I turned on my satellite 155t a5290 last night and the backlight lit up but there was no display. I did some research, opened it up and disconnected and reconnected a few things (which I do often) and closed it back up. When I tried to turn it on this morning it was unresponsive. Although I've checked and rechecked, is it possible that I didn't reconnect something securely that would keep the laptop from turning on? How is it that it could go from semi-working to unresponsive overnight?
I've taken the entire thing apart in no particular order, plugging it in and trying to turn it on at random intervals. Can I troubleshoot as I put it back together, or should I put it back together and have someone walk me though the best sequence for taking things out?
As of now the only things connected are the motherboard and CPU, both of which I've taken out and cleaned.
