at least with win nt4, you have an entry in the registry (sorry, i don't remember which one), where you can disable the atx power down feature on shutdown. so the pc is still powered after shutdown. then you can disconnect and reconnect power, and the pc will boot again, without pressing power button. i use this for a pc that is controlled from a central switchboard, when operation is required. tino Jim Main Gesendet von: pic microcontroller discussion list 19.06.02 18:04 Bitte antworten an pic microcontroller discussion list An: PICLIST@MITVMA.MIT.EDU Kopie: Thema: [EE]: Cycling power remotely on an ATX PC I have an application at a remote site where I send data over a WAN to a PC, which then talks to a PIC interface controlling various bits of equipment. Since PC's occasionally crash, I've put in a telephone-operated switch on the power feed to the PC. Problem is, I've just realised that cycling the power in this way means the PC won't boot up (since the front power button needs to be cycled after a mains reset). Any suggestions? I'm thinking maybe of another pic that delays a bit then closes a relay contact across the power jumper on the motherboard.... -- http://www.piclist.com#nomail Going offline?
