Ask Lenovo P14s Gen 4 // NM-F431 Rev. 1.0 // KT4D4/KT4DE/KT6DF/KT6DG

[hands-on-security]

hey there

I am looking for the schematics and silkscreen for the Lenovo P14s Gen 4 // NM-F431 Rev. 1.0 // KT4D4/KT4DE/KT6DF/KT6DG.

I have the issue that the device isn't booting anymore and only shows an orange led next to the power on button once the power cable is connected. Further I have a high frequency sound and some caps which have like 16Ohms of resistance. I think some fuse or a bad cap is lungering around on it.

Any ideas/advice is welcome, but I think with a schematics I should be able to find it.

Thanks and have a nice weekend!
HoS
