It has recently come to my attention that my old Toshiba Satellite Pro 440CDX, that when it is on, gets very hot underneath. Now only every 2 hours or so my fan turns on, stays on for about half an hour and turns off. But, the system does nto cool down. So i am wondering how I can change my Laptop to keep its fan on all the time that the laptop is on? And not just every 2 hours.
