    Hi

    I just received my new Dell U2412M monitor connected via DP that goes together with my old 22" Dell connected via VGA.
    The problem I'm facing is that laptop does not boot - it starts and immediately enters a mode where 3 locks buttons light up and nothing happens.
    only when I disconnect the DP connector it starts and then I can hook it up back again and everything works fine.

    I've updated the BIOS to latest version - still no go.
    I have the integrated Intel graphics.

    Does anyone know how to solve such issue?

    So it doesn't boot even if you just have the monitor on DP connected? What if you connect a different monitor with DP?
