Problem: When I turn on the machine, nothing appears on the screen and the

machine does not beep while starting up.

Note: If you are not sure whether you heard any beeps, turn off the

computer; then turn it on again, and listen again. If you are using an

external monitor, refer to“Computer screen problems” on page 20

Solution: If a power-on password is set, press any key to display the

power-on password prompt, and then type the correct password and press

Enter.

If the power-on password prompt does not appear, the brightness level might

be set to minimum brightness. Adjust the brightness level by pressing the

Fn+Home.

If the screen still remains blank, make sure that:

v The battery is installed correctly.

v The ac adapter is connected to the computer and the power cord is plugged

into a working electrical outlet.

v The computer power is on. (Turn on the power switch again for

confirmation.)

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

computer serviced.

Problem: When I turn on the machine, nothing appears on the screen, but I

hear two or more beeps.
