Pixelbook won't power on after replacing USB port

After following the instructions in the Google Pixelbook Right Charging Port Replacement guide, my PixelBook won’t power on.

• Pressing the (side) power button has no effect
• Holding down the refresh button while pushing the power button has no effect
• Plugging in the AC adapter does not cause the LED to light (either side)

Might I have missed something? Does an item need to be enabled or reset?
