Solved!
Go to SolutionXPS15 9560, AC adapter not recognized
For some reason my power adapter (original dell) is not recognized by the system and the battery is not charged.
- with AC adapter plugged in I get the following error message at boot: "Charger - The AC power adapter wattage and type cannot be determined. The battery may not charge."
- in the bios under battery information it says: "AC adapter = Unknown" (bios 1.18.0)
- After running the test session I get the following message: "Testing completed. One or more errors were detected." I do not see where to access more details.
What is it wrong?
Best regards

Try another AC adapter. If the issue still persists:
If you are lucky your DC power jack ist defect, replacement is a few bucks and a few minutes work.
If this does not help your charging circuit on the motherboard is broken. This gives you three options:
1. Replace it for about 600 bucks
2. Buy a docking station for 200 bucks
2. Buy a USB-C charger > 60w and live with a crippled system. (gpu will be massively throttled because dell)
no apparent reason. At a certain point, I noticed that the battery was not getting reloaded, I restarted the computer and then I got the error message mentioning the fact that the AC adapter was not recognized.
It appears that if I drain the battery till the end, when I restart the computer after it dies the battery get charged again. The problem reappears once I close the lit.
The problem is clear in the bios and it thus do not depend on the OS.

Hi,
I got the same issue (BIOS diagnostics error message reads "Charger - The AC power adapter wattage and type cannot be determined. The battery may not charge.")
This appeared right after I upgraded my BIOS from 1.16.0 to the most recent 1.18.0.
Best regards.

Thought I'd post an update with some good news.
I spoke with Dell and did some basic diagnostics and they said I needed a new DC jack. Interestingly enough by this point I'd already tried 2 DC jacks, however, they were from eBay, not from Dell.
After agreeing to purchase the 64TM0 DC jack from Dell for £27 with postage it arrived a couple of days later. Being familiar with the DC jack replacement, I did it myself (3rd times the charm) and straight away the laptop began to charge without issue.
tldr; replaced DC jack with Dell official spare 64TM0 and it worked fine (avoid eBay spares!).
