Why isn't my computer turning on despite the battery and power lights
Battery light shows laptop is fully charged, when I press power, power light turns on too, but the screen remains black and the laptop isn't starting, just the little light is on.

Bryan Chen remove your AC adapter, the battery and the memory modules. Hold the power button for about 15-30sec. Then reapply the AC adapter only. Try to turn it on. If it does start replace the parts one after the other, not all at once. See if there is an issue with restarting with a particular part. This behavior could be caused by a bad memory module.

Hi!
We need to determine your problem first.
Point a flashlight at the screen and see if you can just barely distinguish what was supposed to be displayed.
Connect your laptop to any sort of external display, tell us if anything is shown.
Re-seat your RAM memory.
