Standby or hibernation problems
Problem:
The computer enters standby mode unexpectedly.
Solution: If the processor reaches a temperature that is too high, the computer
automatically enters standby mode to allow the computer to cool and to
protect the processor and other internal components. Also, check the settings
for standby mode, using Battery MaxiMiser.
Problem:
The computer enters standby mode immediately after Power-on
self-test (POST) (the standby indicator light turns on).
Solution: Make sure that:
v
The battery is charged.
v
The operating temperature is within the acceptable range. Refer to
“Specifications” on page 5.
If these items are correct, have the computer serviced.
Problem: The
critical low-battery error
message is displayed, and the
computer immediately turns off.
Solution: The battery power is getting low. Connect the ac adapter to the
computer, or replace the battery with a fully charged one.
Problem: When you take action to return from standby mode, the computer
display remains blank.
Solution: Check whether an external monitor was disconnected while the
computer was in standby mode. Do not disconnect the external monitor while
the computer is in standby mode or hibernation mode. If no external monitor
is attached when the computer resumes, the computer display remains blank
and output is not displayed. This restriction does not depend on the
resolution value. Press Fn+F7 to bring up the computer display.

indicator stays on and the computer does not work.
