Sweet, Ian! Which version of FreeBSD are you running? 8-STABLE is on
my X200 for now; have been thinking (for a while) to update to
10-STABLE.

No, I have not used any power related things in FreeBSD itself. I do
have BIOS setup to maximum performance when connected to AC power;
optimize battery otherwise. One thing I am not sure is what happens
when booted up on battery & some time later connect to AC, and vice
versa.

In any case I will try powered, and possibly other things.

Good to hear. Would that be suspend-to-RAM?

Oh, I remembered later somebody was running FreeBSD 11 on Macbook
Pro 2011 ...

Sure. (I am also looking for another one, this time much lighter
than X200. Is Thinkpad X1 Carbon II any lighter, I wonder.)

Well, somebody had reported success|progress with Intel i915 on
11-CURRENT (and somebody else had working suspend-resume with
"recent HEAD" on X230) ...
