Greetings! I recently received a dinosaur of a pc. It is a AMD K6. It had WIN98 installed, and even then, it had to manually shut it down, So, Brilliant me, I installed XP Pro Corp.(to totally tax every resource it had). Well, I am unable to get it to shutdown automatically. I played with the power options/APM, and played with disable and enable "Legacy Support". I also went into the regedit, and modified the winlogon "POWERDOWNAFTERSHUTDOWN". All so far either continues the PC to Restart at shutdown or " It is now safe to turn off your...".Then you can push the power button off. It is so simple to push the button, I just feel defeated.I possibly think the BIOS needs a good update?! Any ideas would be much appreciated. Thank You -ez

Many older PCs had an ON/OFF switch, which Im sure yours has. This switch cannot be auto-shutdown, because of the physical switch needing to be pressed. Rich Gu P4 3.2 / 1 GB PC3200 Intel MOBO self built

Rich, your answer doesn't make much sense, even though in a sense, you are probably correct in this case. All my newer machines which are capable of auto shutdown still have a "physical switch." In the case of the older machines which do NOT support autoshutdown, the power switch is normally a "click on/click off" switch, just like most any lightswitch. One way, it is CLOSED, or on, push again, it is OPEN, or off. In the case of newer hardware which DOES support autoshutdown, the power switch is a "momentary" switch, meaning normally OPEN, momentary ON (when held in). These work, in other words, just like a doorbell switch. Without checking these switches with a meter or test light, it would actually be impossible to tell in many cases, unless you "knew" what it was hooked up to. One thing you might check, before you give up on this problem, is dig around in the bios menus. Post or look up the motherboard model. If this is an ATX board, as opposed to an AT board, it just might support autoshutdown.

Look at the Power supply connection to the Mother board AT or ATX ? If it is a ATX single 20 Pin plug 2 rows of 10, It should shud down auto. If AT 2 plugs it will not auto shutdown..

Another way to tell the difference. AT machines do not have the close group of external connections (audio, LAN, USB, PS2, etc) on the back. All the AT connections are on cards. Sorry, I do not check for private messages
