[QUOTE="alpina, post: 1650084, member: 347838"] Only if you remove the Cmos Battery , any other time it will only light up number 1 LED and not start, I've carried out a continuity test on the Button and I only get a reading when the button is depressed so its working normally all the way to the connector on the logic board its so frustrating that the machine works perfect when you get it to the desktop but once you shutdown the machine it will not start back up until you take the display off and remove the Battery, you can put it to sleep and it starts fine as long as you don't disconnect the power supply Thanks for your Help Nick [/QUOTE]
