Recently i had a power failure within the property, unfortunately, I was not present at the time so am not aware if it was a long or short-term failure but whatever happened my Argon one V3 M2 NVMe PCIE no longer works…i cannot even power it up?
If I use an alternative to Argon, the Raspberry Pi 5 and SSD work perfectly. The Raspberry Pi software configuration appears to be how I expected it to be?
Any suggestions, please? or is this destined for the trash?
Thanks
During power outages, sometimes also a spike with overvoltage is possible from the power socket and can damage connected electronic equipments.
After such kind of overvoltage, maybe you should inspect the lines at the pcb starting from USB power connector if you can locate some tracing of smoked contacts or exploded chip case.
According to appendix J of the PDF manual, the Argon ONE V3 has the option to make a simple function check without the RPi5 connected. Do you have already checked?
You also skimmed with details if you reused the same power supply or what we should assume as your “alternative”. 
The alternative power supply was working on another RPI.
The power supply from the RPI in the Argon case works fine for powering another RPI.
I knew about the Argon test facility but unfortunately forgot about it before I disassembled the unit.
In summary, at this point in time, the RPI, SDD, and Power supply I was using still work fine.
Thanks for your response.
OK, So i take it the unit i have is trashed…
You doesn’t wrote about the result of the hardware self test. Was it failing too?
I’m asking, because some printed circuit boards had in the past “only” bad or not existing soldering points. Some in the near of the “Always ON” jumper bridge. Mostly this and Argon One v3 Not Powering On - #3 by GraphicW was the reason for not functioning at power up. There was also a case, where the power button itself was damaged/not connected and the Argon ONE case was starting only if the jumper was set to “Always ON” mode.
If the self test is working, I would inspect the pcb for such kind of issues. If the self test is failing, try another power supply (for the unlikely case that only the Power Delivery negotiation fails) if you have or throw the pcb into trash …
Self test fails and no other visual issues exist, I don’t think I will be purchasing more from Argon as their Warranty does not appear to be that great either…
