Hello. On an Asus X550JD (R510JM) I have swapped a dead GTX 850M N15P-GT-A2 with an working N16P-GT-A2 but after doing so I dont see the video device in BIOS (Only Intel) and i get an PCI Express device error. Is it possible to be fixed with BIOS editing, is it something else? Straps for both cards are identical when I take a look at motherboard boarview. 950M came from X751MD.

Hi,
I have this board, where I have exchanged the LGA1151 socket. During testing I discovered, that the large PCIEX16 slot won't by no force work in x16 mode, but keeps to work in x8 mode only.
I tested this with GPU-Z, also with Render Test (but tried also Furmark and Heaven Benchmark - no effect).
Tested on Core i5-9600K as well as on an Pentium G5420 and MSI NVIDIA GTX1070 and 2 other cards, including RTX3060Ti.
Board architecture definitely allows x16 mode, as all 16 PCIe lanes are present between CPU and main GPU slot (nearest to CPU).

ACPI fix!
Yes, you read that right, the bug that HP/Compaq never fixed is finally no more, 16 years later. You probably don't care but here it is anyway.

At boot, you may be greeted by the following message:

I will just preface all this by saying that I have a fairly technical background but have never attempted SMD electronics diagnostics and repair before, I really like the idea and want to learn.
I have a MacBook Pro late 2016 that died maybe four years ago. Over the course of 30 seconds, it got slower and stuttered, until it froze for a second and died. No click from the trackpad anymore, nothing. I started getting interested in electronics repair and decided to give it a shot, so I opened it, removed the battery (one cell was puffy), took out the motherboard and experimented with...Today, 01:53 AM -
