I bought an Asus laptop with windows 7 from Best Buy about a year ago, and recently a warning came up saying "There is a problem with your battery so your computer might shut down suddenly." The computer isn't that old, and reading some things and talking to people I at first thought that it might be a problem with the batteries memory, being that I didn't run the battery through a full cycle often. However, it's a Lithium ion battery, which aren't supposed to have this problem. I've searched and found topics over this saying that it's a problem with Windows 7, however most of these are over a year old and don't provide any relevant answers. I have a warranty so I can get a new one easily, but less than a year is very little time for a battery to last, especially when i didn't run it unplugged that often, and it only had an hour and a half battery life to begin with. This all happens even if the computer is plugged in, and even if i remove the battery altogether. It has been shutting down completely at random recently and it is extremely inconvenient to have this happen. It seems like it shouldn't happen when its plugged in or with the battery removed, so I'm at a lost to what the problem could be from.
