I got a laptop that will not power on (Dell Inspiron 3541).
Things I did:
What if I replace the motherboard (purchased from eBay) and that does not resolve the issue?

Edit:
The motherboard is obviously shot and other components may be as well. The customer is not going to have it repaired. I charged him a diagnostic fee since I could potentially fix it. I also transferred data from his HDD to his flash drive, so I will be making some decent moolah
Things I did:
- Tried universal AC adapter
- Tested DC jack's pins - everything is good
