There are many facters for a problems with recharging your controller.
1. the usb port may be less then 2.0
2.the controller may have been faulty.
3. battery may have been ruind by heat or cold during its time at the shops.
4. you have dropt or mistreated it and a wire or and the battery has disconnected.
if you purchased it and as soon as you got home and tryd to reacharge it it may because of some of the resons above. your best bet would be to return it and if they do not take it back try opening it up an checking for loose wires if you dont see any loose wires try replacing the battery.
Hey I have had this problem at my friends house when I tried to use the controller there and I have found after the new update it has fixed it self try updating if you haven't.
ive had the same problem with my ds3 controllers...they wouldnt charge on ps3 or computer...although my old sixaxis charged no problems...a friend brought over a gharging dock that plugs into an electrical outlet instead of the usb port on a computer/ps3...both ds3's charge fine...so since its 2 seperate controllers and it solved them both...i recomenned trying that...hope this helps...good luck
I've had my PS3 for just over a year now and the controller charged fine.
Yesterday i was playin but had to do something quick so i left, came back, but didnt notice that is was on low battery. When i finally realised this moring i put it on charge. But instead of a battery with bars in it, it came up with a -. Now when im playin every 15 secs or so it comes up with "Please reconnect controller 1" i've tried charging on pc/laptop: still will not work. And personally i don't want to buy a £35-£40 controller and i dont want to have to buy an unofficial 1 or one from hong kong on ebay1
Is it just the fact the controllers a year old or is it something else?
Have you tried resetting the controller via the small pin hole on the back ? Stick a paperclip or similar in there to completely reset the controller and then try connecting it up via usb cable to the PS3. I have never had these issues but I always use a Pelican stand charger to charge my DS3's...
