Alienware 15 R2 New AC Adapter will not charge laptop

I recently bought a new Adapter since I broke the plug on the original one. I had chatted with a Dell tech support person and they recommended this adapter. However when I got it, and plugged the new adapter in, it's saying that it's plugged in and not charging. Also when I reboot my system, I get a message on start up that I'm using an unknown adapter. Is it still the wrong adapter even tho it clearly says it will work for my system?

The problem may not have been the adapter - but rather the DC in jack.  That would be the next thing to try.

The thing is, I can still jury rig my original adapter to charge, and it works fine.

That should not be necessary - it sounds like a bad DC jack, since two adapters do not work correctly.

Hi @Dan.D.,

If you already replaced the AC and the DC Jack, then looks like a motherboard issue.

Last step, make sure the BIOS is up to date.
