Having an identical issue with DELL Precision M6400.
Normal operation on battery and degraded performance on AC, CPU usage on 100 % even Task Manager running on 60 % usage. re-installed the OS and Installed/uninstalled the dell power management utility ( latest drivers,BIOS A09 ect), did not help.
Got DELL to swap out the mother board and graphics card, no changes ( even tried another adaptor from an identical machine).
does the converter board reside on the motherboard or is it a separate componet that can be replaced?

Uninstall any energy management software provided by dell and then check.if the issue is not resolved then the issue is with the converter board as it is heating up.
