Problem: The critical low-battery error message is displayed, and the computer
immediately turns off.
Solution: The battery power is getting low.
Do either of the following:
v Connect the AC adapter to the computer and plug it into an electrical outlet.
v Replace the battery with a fully charged one.
Problem: While operating with the battery, the computer does not return from standby mode,
or the standby indicator stays on and the computer does not work.
Solution: The system may have entered standby or hibernation mode automatically because
the battery is depleted.
1. Connect the AC adapter to the computer.
2. If the standby indicator is on, press any key. If the standby indicator is off, press
the power button to resume operation.
3. If you press Fn or the power button, and the system does not return from
standby or hibernation mode, the computer stops responding and cannot be
turned off:
a. Turn off the computer by pressing and holding the power button for 4
seconds or more. Unsaved data may be lost.
b. If the computer still does not respond, remove and reinstall the AC adapter
and the battery.
