I'm looking for the schematic diagram and boardview file for a Dell Latitude 3390 laptop (motherboard 17810-1).

Specific details:
Model: Dell Latitude 3390
Motherboard: 17810-1 / 16888-1
OEM: Wistron SL KBL-R (Starlord)
Any help would be much appreciated. Thank you in advance!...
I have 3 dell precision 5560 la-k411p boards with problems. In each case the batery doesn't charge and I don't get video. I changed the charger ic but it's the same. Could somebody help me with the boardview?
3V, 5V and 1.8V are present. RUN_ON_EC = 0V. It could be the EC but i can't confirm.
