ACPI Power management-shut down option changed
James
BIOS v6.0
I have an issue where upon choosing Shut down the PC merely gives a
message stating, "It is now safe to turn off your system" I am aware
the known remedy for this is to reformat and choose this option on
reloading.
Originally the machine was loaded with windows 2000 and shut down as
desired (upgraded to windows XP recently). Some where along the line
the power management settings had changed. A friend mentioned to me
that a service pack might have done some thing. Can any one offer a
solution other than reformatting?

There's newer BIOS:

If ACPI isn't working properly, install APM.
Here's the whole APM/ACPI story:
*BIOS*
Your machine will either use APM or ACPI to handle turning it off. Both have
BIOS settings that need to be enabled, and drivers that need to be installed
(re-installed if the system turned the capability off). Make sure "Legacy
Plug and Play" is off or disabled in the BIOS.
*APM*
If you have an old (or non-ACPI compliant) machine, it will use APM (Advanced
Power Management). In the control panel, Power Options... see if you have an
APM tab >> turn it on. (You can install APM with Add Hardware. See next
paragraph.)
Run "Add Hardware" in the Control Panel. After it does all of its scanning
stuff, click Next (leave the Radio Button set to "already installed
hardware"), select "Add a new hardware device" tell it to "Install the
hardware that I manually select from a list." "NT/APM Legacy support" should
be near the middle of the list.
*ACPI*
If you have a new machine, it will use ACPI (Advanced Configuration and Power
Interface). In Device Manager see if your computer is an ACPI Uniprocessor PC
(or dual... whatever you have). Try reinstalling its driver, then look under
System devices for Microsoft ACPI compliant System >> reinstall its driver.
(You can install ACPI by updating the "computer" driver. See next paragraph.)
When the Hardware Update Wizard starts, click on "Install from a list or
specific location (Advanced)" then Next. On the next menu, click "Don't
search. I will choose the driver to install" then Next. You should find the
ACPI Uniprocessor PC listed on the next screen. If it isn't there, you will
have to do a reinstall and press F5 at the start (see next paragraph).
Sometimes, ACPI will require a reinstall to get it sorted out correctly. At
the start of the installation you will see a request to hit F6 if you need to
install additional SCSI Drivers; hit F5 instead. Later, you will be asked to
identify what kind of PC you have, scroll up in the window near the bottom to
the ACPI types and select yours (commonly: ACPI Uniprocessor PC). Remember to
reinstall the XP Updates, especially SP1, following a reinstallation of the XP
OS.
*Shared IRQ Conflict Problems*
Sometimes you will have IRQ Conflicts that cannot be resolved. With an ACPI
Compliant PC you can affect IRQ usage by moving the boards to different PCI
Slots and that may resolve the problem. If you can't resolve IRQ Conflicts
that way, remove ACPI by changing "Computer" in Device Management to "Standard
PC" and install APM to control the shutdown. With APM instead of ACPI you can
control most IRQ assignments/usage.
