Default Re: Macbook A1466 820 3437 no chime CPU hot

thanks paulyboy i will return this a1466 with no solution i think,

An identical 820 3437 board shows 69.7ohm in the CPU coils (both) and this one at identical conditions shows 129ohms both... bad i think .and U1950 is ok on all volts involved...verified 3.3v on bios...

although could not test:

spi termination resistors
33khz on u1900

because im about to return and is all packed, i think would mark this as a bad luck one
