Hi,
I have a Lenovo 305-15IBD. It's dead.
No power, No lights, no reaction to power button.
I have taken a look inside and tested the DC jack. I have 20.76V on 2 pins on JDCIN1 socket on the motherboard.
I also have exactly the same laptop but fully working. I did some measurements and the working motherboard have 3.3V and 5V on PU202 (when charger connected, before power button pressed). Dead motherboard doesn't have 3.3V and 5V on PU202.
Could you please give me some advice on how to test/diagnose the motherboard further. I'm not sure what to do next as I'm a beginner. I would like to learn. Thank you
