    I don not know if it will work with your system but sometimes if you remove the CMOS battery for a couple of minutes that will do the trick.

    Hope this helps!!!

    You have to first enter the bios with your administrator password, and then there is an option to change passwords. If you don't know that password, you won't be able to change it. Laptop passwords which aren't known by the user can only be changed by the manufacturer or service center. You'll have to call them and they will require proof of ownership from you. This is a security feature which prevents thiefs from using a laptop or industry spies from getting info from the harddisks.

    clearing your CMOS by removing the battery in the motherboard is a very quick answer.

    HP nc6220 is a notebook and no you can't remove the CMOS battery as the password is stored in an EPROM chip or worst into TPM (Trusted Platform Module). I think the nc6220 uses TPM1.2.

    Well as commented by rindi, you may have to send it to HP service centre.

    I know they can't crack the password on an IBM Thinkpad T43 series with TPM chip. They have to replace the entire motherboard and the harddisk if the hard disk also is TPM password protected.

    You will have to remove the cmos batterry.....remove the power supply from your ur case.....the batterry...... and hold down the power button for about 10 secs.......this will also remove all the static charges that r stored inside.......

    if you have a jumper reset option on the motherboard......that will definitely flash the bios to its defaults.....but you will have to check the motherboard manual for your comp for the "how to's "

    Good Luck!
