Hello,
My dell XPS 9350 keeps on having issues with the chargers, "Charger Not Recognized" issue is very common for dell machines, due to "intended" design flaw.
Dell uses 1-wire eeprom chip, which causes the most of the problems.
Last dell clone charger worked for a couple of weeks and the same problem again.
After spending some time on google, found a solution, for precisely my charger, which is 45W.
Sadly, the guy published the code for the ATTINY85, which I sadly don't have on hands, but have a pile of Arduino nanos and minis.
The big post in Russian: Заряжаем ноутбук Dell XPS от любого адаптера питания / Хабр
His code on github: GitHub - KivApple/dell-charger-emulator: Emulator of original Dell charger using ATTINY85
Also, found the code, intended for the use with arduinos, on github. Uses pin 10, for the communication. Seems like it's not matching my charger, so doesn't work

Thanks a bunch!
