Note that most batteries these days in anything more complex than a watch have "smart" charge controllers and so upower or similar can read what their design watt-hours and current maximum capacity are. Also, often the total charge or discharge rate. That plus a little math should tell you if it's an aging battery or if your machine is simply failing to idle down for some reason.

My Thinkpad is 6¼ years old and the batteries it shipped with are at 72 and 75 % of their original capacity. But I didn’t use them *that* much, and always kept them betweet 40 and 80 % charge when I didn’t need them, which is probably 98 % of the year. > 1 year is pretty short but possibly he might buy a new battery as a > test. They generally aren't overly expensive. I don’t believe that they went down to 25 % of their original capacity within a year. To achieve that, they must have endured unspeakable abuse. -- Grüße | Greetings | Salut | Qapla’ Please do not share anything from, with or about me on any social network.
