DELL 5537 LA-9982P - not work after lightning strike

[ktmmotocross]

Hello.
Have this DELL 5537 LA-9982P that not work after lightning strike to house.

i replaced PQ701 but now have only 5.5V after it. ACDRV have voltage only for a moment when attach charger. BQ24717 have ACDET 2.58V, VIN 19V. Dont have this charger ic , can be replaced by other like 737?

How to check if PSID is ok?

Remove the 4k resistor on ACDRV pin. Check again to see if the proper ACDRV voltage to ground of ~25v is present at the charger IC.

no voltage on ACDRV when removed PR703.

Confirm voltage on REGN pin # 16 of the charger IC.

Next, remove all power, meter in resistance mode.

Measure the resistance to ground of the ACDRV pin on the charger IC.

Was PQ701 new?? I still think PQ701 is faulty. Measure resistance on PQ701 pins between
01. D1-D2
02. D1-G
03. G-S
