I run Net on my t420, and I like it. I feel like I get ~3 hours (I don't keep hard time) using it, and it'd be fair to say typical use is development, w/ web (ie: running X, vi, clang, and various text-processing tools, Firefox, and disk/network intensive things like syncing code-repositories). I've got a 9-cell battery. I'm running -current. Now that -current is also offloading rendering to my integrated i915 gfx, I'll be curious to see how screen-intensive work will impact battery. The joy I get from NetBSD has outweighed various temptations from other OSes. I've dabbled w/ Ubuntu and others, but they're not compelling enough to switch. If you've got any questions, I'm happy to try to answer.

Your 9 cell is probably knackered. I get about 7 hours out of mine and its two years old.

  What OS/power-management are you running ?
  - cowabunga 12y ago
    FreeBSD 10 r10 stable with some ACPI frigs and dpms set up (I didn't write them down) Windows 8.1 Pro with Lenovo power manager installed via windows update. Dual boot.

      New battery en route --- I'll be able to tell first-hand what the differences are in a week or so :)

        Good for you :) I would check the Lenovo recall page (google it) before paying for one. That's where I got my new one from - they replaced it free of charge ;-)

>If you've got any questions, I'm happy to try to answer. I'm not really a leet haxor when it comes to fiddling with driver power management and configs. I like linux because I can just fire up powertop and manually switch the config settings to the ones that TLP doesn't flip automatically. Did you have to do a lot of hacking and do you know if openbsd is comparable in terms of power management?
