I have a hp 2000-2104tu laptop. When I turn on the machine the HP diagnostic tool starts automatically, without pressing anything. Once I exit from there windows starts, and at the password prompt some character appears repeatedly, and I cannot type the password. And that is the only user account on my laptop. I think disabling the internal keyboard might help. Any ideas?
