System Setup

Setting up your system

Follow the instructions on the poster that came with your system for assembly instructions. You can prepare a safer working environment before assembling your system by following the guidelines listed below.

■ Provide a clean, flat, stable surface for your system. Allow at least

12 inches at the back of the computer for cabling and air circulation.

■ Obtain a grounded (three-prong) AC surge-protected power strip. A

surge-protected power strip helps protect against AC line spikes.

■ Protect your system from extreme temperature and humidity. Do not

expose your system to direct sunlight, heater ducts, or other heat-generating objects.

■ Keep your computer away from equipment that generates magnetic

fields, such as unshielded stereo speakers. Even a telephone placed too close to the computer may cause interference.

■ Plug the computer into a wall outlet or power strip that is easily

accessible. When you turn off the computer with the power button, some electricity still flows through the computer. To remove all power from the computer, you need to unplug it.

Important Keepthe productcarton and packing material, in caseyou

need to send the system out for repair. If you return your system to the factory in different packaging, your warranty may be void.

Settingupyoursystem 13

Starting your system

Before you start your system for the first time:

■ Refer to the safety information beginning on page 101.

■ Make sure the voltage selector switch on the back of the computer is set

to the correct voltage for your area. This switch is set at the factory to the correct voltage (see “Back panel” on page 5 for voltage selector switch location).

■ Make sure all cables are firmly connected to the proper ports on the back

panel of the computer.

Caution Make sure your computer and peripherals are turned off

and unplugged from the power outlet when you connect peripherals to the computer.

■ Make sure the computer and monitor are plugged into an AC outlet or

power strip.

To start the system:

1 If you have connected the system components to a power strip, make

sure all the system components are turned off, then turn on the power strip.

Case Access

Static electricity precautions

Static electricity can permanently damage electronic components in your computer. When opening your computer case, always perform the following procedure.

Caution Prevent electrostatic damage to your computer by

following static electricity precautions every time you open your computer case.

To avoid static electricity discharge:

1 Wear a grounding wrist strap (available at most electronics stores). 2 Turn off the computer power. 3 Discharge any static electricity by touching a bare metal surface on the

back of the case.

4 Unplug all power cords from AC outlets and disconnect the modem cable

(if installed).

Static electricity precautions 17

Follow these precautions to avoid electrostatic damage to your system components:

■ Avoid static-causing surfaces such as plastic and packing foam in your

work area.

■ Remove the parts from their antistatic bags only when you are ready to

use them. Do not lay parts on the outside of antistatic bags since only the inside of the bags provides antistatic protection.

■ Always hold cards by their edges and their metal mounting brackets.

Avoid touching components on the cards and the edge connectors that connect to expansion slots.

■ Never slide cards or other parts over any surface.

Warning Avoid exposure to dangerous electrical voltages and

moving parts by turning off your computer. Unplug the power cord and modem cord before r emoving the computer cover.

Managing Your System

Protectingagainst power source problems

Surge suppressors, line conditioners, and uninterruptible power supplies (UPS) can help protect your system against power source problems.

Surge suppressors

During a power surge, the voltage level of electricity coming into your system can increase far above normal for a few milliseconds. This may cause data to be lost or the system may be damaged as a result. To protect against power surges, use a surge suppressor. The surge suppressor absorbs voltage surges and prevents them from reaching your system.

A surge suppressor plugs directly into an electrical outlet. You should connect your computer, monitor, and other devices to the surge suppressor.

If you have a modem, make sure your surge suppressor has jacks for the telephone and modem cables. Power surges can pass through telephone wires as well as electrical wires.

Protecting against power source problems 69

When purchasing a surge suppressor:

■ Make sure the surge suppressor meets the appropriate product safety

certification for your location, such as Underwriters Laboratories (UL).

■ Check the maximum amount of voltage the suppressor allows to pass

through the line. The lower the voltage that the suppressor allows to pass through, the better the protection for your system.

■ Check the energy absorption, or dissipation, rating. The higher the energy

absorption rating, the better the protection for your system.

■ Check for line-conditioner capabilities. A line conditioner smooths out

some of the normal line noise (small voltage fluctuations) of an electrical supply.

Line conditioners

A line conditioner protects your system from the small daily fluctuations in voltage from an electrical supply. Most systems can handle this variation, or line noise, without problems. However, some electrical sources include more line noise than normal. Line noise can also be a problem if your system is located near, or shares a circuit with, a device that causes electromagnetic interference, such as a television or a motor.

Some surge suppressors and uninterruptible power supplies include simple line-conditioning capabilities.

Uninterruptiblepower supplies

You may lose data during a total power failure. A standby Uninterruptible Power Supply (UPS) uses a battery to keep your system running during a power failure. The UPS enables you to shut down your system normally, but not run the system for an extended time.

If you purchase a standby UPS, make sure the UPS includes surge suppression and line-conditioning features.

70 Managing Your System

Maintaining and managing your hard drive

Regular maintenance can keep your hard drive operating efficiently, and good file management can keep your system free of unwanted files while making important files secure and easier to find.

Harddrive maintenance utilities

By regularly using the utilities available with many operating systems, you can help maintain the performance of your hard drive. Examples include:

■ ScanDisk

■ Check Disk

■ Disk Defragmenter

Refer to the software documentation or visit the online help system of your operating system for specific utilities available and instructions on their use.

Checking for bad sectors and other disk problems

Bad sectors are parts of a hard drive or diskette that will not hold data. A lost allocation unit is a group of sectors that has lost its place in the table that the operating system uses to locate files. Utilities such as ScanDisk and Check Disk check the hard drive for bad sectors or lost allocation units and let you fix them.

