Non charging XPS
I have an Dell XPS M1330 in. Customer wanted a socket replacement on the basis that it works fine off battery but not off DC and won't charge. They said they sometimes got it to work by wiggling the power jack.
I dismantled it and the socket test out OK in that 19.3V shows across the terminals but I changed it anyway just to be sure. This has made no difference. Still no reaction to DC power. I can't see anything wrong on the mobo. Anyone seen this before? I did have an M1330 a while ago on which the IC near the jack socket was burned out but that didn't start at all.

Does the light ever go out on the charger when you plug it into the laptop or when you press the power button?

If the jack is fine, and the power supply tests fine, and your not charging, I say motherboard. Def if you are not getting any power at all from the power supply.

Seeing as this is a Dell..................is it whining about the Adapter not being Dell?
Reason asking is I have had Dell's in where I use my Universal PSU and whilst they will power up they don't charge unless Dell PSU. I'm leaning towards the sensing circuit. Whilst it might detect PSU as Dell, if circuitry foofed, it might not let any charge through. How you check this theory however is another matter!
