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 POST.
Solution: Make sure that:
– The battery is charged.
– The operating temperature is within the acceptable range. Refer to "Computer specifications" on
page 11.
If the battery is charged and the temperature is within range, have the computer serviced.
• Problem: A critical low-battery error occurs, and the computer immediately turns off.
Solution: The battery power is getting low. Connect the ac power adapter to the computer and to an
electrical outlet.
• Problem: The computer display remains blank after you press Fn to return 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 the sleep mode. When resuming the computer from the sleep mode
without attaching the external monitor or turning it on, and the computer display remains blank, press
F7 to bring up the computer display.
