Is it possible to turn on Nexus 6 straight from mother board if power button isn't an option?

After buying a new battery, thinking mine was caput, I opened my Nexsus 6 to find that my Power ribbon had melted and split apart. I ordered a new one but it didnt include the "power flex to motherboard." So I'm now waiting until Monday for that. But there must be some way to power it on until than? The phone I'm currently using I can't stand. Thank you for trying to help.I very scoured the net looking for an option.
