Battery drain when laptop is completely powered off (Fast Startup issue?)

Hi all, I’m having a severe battery issue with my Asus laptop. If I charge it to 100%, use the Windows Start Menu to click "Shut Down," close the lid, and leave it overnight, the next morning the battery is completely dead at 0%. It's literally draining while it's turned off. I heard this might be related to a feature called "Fast Startup." How do I check if that's the culprit?

    I don't think the "Fast Startup" is the reasonreason.Factly,i got the same problem when i turn off my XiaoMi laptop night(battrry100%),in morning the battery 70%,but not 100.I still don't solve this problem,but if you want to check if that's the culpri,you can open the control panel then find the power，there will be a button"change power seeting",then open it,there will be a "fast startup",you can turn it off.

    If you turn"fast startup"off,the problem are not be solved,i think this problem might be the hardware problem.
