    HP Pavilion dv6244ea notebook with Vista Premium.
    If I keep my USB mouse plugged in, the PC won't boot (blank screen).
    So I have to unplug the mouse each time I power the PC on, to plug it in
    again when the boot process is over, and eventually it works fine.
    Upgrading the bios to the latest version had no effect.
    Changing USB port had no effect.
    Changing the mouse had no effect.
    My other USB device (a pen-drive) doesn't cause any such problem.
    Any suggestion will be appreciated.

    In the following reference, click on number 3:

    The #3 link contains several other links addressing what sounds like the
    issue you're talking about. Though the reference talks about prior versions
    of Windows, I think USB problems are not unique to Vista. Take a look to see
    whether you can find something useful.

    Thank you Freddy for your help.
    I read the articles and found some clues that confirm my suspect of a bios
    issue (something related to the legacy USB support or maybe to energy saving
    Unfortunately HP hides the advanced Bios settings, so I am not able to
    change the factory defaults.

    Thanks again and best regards,
    Maria (Vega)
