X250 AC adapter port not working properly

I have the strangest problem with the AC port on my x250.  When the computer is docked, the gauge shows that the unit is plugged in and charging the battery.  When the 45W AC adapter is plugged directly into the computer, the battery charges when the computer is in sleep mode, but NOT when the lid is open and the computer is running.  This is a problem whenever I need to use the computer out of my office.

 

I have tried the following, all of which produce the same results:

 

-Tested with an alternate 45 AC adapter

-Uninstalled and reinstalled AC Adapter driver in Device Manager

-Removed and reinstalled the external battery

 

My hypothesis is that there is a hardware problem with the AC adapter port, but wanted to check to see if anyone had any other thoughts or suggestions before I take it in for a warranty repair.

 

Thanks.

Re: X250 AC adapter port not working properly

Shortly after I posted this problem, it fixed itself without my intervention.  Now, it is occuring regularly again.  Anyone else experience this?
