Problem Cause and action
The setup password
prompt
If the setup password prompt appears when you press F1 to access the BIOS
Utility, a setup password is set.
Type the correct password and press Enter to use the computer (see the on-
board help).
Attention: If you forget your setup password, you have to take your computer to
an IBM reseller or IBM marketing representative to have the password reset.
Proof of purchase is required, and an additional charge might be required for the
service.
If you still have a problem, have the computer serviced.
The DOS full-screen
looks smaller.
When you use a DOS application that supports only the 640x480 resolution (VGA
mode), the screen image might look slightly distorted or might appear smaller than
the display size. This is to maintain compatibility with other DOS applications. This
is not a defect.
To expand the screen image to the same size as the actual screen, enter the
BIOS Utility and enable the Screen Expansion parameter in the Startup Config-
uration menu. (The image might look slightly distorted.) See
Online User's Guide
for more details.
The Windows startup
screen does not fill the
screen.
When you enable Screen Expansion in the Startup Configuration menu of the
BIOS Utility, the Windows startup screen expands but does not fill the entire
screen. This is not a defect. (The image might look slightly distorted.) See
Online
User's Guide
for more details.
Hibernation error The system configuration changed between the time your computer entered
hibernation mode and the time it left this mode, and your computer cannot resume
normal operation.
Restore the system configuration to what it was before your computer entered
hibernation mode.
If the memory size has been changed, re-create the hibernation file using the
Sleep Manager program.
Operating system not
found.
Verify the following:
The hard disk drive is correctly installed.
A startable diskette is in the external diskette drive.
If you still see the same error message, check the boot sequence using the BIOS
Setup Utility.
