Main rail / charging circuit issues on Bucky/BenSolo 17859-1 board from Dell Vostro 5581

I swapped the mosfets from the other board, so can't compare them now. (Will be able to when new laptop arrives).

I did quickly check resistances earlier and all were at least in kiloohm range.

I will check the gates and see if they are all switching on.

Just an update on this.

Received the new ISL chips and Mosfets today.

Must have damaged the old ones swapping between boards too many times.

1 was dead short, another had 80ohms between drain and source.

Soldered in the new ones and board seems be working (get the flash codes for missing LCD which is correct).

I have resoldered the EC from the other board for now until such time I get a replacement, or use that board for spares.
