Hello; so, i have this laptop; it came with battery charged only at 5%; when i plug in charger, led laptop is lightning white for 2 seconds, then it turn off and stay off.
In bios, health of battery is excellent; charger is unknown.
I test it with 3 dell oem chargers, all are ok.
Laptop in rest is working perfectly.
I upload schematics and picture with PS_ID flow; before PQ6 i have 3,1v, after PQ6 i have 3,6v. On pin 36 of UE1 i have also 3,6v.
Laptop came with charger socket kind of ripped off, center plastic was missing. I changed with a new one.
I suspect that UE1 gone bad on function to identification of charger, because motherboard has no protection, from factory, because PD4 is missing.
And of course, PR4 have 33ohms.
I charged the battery with power lab to aprox. 11,67v = 27% in bios, but no change, charger is seen as unknown.
What to do next, guys? Thank you.
