Introduction

If your tablet does not turn on (even after being charged) or the battery does not last as long as it used to, the battery may need to be replaced.

This guide demonstrates how to replace the battery in your tablet.

Caution: Some images display the steps using a metal spudger. Use the heavy-duty spudger instead to avoid damaging your circuits.

I changed my battery and also the charging port/ribbon cable..... Could someone help me figure out why it still won't show anything on screen or turn on ? It's never been dropped, started having a problem with charging issues so decided it must be battery, port, or charger. So I bought all three and still no change ? help!!
