I am using Toshiba Satellite A305-S6905. It was working problem free till yesterday night. But when I started my Laptop today morning I was surprised to know that the battery icon in the system tray has disappeared. It has gone missing. I am unable to find the reason behind this problem. Does anyone know what must have caused this thing to happen? Do anyone have any solution to get rid of this problem. If anybody has any suggestion, then please help me. It will be appreciated. Thanks in advance.
