my laptop recently overheated and turned off.Repaeated attempts to restart it failed and ended up with blue screen.Hours later it restgarted and worked OK for some time before again overheating.The fan was no longer working...I could make it out from the sound.
Service centre guys cleaned the cooling system and said main cause was dust in the system and suggested cooling pad as option.


Is there any alternative??
And what important points should be kept in mind while purchasing pad ?


Thanks.

cooling pads are ok but not necessary in my opinion ,just buy a can of compressed air and keep the fan and heatsinc cleaned off .works for us here with 3 laptops

Dont know if I have the right to restart an old post....but still

Laptop fan works well and at full speed during pre boot system assessment but after that during normal operation it doesnt work at all or spins at very low speed causing laptop to really heat up..There arent any error messagesor blue screen though.....pre boot tests show PASS

Can anyone help me where problem could lie ??


Thanks
Jose

Hello, it is certainly okay to revive an old post of yours if you so choose to do so.

You may want to have this cooling fan replaced, it is more than likely worn out and there is a possibility that the barrings are worn out causing the fan to bind up during rotation.

Now I want to add, there are situations where the fan speed may be controlled by the system, in a case like this, if the temperature detected by the sensor is below a threshold, the system will decrease the fan speed accordingly.

But it is very rare for the fan to stop or turn off altogether.

Using a temperature monitoring program will give you a basic idea of what temperatures the sensors are receiving and sending to the motherboard controller chip.

But of course it all depends on whether the laptop is capable of booting into windows long enough to get any readings.

You can use either speed fan or HWMonitor to help you analyze the current temperatures on your various senors.

Here are the links.

Speed Fan http://www.almico.com/sfdownload.php

HWMonitor http://www.cpuid.com/hwmonitor.php

If your laptop can not run long enough to run either program listed above, I strongly suggest you replace this cooling fan, or double check that it is not being held back from spinning due to dust built up in the heat sink.

Bruce.

A replacement fan would mean taking apart the laptop which can be very tricky sometimes.

Yes, it's ok, but maybe under some of the components there are still dust. I've experienced it few times when the dust collects under the processor, so u can't see it, but problem is still there. Superficially cleaning doesn't do the work always. Sometimes the deep cleaning is needed! And of course if it is possible thermal paste should be considered!

With regards,

Joshua

Thanks everyone for inputs :)

@ MrBruce1959
Is it safe to use those software ?I mean the software will only analyze and not try to control speed ?

@all
please provide any relaiable online sources providing instruction about cleaning laptop ..



Thanks again

To effectively clean a laptop you would have to disassemble it. But you said the service centre guys has already cleaned it out, did they taken it apart and cleaned it? Can you please provide the model of this laptop?

I had a laptop that was overheating due to the fan not spinning after windows had loaded, seemed like the fan controller was faulty so I ended up cutting one of the wires running to the fan but I can't remember the specifics, this made the fan run continuously and it worked perfectly for the remainder of its life. Just my 2 cents on a situation that might be unique to the laptop I had, but worth looking into if you're confident in doing so.

So what is the model of your laptop? At the moment i would have to agree with the others about the fan.
