D530s will not power up, odd blinking green LED on mobo
I have been all through HP docs and no info to be found.
My D530s shut off unexpectedly when I unplugged a USB device.
It will not turn back on, when I press and hold the power button the power LED blinks green constantly at a medium-fast rate and continues to do so until I let go of the power button. No system activity or power on occurrs.
If I look at the mainboard, the green LED by the CMOS battery is blinking constantly at a medium-fast pace (no sequences, it is constant blinking at same rate).
If I unplug power it keeps blinking green until the caps drain out. When I plug in power it starts blinking again.
What do I need to replace, anyone know? HP's site has no info on this and i've been through all of the tech docs.
thanks in advance-

Ok, this is acting as if your MB is getting power but doing nothing with it. This very well could be a MB problem where something (unknown without looking at it) is fried. Just for grins, take the cmos battery out and let the pc sit for 1/2 to 1 hr before putting it back. If this does not work, I would contact HP for a replacement MB.

OK, this can be a hard thing to fix. Most of the time, the power supply is the first thing to go on a PC. However, when you stated that the motherboards LED came on after you unpluged the PS from the motherboard, it leads me to believe that the motherboard is the issue but the power supply might be outputting higher voltages and the motherboard might be shutting down. Since the power supply is cheaper then most motherboards, I would recommend getting a new one. Check ebay for a new power supply. It should be about $20 with shipping. If the same thing happens, then you need a new motherboard...
