Hi,
I’m trying to fix an HP EliteBook 840 G6 that stopped working after a lightning storm.

– Charger is OK and 19V is present at the motherboard.
– No charging LED, no fan, no reaction.
– I don’t see any 3.3V or 5V near the coils.
– Battery is unplugged.
– I’m new to board repair but can use a multimeter.

I added a clear photo of the board.
Any idea where to start or what to check next?
Thanks a lot for your help!...
