• 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 tablet is connected to the ac power adapter by the supplied USB cable and the ac power adapter
is plugged into a working electrical outlet.
The tablet is turned on. (Turn the power button on again for confirmation.)
If these items are correctly set, and the screen remains blank, have the tablet serviced.
• Problem: When I turn on the tablet, only a white pointer is displayed on a blank screen.
Solution: Do the following:
1. Turn off the tablet, and then turn it on again.
2. If you still see only the pointer on the screen, use the recovery solutions to restore the system to
the factory state.
If the problem persists, have the tablet serviced.

Battery problem
• Problem: The battery does not charge correctly.
Suggested solution: Check if the ac power adapter is connected correctly. If the connection is good but
the battery still does not charge, contact Lenovo to replace with a new battery.
System problem
• Problem: Unable to turn the tablet on.
Suggested solution: Connect your tablet to an ac power outlet to see if the problem is caused
by a drained battery. If the problem persists, insert a needle or a straightened paper clip into the
emergency-reset hole. To locate the emergency-reset hole, see "Front view and side view" on page 1.
If the problem still persists, contact Lenovo for technical support.
Media problems
• Problem: The audio quality is poor or there is no sound output.
Suggested solution: Check and ensure that:
– The speaker is not covered.
– The speaker mute function is disabled.
