Solving computer problems

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 pack with a fully charged one.

Problem: The computer display remains blank after you take action to return from a sleep mode.

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.

Solution: The computer automatically enters standby or hibernation mode when the battery is depleted. Do one of the following:

Problem: When you are using the port replicator, resuming normal operation from hibernation or standby mode takes a long time.

Solution: If the Ethernet port is enabled, but the port replicator is not connected to a network, resuming operation can take a long time.

If you are not using the network, disable the Ethernet port as follows:
