Working around I've found the following Thinkpads have this issue & solution:
X200 X200s X200t
X300 X301
T400 T500
W500 W700 W700ds
Though I cannont figure out anything about the "SL" line of Thinkpads.
@jango You don't need to test it. I've verified it's the same problem & solution as all the other thinkpads
