so I figured out that my 1.5 psp wont sleep/turn off during any game or homebrew, even umd, it just turns back on after 1 second. however in xmb this does not happen. thought flash was messed up, so i upgraded to 2.00, and it was still happening. then i downgraded back to 1.5 and its still happening. suggestions? about to go oe-b
