Troubleshooting ----------------------------------------------------------------------------

If you do not find your problem here, see Chapter 2. The following section only describes problems that might prevent you from accessing the comprehensive information in Chapter 2.

Display Problems

When I turn on the computer, nothing appears on the screen.

Note:

If you are using an external monitor, See “Computer Screen Problems” on page 43.

If a user password is set, enter the correct password and press Enter.

If the user password prompt does not appear, the brightness level might be set to minimum brightness. Adjust the brightness level by pressing Fn + .

If the screen still remains blank, make sure that:

-The battery is installed correctly.

-The AC adapter is connected to the computer and the power cord is plugged into a working electrical outlet.

-The computer power is on. (Press the power button again for confirmation.)

If these items are properly set, and the screen remains blank, have the computer serviced.
