I have a Thinkpad T440 with Ubuntu 14.04 (using i3wm). I have had trouble installing tp_smapi. I successfully installed it with dpkg -- can't remember whether I used apt or just downloaded it somewhere -- but I can't load the module.

When I use modprobe on tp_smapi, I get this:

"modprobe: ERROR: could not insert 'tp_smapi': No such device or address"

Note that this is different from the error I get when I mistype the module name.

I read somewhere that I might have to rebuild my kernel for it to work, but I'd thought that the kernel I was using (3.13.0-24) had that already set up.

Has anyone gotten it to work? I hate how Lenovo manages the batteries!
