How do I power on a Chromebook with a dead power button?

I’ve got a Acer Chromebook 14 that I’m doing a screen replacement on. The power button was known to not work before the repair. The customer had simply been opening the lid to ‘turn it on’.

I disconnected the battery before doing the repair, and now I can’t get the Chromebook to power-on again when opening the lid. I’m assuming it was in sleep mode before, but disconnecting the battery did a hard shutdown.

I don’t have the charger, but I will try hooking it up to my bench PSU. Does anyone know what I could try to power this thing up?

Any help very much appreciated!

Typically opening the screen should boot the Chromebook, if it doesn't there might be some screen issue or it might just not be charged? Did you try plugging it in?

Soldered a couple of wires onto the DC power jack socket. Thankfully the Chromebook powers on when the charger is connected. Now it powers on when the lid is opened. :)
