I regret I bought a HP notebook because of the bad cooling system

[webman01]

I regret I bought a HP notebook because of the bad cooling system and therefore overheating problems.

Yes you read it well. I have a HP-G42-362LA about 2 months now and I'am living in South-America where the temperatures are around 30 degrees Celsius. They sell notebooks here too But why?

HP have added after the type 362, LA which stands for Latin-America, so HP knows there is a heating problem here and it's not only the keyboard layout. People here wants a notebook too, but a working notebook.

Why selling notebooks in a country with that temperatures while HP knows THEY HAVE THE problems with bad cooling.

I should have know better and got another mark.

But now I  am stucked with it and want a solution from HP.

When calling them you call over all the world and pay for it.

Bringing back and claiming at the shop is not an option, because I will be missing the notebook for some weeks, whether it comes back is the question too.

Furthermore I installed a more advanced OS on it, because the standard windows 7 home basic spanish, is not able to address more than 3 GB. And my data is stored on the disc too.

So I was studying the problem  for the last days and came to some tips for others who encounters the same problem.

I have windows 7 ultimate 64bit english installed with a i3-M370, 4GB RAM and a 320 GB disk@7200rpm.

Running fast till it dies.

Idle temperatures are 75-80 degrees in a room with airconditioning, without 80-85 degrees Celsius.

I am using the notebook for development, internet and office. So my system demands are not that high and a i3 is enough.

When I am zipping or have some browseractivities the internal ventilator starts working at 80 degrees and temperature is climbing rapidly to 90 and the system dies in sleep and has a thermal shutdown.

It's impossible to work with. So that needs a fast solution.

Of course, like my old notebook I use a base with ventilator too, which is no luxury here, but a need.

That's for 5 degrees less.

I removed the RAM-door and noted the door had a closed plastic sticker, why? The hottest spot was closed !

- Who engineered this notebook forgot cooling, the greatest problem of notebooks. Not really smart. -

Removing it  got 2 degrees less. Manipulating the voltage is not possible so I went to the Power options in the configuration module of windows 7 and changed my powerplan.

Change power settings, High performance, Powerprocesmanagement, minimum 50%, maximum 80%, OK, save changes.

Downloaded Trottlestop 3.30 at http://www.techinferno.com/downloads/ and run it

Set clockmodulation at 75% and mark, chipset clock mod at 75% and mark, multiplier 1 less than the max. (e.g. 18 becomes 17) and mark, mark powersaver, mark EIST, mark BD PROCHOT, in TPL set TDP to 0 and TDC to 0 and OK, save and Turn On.

Start the utility anytime after the boot. 

Now I have an idle temperature of 55-60 degrees and a working temperature that loops to 88 degrees. SO I CAN'T DO HEAVY STUFF or the thermal shutdown activates again.

Tomorrow I buy another base with cooling and hope I can work better with another 5 degrees less.

Because of my settings I have lost power of the i3 processor and it likes a 1600 Mhz instead of a 2400 Mhz machine.

And the problem still remains.

In my opinion :

There must be a better cooling device inside the notebook and more coolingroom.

In the BIOS-setup the user must be able to downgrade the voltage within permitted range for that countries who has a warm climate. Now this is not possible.

In the BIOS-setup there must me more settings possible to adjust for the advanced user. It can be done with permitted ranges. Now this is not possible.

Hope some one has better ideas,but in any case I hope I could help some one till we have a more stable solution.

Well, I changed the base with ventilator and bought a Compaq base, elevating a bit from the desktop with a large ventilator.

It does make a little difference, but is not the solution. The doors from the harddisk and RAM must be removed to make cooling possible by the fan.

Therefore I decided to delete my win7ultimate64bit partition and installed win7ultimate32bit to see the difference.

The obvious difference was, I could not use my 4GB RAM and the temperature was equal.

I decided to delete this one too and installed win7professional64bit and that makes a better difference, I won 5 degrees Celsius less.

But when installing and certainly when the systemresources are in volved, the temperatures rises to thermal shutdown.

Great stuff, but NOT.

When I reclame at HP to switch the notebook for a new one, the problem does not leave.

The only solution I can think of to lower the voltage. So I am looking for how to undervolting the I3-M370 .

I searched the BIOS from insyde and have the latest F.37 installed.

Maybe someone has ideas about this.

