Power button issues on my CDMA touch pro

[Phil_00]

I've recently noticed that after my device is left for periods of time and the backlight goes off and turns orff into its low power mode, i cant wake it up. I hit the power button and nothing happens. This issue is hit or miss, sometimes it works sometimes it doesnt. It makes using the alram clock on my device hard when its frozen in the morning. Anyone else expericning this issue?
