The internal battery when dead can stop a machine from booting. NOT ALL MACHINES DO THIS but it's just a quick measurement with a Volt meter or a few dollar battery.
i stored my emachine desktop for a year and it worked great when i stored it( dry storage, covered, and off floor). today i got it out and hooked everything up and turned it on. It turns on and starts running as fast as it can go and doesnt stop. i have no signal to the monitor and nothing to the keyboard or mouse. i tried another monitor just to be sure and nothing to that one either. i turned it on and off several times with no change.. full out as fast as it can go. im wondering if the internal battery could go dead and cause this?
