Default [Q] Broken power button workaround

So, after recently getting myself a new screen and a back-housing, I took my phone apart, and accidentally snapped the ribbon cable that connects the power button, (should've been more careful). Anyways, now i'm stuck with a phone that works perfectly but doesn't turn on, I ordered myself a new power button but it'll take atleast a week to arrive, so. Are there any workarounds for this? I've tried adb, but it comes back with a "device not found" error.
