#1 ASUS Vivobook M7600R (M6500RC R2.0) - 19V Power Rail Not generated, AC-Detect

Hello
I have an ASUS Vivobook M7600R which I received, the laptop did work on battery but now battery is depleted and it will not charge, or laptop will not power on from adapter.
There was some sort of surge and the ISL9241H chip was burnt on the battery CSON and CSOP lines and the battery charging side was short ~10ohms.
I have replaced the damaged ISL9241H and two mosfets on the battery side that are also damaged and now the short is gone and there is now 19v powering the ISL9241H but the main 19v power rail is not being generated.
The ISL9241H appears different to others I have worked with in that the AC-Detection looks as if it happens elsewhere and passes just the AC-OK signal to the ISL9241H. The ISL is getting 19v DCIN but there is no VDD on pin 18, without a schematic for this board I am having trouble finding the fault.
Can anyone help? Thank you.
