Had it been dropped? Any damage around the button? If not they are a doddle to open. Find a video on say changing a battery or something to show you how. When you have access to the internals push the button back out from the inside. If the button is dirty use a cotton bud with some ipa or spray a bit of wd40 on the bud to clean it. Push the button a few times to clear any dirt. Hope it helps.
Hi @ghenaghen
What is the model number of the tablet as found on the back cover?
This is so the correct model can be identified.
