Windows 10: Power button shuts down laptop, instead of waking it up

Since the past 2 weeks, I've been seeing strange behavior in my laptop.When I close the lid, it goes to sleep, but when I press the power button to turn it on, it just shuts down immediately. And doesn't turn on even after pressing power button.Then when I remove the battery/charger and plug it in again, it automatically turns on.I turned off fast-startup from the settings.My mouse and keyboard don't wake my laptop, the setting isn't available.I tried to check on the internet for any solutions, but there are no direct solutionsSystem specs:-OS Name:- Microsoft Windows 10 ProWindows 20H2Versi
