Core i7-10750H - GeForce RTX 2070 - 1080p

Not white or amber. Tried a different power supply; no joy. Opened the laptop and measured the voltage on the 20 pin connector that goes from the Power connector to the motherboard, and it measures 19.6 volts.

Removed and tested the SSD and HDD. Both work. (I backed up both while I had them out of the laptop.)

This is for oldturkey03 ---

I started disassembling my HP Omen 17, and came up with the following designation from the motherboard, as you instructed:

GPC72 LA-J672P

Rev: 1.0

2020-03-26

Made In China

Let me give you a few of my thoughts and delineated abilities.

1) I have done a fair amount of PC board soldering, but none of in on surface mount devices.

2) This laptop is very nice (when it works), and has three display surfaces: the laptop and 2 external HDMI monitors. (It runs Linux Mint 20.)

3) If the motherboard should be replaced, so be it. Please advise.

4) I managed to crack the little blue connector at the top of the second photo - it connects to the thermal sensor - (JIR1).

It is a six conductor ribbon on a reverse ZIF.

5) If I replace the motherboard, can I remove the processor from the old motherboard, or does the new motherboard have a new processor?

Dear oldturkey03,

Like a fool, I didn't save my last post, so I am doing it all over again.

I am going to post an answer, rather than risk losing my comment again (and this time I will save the text).

There are 19 photos which have been uploaded to the media center. They represent the component side and solder (for lack of a more descriptive designation) of the mother board. The zoomed out component side (with the Fluke meter) is followed by details of the component side.

The zoomed out solder side is followed by detailed photos of same.

If you can help me to troubleshoot this motherboard, that would be very kind of you. As you indicated earlier, a new motherboard would also contain the processor and Nvidia; so that is not a viable option. Since I really don't have the skill to do surface mount soldering (except very limited), would you be able

and willing to suggest some party who could handle this for me. I live in the mid-West.

Thank you for your patience.

Blessings,

George

Dear oldturkey03,

You requested better detail on IC UV42 and UV47. The two new photos are different views of these two chips.

Now it won't start, although the power button does turn red for 3-4 seconds when I try to turn on my laptop. The screen stays black during this time.

How can I fix this?

Thanks in advance!
