For all areas
This equipment is classified as a class 1 level LASER product and there is no hazardous LASER radiation.
Caution:
(1) Use of controls or adjustments or performance of procedures other than those specified herein may result
in hazardous radiation exposure.
(2) The drive is designed to be incorporated into a computer-based system or unit which has an enclosing
cover. It should never be used as a stand alone drive.
Danger:
The serviceman should not remove the cover of drive unit and should not service because the drive unit is a
non-serviceable part.
Please check DANGER label on bottom cabinet of the equipment.
.Unplug the AC power cord and remove the battery pack from the equipment before opening the top cover of
the drive.
.When the power switch it on, do not place your eyes close to the top cover to look into the interior of the unit.

A lithium ion battery that is recyclable powers the product you have purchased.
Please call 1-800-8-BATTERY for information on how to recycle this battery.
L’appareil que vous vous êtes procuré est alimenté par une batterie au lithium-
ion. Pour des renseignements sur le recyclage de la batterie, veuillez composer
le 1-800-8-BATTERY.

This computer has been designed so as to minimize shock to the LCD and hard disk drive, etc.,
but no warranty is provided against such trouble. Therefore, as a precision instrument, be
extremely careful in the handling.
Do not carry the computer while the display is open, or carry it by gripping the display or the
cabinet around the display (see figure A). When closing the display, ensure that the latch is
positioned correctly in the slot .
Do not carry your computer when the power is on.
Do not drop or hit your computer against solid objects.
Remove all external devices, cables, PC Cards sticking out of the computer (see figure B),
SD memory cards, and MultiMedia Cards before transporting the computer .
We recommend preparing a fully charged battery pack.
When transporting a spare battery pack inside a package, briefcase, etc., it is recommended
that it be placed in a plastic bag so that its contacts are protected.
Always carry your computer with you. Never check it in with luggage. For use of the com-
puter inside an aircraft, we recommend asking the airlines regarding their policy on this issue.
It is a good idea to make backup copies on disks and carry them with you.

B
Touch Pad
Display
Avoid using water when cleaning the panel. Ingredients included in water may leave scratches
and reduce readability of the screen.
<When cleaning dust/dirt>
Avoid rubbing off dust/dirt with cloth since it may leave scratch on the screen.
Sweep dust/dirt with fine brush, then wipe it with a dry soft cloth used for cleaning glasses.
<When cleaning oily surface>
Apply camera lens cleaner on a soft gauze and clean it with gentle force. Then, wipe with a
dry soft cloth used for cleaning glasses.
Areas excluding the display
Wipe these areas with a soft cloth, after applying water or detergent diluted with water to the
soft cloth and firmly wringing out excess water.
Do not use benzene, thinner, or rubbing alcohol. Doing so may adversely affect the
surface, e.g., discoloration. In addition, do not use commercially-available household
cleaners and cosmetics, as they may contain components harmful to the surface.
Do not directly add or spray water or detergent. If liquid enters the inside of the
computer, it may cause it to work improperly or be damaged.

4 Diagnosis & Repair
4.1. Basic Procedures

4.2. Troubleshooting

Troubleshooting
The following is a list of the messages that BIOS can display. Most of them occur during POST. Some of them display
information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device,
such as the way it has been configured. Following the list are explanations of the messages and remedies for reported
problems.
If your system displays any of the below error messages other that the ones marked with an asterisk (*), write down the
message and contact your technical support office. If your system fails after you make changes in the Setup menus, reset
the computer, enter Setup and install Setup defaults or correct the error.
0200 Failure Fixed Disk
Fixed disk in not working or not configured properly. Check to see if fixed disk is attached properly. Run Setup.
Find out if the fixed-disk type is correctly identified.
0211 Keyboard error
Keyboard not working.
0212 Keyboard Controller Failed
Keyboard controller failed test. Requires repair of system board.
0213 Keyboard locked - Unlock key switch
Unlock the system to proceed.
0230 System RAM Failed at offset : nnnn
System RAM failed at offset nnnn of in the 64k block at which the error was detected.
0231 Shadow RAM Failed at offset : nnnn
Shadow RAM failed at offset nnnn of the 64k block at which the error was detected.
0232 Extended RAM Failed at offset : nnnn
Extended RAM Failed at address line : nnnn
Extended memory not working or not configured properly at offset or address line nnnn.
0250 System battery is dead - Replace and run SETUP
The CMOS backup battery is dead. Replace the battery and run Setup to reconfigure the system.
*0251 System CMOS checksum bad - Default configuration used
System CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in
CMOS. The BIOS installed Default SETUP Values. If you do not want these values, enter Setup and enter your own values.
If the error persists, check the system battery or contact your technical support office.
0260 System timer error
The timer test failed. Requires repair of system board.
0270 Real time clock error
Real-time clock fails BIOS test. Requires repair of system board.
0271 Check date and time settings
Real-time clock is illegal. Run Setup and set the date and clock.
*0280 Previous boot incomplete - Default configuration used
Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused
by incorrect values and they are not corrected, the next boot will likely fail. On systems with control of wait states, improper
Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that the wait-state
configuration is correct. This error is cleared the next time the system is booted.
02D0 System cache error - Cache disabled
Contact your technical support office.
Failing Bits : nnnn
The hex number nnnn is a map of the bits at the RAM address which failed the memory test. Each 1 (one) in the map indicates
a failed bit. See error 230,231 or 232 for offset address of the failure in System, Extended or Shadow memory.
Operating System not found
Operating system cannot be located on either drive A: or drive C:. Enter Setup and see if fixed disk and drive A: are properly
identified.
Press <F1> to resume, <F2> to Setup
Displayed after any recoverable error message. Press <F1> to start the boot process or <F2> to enter a Setup and change the
settings. Write down and follow the information shown on the screen.
