Errors without messages

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 by pressing and holding the power button for more than 4 seconds; then turn it on and listen again. If you are using an external monitor, refer to “Computer screen problems” on page 21

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:

vThe battery is installed correctly.

vThe ac adapter is connected to the computer and the power cord is plugged into a working electrical outlet.

vThe computer power is on. (Turn on the power switch again for confirmation.)
