Title:

What is the voltage from the charger suppose to be?

Text:

I have a Macbook air 1466 with liquid damage. The macbook still works but has some malfunctions which I'm trying to fix. I have the schematics for this model and this says that the voltage from the adapter should be 18,5 volts on PP18V5_DCIN_CONN. I have 16,6 volts here and I cannot find a short.

I'm in doubt that the schematic is the final version and want to know for sure that the power rail is really suppose to be 18,5v before I set 18,5v from my power supply on the rail to find the short.

Can somebody confirm that this macbook uses 18,5v and not 16,6v?
