Thread: Touch HD Screen time out does not work

This is a HUGE problem i face , screen automatic time out never works , you can imagine when some gives me a missed call for example while I am sleeping and I do not answer , the screen keeps ON and light never goes off , so when I wake up in the morning I find my touch HD complete shut down due to power is gone , this is a Battery killing problem ,

plse advise me how to solve this , I will be very grateful .
