What should I do if my Acer Iconia A3-A10 tablet won't turn on and won't charge?

Question

Accepted Answer

If your Acer Iconia A3-A10 tablet won't turn on and won't charge, start by plugging the official charger provided into the Micro USB port at the bottom of the device, then insert the other connector into a different wall outlet to isolate any potential electrical issue. The battery may be completely drained after a long period of inactivity.

Leave the tablet to charge for at least 4 hours without trying to turn it on. It is normal for the device to remain silent and for the screen to stay black during this phase. The surface of the tablet may warm slightly, which is perfectly normal during charging.

After 4 hours, press and hold the power button for 10 to 15 seconds until you see the Acer logo appear. Then release the button to allow the tablet to start up completely. This process may take a few seconds.

If the tablet still shows no signs of life, test the charger on another electrical outlet and check the condition of the Micro USB cable for any physical damage. You may also try another 5.35V/2A adapter if you have one available.

If despite these steps the screen remains black and the tablet does not respond, it is possible that the lithium-polymer battery (3540 mAh) is faulty or that the system is frozen. Gently press with a small thin object like a paperclip into the reset hole located above the power button to force a system reset. Then press the power button to restart. If this does not resolve the issue, contact an authorized Acer service center for a thorough diagnosis.
