m16 R1, lower wattage power adapter
When I power on or reboot my laptop I get the next message: "You have plugged in a lower-wattage power adapter, USB-C charging device, or power pass-through device. Your system will continue to work, but may not perform at its peak. " I already bought an external power supply to get the 240w my AC adapter requires, but still getting that message. Could I need to buy something specific or increase the wattage of my AC adapter? I'm still using the original one.

If you are using the original power supply that came with the machine then you definitely have a problem somewhere.
You can press F12 while booting to get into the Boot Menu and from here you should be able to select the diagnostic. This will scan your system and tell you how much power the adapter is supplying.
Make sure that your BIOS is up to date. If not, update it.
You can also try removing the adapter from the laptop and hold the power button down for 30 seconds to try and reset the power. This can work better with the battery unplugged, if you wanted to open the laptop up.
When all else fails, contact Dell Support and ask for warranty support.

@mattyb3 OK I'll try if not looks like I'll request support.
