Pavilion DV9500 motherboard WLAN compatibility

[cpuwrite]

I have two HP Pavilion DV9XXX laptops.  They were under repair a while ago when the roof on my residence collapsed.  Some of the parts got mixed together and some were lost.

I recently put a motherboard in one of them, and it started giving me messages that the WLAN modules I was using with it were not compatible with that motherboard.

I corresponded with an ebay seller.  I gave him the model number off of the bottom of one of the laptops--the part did not get lost--and of the main board and asked him if he could look up the number and tell me the part number of the correct WIFI module.  Instead, he told me that I had the wrong main board.

I really don't want to bother the gentleman.  I would much prefer to be able to take the model number of the other laptop and look up the WLAN module part number from that (and be able to resolve other compatibility issues as well).  Does anyone know where he would have gotten those part numbers from?  Where I could go to look those things up myself?

Hi:

Check chapter 3 of the service manual for the list of parts and part numbers.

Thank you for your reply; however, I already looked that manual over (though I checked it again in response to your kind message).  I use the manual when I'm assembling/disassembling my machine(s).  Chapter 3 lists parts that are available, but does nothing to show which ones are compatible with each other.  It does not have what I actually need--a listing of "THESE WLAN modules go with THESE mainboards."

Thank you anyway.

You're very welcome.

It is my understanding that this is how it works...

If your notebook has an Intel processor and chipset, you can use any model wifi card listed.

If it has an AMD processor and nVidia chipset, you can use any model wifi card listed, except an Intel card.

For example:  I had a dv6810us with the amd Turion processor and nVidia chipset.  The model is the same as the dv9xxx, except it has a 15.6" display.

I looked up the list of supported wifi cards in the dv6500, 6600, 6700 service manual

The original wifi card it came with was the Atheros AR5007.

I wanted a dual band wifi card, and the only one that would work in my model was the same one listed in the manual I posted for you...the Broadcom 4321AGN 802.11a/b/g/n module, for use in the USA/Canada...Part # 434661-001.

I bought a used but tested and working card on eBay for I think it was around $7.50 delivered.

Removed the Atheros card, installed the Broadcom card, and I was off and running with dual band wifi.

But the info you are looking for doesn't readily exist.

You would need to know what the original motherboard was that was installed in the product number of the PC you have.

Then you could look up the product number of the notebook in the HP parts surfer website and see the actual wifi card part number that was installed in that product number.

I guess you  can take the product number from the notebooks you have, look them up and see if the motherboard part numbers match what you have, and see the wifi cards supplied with the product number of the notebook.

Or enter the motherboard part number in the above site and see if it gives you a list of notebooks that motherboard is used in, cross reference it that way. Get a model that motherboard was used in, look that up and see what wifi card came with it.

I have entered the product number of the dv6810us notebook I once had in the partsurfer website, and here is what you will typically get...

Thank you again, but I've really, really REALLY had it with this thing.  Yesterday, I put in the THIRD replacement mainboard, using the service manual, so I could do everything literally by the book.  I pushed the power button.  The LED's went on for five or 10 seconds and then it just shut off--no error codes, no nothing.

No more.  I don't care how good the screen is or how convenient the remote control express card is, it's just not worth it.

Thanks, but I've got a couple of computers to sell "AS IS, not working, for parts or repair."

I know I'm coming into this late in the game, but I've had similar problems and I found out how to fix them.

It is possible that your CPU/GPU is overheating and the system is shutting down to keep it from burning up.

The way to fix this is to put heat transfer paste between the GPU and the head sink, and it won't hurt to do the same to the CPU while you're at it.

Imagine that.  I solved my own problem!
