Hi legendmms,

I’d suggest that you follow the steps mentioned below and check for issue resolution.

1. Switch off the computer.
2. Disconnect the AC adapter from the system.
3. Remove the battery from the computer.
4. Press and hold down the power button for 15 seconds.
5. Then connect back all the peripherals and check if you are able to switch ON the system.

If the light indicator on the AC adapter goes OFF when connected to the system then there seems to be short on the motherboard. You would need to replace the system board on the laptop.

My Laptop Dell Inspiron 15 7000 Series wont show anything on screen after switched on.

AC adapter is ok, power light is on and front light indicator show is charging.

And I can hear fan working.

Computer SSD was an error. It does not turn on at all. I did all of the instructions. But the computer does not turn on. AC adapter plugged in the power light is on, but turns off after 1-2 seconds. Help please. If computers could have taken to protect itself?

My computer is dead, bought new charger charging light was on when I left for work for a couple hours. Now it's not charged, won't torn on, no light except for when I plug it in then turns off. I removed the RAM and put back in, I think I removed the battery but I didn't hold the power button for 15 seconds when removed. Do I have options?

Which LED turns off?  The one one the AC adapter, when you plug in the notebook end?
