broken record: just bought a t530 and the prtsc key makes me crazy. Who thought this was a good idea?? That and switching the left ctrl & fn (so it's like a mac). I suppose these things are just not for programmers/power users; anyway it's a big PITA to switch from ctrl under shift bottom left (every other PC keyboard) to "ctrl somewhere else, you just dimmed the screen."

EDIT: Thank you for BIOS keyswap tip. It's still not as good as a properly placed, properly sized ctrl key but this helps!
