Troubleshooting: Laptop doesnt start
If your laptop does not start at all or it starts but will not boot properly, it’s possible that you can fix the laptop at home without taking it to a repair center. Here are some excellent troubleshooting tips for you:
Situation 1.
The laptop appears to be dead. You plug the AC adapter but the LEDs (power light, hard drive light, battery charge light, etc…) do not light up and the laptop will not react at all if you press on the power button.
First of all in this situation check the AC adapter. You can test the output voltage with a voltmeter. If you cannot do that, find a known good AC adapter and use it for testing the laptop. It is possible the laptop appears to be dead because the AC adapter is bad (and the battery is discharged). If you know that the AC adapter is working properly and it outputs correct voltage but the laptop is still dead, most likely you have a power issue on the motherboard (or power board on some laptops) and it has to be replaced.
