I just bought a new Windows 8 Dell Vostro 5470 laptop. I signed in with my Live account, which I use on my main computer everyday.
I upgraded into Windows 8.1, and set up fingerprint authentication as well. I didn't have a problem signing in with it, nor with my 12-character password (which I used today on my PC to log in).
Last night I locked the laptop (from the ctrl+alt+del screen) and left it. By the time I got back, it went into hibernation or something. Meaning to say, it looked turned off. I didn't touch it until today.
When I turn it back on today, I couldn't sign in. Neither the fingerprint wasn't working, nor my password - but then on a closer look, I saw that I couldn't enter more than 9 characters in the password field! Restart didn't work. Reminder - my password is 12 characters long and I used it just the day before.
Disclaimer: this is a brand new laptop, nothing is installed on it. The only things I did with it were Windows Update, upgrade to 8.1, set up fingerprint log-in and surf the web a little bit. I don't mind totally resetting everything, I just don't know how to do it.
Your help is appreciated.
