YesI don't know anything further to tell you,......but Yes.Hmmm, how about this?You press the Power On Button.This plastic assembly then presses against the Power On switch, located inside it.The Power On switch is a Momentary Contact Switch.It only closes for about 1 second.Closing the Power On switch activates a Soft Power On circuit.The Soft Power On circuit uses the 5 Volt Standby power.[The Power Supply always has 5 Volts present, when it is plugged into power. This is the 5 Volt Standby Power ]Activating the Soft Power On circuit, 'excites' the Power Supply, and turns it on. (Sounds like a steamy novel)The first chipset to receive power is the BIOS chipset.The Basic Input/Output System program (BIOS) is initialized.BIOS looks to see what DEVICES are connected, does a Ram Memory count, turns the Processor on; and hands the computer over to the Operating System. (In this case a version of Windows)-> BIOS LOOKS TO SEE WHAT DEVICES ARE CONNECTEDThis means power is sent to the Keyboard to check it,then power is sent to the Mouse to check it.Also power is sent to all of the connected devices. [ BIOS:"Okay, what we got here?.........Hmmm, the Keyboard.Yep, sent power to it, and it works.......Okay, go on........What's this? Oh, yeah. A Mouse. Power to it reveals it works.Time to go onto to any other devices, that might be connected.I gotta' get this wrapped up. Supposed to pick up eggs, and bread before I get home; or the Ol' lady's gonna' be mad." ]For additional questions please post in a Comment.Regards,joecoolvette[Chip and Chipset are slang terms for I.C.Integrated Circuit,
