Dell XPS 15z does not charge

[hazardus]

Hello,

I got another Dell XPS motherboard with charging problem.
When I measure 3.3V and 5V these are not present when the charger plugged.
Anyway the laptop turns on if you press the power button. I believe this is why it's not charging. What could be the problem? Bios?

Hy , you can try a dump bios, but i`m not sure will resolve the charging problem.

I think that the C.l. charging is the problme, possibly a voltage source.

I changed the charger IC it's charging but really slowly.
PL10 shows 15.3V without charger. With charger 15.8V. It should be above 16V I believe because the battery almost fully charged but anyway after an 1 hour charge it went from 91% to 95%. I checked everything around the charger circuit but I didn't find anything suspicious. Anyone?

I checked the PL10 with scope and looks like both side is straight 15.7V. So PWM doesn't work. I replaced the chip again but I got the same result. I attached a pdf. The highlighted components are checked and those looks fine. What should I check? What could be the problem?
