AC Adapter Diagnostic Is Always Cancelled

[aegi_kwon]

Hello, I have just bought the Omen Laptop 16. I bought it online which I expected there would be problems. But the problem that occurred was not expected at all. The laptop works fine without the charger plugged in but once I have it plugged the performance dropped hard. I had conversations with the seller and found was told to run diagnostics over the hardware. Every time I run the diagnostic for the AC Adapter, it always cancels and so other methods didn't work. 

Does this mean there is problem with the adapter? I tried looking for answers online and found nothing. The seller asked me to go to a service center which I would go a little later today. Am wondering if I can get answers here too. Or has anyone had same issues? If yes I wonder if you can share how you solved it. Thank you!
