1. Goto /Start/Control Panel/Performance and Maintenance/System.
2. Select the Hardware tab and then select Device Manager.
3. Under the 'View' menu select Show Hidden Devices. Double click NT/Apm/Legacy Interface
Node and enable device. De-select show hidden devices again and re-boot.
Now your PC will shutdown automatically just like good old Windows 98.
i been running my system for about a year now... all of the sudden i format my hard drive.. reinstalled windows xp... and since then it doesn't power off. it worked fine before.
i tried the option in device manager but I don't see NT/APM/Legacy Interface Nod even after clicking "view hidden devices". Any other ideas?
i been getting that opinion from alot or sources now. that should be it, since it did shut off automatickly before. i have some bios knowledge, i'll just figure it out.
If you right click Desktop, go to Properties, then to Screen Saver there will be a Power button on the bottom. Click that then there should be a tab that says APC or APM. If you put a tick next to the option given it will enable Automatic Power Management a.k.a automatic shutdown. Most newer motherboards have this enabled so you will not have this option. I used to have this option in my XP but when I updated the BIOS to my board it went away and was enabled automatically.
I know the problem. I had the samething happen. I do know if you mess with the performance settings in the control panel under system that sometimes it will quit working. And will not start working until you put it back to default. This happens when you select it to give the background services more cpu time. Or if your doing it through the x-setup tweak program, selecting short time quotas will have the same effect. so put it back if you changed it and see what happens.
this is a common problem, with different causes and solutions, go here
oh, I didn't read this whole thread, so just in case this wasn't mentioned, try going into Power Options in Control Panel and changing the "When I Press The Power Button" setting to: "shut down
my pc say.. "its now safe to turn off you computer.. instead of shutting off".. but i really dont care any more..
i been kind of busy trying different tweaks.. and slowly learning and diggin in my registry...
i remmeber it did that once i formated it before.. then i formated it again.. and it did not do it.. now after several months maybe a year.. i format again.. and it does it again...
some weird is wrong.. but is really not worth my time.. anyways.. i'll be buying a new motherboard and cpu soon...
