The computer does not return from sleep mode and does not work.

•If the computer does not return from sleep mode, it may have entered hibernation mode automatically because the battery is depleted. Check the power indicator.

•If your computer is in sleep mode connect the AC adapter to the computer, then press any key or the power button.

•If your computer is in hibernation mode or power- off state. Connect the AC adapter to the computer, then press the power button to resume operation.

Note: If the system still does not return from sleep mode, your system has stopped responding, and you cannot turn off the computer, reset the computer. However, unsaved data may be lost. To reset the computer, press and hold the power button for 4 seconds or more. If the computer is still not reset, remove the AC adapter and the battery.
