I have a Dell Optiplex 360 PC what was working fine. It sat in storage for a while and now it will not boot, but the issue isn't a strait forward power supply problem like I had hoped.
When I plug in the PC I get an amber/orange LED on the motherboard, which is good since it means the motherboard is getting power. However the computer doesn't do the standard Dell "rev-up" that they normally do when you plug it in and when I press the power button nothing happens. The power button does not light up at all, not amber, not green, and not blinking. When I press the small black button on the back of the power supply (that I assume is some sort of test button) the computer comes to life, the hard drive powers up and the fans kick on but I don't get anything on the screen and it doesn't beep like it would if it had gone though the bios. As soon as I let go of the little black power supply button the PC shuts off again.
I installed another power supply just make sure and I had the same thing happen again, amber/orange light on the motherboard but the power button does absolutely nothing. I tried removing the small microchip/board that holds the USB, headphone, and power button and replaced it with another one from a different (working) Optiplex 360 and that did not work either.
I have tried removing the cmos battery and letting the PC sit without power. I have checked for bulging or leaking capacitors. I have checked all power connections to the motherboard. And I have tried changing the memory.
Has anyone seen this issue before? I hate to toss the thing since it could still be used if it would just boot up.
