I have a Toshiba Tablet laptop with Windows XP on it. I have problems with its cord port. It seems that the shaft in the port is either loose or has moved too far back. Because I have to keep my laptop in such positions that it won't be disconnected with any move. If it does, my laptop screen cannot stay bright and on, then in less than 5 minutes it will be off. Its battery life does not work, this is why I have to keep it plugged in (into the power) at all times. I wonder how can I fix its port problem?
