My Dell Inspiron n5110 won't boot. I was using it fine and shut down normally to go over to a friends house, upon arrival the laptop just won't turn on. When I connect my external fan to one of the USB port closest (to the left of) to the power button it will still turn on but when I try any of the other USB ports there is no power to them. Also none of of the lights will turn on, that being the power button light, all of the indicators at the bottom, the screen, the alternate keys to turn on or off the screen/menu and so on.I have tried to unplug everything, take out the battery, and hold the button for 20-30 seconds to drain all the extra power inside, I've tried letting it charge/starving it of energy. And nothing has changed. No lights, no screen, no indicators. How can I get it working?It has really personal things on it so taking it to the geek squad is NOT an option
I then got the advice from a Dell employee on Yahoo Answers:
1. Connect the AC adapter to a known good power outlet. Check Power LED indicator on AC Adaptor without plugging into the Notebook.2. If LED on the AC adapter is not lit when unplugged from notebook, reseat brick and cable.3. If LED on the AC Adapter goes off only after connecting to notebook, may be the power connector or the motherboard is at fault.4. Also, would suggest you to take the battery out and only connect the AC adapter and check if it turns on.
to which I replied
Dell, I have tried all of those and it is still not working. The power light on the adapter stays on all the time (even when plugged in). I've taken out the battery and tried just the adapter, I've tried just the battery (it was fully charged as of the time it stopped working). Even the indicator light saying the laptop is plugged in (on the laptop) isn't turning on when it is plugged in.
Welcome to the Community.
You have done most of the troubleshooting to isolate the issue. I would suggest you to unplug customer replaceable units one by one to isolate the issue further. Customer replaceable units are:

If the issue persists, system board needs replacement.

I have carefully pulled both ram and tested the computer without each one. Meaning I kept one in and tried to turn it on, alternated then tried again. And nothing changed, still dead. Next to the optical drive
Removing the optical drive didn't change anything and I was not able to remove the keyboard at this time.
Thank you for the reply.
It seems to be an issue with the system board. If the system is under warranty, send me the Service Tag and the name listed on the account in a Private Message.
I have the exact same problem, how was this resolved.
