Also, the computer goes into hibernation mode
automatically in either of the following conditions:
v
If a “hibernation time” has been set on the timer, and the
user does not do any operation with the keyboard, the
TrackPoint, the hard-disk drive, the parallel connector, or
the diskette drive within that time.
v
If the timer conditions are satisfied in suspend mode.
v
If you are using the APM operating system and have set
the mode to Hibernate when battery becomes low,
and the battery charge becomes critically low.
When the power is turned on, the computer returns from
hibernation mode and resumes operation. The hibernation
file in the boot record on the hard-disk drive is read, and
system status is restored from the hard-disk drive.
Checkout guide
Use the following procedures as a guide in identifying and
correcting problems with the ThinkPad computer.
Note: The diagnostic tests are intended to test only IBM
products. The use of non-IBM products, prototype
cards, or modified options can lead to false
indications of errors and invalid system responses.
1. Identify the failing symptoms in as much detail as
possible.
2. Verify the symptoms. Try to re-create the failure by
running the diagnostic test or by repeating the
operation.
Testing the computer
The ThinkPad computer has a test program called
PC-Doctor
®
DOS (hereafter called PC-Doctor). You can
detect errors by running the diagnostics test included in
PC-Doctor. This section is an overview of the procedure.
For details that depend on model-unique functions, refer to
“Product overview” on page 47.
For some possible configurations of the computer,
PC-Doctor might not run correctly. To avoid this problem,
you need to initialize the computer setup by use of the IBM
BIOS Setup Utility before you run PC-Doctor. On the IBM
BIOS Setup Utility screen, press F9, Enter, F10, and then
Enter.
Note: When you initialize the computer configuration,
some devices are disabled, such as the serial port.
If you test one of these devices, you will need to
enable it by using PS2.EXE.
