Device will not power on via battery or power supply?

remove the keyboard and check the connection of the power button. had the same problem once

I have the same problem, I tried removing RAM and putting it back in. But that didn't fix it. I've taken apart the laptop, cleaned the fan, and everything, tried fixing connections with buttons, but no success. Something odd, when I plug in my charger to my laptop, the little green light just goes out and it doesnt say its charging or anything, this happened a few months ago my laptop just randomly turned off by itself and never turned back on again and I have the charger problem with the light going out. If anyone can help, I'd appreciate it.

I'm having the same problem.. there is no sign that my device is working . No light any where on the device

It happens usually when carbon creates between RAM and mother board slot. Simply open RAM and clean it properly with paper as well as slot and connect as it was before. Now turn on your computer it will start working.Thanks.

My laptop was on and I am using it but unfortunately I connected HP charger and suddenly the sparking occur and my laptop did not turn on again and smell come out of motherboard for more than 10 hour what can I do if I changed motherboard how much its cost and can my laptop work properly or not whether changing motherboard work or not
