MAINTENANCE / SERVICE
Cleaning
Wipe the exterior with a clean, soft, and lint-free cloth. If there is difficulty to
remove dirt, apply non-ammonia, non-alcohol based glass cleaner onto the cloth.
An air gun is recommended for cleaning water and dust. For salty water
please clean with fresh water then blow-dry with an air gun. Be sure not to
turn the computer up side down while there is water being applied.
ALWAYS turn OFF the power, unplug the power cord and remove the
battery before cleaning.
Troubleshooting
Should the computer failed to function properly, you may try the following to
troubleshoot it.
Check AC/vehicle adapter, battery, and the power source.
Minimize the configuration, i.e., remove extra peripherals and devices.
Remove the modules one by one (HDD, CD-ROM, FDD, Battery, etc.).
Remove the software suspected.
Set BIOS fail-safe default.
Re-install operating system and application software.
RMA Service
If all of the user troubleshooting approaches still cannot help, consult the dealer
for service. When sending out the computer, please follow the re-packing guides:
Remove the CD/diskette (if any) in the CD-ROM/floppy disk drive.
Use the original shipping container and packing materials if possible.
When not using the original packing material, wrap the equipment with
soft material (e.g., PU/ PE form) then put it into a hard carton.
Secure the separate parts so they would not mix together during
transportation.
