Iam not sure. Here is a schematic of this chip. I mesured (12.38V on VIN) and (3.3V on V02) and (0V on V01) is V01 the output of 5V?
I mesured (4.99V at VREG5)...Last edited by kennethf; 12-06-2012, 10:08 AM.Leave a comment:

I think I have found one of the problems, there is a chip (TPS51125) that makes 3.3V and 5V and this only produce the 3.3V. So I have ordered a new one and hope this will make the macbook happy

Thanks I think you are spot on when you spotted that I dont have any 5V but I have problem to find out where the 5V supply is on the PCB....Leave a comment:
