HP Envy 15t-j100 System Board

[cbecker301]

Hello all!

I just recently brought my laptop in to be looked at/repaired. The local technician told me that my laptop system board died due to the Windows 10 updates not playing nice with my old Windows 7 operating system (originally, my laptop had Windows 7 Home, last July I upgraded to Windows 10). I have started to look for a new replacement system board, however I have a few questions. I looked at the service manual for my laptop and can't figure out which replacement system board is adaquate/what they all mean. The serial number of my current system board in my laptop  is 720566-001. I googled this system board number and keep finding results with 720566-501 and 720566-001 in the title for the same system board. Most boards I find on eBay also have the number as 720566-501. My question is this: Will I be able to use a 720566-501 system board to replace my current 720566-001 system board? 

Additional details:

-12 GB RAM

-Intel I7 2.2 Ghz processor

-1 TB SATA Hard Drive 

-GeForce Graphics Card (not sure which type)

-Product No. E1P05AV

Hi,

Looks like the system board of your machine is very rare, only 4 products use it as shown:

(Normally up to over 200 different products use same system board)

You can buy from the above Store.

Regards.

Thanks for the website! The website I am questioning is this one 

http://www.aliexpress.com/store/product/720566-501-720566-001-motherboard-for-hp-for-Envy-15-laptop-...

where it appears the two boards are being sold as the same. Is this incorrect?

Hi,

There are dozens (if not hundreds) of HP Envy 15 models/products around, your machine is an HP Envy 15t-j100 which is a CTO machine. You can see 720566-501  is for many different models/products:

     http://partsurfer.hp.com/Search.aspx?SearchText=720566-501

for your machine its part number is 720566-001. 720566-001 and 720566-501 may be VERY similar but not the same.

Regards.

That makes sense, thank you for the clarification. I have been doing some side research- from my understanding if I put in a different system board other than currently installed, say the 720566-501 version instead of the 001 version, the recovery drive will not be able to recover the OS. However, I have a Windows 7 and 8 boot drive with product keys available to me. If I remove my files using a SATA to USB adapter from the hard drive and install a 501 version system board rather than the 001 system board, could I use my Windows 7 boot drive to reload the OS?

Hi,

You can always try a different one and you can get 50%/50% or use the right one with 100%. Have you read two links above ? Put Windows 7 to 501 the chance is not 50/50 anymore.

Regards.

What do you mean by trying a different board and getting "50%/50% or the right one with 100%." Do you mean there's a 50% (or less) chance it will work with a different board and 100% chance it will work with the exact same board?

Thanks!

Also, I have read through the two links as well. This part about computers is a bit out of my skill set, so I want to be educated before I begin purchasing any replacement parts
