Iv had my playbook for just over a year, I have no warranty left. A few weeks ago I was charging my playbook and I noticed that it wasn't working properly and that I had to hold the charger in and up for it to charge and now a few days ago its stopped working, my battery has completely gone and I can't turn it on anymore, the charger works fine on other devices so I know it's not that, iv also tried other chargers and the USB that came with it. I managed to turn it on for a few minutes after it had first died and when I tried to charge it a notification appeared saying 'could not charge playbook with connected source' and then it died, now when I attempt to charge it a red light comes on for about 10 seconds and then a greeny yellow light flashes and then it does nothing, does anyone know what could be wrong and how I can fix it?
