Unable to Change Power Mode on Jetson (Stuck at 15W Even After Reboot)

Hi everyone,

I am facing an issue with changing the power mode on my Jetson device.

Currently, the system is set to 15W mode, and when I try to switch to any other power mode the change does not take effect.

Additionally, I now get a message indicating that a system reboot is required for the change to apply. However, even after rebooting the system, the power mode remains unchanged at 15W.

Hi @vtol.abhijeet,

Please first check the Jetson Linux Developer Guide power mode section carefully:

The available power modes depend on the Jetson module, JetPack/L4T version, and BSP configuration. Please make sure the power mode you want to use is listed as supported for your exact Jetson module and BSP. If this is for a product design, please also make sure the selected mode is appropriate for your power supply, thermal design, and any applicable regulatory requirements.

Some nvpmodel changes may require reboot when the GPU configuration changes. The settings should take effect after the required reboot if the mode is supported for your setup.

If you have followed the document and the problem still occurs, please share the following information:

  1. The exact Jetson module/dev kit you are using.
  2. The carrier board, if this is not an NVIDIA developer kit.
  3. Which power mode you are trying to switch to.
  4. The exact command you used to change the power mode and the full terminal output.

Please also share the full output of:

cat /etc/nv_tegra_release
dpkg -l | grep nvidia-l4t-core
cat /etc/nv_boot_control.conf
sudo /usr/sbin/nvpmodel -q --verbose

Hope this helps!

Hi,

Thanks for your response.

  1. I am using the Jetson Orin Nano Official Developer Kit.

  2. I am trying to switch the power mode to MAXN (Super mode).

Previously, I was able to change the power mode using the Power GUI (top-right corner panel), and it worked correctly. However, now the mode is not changing anymore—neither through the GUI nor via command line.

Even after selecting a different mode, the system prompts for a reboot, but after rebooting, the power mode remains unchanged.

Please let me know if any additional logs or details are required for debugging.

Hi,

The available power modes depend on the flashed Jetson configuration, not only the module name. Per the Jetson Linux Developer Guide, MAXN_SUPER is available only when flashing with the jetson-orin-nano-devkit-super or jetson-orin-nano-devkit-super-maxn configuration.

Please review the official power mode documentation carefully and confirm that your current flashed configuration supports MAXN_SUPER:

If you have already checked the document and confirmed that your setup should support MAXN_SUPER, but the mode still cannot be applied, please provide the missing information requested earlier so we can check your actual system configuration.

You provided the first two command outputs, but the following two outputs are still needed:

cat /etc/nv_boot_control.conf
sudo /usr/sbin/nvpmodel -q --verbose

Please also share the exact command you used to switch the power mode and the full terminal output, including whether you entered YES or yes when the reboot prompt appeared.

Thanks.
