Screen and performance

The screen appears blank

When the device is on and idle, the screen first dims and then turns off. This is normal behavior, caused by the auto shut-off interval. You can adjust this auto shut-off interval to be as long as 10 minutes (see Set the interval for turning the screen off automatically). At first, the screen dims as a power-saving measure. Just tap the screen to brighten it. Then, if your device remains inactive for the full interval you set, the screen turns itself off. Press the power button to turn the screen back on.

Follow these steps in sequence if you can’t turn the screen back on:

1Make sure you have removed the protective cover that came attached to your device screen.

2Make sure that there are no stickers covering any part of the front of the device.

3To brighten the screen if it has dimmed, tap the screen.

4To turn on the screen, do one of the following:

•Press the power button. Drag up to unlock the screen.

•Press Center .

5Look closely at the screen. If the display appears but is faint, try adjusting the screen brightness (see Turn auto dim on/off).

6If the problem persists, connect your device to the AC charger (see Charge the battery). If you see a faint display, try to restart your device (see Restart your device).

7If you don’t see a display or the screen doesn’t respond to taps, press and hold both the power button and Center for 15 seconds to restart your device. Then wait until your device completes startup.

3Make sure the screen is not locked. Press the power button and drag

up to unlock the screen.

4Press Center . If the application screen minimizes to a card, throw the card off the top of the screen to close the app.

5If the screen does not respond to taps at all, press and hold both the power button and Center for 15 seconds to restart your device. Then wait until your device completes startup.

6If this does not solve the problem, see 5Ts: Ways to get your HP TouchPad working again for additional steps to try.
