Product: HP ZBook Firefly 14 inch G8 Mobile Workstation PC (275V5AV)
Operating System: Microsoft Windows 11

Hello everyone! I have battery drain after regular shut down. I disabled fast boot in bios and disabled fast startup in Windows 11.

All drivers&bios is up to date.

When is notebook turned off (without ac charger plugged in), I hear from the bottom cover (air mesh) of the Zbook some coil whine sound or something similar. When I turn off the Zbook (100%battery) for some days (5-6) there is +-60% of battery left. 

It is normal (coil sound when is notebook turn off and battery drain)?
