Its been some time, and I can tell you guys I really did read all of the documents posted about the acpi and apm problem.
I have posten my problem before in great extent and will keep it short this time
My computer is ACPI complient, but Windows XP doesnt like it and crashes my computer occasionally with the well known errors. I then decided to follow up all your advice and reinstall with the Hall for 'standard pc'. I did so with good results. My computer runs now and it doesnt crash under XP. However I don;t have an APM tab under power options. Since this is a notebook it would be nice to have one. The documents I read suggest I should enable power management in the bios, but I disabled it because of your suggestions.
What do I have to do to make the APM tab show up in Win XP? Should I enable it in the bios anyway?
