So here's the deal, every time I plug in my adapter wire to charge my laptop I get this message.

"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation.

Sometimes it charges up but more than likely I get this message which is wrecking my head I'm at my wits end here, it's been happening ages now, very frustrating, I've tried a few little things I've read online but none of them work. It's not my adapter as I've tried a few different ones and same thing happens. I've tried disabling QuickSet to. Any ideas
