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 straightened paper clip into the emergency-reset hole to reset the tablet. Then restart your tablet.
To locate the emergency-reset hole, see “Tablet layout” on page 1.
If you still encounter the same problem after you restart your tablet, reset your tablet and restart it again,
you can perform a factory data reset operation. For more information, refer to “Restoring your tablet to
the factory default state” on page 41.
