Hi, When I boot my ThinkPad into Windows, I can set the battery to operate in long-life mode. It then only charges up to 90% capacity, and won't start charging until it has dropped below 80% capacity.
This is claimed to make the battery live longer -- and so far the battery HAS lasted much better than they have in previous laptops.
(Of course, if I'm going to a conference, I can configure the battery to charge up to 100% again easily)
I wondered if there is any way to achieve this behaviour in Linux?
There seems to have been some confusion regarding my post, above. It's my fault for not being clearer. I was talking about maintaining a battery which keeps its ability to hold a full charge. ie. By only charging the battery to ~90%, you can discharge/recharge it many more times, and still get close to the original life out of it, rather than if you charged it to 100% every time. With other laptops, I've noticed that after a year or two of use, they become nearly useless on battery. This Lenovo is doing really well after a couple, and I am assuming it's from the above behaviour. (But could be wrong.. maybe battery tech suddenly became much better? I doubt it.) -T
