I have a Dell Latitude 7280 which complains during boot-up that the charger wattage cannot be determined. Tested with two different chargers.
Any common faults that could be fixed?
I replaced the DC jack, the original DELL LATITUDE 7280 DC30100Z300 0DP4VC.

I have been working on this laptop mentioned in the title, it initially had a blown PQ4410 mosfet.

Where should I go next? Replace the KBC or measure something else?... -

I have a Dell Latitude 5530 with a damaged RJ45 network connector. See the attached pictures.
Have already searched on Farnell / Aliexpress / Ebay and had contact with several suppliers on Aliexpress and Ebay, but they cannot deliver this connector.
Is there someone inside the EU, who has these connector(s) or perhaps defective motherboard(s) for these laptop models I have mentioned in the topic title.
