How to troubleshoot your laptop at start
When you plug in the power adapter and press on the power button,
there is no signs of life at all. The laptop will not make usual noises,
LEDs will not light up, the fan will not spin, the screen is blank and
black, etc… In short, the laptop is dead.
What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is
getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is
correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct
voltage. In this case unplug the power adapter from the laptop, remove
the battery, wait for 1-2 minutes, plug in the adapter and try turning
on the laptop again.
OK, you tested the adapter and it’s bad. If you decide to replace the
original DC adapter with a generic one, you’ll have to follow this
The voltage output on your new adapter has to be exactly the
same as on the original adapter. The amperage on the new adapter could
be the same or higher.
If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with
the DC power jack. It’s possible the DC power jack is broken and the
motherboard is not getting any power from the adapter. In this case
you’ll have to disassemble the laptop and replace the power jack.
