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.

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; Today, 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!
