Lenovo g40-45 switch no respons

[Yosua]

Hi technician friends, I hope my colleagues can help with my problem with the lenovo g40 45 NM-A281 mobo, the case is that the laptop only lights up the charger light with the battery when connected to the charger, the 19v PR53 voltage is safe and the voltage at 3v and 5v is safe too , but the switch doesn't respond

This measurement uses the buzzer mode on the PL

PL3=445
PL4=030
PL903=116
PL402=316
PL401=309
PL501=066
PL602=156

You need resistance value to ground on all could and write on hd picture of the board and upload to it. Did you reset the bios. Remove biosbattery short the two pins and put it back.
