Swift SF314-43 fans still operating in sleep mode

Hi,

I've posted before about how this laptop has a weird power management issue. It won't enter sleep while plugged in. It's been like this since I got it.

So, I don't know if this new problem is related to that, but for the first time I left the laptop in sleep mode in hours, only to find when I opened it that the laptop's battery was at almost zero. It turns out that even in sleep mode the laptop fans are running continuously. Thus, draining the battery. I can actually hear them running while the lid is closed and it's in 'sleep mode'.

I ran Windows event logger and found this error - 'usb device draining system power while machine idle'. I presume that this is related to the problem?

I've done every step I can google to find a fix. I've put the laptop cooling to passive from active and I went to the BIOS settings but could not find anything related to this problem there. Windows and drivers are up to date etc.

Is there a way to fix this? I'm sick of issues with this laptop since I bought it.

I'm running Windows 10 on this laptop.

Thanks.

Yes, that makes sense in regards to a USB device pulling power when sleeping. Do you have anything actually plugged in to a port, or is it one of the builtin devices like WiFi, Bluetooth, camera, etc.? The USB 3 port on the left side (blue) supports offline charging, so provides power to whatever is plugged in, even when the laptop is off.
