Thanks. As long actually my main pc too has problems (my RTX 4070 super has massive VRAM problems) the prioritys have changed. But good to know where I have to look.
If I have news I will tell here. 👍

So it looks like I have to get a EMB04N03H. 🤔
Will look on monday in our company. Maybe there are some in the "assortment drawer" of our electronic engineers left over from older projects.Leave a comment:

Guys, maybe I´m not good at newer high integrated electronics (I´m 62 and learned the electronics job in 1982) but I can read a multimeter. 😉
The difference (1.3 ohms) probably depends on a little shakey fingers while measuring AND make the picture with two hands only. Was between 1.1 and 1.2 most time....Leave a comment:

R is Ohms. Sorry, sometimes we are used this naming in the industry.
I always cleaned up my workpace. It is a automatic scaling multimeter (see photo). Not the newest, but not bad at all.Leave a comment:

Lenovo 730-15IWL No energy
Hi everyone.
I have a Lenovo Yoga, where the charging doesn't work.
- No charging/Battery LED, even with battery disconnected
- power supply is tested and okay (65W and 135W version tested)
- onboard fuse PF202 is okay
- until cable I can measure the voltage (Clip22 removed, measured the wires).
If I press power button, a little "click" sound from speaker appeares. Seems he want to start, but not enaugh battery.
I think it is the FET PQ302 (see picture). Looks a little... defective in one corner.
Can anyone tell me what type...Last edited by dagolard; 09-05-2025, 01:18 AM. -
Hi everyone!
I'm Holger from Switzerland, 62 years old. Skilled electronics and PCB Layouter, I'm "out of business" for over 10 years now. I'm here to find some help for complicate problems, especially in the PCB repair area. Let's have fun!
Greetings HolgerLeave a comment:
