ZED Box Orin cannot power after being charged overnight

Hardware ZED Box
1

My ZED Box Orin cannot power on after being left on overnight on power. Now it shows no power at all (no Power LED, no fan, no HDMI signal).

Symptoms

  • Completely unresponsive: no LEDs or fan spin.

What I’ve tried

  1. Fully disconnected both DC barrel and any PoE (none connected now), waited a few minutes, then DC-only power on.

  2. Removed all peripherals (HDMI, USB devices, Ethernet) and try power the ZED box on but failed.

  3. I currently don’t have a USB-A ←→ Micro-USB cable to test OTG/Force-Recovery.

Given the above, could you advise next steps? I can provide photos/videos and any additional info required.
