Hello,
I've an HP Probook 445 G7 which I've barely used, I've bought it new in March 2022. It's sitting off most of the time.
I have battery care enabled in BIOS.
It's loosing about 10-15 percent of battery charge per week while off.
I've disabled fast startup in Windows but it didn't help.
I've also disabled USB devices in BIOS and it didn't help either (I'm not sure what it does because all the USB devices are still working as usual after this).
I've noticed that I can charge other devices like my phone via the USB-C port on the laptop while it's off. I'm not sure if it's causing the battery drain, but I've not found a BIOS option to disable this (I saw that some laptops have this option, but mine apparently doesn't).
Is there a way to fix this so that the battery doesn't drain so fast when off? (I've heard that the normal figure for other laptops is -2% per week while off)
