Motherbord without CMOS

[Benjamin_71]

For a high security laptop i need a bios without a cmos battery to disable reseting the bios. I heared this technology exists but I have bo idea what it is called. Or any other technology made it impossible to reset the bios.

If it's for security then you are most likely worried about someone trying to reset a bios password. This is a non issues on the vast majority of modern laptops as the password is saved in NVRAM which is not affected by removing the cmos battery or resetting bios defaults. Most either require a special reset procedure only the manufacture knows or there is not way to reset it and if forgotten the motherboard is a brick. Same goes for HDD/SSD passwords that are stored on the drive and not in bios.
