Genuine Dell battery charger not recognized

Dell Latitude xt2 tablet pc
March 25, 2010 at 11:39:03
Specs: Windows 7
My computer says that it doesn't recognize my
charger and that I need to switch to a Dell charger
(which I am already using). Nothing has changed
about my set-up the message just started coming up.

Could it be because I am using a 4-way plug (power
strip type device)?

The AC adapter must output the correct D.C. voltage and polarity (which of the pin hole and the outside shell are positive or negative on the plug). That probably varies depending on which Dell model you have.

If it IS the correct voltage and polarity.....

Laptop no video, and battery, AC adapter, power jack T shooting.