I have the program R-W-everthing, but only use it to peek and not to poke.

Maybe one poke will be sufficient to solve this problem. Who knows where to poke?

And not only my notebook, because I know here in Colombia there are more who has this problem.

When only using for surfing and wordprocessing the problem not occurs, but the internal fan only runs constantly.

The notebook stand of Compaq did not work, all the heat collects in the plastic frame and no airflow was felt.

I have replaced the Compaq base with this one, a notebook cooling stand from Zipy and hereby the demands of a notebook standard that works for me, but after trying 6 different ones this is the winner, for now.

In case it is necessary I can replace the fans with more powerfull fans.

• It ' s metalic,
• has 2 fans at 1600 rpm,
• noise <19Dba,
• Airflow 20Cfm
• and at the back it's higher to permit the warm and cold air underneath the notebook to flow.

Furthermore I have set my powerplan to balanced and within the procesor power management the maximum processor state at 50% .

And now I am not all the time above the 80 degrees Celsius, between 60 and 80 degrees and still be able to use the notebook above 31 degrees celsius climate.

I cross my fingers and hope that after a week of no Thermal Shutdowns I solved my problem.

For the ones who wants this approach hereby an image of the Zipy.

No, I don't have a solution.

It's a combination of HP bad ventilation system and the use of windows 7 resources.

windows 7 uses resources standard which are not needed with all configurations, That causes power and therefore heat.

The HP is very critical with airflow and has a bad design to flow the air and cool the cpu.

With the base show in this thread it functions better, but even when the sun is not shining and the roomtemperature is 15 degree Celsius it automatically can overheat and shutdown.

So it's a problem when I am copying my internal hd to my extern to my external hd and that's whitout windows !

No it is true windows 7 consumes power not needed, but it is not the source of the problems , it the bad design of this and more notebooks.

I have now tuned all apllications I use with ashampoo coretuner 2 and in that whay I try to prevent overheating when it is the case of software. So I am not able to use the full power of this {Content Removed: Language Filter Evasion}
 machine.

Hello I am back,

Still don't have a solution but learn a lot about overheating and windows 7 tuning

But I finally think I found the problem.

When starting the G42 in BIOS and I stay it there with the blue BIOS screen, the fan starts working and working and finally it cant cool the system and shuts down.

So it can be a hardware problem. What did I change from day 1 ?

 I added 2 GB DDR3 same specs as the original 2 GB.

Without the new 2 GB same problems. So it was at the start when I bougth the G42 too a problem, but didn't notice it, because............. windows 7 took over control.

When running without windows 7 the cpu doesn't throttle and runs full speed.

With windows 7setting powermanagement maximum cpu at 80% or less it trottles till that amount.

2400 mHz  with 80% maxs 1920 mHz and 2400 mHz with 1200mHz.

So the cpu doesn't work that hard and is less fast hot. But in the end it gets hot.

It gets hot, when scanning the system, copying large files, backing up, multimedia, etc.

And it gets 90 degrees Celsius and shut down.

To control this I also stopped and disabled services not needed but started by default of microsoft.

No more background stuff running.

And stopped aero and now working like I am in XP style.

I also have uninstalled my virusscanner and use ONLY superantspyware 5 with realtime protection enabled.

And now I am at around 65 degrees running, but with care.

I even installed Pinguy OS on a separate partition, but the problem still exist.

When Installing Pinguy I had to do it 4 times, 4 times shutdown and with a ventilator directly at my notebook.

I could not find dust in the cooling corridor, can it be the cpu which is a problem or which other devices ?

When I return it to HP service, I want to change for another G42 working well. I have it since july 2011 so I have guarantee.

Do they change rightaway the notebook or do I have to wait weeks?

[webman01 · Accepted solution]

As promised I would tell the endresult.

I have brought my notebook to HP servicecenter and they repaired it and after 8 days I got it back.

HP replaced the fan. And of course the thermal pasta.........

And now up and running at 37 degrees Celsius and before the double near the thermal shutdown.

But I stressed my notebook now with all heavy work at 100% cpu power to know certain it's OK before my warranty expires over 5 months.

So don't be shy, as I did, but right away to HP with this problem. No more wasting time with reinstallations etc.

HP always thinks it's your fault by using the wrong drivers etc., but IT IS NOT.
