It's not looking good. Your kids had to type it twice to be able to set one. If you can't get them to remember it you might have some work cut out for you.

Read the information on the site I provided above. Sometimes you luck out and it's a simple jumper setting to clear a BIOS password. Sometimes you are looking at onboard memory that stores the password. From what I have read about it so far by googling it.

The RTC battery is on the underside of the system board, and you will need to totally disassemble the laptop to get at it.

They talk of a video guide from HP showing you the steps to do this, but I was unable to find it as it has likely been removed.
Click on the -->Real Time Clock Battery<-- 3rd from the bottom of the left side column.
Use the link below to get some online chat help from HP.

Good luck...hopefully this helped out some.
