Alienware 17x R2 Charger doesn't work after BIOS A10 update

Hello everyone, 

i wanted to start by saying that i know the Alienware 17x R2 is a little outdated, but i want to find ways to fix it. So before, I my laptop was up and running really well. But after the Bios A10 update, the laptop would not charge any more. I used 3 chargers to try to see if maybe one of the chargers would work. 2 of the chargers are 240W Delta branded. And the other charger is Flextronics. Now theres currently no OS on the laptop. When I boot up the laptop the following message is displayed:
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 180W AC adapter or higher for best system operation"

Also, the motherboard and AC pin were replaced.

Any help would be appreciated!
