Comment on USB-C PSU is 9v *only*. Is that compliant? Did a PD-compliant charger fry my gear?
evenwicht@lemmy.sdf.org 2 days agoDead battery was my 1st theory, but it’s questionable. I fiddled with a healthy demo unit (same model) at the store. The battery ran out of juice and the machine shut down. I plugged it in and hit the power button and it instantly turned on. So it can apparently run directly off the USB-C as the battery charges (and the manual says as much). But the one I have never powers on, even when connected to power.

There’s a wide voltage difference between “I’m dead, charge me” and “I’m so dead any half competent charging circuitry will refuse to charge me lest I combust”.
If it’s fuggered, you’ve got nothing to lose by opening it up and seeing how hard replacing the (probably 18650 Li-Ion) cell(s).
Good chance they’ve got solder tabs spot welded onto the cells, but that’s not a showstopper, you can buy em that way if you don’t know anyone with a spot welder.
