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?
