What happens if: 1) power fails 2) NUT detects this and halts the machine 3) power returns before batteries are exhausted Will the machine sit forever waiting for someone to "Press any key to reboot" ? -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of James Long Sent: Thursday, March 09, 2006 12:46 PM To: freebsd-questions@freebsd.org; Ion-Mihai Tetcu; Peter Subject: Re: coming back up after power failure (UPS) Pre Y2K PC's had mechanical power on button which stayed in the "on position" no matter what was happening with the line power. Those pcs are what UPS units were first designed for, so after the UPS does normal shutdown at power loss, pc will reboot when power comes back on. Newer PC's now have motherboard power control which goes to the power off position on losing line power. Some of these pc's have bios setting to deactivate this function so after line power loss the pc will reboot on power return. This is common on motherboards marketed for servers. Motherboards marketed for home desktop pcs may not have this bios option. You could open the box and cut the 2 wires leading from the power on button and connect then together so the motherboard always thinks the power on button is depressed. (do this at your own risk)
