#1 HP ZBook Studio G3 (Mobo. APW5U LA-C401P Rev:2C) - 19V ON and OFF Every 2 seconds

Hello Everyone,
When I plug power in every 2-3 seconds 19V is ON and OFF.
I know that MOSFETS are being switched ON (25V sent to their GATES) by Charger IC BQ24780S.
Can Charger IC cut off power or more likely problem is with KBC as the reason of resets/restarts ?
I have sent my thermal camera for repair and I have a problem to identify possible faulty component. Resistance on all coils is correct. No shorted circuits.
Has anyone had the same or similar problem please ?
Thanking you in advance.
Regards,
Rafal S.
