648 Max-L * Shuttdown in XP

Question

When I shuttdown my computer it prompts me that it is safe to shuttdown.
I want it to shuttdown by itself. Usually there is a setting for this in BIOS under power management but I cant find it.
Do I need to change somethign in the BIOS or XP?

Answer 1

Found this on the web. Don't know if it will help.
ACPI enabled?
I had this problem under linux, it was detecting the P4 as a dual CPU. I know I've had it do this under Win95 or 98, but can't for the life of me, remember what caused it.
Edited: I know there is also a registry setting for putting a "Powerdown after Shutdown" option in the shutdown menu. Search for "PowerdownafterShutdown" with regedit and change value to 1. I would only try that as an absolute last resort, mainly because I think it would just shutdown and reboot the computer. Also, depending on what version of BIOS you have, you may have a "Plug and Play aware O/S" option. Set it to yes. Don't know if that will fix it, but it should be set to yes for XP.
"Powerdown Issues
"Powerdown issues" are quite distinctive from "shutdown issues." I define a shutdown problem as one wherein Windows doesn't make it at least to the "OK to shut off your computer" screen. If Windows gets that far, or farther, then it has shut down correctly. However, the computer may not powerdown correctly after that. This is a different problem, and I encourage people reporting these issues to make a clear distinction in their labeling.
When Windows XP won't powerdown automatically, the APM/NT Legacy Power Node may not be enabled. To enable this, right-click on the My Computer icon, click Properties | Hardware | Device Manager | View. Check the box labeled "Show Hidden Devices." If it's available on your computer, there will be a red X on the APM/NT Legacy Node. Try enabling it and see if this resolves the powerdown problem. (Tip from Terri Stratton.)
This should resolve the powerdown issue in most cases. However, other factors can sometimes interfere with correct powerdown functioning. In that case, consider the following tips:
" If you changing the default power settings in the BIOS, it can lead to a powerdown problem. Restoring all BIOS power settings to default will likely fix it. (Tip from Kelly Theriot)
" Correspondent "Snake" reported that, when the above didn't work for him, he restored powerdown functioning by disabling his CD-ROM's AutoRun feature. The fastest way to do this is with the "Disable AutoRun" Registry patch which you can download here."
