Acer P700 hard reset
Before
you buy a new cell phone or new tablet, please try the following
procedure to repair your device. First charge your battery, backup your
important data if possible and in most cases take out SIM and SD card.
It is impossible to recover your data after doing a hard reset, so
online backup is always important. For all of your data, a backup should
be done on an external device, hard drive, raid system or media.
Resetting the Acer p700 Series Portable Navigator
You may have to perform a reset if the device freezes (i.e., device no longer responds to the buttons on the screen). A soft reset allows your device to get a fresh start, similar to rebooting a computer. This will restart your device and adjust memory allocation. All records and entries are retained after a soft reset. GPS settings are also retained.
Performing a soft reset
Hold the device securely, and slide switch the soft reset button on the bottom left of your device.

NOTE: Performing a hard reset will clear the RAM in the unit and reset the GPS of the unit.
