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 16.

Solution: If a user password is set, press any key to display the user password prompt, and then type 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+F11.

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.)

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.

Solution: Make sure that the memory card is installed correctly. If it is, but the screen is still blank, and you hear five beeps, have the computer serviced.

Problem: My screen goes blank while the computer is on.

Solution: Your screen saver or power management may be enabled. Touch the touch pad, or press a key to exit the screen saver, or press the power switch to resume from standby or hibernation mode.
