Recovering from a severe software problem
If your tablet stops responding and you cannot turn off the tablet by pressing and holding the power button,
insert a needle or a straightened paper clip into the emergency-reset hole to reset the tablet. Then restart
your tablet. To locate the emergency-reset hole, see “Front view and side view” on page 1.
If you still encounter the same problem after you restart your tablet, reset your tablet and restart it again,
