Greetings,
I am working on a Bolt-L UMA MB 17938-1 board for a Dell Latitude 3500 and it is not charging. Plugging in the barrel jack and USB-C both results in about a .1a draw at 20v. I probed around and checked every capacitor I could find, as well as the inductors, and I got no shorts, so I checked to see if anything was happening under the thermal camera when plugged in and I see a slight bit of heat being generated by the Intersil 9538H IC, which appears to connect the battery to the charging line, but I may be wrong about that, I am not very strong on reading schematics, I mostly...10-25-2024, 10:01 AM -
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.

This Dell Latitude 5530 will not charge when turned off. when turned on and in bios it will charge properly and the adapter wattage is shown.
I noticed that when in bios if the charger is unplugged the bios still reports the laptop as charging and the charging light in front of the laptop stays on
When charging, PL4401 has a stable voltage of 12.8V however when plugged in but not charging the voltage alternates between 4v and 12v on PL4401
Please help -
