HP 6735s Fan & heat problem.

[Cerebella]

Hi there,

I have had a 6735s laptop for about 4 months now, and since day one I have had a problem with the fan. 

When using my laptop for games or full screen films, the fan runs full power, which is understandable But when I am just browsing the internet, playing music or even have only just turned it on, the fan runs at full power, sounding like a vacuum cleaner and subsequentially ruins the battery life when I do not have the power cable plugged in.

Does anyone else have this problem? Using Everest, I have found that the CPU has hit 70 degrees C when just playing music using iTunes, 80 from start up and up to 95 degrees C when playing a game. This has become increasingly worrying, becuase of possible burn accidents, or damaging furniture when placing such a hot laptop on it.

I have also had the problem of almost shorting out my entire house when I plug in the power cable. I understand this may be an issue with the electrics here, but I'm pretty sure all the lights shouldn't go off & on when I plug in my laptop to charge.

Thanks in advance for any answers.

Ooops Same problem here . Every day like a pre-set time frame the laptop Fans starts making huge noise and it starts getting Hot.Some times the noise is quite unbarable almost like a Server making noise. When u open multiple applications which uses more memory (somestimes even multiple Word and Excel Sheets) the laptop behaves as though it is ment for generating Heat in Ice Cap regions.

Its like a routine for my laptop and its no more a laptop iam afraid it would burn my Skin some day ..

I think HP should recall these model... its not so safe.

here is a link to a doc that has a lot of tips on the issue you're talking about.

It's got links to lots of different things.

I also use Chillpads, and make my family do the same, make sure you use them on a hard surface too or the in-take vents can get clogged.

Good luck.

Well, I bought the 6735s laptop last november and I also noticed that it was a rather noisy laptop with a very temperimental DVD/CD player.

I am even more surprised because I am used to HP Compaq as I used to have a Presario R3000 ( and the processor was an AMD as well) and everything was ok.

I have never used my laptop on a bed but always on a clean desk and made sure the aeration was correct.

I have also used different OS, XP,Vista, Windows 7 and updated the bios but the heat and noise remained extreme.

I've sent it back to HP so they can fix these issues.

I'll keep you informed.

My 6735s is basically a kettle that can watch movies, play music and surf the internet. My CPU is, as we speak, running at 97'C!!! Does anybody know if HP would take this model back (im still in warranty) and swap it for a model with the same(ish) spec that doesnt leave you needing leg grafts???

I have contacted support and their suggestion was to use my recovery option and flash the bios. No im no expert, but neither of those option seemed to me to be able to sort this problem. A machine with this kind of spec would need to be cool but i think HP overlooked that when constructing this model. When its cool (usually for about 3-4mins after start up) this machine is pretty good, but use it for an hour of so and feel both your legs and left hand start to cook!!

I have sent back my HP 6735S to HP. The customer service agent was quite good and sent me the UPS box in time. My laptop was fixed and since then my laptop is very silent and doesn't reach such extreme temperature.

They flashed the bios and changed  the optical drive.

I recommand to use your warranty to get it fixed by HP.

Thats reassuring. I actually do love the machine but cant use it as it should be used. Did they inform you of what the problem was??? I am just sceptical as to whether the fix is a permanent one or a quick fix that will rear its ugly head 6 months down the line, when i am out of warranty!

Mine has had the same problem too, and just tonight when I turned mine on, the mousepad has completely died!!!!

Its not a windows driver problem as it displays the 'no mouse detected' even before it starts to boot into windows, so it looks like the heat might have caused it to die which is a complete gutter because as per usual my laptops out of the warrenty

Not impressed the way when not doing a lot the fan suddenly kicks in at full pelt especially when the Mrs is trying to watch the TV.

I have same problem before.HP 6735s AMD Athon QL 60 1,9

You just need to clear your laptop.Search over internet how to open your laptop.Also you can undervolt it.Search for K10STAT and read.I make my to work on 950Mhz@0,975v and 1,9Ghz@1.025v and temps are almost normal.Play Dirt 2 without problem and temp is no more 85.

It is really easy to fix. Hp give the solution on their website:

1. Buy an air duster (should cost about £3):

2. Switch your latop off (VERY IMPORTANT)

3. Place the nozzle of the air duster next to the vents on the left side of the laptop (do NOT turn the air duster upside down or on its side as you will spray liquid air).

4. Spray the air duster through each vent hole individually pointing to the left and to the right. (make sure your laptop is off)

5. Underneath your laptop there are the cool air vents repeat step 4. for them as well (make sure your laptop is off)

Before I did this my laptop was running at 85C in power saver and reaching 92C at high performance. Now it runs at 55C in power saver and 65C in high performance and the fan is almost inaudible.

If you want a completely silent fan then you need to send it back to hp to have the fan cleaned or if you know what you are doing then do it yourself. Here is the step by step guide:
