I run a T600 (upgraded form a T520), which is the follow-on from the T500.
yes, it is possible to disable a cpu from within the SP (service processor).
You'd need to control-B (from the console) into the SP and navigate
the screens to see if any of your cpu/memory boards are
disabled.
Let me know if you need more help.
