Won't Power On After Cold Start

My MacBook Air is having an issue that when I shut it down it won't power back up again.

While the MacBook is on the battery works fine and charges fine. The MacBook will perform a Restart with no problem.

As soon as I shut the machine down on battery or on charge it will not power on again. I have tried to reset SMC while off and this does not get it to start again. The only thing that seems to get it to start up again is to disconnect the battery from the motherboard, wait a few moments, plug it back in, plug the charging cable in (it does not work just on battery), and power the laptop back on. Once powered on the battery seems to work just fine again (discharges and charges normally).

This is completely replicable. I've installed a brand new battery and the same symptoms occur. It seems that discharging the motherboard allows it to boot again, but what is causing that problem and what can I do to resolve it?

Model details are:

MacBook Air 13" Mid 2013 A1466

Let me know if any more details are needed.

Thanks in advance.

Has anything been spilled on the keyboard. Are you the original owner?

Nothing has been spilled on it in my ownership. I'm not the original owner so I don't know the history unfortunately. What would it look like if something has been spilled on the keyboard?

A small spill to the keyboard would not necessarily be seen, but it usually shorts out the keyboard power button and prevents startup from the board. The only way to reboot it is to disconnect the battery and mag-safe then plug them back in causing a spontaneous boot. Can you give more of the history of the machine.

Sorry, it wasn't clear in the original post. All keyboard keys work fine, including the power button. While the computer is powered on everything works as normal, it's only when Shut Down that nothing works except disconnecting and reconnecting the battery.

@getdizzy tough problem. Let's take a more in depth look at that battery. Please download, run and post an image of your results using Coconut Battery: http://www.coconut-flavour.com/coconutba...

I have to apologise and take back what I said. You were right, it is the power button shorting; when it is pressed while the MacBook is on, it immediately shuts off. Is the only fix for this to replace the top casing including keyboard, or is there an easy fix?
