Hey everyone,

Don't post much because usually all the info I need is found through search.  In any event, can't find the fix/reason for this one

Just the past week, everytime I put the PSP into sleep, and try to wake it back up, the power light flickers green and then turns off.  If i flick the power button again - the PSP resets to the Sony splash screen.

I've eliminated the possibility of software error because I upgraded to 3.90 M33 the day it dropped and this just began recently.  It occurs no matter what homebrew I'm running.  Reset Flash1 just in case some funny config setting was causing it, but to no avail. 

Is there a hardware malfunction that I haven't heard about with the power button?  Any advice is appreciated.

P.S.  Don't say "Are you sure you aren't holding the button too long and turning it off?" etc...I've had my PSP since release day and this has never happened...Thanks
