(HD) (CC) PLEASE READ! This "simple fix" video is intended especially for STUDENTS who are in a pinch and have very few tools or resources nearby, INCLUDING COMPRESSED AIR! This video shows how to revive almost any laptop that keeps turning itself off, or shuts off while it's being used due to an "overheating condition", without any special tools or taking anything apart. The fix shown in this video deals with a VERY common problem that so many laptops will have. The common cause of "overheating" is often a hidden dust build-up on the fan, heat sink, and/or internal parts!
IMPORTANT NOTE! There is always a possibility that the laptop fan could become "jammed-up" with the dust that is blown back from the processor heat sink while doing this cleaning procedure, so be warned! The odds are very slight, but they ARE there! If this situation occurs, I would (and have in the past) used a vacuum hose from something like a shop vac, or something similar to get the dust off the fan allowing it to spin free. Myself, I would power off the laptop, place the vacuum suction near the "fan inlet" vent to achieve this. The vacuum will dislodge the dust, and the fan will start to spin. DO NOT let the fan spin up at a fast rate of speed as damage to the fan could occur. I have cleaned many laptops, and by using the procedure described here and in this video, I have always had success. I have never had to take a laptop apart because of a dust build-up.
BTW, ANY laptop (AND PC) that moves air "into and out of itself" with a fan, will be susceptible to a dust build-up, eventually leading to an overheating condition.
Symptoms of laptop over-heating may include (but are not limited to)
• A very noisy or racing cooling fan with little air coming out from the laptop.
• If any air is coming out from the laptop, it is quite hot! (It should only be warm)
• No cooling fan sound, because the fan is stuck from dust build-up.
• The bottom of the laptop near the fan area getting very hot.
