tady jsou ještě nějaké rady co jsem pročetl:

yeah i had this problem too until i decided to reset the controller by usnig a pin needle and pressing the little hole behind the PS3 controller. after that resync and when you turn on the PS3 make sure the controller is really close to the PS3 and you should not have any problems.

reset the controller, there is a small hole on the mid/righ top of the back of the controller, get a paperclip, bend it, and hit the button inside the hole
then plug it in, presss ps button
unplug it
press ps button again
