One end of the hinge on the Google Pixelbook Go has slipped out of place. I do not know how to reinsert it. The two pieces of the clamshell do not feel flexible enough to bend and allow the pin to slip back into the hinge.

Curious what you ended up doing here. Your issue (and mine) is that the hinge itself is broken. This is caused my the screws loosening causing a torsional flex in the hinge when then snaps it. The screws loosen over time due to hinges being too tight. Google isn’t supporting the devices and there’s no way to get replacement parts.

It seems that the hinge is snapped from the image. Could have happened when the LCD is accidentally pushed exceeding the limit. Can be fixed by removing the back cover and swap out the damaged hinge.

I was able to buy a hinge on eBay (at outrageous price for such a small element) and replace it, otherwise you can replace the whole unit for $$$.
