Hello, thank you for your feedback. This experiment can determine whether the motherboard or the 4pin laser line is faulty. You can replace a line to determine whether the 4pin laser line is faulty, so that you can finally determine whether the motherboard is faulty.

There is another possibility that the low-light setting of the laser is too dark. I noticed that the laser working status and feedback are normal;
