Avoid leaving the base of your computer, or any other part that
becomes hot during operation, in contact with your lap or any
part of your body for an extended period when the computer is
turned on or when the battery is charging.
When the ac adapter is connected to an electrical outlet and your computer, it
generates heat. Do not place the adapter in contact with any part of your
body while using it. Never use the ac adapter to warm your body. Extended
contact with your body, even through clothing, may cause a skin burn.
Route the cables of an ac adapter, a mouse, a keyboard, a printer, or any
other electronic device, or any communication lines, so that they cannot be
pinched by your machine or other objects, walked on, tripped over, or in any
way be subjected to treatment that could disturb the operation of your
computer. Applying strong force to the cables may damage or break them.
To prevent damage to the hard disk and subsequent data loss,
before moving your computer, press Fn+F4 to put it in standby
mode or turn it off. Make sure that the standby status indicator
is on (is green) before moving the computer.
Do not drop, bump, scratch, twist, hit, vibrate, push or place
heavy objects on your computer, display, or external devices.
Use a quality carrying case that provides adequate cushion and
protection. Do not pack your computer in a tightly packed
suitcase or bag.
Place liquids away from your computer to avoid spills, and
keep your computer away from water to avoid the danger of
electrical shock.

level. Extended contact with your body, even through clothing, could cause
discomfort or, eventually, a skin burn.

Troubleshooting
If you do not find your problem here, refer to Access Help, your on-board
help system. The following section only describes problems that might
prevent you from accessing this help system.
Error messages
The following is a list of the messages that the 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 one of the messages marked below with an asterisk (*), write
down the message and contact your marketing representative. If your system
fails after you make changes in the BIOS Setup Utility menus, reset the
computer, enter BIOS Setup Utility and configure default settings or correct
the error.
Code Message Description
0200 Failure Fixed Disk Fixed disk is 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.

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, charge the system battery more
than 8 hours by connecting the ac adapter, or contact your
dealer.

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.
