Short answer: I don't know
A couple of guesses: Fn+C. if that isn't it try bringing up the on-screen keyboard and toggling it there.

Yes, I tried the fn C and that too is a hit or miss. The scroll may work for a minute and then it shuts down again. One of many maladies on this computer.
I also get an error message every hour on the hour as a pop up window that says "message check has stopped working". I have over 20,000 messages somewhere in space, yet not a one will pull up. Have tried everything to get rid of this window messge, and yet still it persists. Just another added mess to this computer that I have owned for less than a yeatr.

Someone else had commented this, and the fn+K worked for me. Just thought I'd share. I'm on the T470S
The keyboard shortcuts for Pause, Break, SysRq and Scroll Lock on the E540 are as follow:
Fn+ B : Break
Fn+ K : Scroll Lock
Fn+ P : Pause
Fn+ S: SysRq
