Few interesting observation for Lenovo Legion 5 NM-D562 Motherboard

[mcplslg123]

01.This model uses a 300W USB type adapter and the ADAPTER_ID voltage is 3.0V/Resistor used is 750 Ohms(On internet it's mentioned as 8.6K ohms)
02.This model will give "Underrated Adapter Warning" if you turn it on with Adapter only. Once battery is connected,it charges and the adapter message goes away.(Wasted 2 Hrs trying to fix that)
03.This model wont power up by switch only on adapter(Will boot directly on adapter only if cmos removed). Will power on with button only when adapter+battery is connected.
04.The most common fault on this mb is 1.8VS drops down to 1.0VS even though 1.8VALW is at 1.8V. The reason is leaky cap CX33/34/35

Hope this will help members of this family. A lot of my time (almost 3 hours) was lost trying to fix a fault which never existed.

I have a problem with the JDDRH1 RAM slot. It happened during the Windows update, which probably led to rewriting the bios.
It arrived on the table as non-functional. After removing Ram 2 (closer to the processor), the laptop started up. first thought, defective ram, but after testing my suspicions were not confirmed, in slot 1 it works fine, however, as soon as I install a type, it remains non-functional, it is also non-functional when only slot 2 is installed.
What could be the problem with this slot? mechanically everything is ok.
thank you
