I have a Toshiba Satellite l305-s5899. It hasn't done an emergency shutdown from excess heat (yet), but I really do not want it to get to that point. This thing is my main computer. Anyhow, im pretty sure its getting hot because of dust, but heres the catch. Im pretty savvy with taking apart desktop computers, but not laptops. Id like to clean this thing out as soon as possible, im just afraid to screw something up by just jumping in, taking out screws and such. I need to get to the fan and heatsink. Could anyone tell me if it would be too risky? Am i gonna have to take out alot of parts to get to the fan and heatsink?
