Turn off USB power when laptop off
|
On my HP ProBook 445 G7 I disabled quick boot in Windows, wake up on LAN and USB are also disabled in BIOS but the battery looses about 14% a week when it's shut down. Show When I connect my phone to the USB C port it starts charging when the laptop is off. It doesn't happen with USB A ports. I saw posts for other laptops having a BIOS option to turn USB charging off but I cannot find it in my BIOS. How do I disable the USB C charging while the laptop is off? asked May 22 at 13:02

I have that kind of setup on my Lenovo Laptop. Two solutions: (A) Turn it OFF in BIOS. (B) More preferable: Do not use the port when the machine is turned off unless it is plugged in. I use Battery Threshold, so the very best solution is to use this port when the machine is running. This works best for me. Note that I use Battery Threshold to allow me to worked plugged in all the time. But if I turn OFF, then I unplug the machine. It is also possible your battery may lose charge when idle, so consider that possibility. answered May 22 at 13:07
