I turn the laptop on and the WiFi light flashes along with the two lights on the right side. The fan runs for about 3 seconds and turn off. No display or hard drive sound. I connected an external Monitor, but no display on it. I removed the battery and held the power button down for 30 seconds. I plugged it back in without the battery. No difference. I put the battery back in, no difference. I reseated the RAM, and HD. Same thing. I completely took the laptop apart disconnecting everything. With just the motherboard and power button connected, I plugged in it and got the same results. I took the fan and processor off and cleaned them. Put them back with fresh thermal paste. Reconnected the power button to the motherboard and plugged the power cord back in, Same thing. Does anyone else have any other ideas before I spend money on a new motherboard?

I have gone through all the steps in each article. Most I had already done, but nothing seems to help any. I have no way to test the motherboard, since I can't get far enough to run doags on it, so I have about given up. The laptop is just over 3 years old. I would think it would still have lots of life left in it, but I guess three years is as good as it gets these days.
Appreciate all your help.
