Dell Precision 3510 completely dead

Re: Dell Precision 3510 completely dead

Yes, pin 1 and 2 as well as 3 & 4 are connected together.

From picture PU602 seems to be missing all the pins 2 to 5. Am guessing the burnt copper trace may have penetrated bottom layers, try cutting out the 'bulge' and see (if you are comfortable doing that. You'll also need to rebuild the other traces.

Maybe PU601 is on the other side of the board?

No worries about the traces, i'll pull new copper traces directly from the nearby SMD.

Yes i found it on the other side, is a large IC with 36 pins, if i have to remove this i prefer buy a used MB
Any workaround?

Re: Dell Precision 3510 completely dead

Per schematic, FCCM_VCORE goes only to these 3 IC. The only way to confirm would be to remove it. It easier than it sounds. It's your typical TQFN, preheating the board will help.

If you plan on buying a used MB, might as well use this one for practice

Re: Dell Precision 3510 completely dead

What i can't do right is to apply solder and resolder these TQFN because the solder is underneath, i'll give it a try though.

Am sure you can find guides online. Try on scrap boards if you have some.

Removed PU601 and resistance between Vswh and GND is now 3.8KΩ.
is that good?

Re: Dell Precision 3510 completely dead

Measure resistance on pin 1 - 5 of PU602/603 again and report back.

That's with the Inductors removed, correct?

Inductors??

Re: Dell Precision 3510 completely dead

Inductors = Coils (the grey square thingy).

PL603 and PL604 yes, are disconnected.

Re: Dell Precision 3510 completely dead

Meanwhile i grabbed a bargain, bought a MB with i5 and GPU for 35€ including P&P (small issue a bazzing noise but i think it will be easily fixed)
I will continue with current MB in case it can be saved, otherwise donor

Re: Dell Precision 3510 completely dead

Is there any success with the board?

Re: Dell Precision 3510 completely dead

First bought no, was completely burnt due to short.
The bargain of 35€ works great and laptop sold to a very satisfied customer : )
