Test points for logic board
I have 1286 late 2008 15" 2.53 bookPro(serialnumberxxx56D61 GN) that have that problems:
No Battery light on main cover at all
Magsave light changes when charging or with SMC reset
No reation at all at the start(no noise-absolutly nothing)
battery is 2 months old,mag save is 85Watt and about 6 month old, -mac only requires 65 watt refer to the first original magsave.
Have tryed to remove/swap RAM,key options with start and battery remove,Installed new magsave board(bought here-excellent service by the way :-))
Have no acess to other battery(but have my old still working one but not 100% shure how good is it) and other magsave.
I can measure +12 volts on some capacitors on the logic board for example.
is there a scelamtci or similar where i can measure some voltages to exclude possible failure like the voltage/power supply or to know that the display bord is dead ?
I do not have much money just to replace the board and maybe no changes .
I cant find on the logic board the reset or start points to exclude maybe a failure of the power switch(i only found one PCB layout here but that is not my logic board.What at least have the mac to do when i pwer up even for the possibility the RAM are defective(or not installed)?
Please help, iam here in the dessert(Austria) very rare to get some parts to try, but iam a very experienced technicians(electronic and mechanic) but a PC dummy,
and with my infos i cant go further.
Ist dies eine gute Frage?
