Question Lenovo Legion Y720 SSD SATA slot short circuit?

[retry915]

Hello everyone i'm posting for the first time here ive been content in a passive role before I had this frankly scary (possibly idiotic) catastrophe with my second-hand (week old for me) Lenovo Legion Y720-15IKB (link down below).

I was installing (not for first time the same sata ssd drive in the same setup)
a 480gt sata-ssd hard drive, with power turned off (I was assuming that the laptop battery just wasn't supposed to be removed since it was fastened to the chassis and motherboard with so many layers of screws and whatnot. I waited for (this is my own theory, though it had worked several times with the same setup and parts a couple of times already) residual electricity to dissipate and connected the ssd to the sata port (in this instance a little socket with a couple golden connectors and a thin cable in between) and was met this time with a brilliant white flame the size of a match igniting and lasting 1.5-2.5 seconds.

The visible damage was some blackened plastic and soot over the gold pins, confined inside the sata connector in the motherboard. I let the thing cool and started disconnecting the laptop battery and the bios battery. I know now that I was careless in an unbelievably unexcusable manner (i welcome advice dont take me wrong) but my obvious question is that is there anything worth trying to salvage?

I tried (furious to myself and not too careful about possible more consequences) to start the laptop again next day but it gave practically no signs of life. I will add some photos in the hour once I get home. Thanks in advance. ~retry915

Welcome to the forums, newcomer!

but my obvious question is that is there anything worth trying to salvage?
You could practically salvage the SSD's(NMVe+2.5") and ram(if the laptop doesn't have any soldered onto the motherboard but it's likely that they might fall off the grid over time if they are recognized on another platform/laptop.

It's likely the motherboard is gone kaput. You could try using a multi meter to find your short in the circuit or voltage injection but I'm assuming you're not knowledgeable in those departments.

Thumb rule with replacing, adding or removing hardware, always remove all power sources external and internal before doing the former.
