

Turn Off Hard-Disk Drive

The Turn Off Hard-Disk Drive option turns off the hard-disk drive so that the computer uses less battery power. You can press any key or the touch pad to turn on the hard-disk drive. The desktop is restored exactly as it appeared before the hard-disk was turned off.

Save-to-Disk Suspend Mode

Save-to-disk suspend mode copies all system data to a reserved area on the hard-disk drive and then turns off all power to the computer. When you resume normal operation, the same programs will be running and the same files will be open that were open before you activated this mode.

To activate save-to-disk suspend mode immediately, press <Fn><A> (or <Fn><Q> on the French keyboard).

To resume using the computer after activating save-to-disk suspend mode, press the power button. It may take up to 2 minutes for the computer to return to its previous state.

Some PC Cards may not operate correctly after exiting from save-to-disk suspend mode. If you encounter problems with a card, remove and replace it.

Save-to-Disk Suspend File

The save-to-disk suspend file on your hard-disk drive cannot be accessed by the operating system or application programs. When save-to-disk suspend mode is activated, all system data is stored in this file.

Use the following instructions to create a save-to-disk suspend file if you installed a new hard-disk drive, if you removed the file, or if you are rebuilding a corrupted hard-disk drive. If possible, print these instructions before you begin this procedure.

1. Save and exit any application programs and files that you have open and shut down the computer.

2. Insert the Microsoft Boot Disk Windows 98 Series diskette into the diskette drive.

3. When the Microsoft Windows 98 Startup Menu appears, use the down-arrow key to select Start computer with CD-ROM support and press <Enter>.

4. When A:\> appears on the screen, insert the Dell Inspiron 3500 System Software CD into your CD-ROM or DVD-ROM drive.

Your MS-DOS prompt changes from an A:\ to a D:\, assuming that d is the drive letter of your CD-ROM or DVD-ROM drive.

5. Type cd\utilities and press <Enter>.

6. Type phdisk /create /file and press <Enter>.

CAUTION: Windows 98 saves data to RAM, not to your hard-disk drive, before entering Standby mode. If the computer enters Standby mode while running on battery power, data loss from RAM can occur if the battery discharges completely.

NOTES: Save-to-disk suspend mode helps preserve system data by quickly saving it onto the hard-disk drive if you are about to run out of battery power.

Place the computer in save-to-disk suspend mode if you do not intend to store the computer for longer than 40 days. Save-to-disk suspend mode preserves the configuration information stored in NVRAM. The reserve battery maintains this information, but may run out of energy after 40 days.

NOTE: Save-to-disk suspend mode requires a special file on your hard-disk drive that sets aside enough disk space to store the contents of the computer's memory. Dell creates an appropriately sized save-to-disk suspend file before shipping the computer to you. If you remove the file or add memory to the computer, or if your hard-disk drive becomes corrupted, you must re-create the file before you can again use save-to-disk suspend mode.

NOTE: If you installed additional memory, delete the save-to-disk suspend file and then complete this procedure. To delete the save-to-disk suspend file, type the following at an MS-DOS prompt and press <Enter>:

PHDISK /DELETE /FILE

Page 80

The utility calculates the size of the file, in kilobytes, based on the amount of system memory in your computer, plus 2 MB to handle video memory and additional system requirements.

7. Follow the instructions on your screen to create the save-to-disk suspend file.

To check the size of the save-to-disk suspend file, type phdisk /info at an MS-DOS prompt and press <Enter>. If you need to delete the save-to-disk suspend file, type phdisk /delete /file at an MS-DOS prompt and press <Enter>.



NOTE: Make sure that there is a space between phdisk /create and /file.

Procedures for Field- and Depot-Replaceable Parts

NOTICE: During the removal and replacement procedures, you will see Kapton tape in many places on the computer. When reinstalling or replacing parts, be sure to replace the Kapton tape correctly to retain the electrical protection and noise reduction the tape provides.

Unless otherwise noted, each procedure assumes the following:

l You have the recommended tools. l You have performed the steps in Precautionary Measures. l The computer and any attached peripherals are turned off and the peripherals are disconnected from the computer's I/O panel. l You can replace or reinstall a part by performing the removal procedure in reverse order unless additional information is provided.

Procedures for field- and depot-replaceable parts are described in these sections:

l 13.3- and 14.1-Inch Display Assemblies l Palmrest Assembly l Drive Assemblies l Base Assembly

Recommended Tools

Most of the procedures require the use of one or more of the following tools:

l Small flat-blade screwdriver l Number 1 Phillips-head screwdriver l Antistatic grounding strap l Dental pick or similar pointed instrument l Small scribe or nylon flat blade l Nut drivers (5 mm and 5.5 mm)

Screw Identification and Tightening

NOTICE: The correct-length screw must be used when reinstalling a screw. Otherwise, hardware damage could result. Make sure that the screw is properly aligned with its corresponding hole, and avoid overtightening.

Where applicable, information about screw lengths is provided with the illustrations. The Inspiron 3500 portable computer contains many screws of various sizes. Be careful not to scratch the computer plastic case by allowing

screws to get between the disassembly surface and the plastic case. Dell suggests a soft, padded work surface. While removing and replacing parts, use a tackle or pill box as a storage device to keep track of the screws. Use the following location template to

store the screws during disassembly.

NOTES: If the computer is booted with a diskette drive or second battery in the media bay, you must reboot after installing another device in the media bay.

To remove the media from the CD-ROM drive, DVD-ROM drive, or Zip drive once the power to the drive is off, insert a small, thin object (such as one end of a paper clip) into the pinhole near or in the device’s LED. This ejects the media or the media tray so you can retrieve the CD, DVD, or Zip disk.

CAUTION: Only a certified service technician should perform these procedures for removal, replacement, and installation of parts. The warranty on the computer becomes void if anyone other than a certified technician performs these procedures.

NOTE: Each removal and replacement procedure lists the type, size, and torque value of screws removed during the procedure. Screw types include flat head (FLH), flat pan-head (FPH), pan head (PNH), and jack screws.
