@beviswulff I assume that your laptop is telling you that. Is it the original AC adapter? Have you checked the voltage on that? What have you checked?

Check the sense pin - Dell laptops are super picky about that, ESPECIALLY ONES that preclude USB-C only charging. You'll need a new AC adapter if it looks damaged or missing.

If the pin is fine, then I would get a multimeter like this(1) and check the adapter. It should be 19.5V or better without a load - sometimes 20V or more. If it shows less then this without a load the adapter may be slowly failing, or work but have issues with high spec machines. This is what one I tested showed me:

If the adapter is fine, the jack inside the laptop is damaged. PartsPeople sells it, and you can get it all in for ~$23. It's not hard to install. Dell has the SM online for this machine.

(1) - You can get away with using a cheap $20-30 meter from a big box store like Walmart, but they are unsafe to use on anything beyond low voltage DC applications. I don't recommend any of them and the least I ever recommend is a True RMS Klein (with Fluke being the best, albeit expen$ive) but it's an option. But I can't recommend any of them in good conscience.