Use this type of utility from once a week to once a month, depending on how often you use your system. Also use them if you have any hard drive problems.

Using adisk defragmenter to improve efficiency

When working with files, Windows may divide the files into pieces and store the pieces at different places on the hard drive. This division of files, called fragmentation, is normal. However, to access a file, the hard drive must search for the pieces of the file and put the file back together, which can slow down your system.

A disk defragmenter brings all the separate pieces back together. Defragment your computer frequently to improve system performance.

Maintaining and managing your hard drive 71

Hard drive management practices

By deleting unneeded files from your hard drive and managing the space that is automatically allocated for saving certain files, you can help maintain the performance of the hard drive.

Checkingharddrive space

In Windows, you can see a chart of the available hard drive space.

To check hard drive space:

1 Double-click the My Computer icon on the desktop. The My Computer

window opens.

2 Click the drive you want to check. 3 Select File, then Properties. The drive’s properties window opens. The

General tab shows you the available and used space on the drive.

Backingupfiles

Regularly backing up your files protects you from losing data and lets you keep fewer files on your hard drive. Back up old files to a network drive or tape drive and delete the files from your hard drive. You can use the software that came with your tape backup drive or your large capacity disk drive to back up the files.

You can also back up files by running the backup utility that came with your operating system. Refer to the software documentation or visit the online help system of your operating system for specific instructions on backing up your files.

Deletingunneeded files

By deleting unneeded files from the hard drive, you free up space on the hard drive and help improve hard-drive performance. The following sections give you some simple ways to delete unneeded files.

Deleting Windows temporary files

During normal operation, Windows constantly creates new temporary (.tmp) files. You can safely delete all but the most recent temp files. Windows will not delete a .tmp file if the file is currently in use.

72 Managing Your System

To delete .tmp files:

1 Open Explorer, select Tools, then Find, then Files and Folders. 2 At Named, type *.tmp 3 In the Look in drop-down list, select your drive letter. 4 Click Find Now. The list of .tmp files is generated. 5 Click Modified above the list. To see the Modified button, you may need

to maximize the Find window.

The list is sorted by date.

6 Highlight all the files in the list except those with today’s date. 7 Press DELETE.

Deleting temporary Internet files

As you visit Web sites, your browser stores temporary Internet files on your hard drive in a memory cache and a disk cache. Files in the memory cache are removed when you turn off your computer. Files are saved in the disk cache until the space designated for the cache is full. See your browser’s Help files for instructions on emptying the disk cache.

You can save space on the hard drive by decreasing the size of the Internet disk cache. See your browser’s Help files for instructions.

Emptying the Recycle Bin

In Windows, when you delete a file from your hard drive it is not immediately removed from the hard drive. Instead, the file is moved into the Recycle Bin. Because files are stored in the Recycle Bin and not deleted from the hard drive immediately, you can retrieve a file that you accidentally delete from the hard drive.

To delete all the files from the Recycle Bin, right-click the on the desktop, then select

You can save space on the hard drive by decreasing the size of the Recycle Bin.

6 Click OK.

74 Managing Your System

System integrity

Your system must be protected against electrical problems and physical hazards such as heat, moisture, and dust. Also protect it against less obvious hazards such as viruses.

Protecting against viruses

A virus is a program written with malicious intent for the purpose of creating havoc in a computer system.

Viruses spread through executable files, document macros, or boot sectors. Diskettes used in a contaminated computer can get a virus and transfer the virus when used in another computer. A virus can also spread through files downloaded from bulletin boards or the Internet.

Some viruses may only cause your system to beep or display messages or images on the screen. Other viruses are highly destructive, and corrupt or erase the contents of your files or diskettes. To be safe, never assume any virus is harmless. Always protect your system against viruses.

To protect your system against viruses:

■ Use an anti-virus program to scan your computer regularly. Make sure

to update the program periodically to keep up with new viruses.

■ Make backup copies of all files and write-protect the diskettes. A virus

cannot infect a write-protected diskette.

■ Obtain all software from reputable sources and always scan new software

for any viruses before installing it.

■ Be cautious about files you receive in e-mail or download from a network

or the Internet. If you download a file, use your anti-virus program to scan the directory on your computer that contains the downloaded file before you open the file.

■ If you have doubts about the source of a Microsoft

disable the file macros before opening the file. Word and Excel are set by default to warn you if a document you are about to open contains a macro that might have a virus.

■ If a power strip is used, it is turned on, and the circuit breaker is set.

■ The voltage selection switch on the system power supply reflects the

proper voltage.

Verifying yourconfiguration

If your system is not operating correctly, the BIOS may contain an invalid configuration parameter. Enter the BIOS Setup utility program and check your configuration settings.

Troubleshootingguidelines

As you troubleshoot your system, keep the following guidelines in mind:

■ Never remove the chassis cover while the computer is turned on.

■ Do not attempt to open the monitor. Even if the monitor’s power is

disconnected, stored energy within the monitor’s components can offer a painful or harmful shock.

■ If a peripheral, such as the keyboard, mouse, drive, or printer does not

appear to work, make sure that all connections are secure.

■ If an error message displays on the screen, write it down, word for word.

You may be asked about it when calling technical support.

■ Only qualified personnel should open the system for maintenance.

■ If you are qualified to maintain the system yourself, make sure you are

properly grounded before opening the system chassis. See “Static electricity precautions” on page 17 for more information on preventing electrostatic damage to the system.
