Auto Powerup after power failure

Problem : Have a remote site that has crappy power hence each system has a UPS installed that shuts down the pc when the power goes out, my problem is the site is unattended for 2 months of the year so what I need is a utiltiy that will power up the pc's (winxp) when the mains power is restored. At present someone has to drive 300KM to turn on the pcs after a power out. I found a bios option but this is for and unclean shutdown not a clean shutdown which is what would happen if the UPS shuts down the pc. And for me to do WOL I would have to know when the sites power had failed. This would be fairly hard as there is no one there for 2 months December / January to inform me. Any ideas would be appreciated.
Sorry if it is in the wrong forum but I didnt know if it is hardware or software.

If you you have APC UPSes:
I think Powerchute Plus Business Edition should do the trick. I use it for all my servers and it works like a charm! Nice orderly shutdown and when utility power is restored, they boot right back up.

Because of the distance, you should also look into the environmental sensors made by APC. If something happens and you loose the proper cooling-- air conditioner goes out in server room-- your servers could fry before they shutdown. With the environmental sensors and Powerchute, you are able to set temperature and humidity thresholds for orderly shutdown. But this may not be too big of an issue during Dec/Jan, huh?

The business edition is fairly expensive as the site only has 5 pcs total so not really  cost effective.   I will give you half the points for your answer. How do I award you the points?

You can also use the scheduler to start notepad for example each hour.

You need to check the 'Wake up computer to run this task'.

redrum06, I think you just "accept" my answer and assign the points. If I can think of something else, I will repost here later! Good luck and thanks.

You can also check to bios under Power Management. It may have an option to restart on power loss.

My suggestion is to enable on BIOS the RTC Power up. You should then state, for instance, that all PC's have to wake-up at 6:30. If the PC is on, you do not get affected by this. If the PC is off and the power is ok, this should startup servers.

Of course, you have to think which is the best time for waking up them, since motherboards only permit 1 RTC program...

This should not be a problem...the whole point of a real UPS is to provide
power when the main power goes off. your ups just does a clean shutdown.
Why not get rid of the UPS and accept a dirty shutdown and use the bios\fix you said you have. Or better if you have long life battery or a generator that kicks
in then set it so the UPS system does not shut down the computer.

UPS systems are notorious for bad behaviour. When I was working in Jeddah
Saudia Arabia (1980-1984) it was a common joke about once per week to go
to work and someone would say " The UPS is down !"

Most PCs will support power-up on external modem ring, if yours does then it should not be too much of an hardship to design a small electronic circuit to simulate the modem ring to the RS232 port, thus waking the PC.

If of interest let me know and I should be able to provide a design for you.

Further to my previous post, with my PC (Asus motherboard) and a Phonic external modem. I set my PC to wake on external modem, all that is required is to cycle modem power and PC boots, so in its simplest form you would need the modem plugged into a non UPS backed mains socket, when power comes back up the modem powers up, in turn powering up the PC.
