I've been using Ubuntu 13.10 on my Lenovo for more than 5 months without a problem. Yesterday I disconnected the AC adapter to take the laptop with me to the couch and it simply shut down. So I reconnected it to at least be able to check what was going on and, to my surprise, the OS seems to be recognizing the battery as it always did. This is the result of dumping upower:

Yet, I still can't use the battery... It's as if the OS knew the battery was there but couldn't switch to it whenever the AC adapter is disconnected. The battery icon, by the way, is always full.
