Windows 10: AC Adapter Won't Charge, BIOS Error

I have an Alienware R3 laptop, and I use a standard 240W adapter with it. Recently, my laptop has stopped charging completely when it is plugged in. When I boot it up, I get a message saying "unable to determine the power and type of adapter," but when I run the diagnostics tool it comes up with, it says that the adapter is using 255W. How can I troubleshoot this?

I uninstalled Microsoft AC Adapter Driver by accident, PC won't start.


Thank you, gave it a try following your tips but no change, still does not power up.

My power source never had a loose contact problem before. Really, all these problems started after deleting the AC adapter.

Any other suggestions?
