So, I have a lenovo yoga 11e laptop administrated by the school. I wanted to reset bios and have access to it. It does not have a supervisor password set, just a power-on password. So I took the necessary steps to perform a cmos reset. But, when I plug in the AC cable and waited the computer to boot, it just turns on with a completely black screen and then it shuts off and it will repeat itsel over and over again achieving nothing. Is there something that I did wrong? Do I have to wait till the cmos clears at some given time and then plug in the AC cable? Need help?

Unfortunatly i have the same school laptop and i tried reseting the bios password so far no luck. removing the cmos battery wont work
because the password is saved in the moderboard and use stuff like killcmos will break your laptop cause the password isnt saved in the cmos. so i will reply this message if i found something
