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 24
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.)
