In one frozen day of february 2010 I bought brand new laptop. It was Packard Bell LJ75 modification LJ75-JN-101RU based on, new for that time, Intel Core i3 processor and ATI Mobility Radeon HD 5400 GPU. The first think that struck me in new laptop — it’s almost not heated, in comparison with my old Samsung R40. Packard Bell stay cold even on two hour of HD filming on sofa. It was really cool! But as time passed, I began to notice that temperature of my laptop is growing. It’s time to disassembly and clean my laptop.
