I own a Toshiba L455D satellite laptop. The fan doesn't stumble upon now and then, other than occasionally it does come on. I'd like to dirt free the heat sink as well as the fan itself. Therefore first I want to untie the laptop, except following removing each screw lying on the back, it at rest looks like stuck mutually. Is there various tricks to this? Do I must get rid of the HDD otherwise the optical drive or else somewhat else? It appears opening the back must be ordinary practices bearing in mind you have to dirt free the built up dust sometimes. There must be directions someplace. I can simply utilize the laptop until it excess heats. I'm utilizing Speedfan 4.42 to maintain track of the heat.
