acpi and hardware profiles

[Guest]

My laptop currently has ACPI enabled. If i were to create a new hardware
profile, could I have ACPI disabled (standard pc instead) under just that
profile? Or, if i made a restore point and then disabled ACPI and my computer
stopped working because of it, would that restore point revert my machine
back to ACPI? The reason i am asking is because i want to test some things
with ACPI disabled, but if i screw something up by switching to Standard PC i
would like to be able to go back and change it. Anyone know anything about
this?

Isn't ACPI a motherboard/bios enabled setting that loads way before XP loads??
XP just sees whether its enabled or not and installs accordingly.
It is my understanding that if you change the setting(BIOS) you will need to
reinstall or at least run a "repair" installation to correct things.

No. Does not work that way. The HAL is one of the major underlying bricks
that the rest of the installation depends on.

I would skip the restore point idea too. The hal.dll and computer type are
at a deeper level of system management than system restore.

One thing you might try is hardware profiles. Don't recommend changing the
basic computer type but you could disable devices not needed under changing
circumstances. An article that you may find interesting:
