Hi All,

I have an older PC PII with a ATX power supply / connection .... ie: I need to press and release the power button to turn it on (like all the new PCs)

Since this PC is used as a server and I have power outages now and again , I was wandering if there is any way of switching the PC on after the power has come back on, without me having to push the button...

ie: when there is power the PC just switches itself back on ...

There should be a setting in the bios, look under power management, settings :

wake on lan
wake up by PCI card
power on by ring

ok but neither of those options would apply .. there will be no lan activity (Wan only) and not sure which PCI card would wake it up ... and what s 'power on by ring' ?

Modem ring up, but do not take the ones i gave, you have to look in your bios, as they are all different.

Ok but none of them will work if simply the power comes back on .. to simplify things .. I unplug power cable .. computer dies .. I plug in power cabel .. the PC must turn itself on without me pressing the button ...

if you do not have such an option in the bios, then you will need an UPS (uninterruptable power supply), to prevent it from switching off; in fact, the bios settings do work only IF THE POWER is not COMPLETELY shut off, the motherboard must stay under power.
Sorry, i misunderstood your question.
Regarding the ups : best models are those running off the battery (not switching to the battery if the power drops); they are being charged continuesly

There does not exist such a thing as i said above ! The only thing that powers up the computer is the  power switch.

That was the case in AT power supplies ... ATX can be powered up by LAN as you said above ... I'm going to see if I can get my router to do some sort of wake up signal ...

That is only if the motherboard stays under power ! if you take your power cable out, nothing will restart

Hi

Not sure whether you such an option in the bios, but I have seen in some of the machine an option called "AC Power Recovery", which brings the machine back to the state it was before the power went off.

Agree with Sajen_Jose.... It is a setting specific to the BIOS on the motherboard, but some will have a setting to the affect "power on after power failure" or "reboot after power loss"  This will accomplish what you want (as long as your bios version has it)

there should be a bios setting for AC power recovery....if its turned on, the machine should power on as soon as power hits the power supply.
