E5540 battery not charging when computer is off

Battery is in good health and support assist run regularly with not problems.  However when the computer is off and plugged in the battery does not charge.  When turned on then the charging starts.  I have one battery.  I checked in device managers and saw 2 items listed Microsoft ACPI-Compliant Control Method Battery.  They both seem to have the same specs except that under properties events one has a 2 attached to it in the information section and the other has a 1.  I don't know if this means one applies to battery 1 and the other to battery 2.  In checking on the web I saw a response to the same problem

I do not know if this can be done on the E5540 and if it can, can it be used on just the one Microsoft ACPI-Compliant Control Method Battery or on both?  Basically it says should uninstall and reinstall

 

Thanks for any help that can be given.
