Dell XPS 14.1 Laptop (unk model number)



Unit arrived with dead battery.
Would not power on
No lights.

Not much information provided other than DC Jack issue.

This was not the case, the DC Jack was fine, the unit was simply not getting any power.

Disassembling and starting to trace the DC in section, the burnt section was immediately noticed. This coil (bad solder/blown pad) was a common problem on the E1505, E17xx series. So checking the coil power shows no voltage reaching the source side (pins 1-3) of the MOSFET.

The Coils bottom surface that contacts the pad was blown off so it was an incomplete circuit > Replace
Check Mosfet (out of circuit) - DEAD Short. >Replace

I cannot repair laptops for you via the internet, I can only answer questions related to posts. This is because I have not had experience on every motherboard that is out there. Bear with me.

If you do need it repaired. Contact me for quote (US/CDN Only)
