Each time I have to turn the computer off, then restart, put in the suggest passwords, and then get a different error code upon the third try. I have tried your method 22 times on an HP 10P mini laptop with no success.
Please enter some password wrong password 3 times, press ENTER and you should receive a new window stating system disabled and a code similar to this one For HP Mini, should be 10 characters, for others should be 8 characters long.
