Good evening and thanks for using JustAnswer
There are 3 ways to resolve this issue.
1. Contact HP and provide proof of ownership. They will provide you with a method to over-ride the CMOS password.
2. If you are comfortable dis-assembling your laptop, you can remove the cover and find the CMOS battery. You will need to disconnect this battery (keep in mind that a lot of laptop batteries are soldered on), leave it disconnected for a minute, then re connect.
3. Download a tool that will allow you remove the password. Keep in mind that this tool is not warranted by myself, JustAnswer, nor the company that provides it. It is reported to work and has several positive reviews, however. For that tool, click here.
