I am having problems with my MBP's battery. I keep it plugged in unless I am not at my desk. It has been plugged in for the last 24 hours. I was working on it with it plugged in. After getting it to come on, I noticed that the battery was dead. It started charging back up, so I though nothing of it. I just looked at it and it is not at 3%. I do not see what the problem is. I am not doing that much on it. I am converting a file with VisualHub and looking at a PDF. Any ideas?
