Not doable unless you have the original electrical engineering schematics of the motherboard, a sottering iron, an undertanding of electrical current, capacitors, resistors, and the work... or an electrical engineering degree with training on this specific montherboard will do, and then you'de have to have an osilascope to test your signal levels.. so in short no can do...
I've got some more research information I've compiled through visiting the forums on this issue... my research follows::::
I've formatted my entry for ease of research and reading:
HP DELETES ENTRIES ON FORUM:
***HP has deleted or is censoring my entry. I will keep posting this.***
HP has recalled dv9200 for the hing and is offering free repair.
HP DOES NOT COVER MY DV SYSTEM:
On the DV9200 motherboard part# EZ345AV NVIDIA issue and many other DV systems, HP still refuse to admit that this is a defective product. My Video card also died the same way. I'm trying to get a tech support to help me but they still will not admit that this is defect from the manufacture. I'm continuing to call and I will also submit a letter to my attorney general. If more of us do this we can get them to do something but we all need to do this, please write your attorney general about this issue and copy the letter to tech support and to HP Headquarters.
**NOTE PROBLEM NOT RESOLVED WITH REPAIR:
Since the problem is inherent to the Nvidia Chip being sensitive to high temperature, and since the engineering design of the HP DV series causes the system MLB to over heat the problem will persist even if they replace the MLB, I've read many entries where customers had there MLB replaced while under warranty but the new MLB died months later after the system went out of warranty. The ultimate solution will not be a repair but a complete system swap or refund.

HP "LIMITED WARANTY" :
may not cover your system
Also of interest are laptops covered under warranty.
* This is a very small list and may not cover yours although it should because the problem is being caused by the same hardware.

I realize we aren't talking about desktops here, but is there any degree of customizability in these notebooks? Or is the entire motherboard and other hardware made specifically to accomodate nVidia chips?Since I have never heard this mentioned, I assume it's not possible. But I'd thought I'd ask anyway.
Actually, Intel now has integrated GPU like X3100 which is better than nVidia 6150 or 7150 but AFAIK not on compatible chassis boards (I could be wrong). You can't replace this chipset with a different one on the same mainboard, the pin count and layout are different as is the bios. Just not possible even with all the skill and discrete parts in the world at your disposal, it would need some kind of big adapter board bridge something-or-other.
The thing that might work is if the bottom shell were partitioned to accept more than one mainboard, or they made the mainboards close enough that more than one would fit in the same bottom shell. I cannot speak for all owners of these laptops but my dv6000 board looks to have all the same dimensions and mountings as at least one other series of HP board with an intel chipset, part # 434725-001 & 434724-001 but that would require a different heatsink, different CPU, different factory image. I saw one note that one of these part #s was for a system that had a Celeron M in it so it's even a significant performance downgrade over a dual core Athlon.
So in theory it's possible another mainboard will fit but not at all likely HP would replace one mainboard with an altogether different one and supply CPU, heatsink, and new factory OS image to match it. I'd think they'd be far more likely to send a new replacement system than do all that.
If anyone is interesting in pursuing buying a compatible board and would benefit from high resolution pictures of a dv6000 board I have a couple, but they are too big to post here I assume. What is the maximum resolution and filesize we can post anyway? I didn't see this info in the help topic and there's no point in posting something too big if the forum code is just going to downsize it plus that takes up a lot of bandwidth.

I appreciate the time you take to post replies to our questions and comments. I am sure others do as well, whether they give you Kudos or not!
Thanks for your reply regarding the CPU/GPU replacement--a NO GO effort. However, let's please not turn this Consumer/Community forum into another Business Forum type of mega-thread involving the lawsuit. Your one post was good and needed to inform others but please only update in a smaller, separate post later, if new developments occur.
I understand your frustration and I agree that HP is partially culpable with the NVIDIA GPU issue. I am experiencing daily and sometimes numerous, GPU display errors : "Display driver nvlddmkm stopped responding and has successfully recovered" when performing the most basic of computer tasks such as opening the Internet or other non-GPU tasking operations. If my system fails, I will likely join the lawsuit if HP does not repair my Notebook for free.
However, for now, let's help each other to the fullest extent possible with trying to explain the process/problems and then deal with obtaining legal remedies as needed. HP was once an fine company and I want their many employees to have a job, especially in these troubling economic times, and we all lose if HP fails!

did you see my prior post where the repair center used a board with the new batch of chipsets which are supposedly not so vulnerable to overheat damage?
I do think you and anyone else who has problems should have them taken care of but for some of us it now may be possible to get the board replaced with one that isn't going to fail again in a few months. At least I hope not, but can't know for certain until that period of time has passed.

If there's a way to tell which parts I receive without opening the case and voiding the warranty, I'll be sure to figure it out.
My system is DV9000 EZ345AV
I'm shipping it to the CA service center. I think it's Union City but I don't have the paperwork handy. I agree with you about switching to ATI or anything other than nvidia. I'm planning on asking the case manager if it can be done.
