Motherboard schematics for HP OMEN Notebook - 15-5108tx

Hi All,

Looking for the chip diagram/schematics for the above HP model.

The Motherboard number received from HP support is 806345-501.

Any help would be appreciated.

thanks

Roy

Thanks for that Jayeff, had a close look on the motherboard both sides, i’ve attached photos of the board perhaps someone could help me find this board model number?

Thanks @jayeff, your help much appreciated. I've checked both links for schematics and both are not correct system. What I really need is to identify the chip that got fried. which looks like its marked on the board as "C2503" next to the white battery connector. Unfortunately as it is fried its id number is partly invisible. Any ideas how to identify which chip it is? On a second thought I'm not sure the schematics would help, maybe a boardview? Any ideas how to find the chip number?

Here are a few closeups

Yeah, I gave the old battery away, but might still be able to retrieve it for testing.

Really appreciate you help mate, you’re a champ!!

Hello Roy,

I have a dead one as well. Unfortunatelly I can't see any burn signs on it.

The part number you are looking for is 3D US or U5

Sorry my phones camera is far from perfect

Hi @roymal ,

To find schematics for motherboards (or any circuit board) the board number information is required as it may have been made for the laptop manufacturer to order by a different manufacturer The board manufacturer’s name may also be on the board along with the board number and revision state but sometimes not.

The number that you have been given is the HP part number for the motherboard, not the board number and searching online using this part number or the laptop model number gives no results for the schematics.

What is the motherboard's board number? The board number is printed on the motherboard itself.

Here's the maintenance and service guide for the laptop, taken from this webpage. Go to p.36 to view the necessary pre-requiste steps and then the procedure to remove/replace the systemboard. You don't have to remove it but this should be helpful in gaining access to it to find the board number. Apologies if you know how to do this already

When you have found the board number search online for (insert motherboard full board number information) schematic to hopefully get results.

If you find the schematic (or the board number) and you need more help, post back here

Hi @roymal ,

Bit of information, hopefully not sending you totally off on the wrong track.

Found this link that says that HP Omen 15 / HP pavilion 15 laptops are a Quanta motherboard series G35D

Found this link to a Quanta G35D R1a schematic.

>>>>>>>>>>>>>>>>>>>>>>>Disclaimer<<<<<<<<<<<<<<<<<<<<<<<<<<<

Nothing is to say that this is your motherboard but it may be a starting point if a few things line up between the board and the schematic

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I also checked under "M2X20PA" as this is the product code for the exact laptop but no joy there either.

Maybe you could gently peel off the sticker that says to "Replace with HP spare 806345-501" and see if there is anything on the board underneath it.

Also to make things easier for you in the future perhaps here's how to add images in ifixit Adicionar imagens a uma pergunta já existente

Maybe @oldturkey03 will have some ideas as well.

Hi @roymal ,

A C identification on a circuit board means that it is a capacitor. If it is fried I daresay that an IC component (Q designation - transistor or D designation - diode) nearby might also be faulty as well. Usually capacitors only have 3 digits if they're a smd type component. Post a close up image of just that section of the board.

Hi @roymal ,

It's not C2503 that is fried it is Q2501 that is the faulty component. Designation Q means that it is a transistor of some type.

Looks like you may be in luck with more info from this link at least as to what the component is but maybe not why it failed

Also it appears that you're not the only one to have this problem with the motherboard.

The schematics would help as they would show what the component connects to which would help in knowing what it did and you could test the components further on in the output circuit path of the transistor to see if they're OK or not.

Components burning out are due to excess current flow, so either the component itself failed which can happen or other components have failed and this altered the circuit characteristics or there is another introduced problem such as water entering or someone checking with the power still connected and not being careful and creating circuit paths that weren't meant to be there in the first place.

Wow, amazing @jayeff, good to know i'm not the only one changing battery and burning a board on a clients dining table :) After reading all the occurences of Apache2223 in Digi-key forum I feel it would be wiser not spend more time and I'll order a replacement board. The only question left unanswered is what caused the chip to burn and is it related to that replacement battery that might burn another board? what do you reckon?

por

@roymal

I don't know.

It may depend on whether the component is downstream from the battery or upstream i.e. is its output feeding into the battery so that if there was a problem in the battery this may cause it to burn out or was it on the motherboard so that battery wasn't the culprit.

Was the replacement battery an OEM battery?

Having the schematics would help here.

Two options maybe if you still have the old battery.

Replace the component on the board (didn't check as to the cost so don't know if this is worthwhile or not) and insert the old battery if you still have it and check what happens. If OK as far as the component goes, then install the replacement battery and check

Buy a new motherboard and use the old battery to make sure that the motherboard is OK and if so change to the replacement battery and check.
