So here's the problem I'm having... Some times when I turn off the screen on my nook, after a few minutes it won't wake back up. Neither the home button nor the power key will turn the screen back on. The only thing I can do is to hold the power key for 10 seconds our so which would normally turn it off, then release and hold the power button again for 10 seconds or so until the screen flashes and it begins to boot up from a powered off state. I cannot find any pattern to when it does this and I have re-wiped and reinstalled cm7 but it still happens about 2-3 times per day. Anybody else run into this?
