Sleep and hibernation problems

• Problem: The computer enters sleep mode unexpectedly.

Solution: If the microprocessor overheats, the computer automatically enters sleep mode to allow the

computer to cool and to protect the microprocessor and other internal components. Check the settings

for sleep mode.

• Problem: The computer enters sleep mode immediately after the power-on self-test.

Solution: Ensure that:

– The battery is charged.

– The operating temperature is within the acceptable range. See “Operating environment” on page 11.

If the problem persists, have the computer serviced.

• Problem: A critical low-battery error occurs, and the computer immediately turns off.

Solution: The battery power is getting low. Plug the ac power adapter into an electrical outlet and then

into the computer. Alternatively, replace the battery with a charged one.

• Problem: The computer display remains blank after you press Fn to resume from sleep mode.

Solution: Check whether an external monitor was disconnected or turned off while the computer was in

sleep mode. If you disconnected or turned off the external monitor, connect it or turn it on before resuming

the computer from sleep mode. When resuming the computer from sleep mode without attaching the

external monitor or turning it on, and the computer display remains blank, press the display-mode

switching key

to bring up the computer display.

• Problem: The computer does not resume from sleep mode, or the system status indicator blinks slowly

and the computer does not work.

Solution: If the system does not resume from sleep mode, it might have entered sleep or hibernation

mode automatically because the battery is depleted. Check the system status indicator.

– If the system status indicator blinks slowly, your computer is in sleep mode. Connect the ac power

adapter to the computer; then press Fn.

– If the system status indicator is off, your computer has no power or is in hibernation mode. Connect the

ac power adapter to the computer; then press the power button to resume operation.

If the system still does not resume from sleep mode, your system might stop responding and you might

not be able to turn off the computer. In this case, you must reset the computer. If you have not saved your

data, it might be lost. To reset the computer, press and hold the power button for four seconds or more. If

the system still does not respond, remove the ac power adapter and the battery.

• Problem: Your computer does not enter sleep or hibernation mode.
