Disabling USB-C power when notebook is powered off not possible

[Raj_05]

Hi @Anonymous,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you. 

It is possible to disable USB-C power delivery when a notebook is powered off, but it depends on the specific hardware and firmware configuration of the notebook and its USB-C ports.

Some notebooks have a setting in their BIOS or UEFI firmware that allows you to disable USB power delivery when the notebook is powered off. If your notebook has this setting, you can access it by entering the BIOS or UEFI setup utility during startup (usually by pressing a key like F2 or Del) and looking for a power management or USB configuration option.

If your notebook does not have this setting in the BIOS or UEFI firmware, it may still be possible to disable USB power delivery by physically disconnecting the USB-C cable from the notebook when it is powered off.

Another option is to use a USB-C hub or docking station that includes a power switch or software-controlled power management feature that can disable power delivery to connected devices when the notebook is powered off.

It's important to note that disabling USB-C power delivery when a notebook is powered off can be useful for preventing devices from charging or drawing power from the notebook's battery when it is not in use. However, it can also prevent devices from charging or being detected by the notebook when it is powered on. Therefore, it's important to weigh the pros and cons of disabling USB-C power delivery for your particular use case.

I hope this helps. 

Take care and have a good day.
