Why won’t the power button work after a screen replacement?

So I had a Huawei P30 Pro come into the shop for the first time for a simple screen replacement.

I replaced the screen and the device seemed to functioned perfectly only to find the power button would not respond and/or turn on or off the device.

I know for a fact it was working before. Still with no solution a second P30 Pro came into our shop a week later for a screen replacement again. I just completed the screen repair only to find it has the identical issue with the power button!!!

anyone have any solutions or come across this before!? I’m out of ideas.

Took me hours to figure this out - the cable from the buttons runs to between the motherboard and the frame, you just need to re-screw down the motherboard and circuit will be complete, buttons will start working again.

While still off, hold the power button down for 10-20 seconds, let go, reconnect battery and power the phone on. This works for many

Ah this didn’t work.

I have unplugged and reply the battery multiple times. The only way to “turn it on” is to plug it into the power
