Get the manual for the mainboard in your laptop and check if the vendor provided a procedure for resetting the BIOS password. If not, try removing the CMOS battery (if the mainboard has a removable one) for a couple seconds. That should also reset the BIOS. The location of the battery should be described in the manual.

You don't enable it from the command line. It must be enabled from the BIOS.

If you forgot your BIOS password, work on that problem first.
