Mame machine turning on.

[Mellor]

Hi,

I've sold my Naomi mame machine on Ebay now but it does have a very minor problem I never mentioned in auction that I could maybe sort in the timeframe before collecting. You turn the machine on at the plug which gives power to the monitor. I then put a small push to lock style button from Maplins and connected it to the Power SW of the motherboard. The machine will power up fine but it sometimes takes a random number of pushes before you hear the cpu fan come to life and the machine actually boots. If you press it to shutdown, I hold it for this. Then windows immediately starts shutting down and it works! It is often about 4-5 pushes before you get power the the mainboard! Any ideas?

PC motherboard power hasnt been "lock on, lock off" since the days of AT power connectors on motherboards. All modern (i.e. the last 8-10 years) ATX based boards use a momentary switch to turn on/off the board.

Try replacing the Maplin locking button with a momentary button (arcade pushbutton is fine) - or just ripping the wee bit of metal that provides the "locking" functionality off the maplin button with a pair of pliers to convert it

Absolutely right, swap out that button and you'll be in business.
