My dad's hibernation doesn't work properly! Why? ???

[Jonas Wauters]

It's my dad's computer hibernation not my dad himself although I would love that!
If my dad's computer "restarts" after I used the hibernation way to shutdown his PC I always get the welcome screen.
Why?
I don't want it.
How can I prevent the computer from doing this?
I know I have a lot of questions sorry for that.
Computer info:
Windows XP professional SP2
256MB RAM
1.5GHz mono core processor.

Thanks in advance Jonas.

Is your Dad going to be pleased your trying to make adjustents on his computer?

[Jonas Wauters]

Yes afcourse he asked me to.
Otherwise I wouldn't do that.

This is a very minor issue, isn't it?

[Jonas Wauters]

Yes but it is ignoring.
And I would like to know how I can prevent it.
You don't have to answer if you find this an irrelevant question.
