PS3 controller won't charge.

[castletonsnob]

I tried to play on my PS3, but my controller won't turn on, even though it's connected to the charger. What do I do?

I haven't had to deal with this yet but haven't used my remaining PS3 controller in about a decade. It's probably in a similar boat.

My guess is you'll have to find a service that is willing to replace the battery or find a way to buy the replacement and do it yourself.

Determining whether this is an issue with either the controller, the charging cable, or even the console's charging port is the first action needing to be taken.

If you already have an additional controller, try that out to see if the cable charges it. If that also isn't charging, clean the console's charging port in the event there's dust build-up. And if neither of those actions yield results, buying a new cable would be the last simple means to solve the problem.
