Please create Razer section and move it there, I don't know where to post this elsewhere.

Problem:

I got 2 machines with same problem - no power. Battery controller ISL95520HRZ is not enabling main power MOSFETS.
I have not located any shorts on motherboard, tried replacing with similar IC I had but didn't helped, maybe not compatible (ISL95521HRZ). So it's dead on very beginning of board.

When I tried to feed it on B+ with 14V I got 3.3V on power button. When I press power button I get +5V and +3.3V on coils, PCH also gets power as it heats up a bit, but rest of board is still dead. CPU and GPU not coming up.

Any thoughts on this?

Thanks

Check all mosfets in charger coil.

All mosfets good, any other idea? I ordered ISL95520HRZ so will check what happens when I change it.
