Hi, I’m trying to diagnose a power fault on our Jetson nano. It powers on, the nvidia logo is shown for a second or so, then it powers off (led light is off) after about 9-10s. I’ve tried various power supplies (we are powering it via USB-C). All the same result. At one point I was able to get it to boot successfully but now it has gone back to powering on/off after 10s. While I was logged in I did note a number of soctherm: OC ALARM 0x00000001 even though the voltage was +5.5V. I’ve reflashed the device a number of times. I’m able to get it to sustain power when running under recovery mode. Any input/suggestions would be appreciated. Thanks ---

Do you have other devices available for testing? Are you sure all these power supplies work stabliy at 5V@4A? ---

We do have other Jetsons. Some work fine, others exhibit the same on/off behaviour. It would be great to pinpoint what’s happening. Yes, we use a regulated power supply, so I’m quite confident that isn’t the problem. It works fine with the other Jetsons. I understand the Jetson is sensitive to voltage fluctuations. ---

Then that sounds like a hardware failure, if only parts of them are failing. ---

Thank you for your input, I’m tending toward the same conclusion. Is there any way to confirm this? Seems odd to have so many failures. Anything I could measure on the board to check for hardware failure? ---

> [@malcolmv](#): > > OC ALARM Are you testing on devkit or custom board? The overcurrent alarm generally comes from heavy workload. You can use a DC supply which can show output current to check if power consumption is too much. ---

Noted. We are using the devkit - amperage is around 1.2-1.4A at 5V, so it’s not even 10W. ---

Can you please try switching to a DC jack? Maybe the USB-C cable you use is not stable, so it cannot reach 5V sometimes. ---

I would if I could…but I don’t understand how that would be possible - please see attached image. There is no DC jack input on the board ![image](https://global.discourse-cdn.com/nvidia/original/4X/d/e/f/def7db36f06f98a8576b7a537be3bed19a64d52a.jpeg) ---

If it’s a custom carrier board, then please ask the vendor who made this. If it’s a DevKit, both A02 and B01 variants come with a DC jack. ---
