hello. i recently purchased a gp2x from gp32z.com. i am considering returning it, because i believe it has a flaw. if i so much as play a game for 5 minutes, then turn off the gp2x, then turn it on five or ten seconds later, it will not cone on. i have to replace the batteries with fresh ones. i feel that this is not normal. should i return this gp2x?
