This is from Acer for an A100 did it yesterday on my granddaughters tab it takes a few minutes

Performing a Factory data reset:

In order to restore it to factory settings, follow the below process:

  1. Shutdown the power (press the power button for long time to shutdown).

  2. Press and hold volume up key (the key next to rotation lock) until you finish step 4.

  3. Press power button for 3 seconds until you feel device vibrates then release power button.

  4. Once you feel device vibrates, very quick to switch on/off "rotation key" many times (this activity has to be done very fast, otherwise it will not success). To ensure you success, switch on/off rotation key when Acer logo appears on screen.

  5. Wait for a while (you will see Erase Userdata.... & Erase Cache... on top-left corner on screen), device will reboot and start from OOBE screen.
