Please edit your post and delete your serial number if the moderators haven't done so for you. Posting serial numbers is not allowed as it breaches the forum rule on posting personally identifying information.


You will need to contact HP Support in your country. Business notebooks typically have stronger security than consumer notebooks and need a custom SMC.bin file to remove the password. These files are date and time sensitive, so do not be tempted to remove the BIOS battery; that will not clear the password but will likely make the SMC.bin unlock fail.
