SATA HAT dead, buzzing and lights flickering

My SATA hat has stopped working after about a week of use.
The Pi won’t boot ( not even fan spin up ) with the hat attached.
It’s making a strange buzzing noise and the lights flicker on/off.

I assume my board is faulty? Anyone else had similar?

Video of the issue. Turn the sound up quite loud to hear the noise it’s making.

Testing

  • Different power supply - no power on
  • Removed the drives from the hat - no power on
  • Remove the hat - powers on and boots
  • Remove ribbon cable with hat still attached - no power on
  • Power hat with 12vdc not connected to a Pi - buzzing and lights flashing

State it was in when it stopped working

  • Raspbian with MediaVault installed
  • 4x SSDs, just some old drives for testing
  • I had anacron logs come through about 45mins before it went down and started buzzing, but the system is mostly idle as I had not purchased the new drives for it.

The source of the sound appears to be a component labeled with ALTP 728?
I could be reading it wrong, but I’m not seeing any docs for it.


I’m sorry you have a problem.
Please contact the store where you purchased it for replacement.

We’d like you to send the broken one back so we can do a failure analysis.
