Hi,
I don’t know about that specific model but the older Thinkpads (especially ex business) are a great way to go. I’m using a Thinkpad x220 with FreeBSD and all the hardware seems to work out of the box (intel video, sound, headphones, WiFi in particular). The only thing that doesn’t work is suspend/hibernate but I understand from this forum that that is common to FreeBSD on all laptops.
