I didn’t know the X220 series was affected, the problem reports I heard
all mention the recent Haswell generation. Is that a typo and you meant
to write X240? Or is the X220 affected by the same problem, or are there
seperate problems? All BIOS brick problems I could find seem to be
related to BIOS upgrades, although the symptoms you describe do sound
like the ones we heard from the Haswell generation laptops.

Good to know the repair is hassle-free.
