•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.Tap the Power plan tab, and then select Maximum Performance from the predefined power plans.

•Problem: When I turn on the tablet, nothing is displayed on the screen and the tablet does not beep while starting up.

Note: If you are not sure whether you heard any beeps, turn off the tablet by pressing and holding the power button for four seconds or more. Turn it on and listen again.

Solution: Ensure that:

–The ac power adapter is connected to the tablet and the power cord is plugged into a working electrical outlet.

–The tablet 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 Home.

–Type the correct password and press Enter.

If these items are correctly set, and the screen remains blank, have the tablet serviced.

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 mSATA solid-state drive by using the software, and recover the partition if required.

–Use the recovery discs to restore the system to the factory state.

If the problem persists, have the tablet serviced.
