The wattage and type of the AC adapter cannot be determined
I am getting this error message. My battery is not charging. And it is clocking my cpu speed to 0.5 GHz. I heard that there is a pin in the DC jack that tells a chip on the computer to tell the computer that the AC adapter is not suitable (whether damage or low wattage). I'm wondering if there is a way to disable the chip and just use it at full speed, I don't really need a battery because I'm mainly on AC use anyways.

Mine will do that if the plug is not all the way in. It has happened to me twice now and I would have thought it would take more than 1/16th of an inch to cause the situation.
Sorry I don't know of a way to bypass this check.

There is no bypass (you can turn off the message but the system will then run as if on battery all the time).
First try: a new Dell OEM AC adapter. If that doesn't solve the problem, and your system uses a removeable DC jack (most newer ones do), replace the DC jack. If your system has a soldered-on jack, you can either have a shop replace the jack or replace the mainboard.
