Acer c510 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 your Acer C510
You may have to perform a reset if your Acer C510 no longer responds to the buttons on the screen.
Performing a soft reset
A soft reset allows your Acer C510 to get a fresh start, similar to rebooting a computer. All records and entries are retained after a soft reset.
To perform a soft reset:
• Using the tip of your stylus, lightly press the Reset button inside the hole on the upper right-hand side of your Acer C500.

Be careful with sharp edge
Performing a hard reset
A hard reset will erase all records and entries stored in your Acer C510. Never perform a hard reset unless a soft reset does not correct your problem. When you perform your next ActiveSync operation, you can restore any data that you previously synchronized to your computer.

1 Press and hold the Today and Messaging (a) buttons on your Acer c510
Series.
2 While holding the Calendar and Contacts buttons, using the tip of your stylus, lightly press the Reset button inside the hole (b) on the upper right-hand side of your Acer C510.

NOTE: When
you perform a hard reset, formats, preferences and other settings
including date and time are restored to their factory default settings.
All data, records and entries, except for those stored in ROM, will be
erased.
