Hey everyone,
So I charged my PlayBook to 100% today and then I accidently pressed the "turn off" instead of "lock", closed my convertible case cover and went out. 4 hours later when I came back, I opened the cover case and noticed the screen backlight was still turned ON but playbook wasn't responsive. I had to do a hard reset (vol+ Vol - power) and it completely shut off.
I had exactly same problem a week before. In my case the back light was on and the unit got heated. The battery was completely drained from fully charged unit with in a short time. I had no option but return and refund from PC world. I liked the PB but if it is not doing what is expected to do then there is no point of keeping it. By the way the OS was 2.
I'm running OS .668 and something similar happened to me as well. A few weeks ago I hit turn off and went to bed and when I went to turn my pb back on in the morning and pressed the button, my pb screen immediately popped up. It had never turned off at all. I didn't have to do a reset or anything but it baffles me that it didn't turn off. Hasn't happened again but I find myself rechecking it before I go to bed these days.
