To moderator: 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 |

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