Hi Guys, I have TOSHIBA Settelite A45 S151 and i am getting this warning "A problem with the cooling system has been detected." My machine becomes very slow. I check some theads to find out whats going on. Most of them says it may be heat sink or fan. But my fan is working and I cleaned my heat sink properly but still it is giving me the same problem. Does anyone know what could be the problem?
