We have an old serial port device that will not communicate with it's software properly on an Optiplex 790/7010 running Windows 7 (Enterprise x64). On a Optiplex 755 running Windows 7 (enterprise x64) it works fine.
When my laptop is turned on watching a video and I start charging it, it will most likely say "plugged in, not charging" and give me a message about getting a Dell 45W charger (I am using the official charger that came with the laptop).
