Dell XPS L702X won't turn on
I was using my lappy as usual and suddenly i hear a single tick like sound.... Sounded like a tiny spark, after that my laptop just went dead, ive tried powering it up but nothing happened and when i reconnect the adapter to the laptop the green light on the adapter goes off ! I've tried removing the battery but no luck so far !

From what you've described, the power circuit was fried by a shock. It's entirely possible something else may also have been damaged (the memory, the CPU, etc.) -- but you won't know until you replace the mainboard and try to get the system running.
That unknown, plus the cost of repairing a system that's still on the order of seven years old, despite it being new to you -- may argue for buying something newer. You could wind up putting a few hundred dollars into a system that's not worth that much (or not much more than that).
As with an older car, you have to draw the line somewhere - and computers age much faster than do cars.

There is a short somewhere. If the LED on the AC adapter is ON before you plug in the notebook, it's OK. If not, replace the adapter.
If the adapter is OK, next replace the DC power jack:

And if that doesn't solve the problem, the short is on the mainboard - which will need to be replaced (or may not be worth replacing given the age of this system).

If the system won't power up with a charged battery, given the other event you mentioned, I can almost guarantee the mainboard is fried.

It can be fixed - the board will run between $150-350 depending on type of GPU -- but the question is, do you wan to sink a couple to a few hundred dollars into a system that's upward of seven years old? Only you can answer that - if you can replace the board for $150 or so yourself, it may make sense. If you have the 3D version and the board costs $350 -- or you have to pay for labor -- it tips the balance more definitively toward replacing rather than repairing the system.

Do you know what was replaced? Mine now has the same issue. Will not power up with charger or battery. When charger is plugged in light goes out on brick. I've pulled the board out and pulled all accessories along with CPU. I then plugged power into bare board and get same result, so there is a component on the board somewhere that has failed. Anyone have any idea which component would be suspect? I know this is an older computer, but I'd have to spend some $ to get a new one that matches the performance of this thing.

I disassembled mine to clean the fans and added thermal paste to the CPU and GPU and put it back together and now mine won't power on, looking for solutions also.

Same here. New thermal paste. Xps17 not powering up. No chargelight on laptop.
Is this the motherboard?
