Expected behavior

Power up after applying USB power.

Actual behavior (suspected bug)

Not powering up. Before malfunction was functioning OK - running the chatGPT assistant for Home Assistant for >1 month. Today I noticed:

• Blank screen
• No green LED
• V USB = 5V, I USB = 0,05-0,12A
• Yellow Mute MIC LED can be switched on/off with its button
• Device not seen by PC
• Tried 3 different USB cables
• Tried powering via dock
• Tried BOOT + Reset buttons
• MCU_VDD test pad = 0,05V
• Other voltages seem OK
• No visible damage

As I understand, either the DC-DC converter or the MCU is kaput. I searched for warranty claim options, with no luck.

Steps to reproduce the behavior

1. Apply USB power to the unit or to the dock
