I have a PC with Win2K and an ATX (AMD/ASUS motherboard) and it powers down when I shut down -- but I don't want that! I shut everything off -- montors, PC, speakers -- using a power bar. How do I disable this feature? Also, the ATX won't come up when I turn the power bar on -- I have to press the switch on the front of the PC. If you can help with that I'd be grateful.

If i remember correctly . . . . go into the bios and disable power management or something along those lines. Its defiantly something in the bios im sure of it, i had the same problem but in reverse cured it straight away by changing something in the bios, it was so long ago now thou so can remember what.

Did you ever found a solution to your requirement? I am in the similar situation as you described. The only difference is that I am using XP instead of W2K. I tried disabling the power management in the BIOS like Nick suggested but shuting down windows continues to power off the PC.

to answer jim's question about having the computer come on as soon as power is given 
to it (the switch on the power bar being pressed) this is a BIOS issue. on 2 of my 
computers (from a few years ago) i found the setting but if i remember correctly 
it's not on my newest computer (7 months old) but just look and see if you have it. 
it should be something like What to do when AC power is restored, and you can have 
it 1. stay off, 2. turn on, or 3. go to the last state it was in when power was removed. 
for example if you have no power bar (or simply never use the switch on it) and then 
its late one night and the computer's off and then there's a power outage from a 
storm or whatever, and power is removed from the computer for a little while, and 
then when the blackout is over power is restored, you DON'T want your computer to 
come on right? so option 2 would be no good. however if you use a switch of some 
sort (power bar, etc) and when the computer's not in use the switch is always off, 
then option 2 is perfect for you so when power is restored (switch goes on) the computer 
starts right up and you don't need to reach down to the button on the tower.

as for the computer powering down as soon as you shut it down....why is that bad? 
just turn off the power bar as soon as it's all powered down and you'll be fine.

Well what you could do to disable the auto shut down features, also this fixes alot of irq sharing and puts things on their own irqs for the most part, would be to go into your hardware properties screen drop down the computer one and then on ACPI compliant PC right click and update driver change that to Standard PC and it will not share as much irq's and no special power features will be used.

It may be possible to prevent power down when you shutdown windows but the problem of turning the power off and having the PC come alive when its reenergized can not be fixed in bios. ( not even if you edit the bios firmware via Hex editor) Being an ATX computer your power supply is turned on and off by a Softpower circuit on the Motherboard. This is basically a micro relay system controlled by the momentary contact of the power switch connected to the "Front Panel Header" therefore with the power off to the PS the relay deenergizes and can only be reenergized by pushing the Power Button. The only way to disable the Soft power function is to permanantly jump the Power On switch contacts on this header, your power switch will no longer work but your computer will work as you want it to.( off/on by the switch on power strip) Caution: If you jump the wrong connections on the FPH you will cause serious damage to your Motherboard.

Here is the solution whether you want it to power down automatically or not you disable or enable the feature below. This works in most versions of windows. 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). Or, to check the other side of the APM/ACPI coin, open the Power Options applet in Control Panel. If there is an APM tab, make sure the “Enable Advanced Power Management Support” box is checked. (MSKB 313290)

You could try changing the following registry value. Go to Start-> Run ->regedit. Browse to the following key and change the value shown. [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon] "PowerDownAfterShutdown"="0"

I've been recently having problems with my XP home machine all of a sudden simply 
shutting off the power. This after the computer has been running 10 min reguardless 
if I've been using the mouse etc. I don't even get any error messages from Windows 
of a "Crital Error" then restarting.

To try and troubleshoot I've did the following.
(1) Checked that the main case and CPU fans are running.
(2) Started the PC and let it set at BIOS setup for 30 min.
(3) Started the PC and with a blank formatted in drive A: and let it set 30 min.

No power off during (2) and (3) so this rules out the problem being in hardware or 
BIOS Correct?

(4) Started the PC and let it set at the logon screen. Power just shut off in 10 
min all by itself. This would seem to reflect a problem in Windows Core install would 
it not?

I checked BIOS and Windows power management before I did any testing and the only 
thing set to turn off is the monitor after 30 min in Windows PM.

Is there a way via a Reg patch to overright all of the PM settings back to Factory 
defaults?
Or is this a known issue there is already a fix for?

I remember a tool in Windows that could check all your key files for corruption but 
don't remember where it is. That may be my problem also.

Here is my case:

My W2k fails to POWERDOWN after SHUTDOWN clicked or PWR button pressed directly. 
This problem happened since I reinstalled (not new installation) W2k due to booting 
failure from swapping motherboard.  

I am sure this can't be hardware issue because I did W2k New installation on another 
harddrive and it works just fine. Shutdown and then Powerdown. 

I've done all possible solutions I can find including changing BIOS setting, Removing 
[ACPI Fixed Feature Button], [Microsoft ACPI-Compliant System],...etc. And problem 
just remains.

Any help?
