DV6000 - compatible motherboard

Hi, I have a question about finding a replacing a motherboard for an HP DV6105US laptop. I need a replacement mother board for my friends laptop. He has a DV6105US, Part No: RG253UA. I put that part number in HP’s partsurfer web page (http://partsurfer.hp.com/Search.aspx?SearchText=RG253UA) and it says the original motherboard is part number 431363-001 but it is no longer available for purchase so it says to order part number 443776-001 as a replacement.

Now I found a real good deal on a different motherboard, the part number is 433280-001 I can get a brand new one for around $43 (including shipping) from ebay. I went to a few websites (http://www.getpartsonline.com/433280-001.html is one of the sites), and they say the board is compatible with that model. So I was wondering what the difference is between this part number (433280-001) and the recommended part number (443776-001). I know sometimes the DV6000 series laptops overheat, so would the 433280-001 be more susceptible to this issue since it is not the suggested part number to use (although its compatible)?

Not sure exactly what the differences are between the two model numbers you display.

I went to my go-to place for laptop parts and have found this one:
Which is a link for the recommended part number for the RG253UA Part number.

Here's another site:
Not familiar with them though, but the price is not to bad. $55. Refurb.

Also on Amazon:

I suggest going with the recommended.  
I've just linked you to a few that are close to the price....of your ebay one.   Always best to go with the recommended one.
If you had gone to the Support and Drivers link at HP.com, you would have found the service manual: http://h10032.www1.hp.com/ctg/Manual/c01035677.pdf
You have a "defeatured" model and there are two different base assemblies which means there are extra connection holes in the "full featured" models and the one listed at getpartsonline is wrong!  It is for the full featured model and will give you grief.

Now; the problem with these systems (and numerous others from Dell, Sony, Gateway, Apple, etc.) is that NVidia mounted the silicon in the carrier using a defective heat bond and the carrier warps when it heats up (much like a cookie sheet will pop in the oven)  After numerous heating and cooling cycles, the carrier pops loose from the systemboard and the stuff hits your fan.
The only real fix is called reballing where the part is removed, cleaned, and then reattached with higher grade solder balls.  (Some silver content increases the strength tenfold)  But; there are many article about using a heat gun or an oven (aka reflow) which is only another temporary fix or, what HP did, was to put glue on the corners of the part which also doesn't work and makes it almost impossible to reball later.

I replaced the systemboard in one for my daughter to use only to have it fail again 60 days later, so don't have much faith in replacing the board as HP dumped thousands of bad ones on the market.

But; if you are willing to risk it, you do need the De-Featured board: http://www.google.com/#hl=en&sugexp=pfwe&cp=10&gs_id=4&xhr=t&q=443776-001&gs_sm=&gs_upl=&um=1&ie=UTF-8&tbo=u&tbm=shop&source=og&sa=N&tab=wf&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=dec22f9bde300d47&biw=1297&bih=769

DavisMcCarn - I actually did rework that board (the original problem was no wifi) and the repair lasted just about as long as yours did, about 2 months before it failed again. I have not learned reballing yet but plan to do so soon! I had no idea about featured and defeatured boards and components but it maks sence because I see lots of times on boards that components are not installed allthough the boards have fitting marks on them (for the components such as usb, ect).


See my comments above (in the last post) for more info

There's many techniques to reballing, youtube will have lots of guides...
do a search for HP DV reballing
and you'll find a bunch.
