So my Lenovo laptop will not turn on at all, like what so ever. I took out the battery and put it back in and it had no effect. I tried taking the battery out and plugging in the charger without a battery and nothing happened. I can't get anything out of it at all, the little LEG/indicators on the computer won't even turn on, only the charging indicator on the side of the computer turns on and starts blinking, other than that, there isn't any signs of energy throughout the whole thing. I wanna know what the issue is so I can fix it. I think its the motherboard because the computer would at least have the rest of the indicators on and the fans would start running if it were just the screen. Someone please help me out here. I really wanna fix this thing and I don't wanna change the motherboard for a hundred something and then it end up not working still.

Replace the power cord from the AC adapter to the wall.
Does the AC adapter have an indicator light? Does it come on when plugged in?
Use a volt meter to test and see if any power is coming down the cord from the adapter to the laptop.
Check the DC jack on the laptop - does it move at all? It is not uncommon for these jacks to come unsoldered and need replacing. If you have a steady hand and an inkling of soldering technique you could replace the jack yourself for about $3 for the part.
