Lenovo Ideapad Z565 – Resolving sudden shutdowns

Recently my Lenovo Ideapad Z565 laptop shut down suddenly without any prior warning under heavy computational load. Having some experience with the interior of my laptop due to prior problems with the fan making more noise than expected, it turned out that the heat fins at the fan’s air outlet accumulated too much dust again to properly cool down the laptop.

Opening the laptop’s back cover and cleaning the fan’s outlet as described in this earlier post resolved all issues. The laptop is now running stable again, even with all three cores running at 100% for a long time.
