My Acer Iconia A500 hasn't been working for a while now, and only now have I decided to fix it. I dismantled it completely, and discovered it was to do with the power button, this is a known issue with this tablet. So I put it back together, confident that I could turn it on by shorting the contacts. However, I plugged it in, it indicated it was charging with the charging light, and shorting the contacts did nothing. To short it I put a piece of Aluminium foil in some tweezers and put it on the contacts. Am I doing something wrong here? Or does shorting the contacts not turn it on?
