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 External monitor problems.
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 control
lever might be set to minimum brightness. Adjust the brightness level by
pressing 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.
