Recently after using my laptop wouldn't power off or respond to any key presses. I removed the AC and Battery and eventually the laptop was able to power down, however since that time it does not power back on or respond to any key presses.
I've checked the AC Brick and the power output appears to be correct.
I checked the service guides provided by HP, but there is a discrepancy there. HP publishes two guides, one for models w001-w099 / w201-w299 and one for the w200. The odd thing is that the guide for my model does match the layout of the actual device, while the other manual does match.
That aside, I have also checked the DC In and it also appears to be transmitting the correct power.
From what I can tell, no power is getting past that point, let alone to the power button, which is connected via ribbon cable on the USB model and not directly on the motherboard.
At this point I am at a loss as to how to troubleshoot further.
Any suggestions or help would be appreciated.
Thanks
