Is there any way you cna change the time limit of how long you need to hold the power button 'up' before it turns off? IMO, I think 10 seconds is kind of long. I would imagine 5 seconds would be plenty enough.
If I could change it, I would change it to 5 seconds or something. If not, then I guess 10 seconds will have to do. It just seems too long to hold the power button 'up' that long just to turn off the PSP (NOT for sleep mode, i mean actually turning the PSP off completely).
