What could be wrong if the laptop doesnt power on at all. (No lights, fan doesnt turn on, nothing) I replaced power supply, checked cmos battery and it still didn't work. The laptop battery is not the issue either. Everything is plugged in and snug. What else could prevent it from powering on? Any help is appreciated
Thanks

Bad hardware

If you have gone through all of the sections above and your laptop continues to not turn on, it is likely a hardware component inside the laptop has failed. We suggest contacting the manufacturer of the laptop for recommendations on how to get it repaired. You can also take your laptop to a computer repair shop as they may be able to diagnose the issue and replace bad hardware.

With an original or one that is "supposed" to work with your laptop?

What could prevent it from turning on?
1. A bad battery. Some laptops refuse to power up if there is a problem with the battery. Remove the battery to be positive that is not the issue.
2. Dead motherboard
3. Dead cpu.
4. Port on motherboard that connects adapter to laptop.
5. A power adapter that is not the correct unit for the laptop.
6. Bad cord on power adapter.
