I am trying to find out the lowest idle mode power of the Xavier. The lowest, I seem to go down is 5 watts. Here is the setup. Wondering if anyone can help me identify where the power “loss” is happening.
Installed Jetpack 4.4 on the Xavier dev kit (not NX).
Just OS flash. No CUDA, AI libs etc.
No attached sata, keyboard devices. Display is unplugged. Only ethernet is plugged in for ssh. Disabling the eth0 doesn’t help with power reduction.
nvpmodel is set to 1
No user applications are running. Standard boot after flashing Jetpack 4.4
In this configuration, the usage is about 5 watts.
However, the onboard power sensors sense the use of of only about 2 watts. There is no camera, M.2 etc. Basic out of the box dev kit.
Any thoughts, why and where the power is being used?
