10.3. Display and screen problems
When I turn on the device, nothing appears on the screen.
If the screen is blank, make sure that:
• The AC adapter is connected to the tablet and the power cord is plugged into a working electrical
outlet;
• The device is turned on (press the power button again for confirmation for 6 seconds to force the
turn off and on of the tablet).
If these items are properly set, and the screen remains blank, the device needs service.
The screen goes blank while the device is on.
If the screen turns black while the tablet is functioning, that means that it is in the sleep mode. To
turn it back on, press the power button.
The screen is unreadable or distorted.
Make sure that:
• The screen resolution and color quality are correctly set;
• The monitor type is correct.
Incorrect characters appear on the screen.
Are the operating system or programs installed correctly? If they are installed and configured
correctly, have the DEVICE serviced.
The screen is blank.
If the AC adapter is connected, or if the battery is used, and the battery status indicator is on, press
F6 to make the screen brighter.
Press the power button to resume from sleep mode.
If the problem persists, check if the screen resolution and color are correctly set, or of the monitor
type is correct.

The critical low-battery error message appears, and the device turns off.
The battery power is getting low. Connect the AC adapter to the device.
The device enters sleep mode immediately after Power-on.
Make sure that the battery is charged. The operating temperature may also be too hot. Move it to
a cooler environment and try to wake the device.
The device does not return from sleep mode and the device does not work.
Connect the AC adapter, then press the power button. If your device is powered-off, connect the
AC adapter first, and then press the power button to resume operation.
