Re: Access fan to clean it in my laptop
Everything is screwed into the back on a laptop. You must remove the top which is called the palmrest to get inside. Usually you would remove all the screws from the bottom of the notebook. Then remove the cover usually just above the keyboard and the keyboard itself. Then the screen needs to come off, usually a few more screws. Then a few more screws from the palmrest and it should come off. Then you will be at the motherboard and your should see the fans. I don't recomment doing all this though. Usually a few sprays from an air duster can into the exhaust vents will get the dust out of your fans without taking the machine apart.

this problem is probably due to fan being clogged with dust, a simple solution is to get compressed air can and spray out all the air ports on the side and under the laptop, if that does not work it will need and internal clean with new thermal compound for the cpu
HI there, this sounds like an overheating issue, look on the base of the machine for access panels, remove these and look for your fan. Chances are that it will be quite dusty. Clean this to the best of your ability and also remove the fan to clear the gap between it and the heatsink (a lot build up here) Put it back together and try again.
sound like you have an overheating issue, try removing the access panels on the base of the machine (unplug from the power first) and look for your fan, quite possibly there will be a fair amount of dust surrounding the fan blades, clean these to the best of your ability, and the remove the fan and check where it blows through the heatsink. This is an area which is prone to dust build up. Clear this area, refit the fan and access panels and try starting the machine.
Have a look around the base of the laptop for access panels, if you remove these, one of them should give you access to the fan, this fan blows air through a heatsink in order to cool the laptop down, clean all around the fan and also remove the fan to clear the gap in between the fan and the heatsink as dust builds up there very easily.
You didn't mention what make and model laptop you have but here is a general solution. Laptop overheating issues almost always involve fan blockage, or a bad (non-functional) fan. Some are easier to access than others. Look at your laptop and see if you have access from the bottom. You could possibly even access by removing the keyboard. IF you can access the fan you should clean out any lint or dust that is causing blockage of airflow (some dis-assembly may be required). KEEP IN MIND that if you remove the fan heatsink assembly you will need to re-apply thermal paste or compound to the area between the CPU and heatsink.
My guess is you will find that you have a strip of lint blocking the airflow between the exhaust of the fan and the heatsink fins.
Instead of opening the machine up to get to the fan, grill and air vents you are better of buying a can of compressed air and doing short blasts throught the air vents located at the sides or at the back of the laptop. Also turn the laptop upside down and find the fan grill and give a coulple of short blasts through that to clear any dust which has stuck to the fan blades.
I had to figure this out not long ago.
First you need to pry up the piece of plastic trim that covers the speakers at the top of the keyboard.
Next romove the screws that hold in the keyboard. they will all be along the top of the keyboard.
Once that is out of the way. Remove the screws that secure the metal sheild plate and remove the plate.
You can now see the two fans. If you follow the air ducting from the fans there will be some peices of a tape like material that once pulled back will give you access to the airway to the cooling fins. This is were you will use compressed air to blow out dust build up.
It is also a good idea to clean the fan blades.
Once this done, replace the tape covers and reassemble.
I hope this helps because I couldnt find any info on this on the web.
If it's overheating it's possible that either there's a problem with the fan, or the fan/heatsink is clogged with dust. If you know how to open up the laptop you can do that and use a can of compressed air to clean it out which may solve the problem. If not you'll have to replace the fan.
