Dell Inspiron N5110 Starting Issues

by Mwagusi / August 29, 2013 9:40 AM PDT

I have an issue starting my DELL laptop. I was using it perfectly 24 hours ago in the US, but just flew home to Ireland with it in my hand luggage and removed it this evening to find that it wouldn't start up properly.

When I press the start button it sounds as though it is starting up but it doesn't boot properly and it goes quiet after a few seconds. The screen stays completely black. The three lights on the keyboard do light up in a sequence.

They light in the following sequence:
Left (Stays On)
Middle (Stays On)
Right (Stays On)
They all stay on for a second together and then all turn off completely.

The left and right lights on the front left of the laptop are also both on constantly.

Once the computer is on, when I press on switch the computer turns off instantly without any shutdown process.

Does anyone have any thoughts on what the issue might be and how to solve it? I feel there may be an issue with the motherboard but if someone could help out that would be of great help. Thanks

Many laptops have a reset feature. Some don't but as not all machines have it, here's something to try when a laptop won't start. Remember this is generic, doesn't apply to all machines but when faced with a non-starter dead laptop, why not try this?


1. Remove all connections to the laptop. (USB, power, etc.)
2. Remove the battery.
3. Press and hold the power on button for 1 full minute.
-> Explainer. Yes, many machines only require 10 or 15 seconds but this reset instruction is generic and I've found people hold the button for 9 or 14 seconds so let's write the full minute.
4. Let go of the power on button.
5. Slip in the battery pack.
6. Plug in the power to the laptop and to the wall.
7. Do not plug in any other devices.

Try the power on button!

Good luck,

This actually worked!

I've known about this fix because I tried it on a laptop years ago but I didn't think to try it again because it rarely is the problem.

Well today was the day! I had a black screen, frozen, solid white line / prompt on the screen and couldn't go to safe mode or boot from another device. Nothing was working. Couldn't even run diagnostics from the F12 screen.

Powered off the machine. Took out battery. Held the power button down for a minute for good measure and low and behold the machine started to show life! This time the prompt was blinking and the machine began to whir and spin up! It's alive! Now in Recovery Mode and hopefully smooth sailing from here.

Thank you for posting the question and thanks Bob for the advice!!

This procedure has worked so many times that it has to be in any tech or owners book of tricks.

That is, while it's not going to bring back every device, you know why I put it up for all to see.

Thanks again!
