I am facing a weird problem with the Toshiba laptop which I am using. I have a Toshiba Satellite T115 laptop which is installed with Windows Vista operating system. The laptop was working fine till I updated the BIOS on the laptop. Now after upgrading the BIOS on Toshiba T115, the FAN keeps running constantly. I am not sure what is causing such problem and hence need your help. So if anybody has a solution for this problem then please suggest some. Thanks in advance.
