Hi ,all

         My board is IMX53, Windows Compact Embedded7 OS. Generally the board is good, when press the power button once, the system will suspend, going to the sleeping mode ; then press power button  again ,the WinCE7 system will restore. Press the power button for a longer time , about 4seconds, the system will be shut down ,the screen is off. Now the problem is that if I press the power button for less than 4 seconds, the screen still have backlight, and the first time I restart the board ,then the  touch function is out of effect. Every time I come across this problem,I will restart the system twice, and the WinCE7 system touch function will restore normal. the power management chip is DA9053.

   I doubt the unormal shutdown will affect the touch screen driver loading. Or the power management is should configured . But I don't know how to change or which files should I change.  Now I am confused by this problem. Sincerely hope U help me or tell me the method to cope with this problem.

Thanks a lot.
