Hey all, 

Here's a great guide by Daniel_Potyrala on Preventing and Dealing with Overheating. 

Also another link to a guide on Keeping Your Notebook Cool. 

Please let me know if you have any questions 🙂

I had the same diffulty - mahine switching itself off after only about an hour's worth of low usage (youtube and emails).  The report on switching it back on always said that forced switch off was due to temperature being too high at 90. 

My fix was simply to turn it on its back and use a very powerful Dyson vacume cleaner over the fan area - then used a pin to help the dust get through to the outside - alot came through and now all fixed.

@Tonycf Thanks for sharing! That is actually a great idea. It's much better to suck the dust out of the computer rather than using canned air from outside the computer to blow it further into the computer.

For anyone wanting to clean their computer but doesn't want to open it up or doesn't feel comfortable opening it up, this is the best alternative. You could use a pin, toothbrush or clean paint brush with any vacuum cleaner (the more powerful, the better).

AFTER

I have a i5 and it lastest 1 year before the heat caused the harddrive to fail and the fan to stop spinning.  I kept it clean and maintained.  I replaced the harddrive and fane (huge undertaking since the whole notebook has to come apart to get to fan) and here I am a year later the fan blowing all the time again.

I will NEVER by HP again...EVER!  Granted these notebooks are made by some chinese or tiawan based OEM but HP has to pay the price.  I bought two Asus notebooks running i7 and for my daughters and they are cool, quiet and out perform this HP media PC without even breaking a sweat.

I should put this thing on Ebay for it takes a crap again and costs me another $100 and hours of labor.

i have all the same problems to my hp pavilion dv7 4100 series. I have got an intel i5 and AMD radeon 5400series with will get very hot! however i purhased some air can (with HP said i needed to) and the only thing it did was helping me to put the temp down by ehm lets say 10 degree C. The thing it didnt do was helping me from "THE" Noise (or better said yet engine). i now bought a notebook stand from CM, with does the job a bit... highest temps are aound 80C now. now im searching and thinking to replace the fan of the laptop(with is a mothr*** puece of sh**). but i cant find them and dont know with one of them is ok to put in the of someone can help me please. i would apprieciate that 😄 . And for hp where are youre answers and solvings for this problems???

Temporary solution

Vacuumclean the air passages. Lift the laptop 1 to 2 cm above the table and put something under each corner to get more airflow under the laptop. I did and the CPU temperature fell ca 10C+. Don't block the laptop's air passages.


Permanent solution, quote:

One other thing you may want to do, actually two things.

1. Just cleaning the fan the way you suggest may not get all th vent holes cleared out. It is better to take the lap top apart remove the motherboard and remove the fan along with the heat sinks. Next you will find 4 screws on the top side of the fan, remove them. This will seperate the fan from it's housing, now look at the vents from the inside, you may notice a lot of lint stuck squished agains the fan cover. Take a small brush or caned air to clean out. Then take a q-tip and some rubbing alcohol and clean each fan blade. this will take care of the fan problem.

2. I have noticed on most of these laptops that the heatsink compound is lacking to say the leaset. Clean the compound off of the processor and heat sinks. Clean with rubbing alcohol then apply a liberal amount of thermal past and re attach.

I did these two things and have not had any more problems with overheating. Below are two videos. The first will show you how to take apart your laptop. The second will show you how to remove the fan/heatsinks and apply the new thermal comound.

Hope this helps......
