I like the kind, the stile, you make videos. Explaining point by point with the measure animation. I found you a month ago and now following this channel. You do all the same way I would do too (check main power rail, then 3,3V rail). Hope the other boards you bought have some MOSFET, capacitor, BIOS or super I/O chip errors. But no Intel Core shortage, which can't repair because there are no chips on the market. Let's see what happens in the feature in the EU (I am from Germany), we will get a new law named "The right to repair", this will change in Europe the situation about repairing stuff. I agree, maybe the pre owner had dodgy RAM modules or not reset the BIOS.
@user-qc9yz9jd6r: I read it on L. Rossman's channel: "80% of our society is immersed in: use it and throw it away! For the other 20%, in the case of electronics and even other trades, Louis leads here in North America , the "fight for the right to repair." Let's hope that there (EU) and here there will be changes beneficial to everyone (buyers, companies and people dedicated to repair). My best wishes to you and everyone.
Motherboard: SNOWI - 6050A2677101, MB-A01; for HP models: ProBook & Notebook. That's how we know it here in North America. I saw the part numbers of some components on the PCB and they match (are similar or equivalent). Thank you very much for sharing your measurements of a working board (so we can consult in case of failure). Please keep uploading content. Thank you again for your time invested (the video is 9 minutes long) but preparing it is a very different thing and we appreciate it. All the best.
As we learned with the Dell LA-F114P motherboard that you helped me repair, it is always good practice to measure those first two MOSFETs. Even though we found a shorted capacitor on the main power rail, those two MOSFETs also needed replacing, but it took me nearly a year to figure that out. A faulty first MOSFET exhibits certain symptoms, and a faulty second MOSFET exhibits its own unique symptoms. It is good to know the difference.
There are multiple paths to ground. In continuity many meters are constant current, so as the minuscule current is divided across the other chips and components like the bq chip, lower the voltage drop will be. The actual voltage or resistance value is fairly immaterial, you are just checking it is not shorted to ground.

Hi everyone, could someone explain to me why in diode mode measurement it starts with 1.6v and after the sensing resistor it is 0.4v?
