820-00165 no charge

[arnonabuurs]

Hi Guys, I have a macbook air that shows charging but its not. Under "about this mac" it says charging "no". Also no light on the charge plug. I do have all voltages as the mac is running, PPBUS 8.59 and 3.42 as well, also on the I/O board. Any idea where to start?

Have you tried another I/O cable and board???

Thanks man, got an orange light now after changing the I/O board, so will assemble and hope it charges now, will report back

The ornage light is back, but it still shows no charge under "about this mac", have tried with a new working battery.

Check the usual resistance between 17/18 27/28 on the ISL.
