Standby or hibernation problems

Problem:

The computer enters standby mode unexpectedly.

Solution:

If the processor overheats, 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:

vThe battery is charged.

vThe 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.

Problem:

The computer does not return from standby mode, or the standby indicator stays on and the computer does not work.
