RE: Laptop (Precision 1350 Workstation) Plugged in not Charging after using it with dell docking station (dell e port plus usb 3.0 replicatior)
I'm starting to have the same issue as you,with a dell E-port Plus docking station with my Latitude E5440. At boot I get a message saying insufficient power and I have to manually run diagnostics each time to re-establish that i do indeed have the correct amount of power. In addition to this if running a high stress software or game (photoshop) I will notice that my battery will stop receiving power (plugged in, not charging) and performance will drop like a rock and start running hot.
The only "fix" to this I have found is to plug in your laptops powers supply as well to supplement its power needs.
