hi
I have this Lenovo ThinkBook 13s-IML and it have no power
19v is present on DCIN pin 17 of charger ic (page 59 on attached schematic)
the issue is that +VSYS is 0.5v pin 3 of charger ic, and it is all over the board on all voltage regulators
I want to understand where does +VSYS is generated and why it is only half volt?
can someone help with this please?
