Hello, this dell does not recharge the battery, the recharge percentage remains steady at 62%. If I unplug the charger, the percentage goes down (rightly) but if I connect the charging symbol appears but the percentage does not go up. By checking the ADP100 connector on the central pin (PSID) I find 3.3V. On pins 1,2,3 I find 19,80V. The message Unknow AC Adapter appears on the bios. The power supply is original, unfortunately I can't get the correct scheme but a similar one. I wanted to understand how the PSID signal works. I also tried to update the latest version of the bios but no changes. MAin is EDP51/EDB51 LA-H331P Rev:1.0 (A00)
