Each work must be paid nothing is for free maybe only the air that we breathe, therefore do not expect my work or of someone else to be for free, respect and appreciate other peoples work because that is in proper order.
Hello everybody, I have slightly water damaged MacBook Air 820-00164, all pub is cleaned and all works, despite charging.
I have changed: ISL6259HRTZ and also same resistors near it.
it works from battery, for example 77%, but when charger attached, it immediately shows 100% and charging symbol, really isn't charging. Also there is no light on charger. also Mac works only from charger.
charging/audio board is good, flex between audio board and main board is also good.
I need advice, how to find the cause? what signal is responsible fo battery % control?
Not know much but based on schematic this 2 lines communicate with battery.
You can check the available schematics 820-00163 and 820-00165 files.
There is a 2 in 1 diode connected to this lines i would test him but problem is schematic in one is No Stuff in other is available look if yours have it but also 2 pull up resistors are available to this 2 lines test them.
Do not wait that i feed you with the tea spoon, the site is full of info have patience searching and reading because this is the great way to learn from others.
