I am working on an older HP Pavilion Model 6830. The first complaint is that it would not turn on. I pressed the on switch several times and it fired up. Now it will not shut down. Even pulling out the line cord doesn't reset it. Plug the cord back in and it is still on. The p/s is an ATX-105.
There is nothing else attached. No keyboard, no monitor. I am just going by the sound of the fan and front panel LED.
The power on switch goes to the mobo through a connector. Unplugging this connector and testing the switch it tests good for continuity. It is a momentary contact switch which tells me that there is latch someplace. Is this latch somewhere on the mobo or is it in the p/s itself?
Advice please.
