PlayStation 3 controller does not work?

PlayStation 3 controller flashes as long as the charging cable is connected to the PS3, if I have removed the charging cable, the controller is dead, it does not work, have already tried several times to reset, as I said USB cable when charging everything flashes anyway no function can do so not use the console if I pulled the cable is not working at all, the controller was charged at least four 5 hours and only when charging turn signals controller otherwise no function

Then I would say battery is flat.

Provided the reset was done correctly

Buy a new bluetooth controller.
