DV9000 / AMD - Experience after mainboard exchange ?

Hi, all

i am writing to you from germany...

i stumbled across this forum after my research for the meanwhile famous "heat problem" of the AMD based dv9000 laptops.

My dv9345 (AMD turion TL-56) purchased in september 2007 also produced quite a lot of heat - even in idle mode of the processor - and the fan went on every few minutes producing a lot of noise.

As i understood after having read a lot regarding this topic, HP indirectly acknowledges this "hardware problem" by offering the "warranty service enhancement" as described in
http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c01115890&cc=de&lc=de&dlc=de&dlc=de&lang=de

I updated the BIOS to the F.3D version but now the fan is running all the time, which is driving me mad because it is noisy. I would tolerate having the fan running but only at much lower RPM. I know that this is possible from a DELL i use in business. It seems that the whole design of the dv9000 is very poor in that respect.

I would be very interested in somebody´s experience of a mainboard exchange with an AMD based laptop. My main goal is to have a QUIET laptop when there is only a low CPU usage.
At the moment i am uncertain of daring to send the laptop to HP for repair if the noise persists.

thank you for every opinion on this and don´t hesitate to aks in case i didn´t manage to express myself.

regards, Harald

 

Im assuming what you want to know is if the new motherboards have a different and better design, which will allow the fan to cycle on and off as supposed to, and not stay on all the time.
So lets say your computer is dead, therefore you send it in for the replacement program. What do you get? They replace the motherboard which is the same like you have now (but new) and has the latest bios - which would clearly be running the fan all the time for future protection...

I doubt HP changed anything in design, as from what I understand written here http://h10025.www1.hp.com/ewfrf/wc/...s&dlc=en&docname=c01087277#c01087277_identify , the replacement program is for machines which ALREADY have the problems, as in the provided symptom list and if it doesnt, then go ahead and update the bios hoping your existing motherboard will last long (enough).

What does it legally mean? Like you correctly identified by saying "HP indirectly acknowledges" the problem, it means that HP recognized a class action lawsuit coming up requiring them to replace tens of thousands of machines if they dont do anything about it. So CEO, CTO and CFO sit together with Legal Services and set up the program called "HP Limited warranty service enhancement" to shut up those who already have the problem, vaccinate those who dont show symptoms yet, and handsome MARKETING executive hopes we all move to the next fashionable technology object before trouble comes...

 

Hi booyoo, hi all !

correct. In an ideal world, the producer of a part with a design flaw corrects it and offers replacement to the customer to finally satisfy him..

uh,oh... i fear your assumption is correct. Now i am in the sad position that i own a product which potentially gets broken. If i am "lucky", it happens within the extended 24 month warranty period.

As sad as concise put. If i don´t hear from anybody confirming that the replacement part doesn´t remedy both the heat AND the subsequent (fan) noise i´ll keep the machine here as it is.
My conclusion after all is to keep an eye on the noise emissions on future notebook purchases and pay special attention when there is a "bargain". There is a saying in german: "i am way too poor to buy cheap things"

BTW: in the moment my only relief is a mat of felt underneath the laptop. It damps the noise a little bit.

i have to correct myself: i will not let HP "repair" the part unless the replacement DOES correct the heat problem.

sorry.

 

Now that you've updated to the latest BIOS, wouldn't it already took care of the heat issue?

 

Yes. The heat is no problem (anymore) with the latest BIOS.
But: now the fan is always on. And this is very, very annoying because the fan rotates not silently as i am used to with other laptops. ( no, the fan wheel is not obstructed. I guess it´s just the cheap quality of the fan itself. )

Under "repair" i would expext - like indicated above - a changed design of the mainboard/software/BIOS/whatever combination that does not make it necessary that the fan blows when the notebook components are under no stress ( idle )

My fans goes off and on when the heat arises. It completely shuts off like nothing, then it comes back on when it reaches about 55c-56c. I like the fact that it's quiet; perhaps the purpose was to increase battery life, not that it matters anymore since my battery's not holding a charge for more than 20 minutes anyways, but I just didn't like the intermittence of it turning on from a quiet state.

Regarding my notebook; before upgrading to the new BIOS, my fans were always quietly running on the background as soon as I power the unit on, then the fan increases as the heat rises. Tell you the truth, I'd rather have the fans steadily 'on' at all times then having it 'off' most times.

 

I sent mine in after it 'broke' (beeeep beep beep) the first time and they replaced the motherboard / videocard. Different motherboard on it. After this it did not run as hot as before.

Well it failed again - TWICE. Had to keep sending it in for the same damn problem. Seems like HP is not interested in investing money into a real fix, just enough of a fix so that you run out of warranty and go away.

 

Same problem here I am in US and they replace motherboard, cooling fan, display and am now having keyboard problem as are many other hp customers who did the same. check out link it http://en.wikipedia.org/wiki/Dv9000z

 

tell them you want an intel, since amd's are having issues...i would try that. amd's have long had the over heating problem since the start. and in 2008, it doesn't seem to be leaving. and i use to be an amd fan, but overheating pushed me to the intels (1998)

 

The Intel models are having the same problem, just less often. Ironically if the AMD CPUs ran hotter and hit the 55C level that tripped the fan more often there would be fewer failures with the older BIOSes. The NVIDIA chipset and Broadcom WiFi cards do have higher thermal failure rates than their Intel equivalents, especially those Broadcom cards. Hopefully HP will bring out Puma platform notebooks with AMD chipsets and Atheros WiFi, which would bring failure rates in line with Intel's.

But the main problem is that HP's cooling system is simply inadequate for a notebook this big. Keeping the fan running slow and quiet provides just enough airflow to keep the rest of the notebook (away from the CPU) from cooking. If your fan is loud the problem is with your fan. The fan on my dv9000z is quiet. Whether it's worth dealing with HP support to get a replacement fan is up to you but I wouldn't risk it.
