XPS 9500 Power Adapter Not Recognized
Hello,
I purchased my Dell XPS 9500 (Intel(R) Core i7-10750H CPU @ 2.60GHz, Windows 11 Home) in September 2020. Recently, it stopped recognizing my power adapter 90% of the time. I purchased a new power adapter (Dell OEM) and replaced the battery. I still have the issue. The first time I boot up, the laptop will not recognize the power adapter. If I shut down and reboot, perhaps 70% of the time it will and I have no issues. My chance of success appears to be increased if I boot up up through Bios. I have plugged into multiple wall sockets and still have the same issue. Suggestions appreciated!

If the same issue was happened with both power adapters, I suggest that you may consider to replace the DC in power jack. Although, it's a low cost component, do some research for the replacement process to see if you feel comfortable for DIY prior to making the jump.

@Chino de Oro It's odd because the laptop has three USB-C ports and the issue happens regardless of which port I plug the adapter into. Or is there a single component that could be causing the problem?

When performing troubleshoot of laptop power issue, there are 3 parts with potential causes: power adapter, DC in power port/jack, and charging circuit on motherboard.
When the issue is persisted with different power adapters, acting the same on 3 different charging ports, that will narrow down to charging circuit on motherboard. Given that it's still working proper over 70% of the time, there is no need to replace motherboard yet.
There is another effort for resolution that's worth a try, test with different BIOS firmware. It's a bit risky but it can be done safely when you follow procedures properly. Here is the latest BIOS firmware for your system.
