Shorted Power Button Board?

[Larry767]

I have a 15-g050ca laptop that was given to me. I found that whoever had tried to take it apart in the past had ripped the ribbon cable off the power button board. I was able to jump start the computer and verified that there were no other problems besides the broken button cable. I bought a new power button assembly but it did not seem to work. I plugged the power in and unplugged the ribbon cable from the mother board but in the process it triggered the machine to power on. While it was powering on I reinserted the cable and closed the clip but a few seconds later it shut down. As I pulled the cable out it started up again. I believe the system is behaving exactly as it would if I powered it on but then held the power button down until it shut down. Thinking I must have gotten a defective power button board I returned it and got another. Unfortunately, the replacement is doing exactly the same thing. Is it likely that something is shorted on the motherboard or am I simply not reassembling the cable properly?

Just to update you, I was able to confirm with a continuity meter that the button assembly I purchased on Amazon was not functioning and was behaving as the the switch was always on.  I returned the button and the replacement is exactly the same.  I know that I am measuring continuity on the correct pins because I still have the damaged original button and it is still functional on the correct pins.  Note that I cannot use the original button because the ribbon cable detached from it and pulled one of the pads completely off.  Anyway I am hoping I can find a working button assembly somewhere and get this machine back in business.
