...Is it True That a BIOS password can be deleted...

Usually.

...If yes How to prevent this....

Write your own BIOS with a password that only you know:
BIOS Mods
It is not easy.

You would have to test your motherboard yourself by setting a password then removing the battery and start up to see if the password is gone. Make sure you power off before removing the battery. I have a Dell laptop which will not reset doing that.
If it does reset, you'd have to put the machine in a locked case to keep someone else from doing it.

Don't let people have physical access to your PC (i.e. lock it up somewhere).

Another option is to replace the standard case screws with unusual ones (e.g. Torx heads instead of Phillips head)

On a desktop removing the CMOS battery will reset any BIOS passwords. There isn't anything you can do about that. You would need some other method to maintain security.

But on a laptop BIOS passwords are not stored in the CMOS so removing the battery will do nothing. Don't ever forget a BIOS password on a laptop.

Yes, not just about a week or so back someone had the same issue and pulling the battery did nothing.

On a laptop.

Hi vivek pecqurel,

In addition to what everyone said I would like to add:

To reset the password for a laptop you need to contact us. After verifying the ownership of the system only we can reset the BIOS password for our customers.

Otherwise, reseating CMOS battery would not reset the password. We only reset BIOS password after confirming system owner details only.

I hope you find this information useful. If you have any more queries feel free to contact us.

Good computer security always has multiple layers. The first level is physical security. As far as is practical you would not allow an untrusted individual sufficient access to your computer to remove the CMOS battery. That level of physical access will compromise many other aspects of security, not just resetting a BIOS password.

@vivek-pecqurel,
Removing a laptops battery can NOT be used to reset/clear a BIOS password once it has been set. The process can be done, ... but only with the use of very specifically designed scripting/coding. If you don't presently need your BIOS password cleared, your question is answered. Be sure to write down and save the BIOS password before setting it.

The same answer goes for people who chose to password protect their hard drives. My recommendation is to NEVER password protect your hard drive if there's even the remotes chance the password will be lost or forgotten. When you password protect a hard drive, The password itself is stored on that specific hard drive (instead of in the BIOS). ALL data stored on a password protected hard drive becomes encrypted. The encryption algorithm is entirely dependent on the password used to protect the drive. If you lose/forget the password, you lose all data on the hard drive. Lose the password and you've just created a new desktop paperweight. There is, however, a very small chance of recovering the hard IF you know someone with access to very specific coding that can work to clear the password on a small number of drives.
