Isolating MacBook no power issue

Hi Everyone,

I have a 13" Mid 2012 Macbook Air that has stopped turning on.

I have tried multiple known good chargers - no light on any of them.

SMC Reset, unplug battery + power button all did not help.

No activity at all upon powering on. There are NO battery status indicators on this model to tell if battery is charged at all..

I assume that it is either the logic board or the I/O..

Is there a way to isolate this between a faulty logicboard and a faulty I/O Board?

I understand the $90 I/O Board would be a better place to start then the $400 logic board - but was curious if there was anything I could do to test for sure which is the failed component. Is there a way to send power to logic board bypassing the I/O Board? It's likely the battery is completely discharged so I don't think shorting the pads did not seem to work, due to I'm guessing no power in the system.

Thanks in advance

There's really no way to tell until you drop in a new battery, get it started and run diagnostics.

Is there no way to power the mainboard directly?

I have a similar problem with my MacBook Air Mid 2013. Was working great the previous evening, then the next morning it would not power on. Plugged in with a new power cord - nothing. Replaced the I/O board, nothing.

Does this narrow it down to the logic board?
