I need to find out which motherboard is in my pavilion intel core I5 8th gen?

[Jcha230]

I need to replace the motherboard in the pavilion which I broke the connection between the hard drive and motherboard therefore I cannot turn it on. I need help in identifying which motherboard to replace it with. How do I identify which part will work?

Here is the Service Manual:

Manual 

Any of the system boards listed on p. 24 would work but this is your exact replacement:

Equipped with an Intel Core i5-8250U 1.80-GHz (turbo up to 2.20-GHz) quad core processor
(2133-MHz FSB, 4.0-MB L3 cache, 15-W), a graphics subsystem with UMA video memory,
and the Windows 10 operating system
935890-601

HP no longer stocks it:

This eBay seller has used ones:

Post back if you want more help with this. Likely we can find it a bit less expensive and a new HP Part.

Thank you for the assistance. Do you have an upgrade you would recommend over replacing the original? Additionally it needs a new battery,  apparently the battery was recalled but I did not know this as my daughter never registered her machine. The battery is TF 03XL. Lastly what about a hard drive upgrade? Recommendations? Thank you very much.

This would be highest and best:

You can probably use the existing motherboard if all you did was break the SATA connector for the original 2.5 inch hard drive. There is an M.2 slot for a solid state gumstick type drive. Post back with a few more details on the hard drive issue and we can work out your best options.

Greetings, you stated I could possibly continue to use this motherboard. I have attached a photo of the connector that is broken off the motherboard. I’m not sure how to do the other connection you mentioned but I’ll research that. So what do you think reuse it and connect the hard drive elsewhere? Or new motherboard?

thank you

[Jcha230]

Photo of broken connection, fixable? Workaround?

thank you

[Jcha230]

[Huffer]

Likely not fixable. Does it still POST? Obviously no hard drive action without that connection. Here is what the motherboard looks like:

M.2 slot circled in red

So into the slot circled in red you can put one of these:

For $60 that is a heck of a deal. I see you already have the laptop open so confirm that there is a slot where shown and as long as the motherboard POSTS ou should be able to use the gumstick SSD as your storage instead of the 2.5 inch hard drive originally fitted. 

[Jcha230]

So if it does POST and accepts the gum stick SSD I would no longer use the solid state hard drive? I could just remove it?

thanks again for your assistance!

[Jcha230]

I put it back together without connecting the hard drive obviously and got to the page shown in the photo. Does that mean it passed the POST?
