I have HP probook 650 G2 but the network port does not work. It is not a software problem because the installation is done more times and drivers are reinstalled. It is hardware problem, can anyone help with this?

Re: Hp Probook 650 G2, network port not working
So this confirms that the logic side is working with the PCI or PCIe interface of the ethernet controller reporting their IDs to the host pc.
Is the rj45 connector for your cat5/6 cable look ok?
Perhaps the contact pins are mangled?
Do you see any different ethernet light patterns when you attach the ethernet cable vs. remove the cable?
Any burn marks near the ethernet connector region? Perhaps an external surge that took this out.Comment

I too will suggest to replace the RJ45 Connector.Comment

Gotta check if it has a valid MAC address, if it detects a cable plugged in and if it negotiates speed and duplex properly.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

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).

I have a Dell Latitude 7410 with an Intel i7 10th Gen CPU. The USB Type-C port is not working, and since it's the only charging port on the device, I'm unable to charge the laptop.
I inspected the motherboard and found that the IC labeled TPS65988 had a short circuit. I ordered a replacement IC from Alibaba and replaced it. The short issue is now resolved, but the laptop still doesn't charge, and the Type-C port remains non-functional.
After doing some research, I found out that the TPS65988 needs to be programmed after replacement in order to function properly.
