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.
