    Can you have power straight on PCs? Soon they receive power from the mains?

    We bought the little lovelys brand new computers at the beginning of term, but vandals have struck again - they're constantly pressing the power buttons in so much that the mechanism inside snaps. The button still works but just about.

    Is there a setting in the bios, or something we can change - so that they power on straight away as soon as they receive power from the mains?

    They have a foxconn motherboard, manufactured by Novatech.

    Usually there's a "what to do after power outage" option - with choices "on" "off" and "last state". Choose "on", and I guess you're laughing.

    I'm not sure about that - sounds iffy to me - we have RM machines and I'm aware of a "power on when keyboard pressed" which we used at our old school and worked pretty well - planning to implement it here too.

    use the wake on lan function? i am sure there are settings to shutdown and startup your machine somewhere in the BIOS - then you can glue/cover up the power on switch.

    All depends what options you have in the BIOS. They all seem different...

    Thats excellent guys thank you - changed the settings in the bios - so as soon as someone hits any key or moves the mouse, the machine powers on. genius!

    Somebody somewhere must make/know of a simple widget to place over the two power switch pins on the motherboard to switch it on when main power comes on (would a simple HDD-style jumper do it, or would that confuse the PC into thinking it needed to switch itself off again?). A quick Google search doesn't produce much, but I get the impression the solution might involve the term "flip flop".

    Edit:

    Oh yea. That too!

    The "on after power outage" thing won't do it - that only works if the PC was on at the time of the outage.

    Wake-on-LAN is your friend in this situation.

    and if your looking to disable the power button it might be easier to yoink the cables from the mobo rather than physically fix it on the front.

    That would make it impossible to turn the PC on manually though. At least with wake-on-lan, they wouldn't need to go near the power button (thus ensuring it doesn't get bust in a week) but could use it if they needed.

    I'm thinking, for example, of after-school activities; we have a couple of groups who use some of the PCs in our IT Suite after school, when all the computers have turned off. They simply turn on whichever 3 or 4 they need; it would be a shame to have to run the whole room for another 2 hours just for those handful of PCs.

    That's where the mouse and keyboard power on function comes into play Nick. You move the mouse/press any key and hey presto! That way, if WOL isn't working either you still have a backup way of turning the PC on if the button is bust.

    Assuming the BIOS supports it yes, but it is far from universal.

    Well yes it is, but it works on the OP computers - he's already said that. So wouldn't you class that as a fix to his problem? If his BIOS supports that feature?
