The timer conditions are satisfied in suspend mode
(for operating systems other than Windows 98).
A critically low battery condition occurs and mode is
set to Hibernate when battery becomes low.
When the power is turned on, the computer leaves
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.

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 13.
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 Easy-Setup
before you run PC-Doctor. In the Easy-Setup screen, click
Config and Initialize.
Note: When you initialize the computer configuration,
some devices are disabled, such as the serial port.
If you test one of these devices, you need to
enable it by using PS2.EXE.
PC-Doctor does not support the test for the device in the
SelectaDock docking station.
You can test the device in the docking station with an
advanced test in Easy-Setup that is supported by the
ThinkPad 600, 600E, or 770x series.
To run such a test,
Remove a device from the bay of the docking station
and install it in the bay of the 600 or 600E computer.
Then start Easy-Setup.
