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.
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?

How do I disable the USB-C charging while the laptop is off?
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.

Keyboard or mouse not working after your PC wake up from sleep? When you’re charging your phone through an USB port, putting your PC into sleep mode will turn off the power to USB ports, and your phone will stop charging. In this tutorial we’ll show you 2 methods to set Windows to power on or off USB devices in sleep mode.
Method 1: Enable / Disable Power Saving on USB Ports
- Press the Windows key + R to open the Run box. Type devmgmt.msc and press Enter.
- When the Device Manager window opens, expand the Universal Serial Bus controllers branch, then
right-click the USB Root Hub device and select Properties.
- Click the Power Management tab. If you want USB ports to keep supplying power in sleep mode, just uncheck “Allow the computer to turn off this device to save power“. Or check it to let Windows turn off USB ports to save power.
- Repeat steps 3 and 4 for all of the USB Root Hubs on the computer.
Note: Windows will clear the check box “Allow the computer to turn off this device to save power” when the device is unplugged from the USB port or the PC is restarted. To keep this from happening, use the method below to disable USB selective suspend setting.
Method 2: Enable / Disable USB Selective Suspend Setting
- Press the Windows key + R to open the Run box. Type powercfg.cpl and press Enter.
- When the Power Options window opens, click the Change plan settings link to the right of your current power plan.
- Click the “Change advanced power settings” link.
- Expand the “USB settings” and then expand “USB Selective suspend setting“. Set
it to Disabled if you want to stop Windows from powering down any connected USB devices.
- Click Apply to save your changes.
