Dell Power Manager Lite

FOr the last few weeks... I get an error message every time I plug my charger in. Now I cannot charge my battery. sometime it works and other times not. May be related to what ever else is plugged into the house outlets at home... iPad, iPhone, Mac computers, HP printer, etc.

Very annoying and now cannot leave my puter unplugged.

I think it is a software issue as the charger and cord all work fine to keep the puter alive when plugged in.
