According to Dell specifications, your laptop requires a 130-watt power adapter. It might run with a 90-watt adapter, but it would run more slowly and while running would charge more slowly if at all. My old XPS laptop does the same with those two sizes of power adapter.
Hello, I have a Dell XPS 15 9570 laptop and the original charger failed. The Type C socket does not make a good contact, and the cable in it is apparently broken. My question is, would this laptop model work fully with a 90W charger or will there be a loss of power during operation?
XPS 15 9570, 130W or 90W?
