CHAPTER 2

PGRADING COMPONENTS

This chapter describes how to upgrade components for the PT-6800. The following topics are described.

• “Safety and precautions”

• “Before you begin” on page 12

• “Installing a hard disk drive (HDD)” on page 12

• “Installing a CompactFlash card” on page 14

Safety and precautions

Computer components and electronic circuit boards can be damaged by discharges of static electricity. Working on computers that are still connected to a power supply can be extremely dangerous. Follow these guidelines to avoid damage to the computer or injury to yourself.

• Always disconnect the unit from the power outlet.

• Leave all components inside the static-proof packaging that they ship with until they are ready for installation.

• After replacing optional devices, make sure all screws, springs, or other small parts are in place and are not left loose inside the case. Metallic parts or metal flakes can cause electrical shorts.

CAUTION

WARNING

CAUTION

Only qualified personnel should perform repairs on the PT-6800. Damage due to unauthorized servicing is not covered by the warranty. If you are not confident of installing a hard drive or CompactFlash card, we recommend that you refer the job to qualified personnel.

If the LCD breaks and fluid gets onto your hands or into your eyes, immediately wash with water and seek medical attention.

The inverter card has high voltage. Do not touch the inverter card while power is connected to the PT-6800. Unplug the power cord before attempting to replace any part.

To prevent static damage to components, wear a grounded wrist strap. Alternatively, discharge any static electricity by touching the bare metal chassis of the unit case, or the bare metal body of any other grounded appliance.

Hold electronic circuit boards by the edges only. Do not touch the components on the board unless it is necessary to do so. Do not flex or stress the circuit board. Do not hold components such as a processor by its pins; hold it by the edges.

Before you begin

Make sure you have a stable, clean working environment. Dust and dirt can get into components and cause a malfunction. Adequate lighting and proper tools can prevent you from accidentally damaging the internal components.

Most of the electrical and mechanical connections can be disconnected by using your fingers. It is recommended that you do not use needle-nosed pliers to disconnect connectors as these can damage the soft metal or plastic parts of the connectors.

To prevent scratching the case of the PT-6800, make sure the worktop surface is clean and flat.

DRAM Timing

Set this to the default value to enable the system to automatically set the SDRAM timing by SPD (Serial Presence Detect). SPD is an EEPROM chip on the DIMM module that stores information about the memory chips it contains,

including size, speed, voltage, row and column addresses, and manufacturer. The default value is By SPD.

When the DRAM Timing setting is set to “Manual” the fields that previously had an “x” before them become available.

NOTE

DRAM CAS Latency

This item enables you to specify the time delay (in clock cycles or CLKs) that elapses before the SDRAM carries out a read command after receiving it. The value specified here also sets the number of CLKs that will elapse for the completion of the first part of a burst transfer. Low values indicate a faster data transaction. When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. The default is 2.5.

Bank Interleave

Enable this item to increase memory speed. When enabled, separate memory banks are set for odd and even addresses and the next byte of memory can be accessed while the current byte is being refreshed. The default is Disabled.

Precharge to Active(Trp)

This item is used to designate the minimum Row Precharge time of the SDRAM devices on the module. DRAM must continually be refreshed or it will lose its data. Normally, DRAM is refreshed entirely as the result of a single request. This option allows you to determine the number of CPU clocks allocated for the Row Address Strobe (RAS) to accumulate its charge before the DRAM is refreshed. If insufficient time is allowed, refresh may be incomplete and data lost. The default is 3T.

Active to Precharge(Tras)

This item specifies the number of clock cycles needed after a bank active command before a precharge can occur. The default is 6T.

Active to CMD(Trcd)

This item specifies the minimum required delay between activation of different rows. The default is 3T.

DRAM Command Rate

This item enables you to specify the waiting time for the CPU to issue the next command after issuing the command to the DDR memory. We recommend that you leave this item at the default value. The default value is 2T Command

on and off by external devices, so that mouse or keyboard activity wakes up the PT-6800.

Use this item to define how the system suspends. In the default, S1(POS), the suspend mode is equivalent to a software power down. If you select S3(STR), the suspend mode is a suspend to RAM - the system shuts down with the exception of a refresh current to the system memory. The default setting is S1(POS).

Power Management Option

This item acts like a master switch for the power-saving modes and hard disk timeouts. If this item is set to Max Saving, power-saving modes occur after a short timeout. If this item is set to Min Saving, power-saving modes occur after a longer timeout. If the item is set to User Define, you can define timeouts for the power-saving modes. The default setting is Min Saving.

HDD Power Down

The IDE hard drive will spin down if it is not accessed within a specified length of time. Options are from 1 Min to 15 Min, and Disabled. The default setting is Disabled.

Suspend Mode

The CPU clock will be stopped and the video signal will be suspended if no Power Management events occur for a specified length of time. Full power function will return when a Power Management event is detected. Options are from 1 Min to 1 Hour and Disabled. The default setting is Disabled.

Video Off Option

This option defines if the video is powered down when the system is put into suspend mode. The default setting is Suspend -> Off.

Video Off Method

This item defines how the video is powered down to save power. The default setting is V/H SYNC+Blank.

Soft-Off by PWRBTTN

Under ACPI (Advanced Configuration and Power management Interface) you can create a software power down. In a software power down, the system can be resumed by Wake Up Alarms. This item lets you install a software power down that is controlled by the normal power button on the system. If the item is set to Instant-Off, then the power button causes a software power down. If the item is set to Delay 4 Sec. then you have to hold the power button down for four seconds to cause a software power down. The default setting is Instant-Off.

APPENDIX

This appendix describes locating and solving problems that you may encounter while using the PT-6800.

Troubleshooting

Often after time spent troubleshooting, the problem is traced to something as simple as a loose connection. Check the following before proceeding to the problem-specific solutions.

Tips for Troubleshooting

In each problem-specific section, try the steps in the order suggested. This may help you to solve the problem more quickly.

Try to pin point the problem and thus avoid replacing non-defective parts. For example, if you replace batteries and the problem remains, put the original batteries back and go to the next step.

Keep a record of the steps you take when troubleshooting: The information may be useful when calling for technical support or for passing on to service personnel.

• Use some other electrical device to confirm that the electrical outlet is working.

• Ensure all connections are securely attached.

The Power-On Self Test

The Power-On Self Test (POST) runs every time you turn on or reset the computer. The POST checks memory, the mainboard, the display, the keyboard, the disk drives, and other installed options.

If failure is detected in an area other than the mainboard (such as the keyboard or an adapter card), an error message is displayed on the screen and testing is stopped.

If your system does not successfully complete the POST, but displays a blank screen, have the PT-6800 serviced.

Beep Errors at POST

There are two kinds of beep codes in the BIOS.

• Video error - a single long beep followed by three short beeps indicates a video error, the screen can not be initialized and no information can be displayed.

• DRAM error - a single long beep indicates that a DRAM error has occurred.

Beep Message Errors at POST

If the BIOS detects an error during the POST, a message is displayed. Refer to the following table for a list of the errors that display.

The system uses a 3V CR2032 battery (CMOS battery) mounted on the mainboard to keep time. There is a risk of explosion if the wrong battery type is used when replacing. Dispose of used batteries according to local ordinance regula-
