Chapter 4. Troubleshooting Troubleshooting If you do not find your problem here, see Chapter 1. The following section only describes problems that might negate the need to refer to the more comprehensive information in Chapter 1.

The screen goes blank while the computer is on. • If the screen is blank, make sure that: - The AC power adapter is connected to the computer and the power cord is plugged into a working electrical outlet. - The computer power is on. Press and hold the Power button for about three seconds for confirmation. - Press and hold the Power button for about ten seconds to force shut down the computer. Then press the Power button for about three seconds to restart. • If these items are set correctly and the screen remains blank, have the computer serviced. • Your power management is enabled. Do one of the following to resume from sleep mode: - Press any key on the keyboard (located on the keyboard dock). - Press the Power button. - Press the Windows button. Sleep problems The critical low-battery error message appears, and the computer immediately turns off. • The battery power is getting low. Connect the AC power adapter to the computer.
