My laptop Acer extensa 5420 do not
Want to come on. Theres nothing wrong with the battery. Sometimes it comes on just fine. Right now when I turn it on how it usually works, the power light comes on, the farthest left light of the three next to the power button comes on, turns off, comes on again, then all the lights shut off. Nothing ever comes on the screen. It makes a slight.regular noise while it's attempting to turn on.

I suggest you to perform  a power reset.

1. Unplug the AC adapter from your notebook.
2. Turn the notebook over to remove the battery.
3. Turn the notebook back over and open it.
4. Hold down the power button for 30 seconds, then release the power button.
5. Turn the notebook back over and slide the battery back into place.
6. Slide the lock tab back into the lock position.
7. Turn over the notebook one last time and plug in your AC adapter.
8. Turn on your notebook.
