How do you jump start a 2015 MacBook Air

I have a customer's MBA which got drunk one night recently on tequila and orange juice... Now it does not power on at all. Nothing. I found a page which shows how to jump start older machines, and have successfully used it's tips on those machines. (http://www.insidemylaptop.com/turn-on-ma...). However, they don't have one for the 2015 MBA, so I am asking iFixit community if anyone may know where to find the power-on pads for this model... It looks to be getting power from the charging port, as I see voltage on the battery, but not much... Maybe the problem is elsewhere, but I don't have any schematics or diagrams to refer to... Can someone point me in the right direction?

thanks!
