• Problem: My screen keeps blanking when I do not want it to.
Solution: You can disable any system timers, such as the LCD turn-off timer or the blank timer by
doing the following:
1. Start Power Manager.
2. Click the Power plan tab, and then select Maximum Performance from the predefined power plans.
• Problem: When I turn on the computer, nothing is displayed on the screen and the computer 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 four seconds or more. Turn it on and listen again.
Solution: Make sure that:
– The battery is installed correctly.
– The ac power adapter is connected to the computer and the power cord is plugged into a working
electrical outlet.
– The computer is turned on. (Turn the power button on again for confirmation.)
If a power-on password is set:
– Press any key to display the prompt for the power-on password. If the brightness level of the screen is
low, increase it by pressing the key combination of Fn+F9.
– Type the correct password and press Enter.
If these items are correctly set, and the screen remains blank, have the computer serviced.
• Problem: When I turn on the computer, only a white cursor is displayed on a blank screen.
Solution: If you have modified a partition on your hard disk drive by using partition software, information
about that partition, or the master boot record might have been destroyed.
1. Turn off the computer, and then turn it on again.
2. If you still see only the cursor on the screen, do the following:
– If you have used the partition software, examine the partition on the hard disk drive by using the
software, and recover the partition if required.
– Use either the Rescue and Recovery workspace or the recovery discs to restore the system
to the factory state.
