The Enter power on password comes up when I turn on computer, I don't know the password and after some attempts a message saying system disabled (13535).
We can't help with unknown or forgotten passwords as we have have no way of knowing if you are the authorised or legal owner/user of that computer.
You either have to enter the correct password or you'll have to take the laptop to an HP repair shop to have the password removed. And you'll need to provide documentation to prove you're the legal owner or they may not be willing to work on it. There is no workaround.
