I doubt that a new charger will fix your problem. Most often it is a connection on your motherboard or a peice of quipement that is attatched to your motherboard that is failing. That is why bending it funny somtimes works, as the connection is re-established. Either way, you're most likely looking at replacing the power plug in on the computer(which is usually attatched to the motherboard on a laptop, so you're looking at a new motherboard) or replacing the computer all together.
