Happy New Year
the processor is 2.26MHz core 2 Duo 13".
On SMC ic is written 3089 or 3039 and 340D.
This board i purchased from ebay and unfortunately the seller disappeared therefor i can not contact for more info.
the board when was received supposed to be a working one but it was defective and i fixed it.
I used schematic macbook pro A1278 820-2530 that was more near to board.
So i went thru the RAILS test and all voltages are there. the only difference i have is PPVCOPE_S0_CPU i got 1.08v and on schematic says 1.5v.
That is why i said it is a bios problem.
do you have any suggestions.
There is one IC U9000 pin1 is LVDS_IG_PANEL. there i have .2v and sometimes .5v but there is no short. pins 2&3 have 3.3v.
tracing pin 1 goes to a resistor which is 0v ( measure resistance is ok) and
then goes to graphics ic. Pin 1 should be 3.3v.
can i fet from somewhere!
Thanks
