Installation attempt results in shutdown

[David Jonsson]

Hello!

I am trying to install FreeBSD on my laptop (HP/Compaq nx9105), but as
soon as I choose an alternative on the first menu that appears my
computer shuts down. It happened both with 5.1 and 5.2.1, and it
happens no matter which alternative I choose. I really have no clue
what to do. I have tried asking around, but most people told me to
send a mail to this adress, so I would be really happy if you have an
answer for me :)

Thanks in advance
