    My laptop keeps overheating and shutting down on its own suddenly so I guess its t do with heat controller or needs new fan?

    However I doubt I cold even afford that

    I don't know where you are but it has been crazy hot in the US these last few days so if you are here, that is probably what it is. A new fan would help but you won't be able to work for hours and hours in this kind of heat anyway. Keep the laptop in a well ventilated spot: not on your lap. If you have a home fan, sit near it and let it blow on the laptop as much as possible.

    I had exactly the same problem. I solved it by taking the laptop to a service for some cleaning; the dust was clogging up and the processor was overheating.

    I was gonna suggest this. Dust seems to be the cause here rofl.
    You could try taking a vacuum cleaner and try to clean at the in/exit holes.

    I used to work at a major computer repair place. You can buy some compressed air and just blow it first in the out direction (usually bottom), then in (usually side or back) and then out again. That should clear out most dust.

    I don't use a cooling pad, I just try and keep my machine elevated by using anything as a wedge -- I just place it in the back and it elevate my laptop about an inch. It also tilts the keyboard towards me a bit and makes writing a bit more comfortable.

    If your laptop uses a regular hard drive instead of one of the new solid state drives be careful of compressed air. Going crash with the compressed air can force dust into the mechanical parts of the hard drive and cause read write corruptions and the bearings to go out.

    That said cleaning the dust will help cool if there is a bunch, but so will elevating it so air can pass underneath.

    Well, usually you don't even need to open it up. The dust only gets into the heatsink and fan assembly. Thus you need to only find the air intake and air exhaust, the intake should be on the bottom of you laptop and the exhaust should be either on the side or on the back. Just blow air into the intake and the exhaust and that should take care of like 95% of dust in there without having to open up the whole machine.

    I suggest doing this once at 6 months. :)

    As count_o said compressed air will address the dust if that was the culprit. The other possibility is that the fan died as well which requires a little courage to replace. I also elevate my laptops which run all day long on a wire stands to allow for proper air circulation.

    Some good advice about where to shoot the compressed air; thanks for that.

    I have 2 laptops going 24/7 and I have a Targus brand cooling stand under both of them.

    I also keep my office at about 74 degrees farenheit but I have never blown them out with compressed air. I'll put that on my Office Depot list and get that next week.

    Regular hard drives are air tight , you would not force dust in there with a can of air. Never turn the can upside down as the coolant can do damage.

    Blowing air in the vents is good, vacuuming the vents is okay. Never use a vacuum on an opened/exposed laptop or pc as you can get static damage from the tip.

    If its over heating but you found no dust on the fan or clogging the heatsink then either it is your fan or the environment. A heat sensor failing is extremely rare and if that is the problem then your likely to see other main-board damage.


    If its environment, then Try raising the laptop so air can get in underneath, four soda caps do a good job for that and point an external fan at it.

    If it is the fan then you do need to replace it as you will only end up damaging it . If your comfortable opening it up and take static precautions then replacing a fan is not that hard. You can get parts cheap on ebay

    I had fits trying to solve a similar issue.
    I ended up opening it and vacuuming out the dust bunnies AND as it was an old as Noah, I removed the fans and heat sink and re-applied Arctic Silver to the cpu and gpu.
    Fixed it.
    I did seem to have adequate air blowing from the fan, so I think re-applying the heat sink grease was the fix.
    I don't know for sure, I suspect the grease just dried out and didn't contact as well.
    Good luck

    Everybody pretty much covered it:

    1) blow out any possible dust
    2) put something under it on the far back to make sure its not flat on your surface so it can breathe and push air out the bottom

    There could be a few reasons why. Here is a few:

    Dust around the fan and heatsinks - Solution: Use a compressed air can and blow it away

    Your hard drive needs to be defragmented (Too much crap on your hard drive makes your PC work over time. More processes = More fan speed to counter the heat) - Solution: Use a program called Defraggler to Defrag your HDD and use CCleaner also.

    Last one if the obvious - You need a new computer or a set of fans (Try new fans first).

    I done 2 years work experience as a PC tech so hit me up if you need anything else.
