Hi all,

I sent my ProArt Studiobook 16 OLED (H7600, 12th Gen Intel) to the local repair guys to have a very simple DC in port replaced. I sourced the part myself on accessoires-asus (french company) after struggling to find the right part in the UK. It looked completely the same to the installed part from what I can tell. Originally the only issue with the laptop was a bad / loose DC connection, and so the computer and battery acted completely normal aside from a very poor connection that would fail at certain angles. After the repair was completed I brought it home and used it for...

Hi everyone,

I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

⚠️ New Problem: One USB-C Port Only Works in One Orientation...

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.

I got this recently as-is. Gigabyte 1070 video card.

DVI port is removed. I don't know why.
A wire is soldered across two spots where it looks like the DVI port was. I don't know why.

I've read of people simply ripping out DVI ports and the rest of the cards still working fine. Never read anything about soldering a wire in there for some reason.

The card seems to work fine, except it's stuck in low clock speeds. While starting a game or benchmarking, the clocks may momentarily increase to around where they should be, then goes way back down and stays...
