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.

Please make sure all devices are connected to your computer properly. Access it in safe mode and I am sure it would run, in in the safe mode just clean Windows registry database using some reliable software such as Reginout Cleaner. After cleanup process, start your computer normally.
