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 [link|https://www.lowes.com/pd/Klein-Tools-Digital-Multimeter-TRMS-Auto-Ranging-600V-Temp/5014305581|like this|new_window=true](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:

(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.

It should be 19.5V under load, 20V unloaded. If it's showing 19.5V without a load and drops to 19V, the adapter will probably work but it’s on the way out and may not work reliably on higher end machines.
