Why Windows 8 can not require bios password ?

In Windows7, setup bios. if clicking "hibernate", and then start PC, the PC will require bios password.  But in Windows8, it directly go to windows login password. Any one can give some suggestion to let the windows 8 have bios required ? Thank you

About the only reason I know for this is if there is a power on / hard drive password on one and not the other.

My Windows 8.1 Pro laptop has both power on and hard drive password. If I suspend for more than about 3 hours, it will ask for the power on password and then exit suspend just fine. It would work the same for hibernate.

Power on password is always set in the BIOS independent of operating system.

it has to be done with a BIOS option, nothing to do with Windows for both 7 and 8. i would guess you did change some settings in BIOS after switching 7 to 8.

please double check your BIOS settings again.

Thank you for your fast reply. I just realize my bios password that I just setup cannot work in my Win 8. It just work one time when I set it up. And then it does not work again. I think something wrong. In Bios, I configured administrator and user password. Why Bios password does not work ?

first try resetting the BIOS to its default settings, which has no password for both administrator and regular users.

Strange outcome. Can you update the BIOS with a new version?  Then remove all passwords as per the above post. Then shut the computer all the way off. Start up and set a new password.

I have not had any BIOS forget that I set a password.
