Jetson Orin Nano 8gb suddenly powers off and refuses to power back on

I have been using Jetson Orin Nano Dev Kit powered via powerbank: Dacota Platinum AM20 40 W powerbank 20 000 mAh, svart - Power.se

It has been working fine for many days now and suddenly stopped working - it powers off and doesn’t power back on (once it powered back on and then after running slam toolbox operations - which I have been running for a while - it powered off again). Attached the images of the setup.

It also doesn’t power on now with the power supply I received together with the board 9v/2.37A (see attached pic)

Pls let me know how to fix this. It has Jetpack 6.2.2 (r36.5)

How did you connect the power bank to the Jetson Orin Nano?

It is connected via this cable: USB-C till DC-kabel 5,5x2,5 mm 15 V | Kjell & Company

(USB-C to DC-cable 5,5x2,5 mm 15 V/3A)

It has been working fine for many days now and suddenly it is powered down and won’t power on even with the power supply

Through the DC jack is the correct way, so you used the right cable.

Does the green power LED near the USB-C port turn on when the AC adapter is connected?

No LED doesn’t turn on - it just blinks and goes off while I connect the AC adapter. When the cable from power bank is connected nothing happens with LED light at all.

Would it be a problem that:
A 40W powerbank at 15V provides only 2.67A. Under heavy mapping load (camera + SLAM + GPU + multiple ROS2 nodes), the Jetson draws 3-4A. This causes under-voltage shutdowns that can damage the carrier board’s power regulation circuit - Use a power bank with Minimum 65W (20V/3.25A) NOT 40W

When the AC adapter is powered and connected to the board, the LED should turn on and stay on. If the LED shuts off right away the AC adapter may be shutting itself down due to a problem/damage on the carrier board or module.

Was the last application that worked running a heavy load on the module?

A power bank with 2.67A limit may not be compatible with the peaks that could occur on the Dev Kit with heavier loads. Powering the Jetson Orin Dev Kits from power banks is not a validated usecase.

I was running: HP60C RGB-D camera + slam toolbox for mapping

Even if it is heavy load, I set the power mode to 25W on jetson using nvpmodel command - in that case 15v/2.67A from power bank should be more than enough right ? The jetson has a power regulation board to take care of such things correct ?

While the continuous current may be compatible, the peak current from a power bank may not be enough and that would be more evident in heavy load usecases.

The power mode for jetson was set to 25W so I dont understand how my 40W powerbank could be a problem. The jetson board had only one peripheral, hp60c RGB-D camera, which was connected to jetson via USB - so all the power was routed through jetson and the total system power should be 25w max.

However due to camera crashes, I had to unplug / re-plug the camera multiple times while the jetson was on - could hot-plugging the USB camera be a cause of problem ?

Although the average power consumption should be ~25W there can be brief peaks of power above what the power bank can support during heavy load cases.
