I recently bought a Pi-top . Connected it to an unofficial 15.3W adapter, and could not boot. Switched to an Apple 85W adapter, and the pi-top booted and charged fine.
However, the apple adapter is needed elsewhere, so I got an official Raspberry power adapter. The result is the same, the pi-top does not charge.
I’ve installed a raspberry pi 4 8GB in the pi-top, and everything except powering from a 15.3w adapter works as expected.
Any help is appreciated.
