I get this error message when I power the 9300 with AC Power:

The AC power adapter 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

I check the AC adapter and it is 90W. Do I have a faulty AC adapter? I am about to call Dell Support.

**update**

I talked to Dell support. He said that this is a known issue with some of the 9300 laptops and they will ship me a new AC adapter. BTW, I am glad I bought this thru small biz section. Initially I accidentally when to Dell Home support and was starting to go thru voice menu hell. I went to small biz section and talked to a Dell rep from U$ pretty quickly
