My sisters manufacturer warranty on her asus eee pad transformer tf101 tablet is over so she wants me to try and fix it for her. She is having problems with the battery. It said the battery was 0% and the battery icon had a red exclamation mark. I plugged it in but the battery indicator still said discharging, battery health: dead. First I tried replacing the battery. Now when I plug it in the battery indicator says discharging, battery health: good. So the tablet still was not recognizing that it was plugged in. So then I tried replacing the charging/data cable. Now it seems to recognize when it is plugged in but the battery still says that it is not charging. Do you think it could be the charging port or could it be a software problem. It won't let me do any software updates because the battery is very low.
