compaq Presario v1000
It appears the Compaq V1000 is not a model you can reset the password with the usual tricks of removing the battery or such.
Contact HP to find out what method to use. May require you to supply some code number from a screen and HP will supply a reset password. This reset password is not something you find on the internet. It's something more so you are stuck working with HP.
password recovery is very difficult. so you need to do remove mother board small battery then insert it again.
