Now ,I find a problem of the iMX53 tablet PC, while I have a long press the power button until the Windows CE7 system is off and the power light is off. Then, Restart the Tablet is good . But I have a press the power button until the system is off ,but the power light is nont off. then the system has some problem,that is when restart the board , the touch screen function is useless. You have to restart tiwce to make sure the touch function is good.
Does it has something with the power management chips DA9053? THIS problem now even drive me crazy.
so , how can I get over this problem? Could any one tell me or analyze the problem for me ?
Thank s alot
