MS-1761 laptop (GT780DX) - not charging, producing smoke and smell when power supply is plugged in

[sbi85]

Hey guys,

This issue just came up with my laptop yesterday. After unplugging and replugging a minute later I noticed that the laptop battery is not charging anymore. I have to say though the battery is really worn out, it only hold charge for like 15mins.
I can still power up the machine (it has some batter power left) but plugging it in is just producing some smell.

I took the laptop apart to see where the problem is. Here are some pictures of the power socket:

Everything looks ok to me to be honest (although I am no expert). But I can definitely feel a stronger smell around this bit.

So what do you think the problem is here? The power socket? or could it be the power supply (btw that is a adp-180hb b if it matters)?
I guess we can rule out the battery?
Anyone had similar experiences?

Since this is my work computer I’d appreciate any help you can give me.
Thank you so much in advance!

shows "black burned thing around. Your power port have soldering problem, probably replacement and new soldering. If that thing did not fry anything else (I think so, after you said it stills "booting something") I think battery saved your components.

I think you might be right. I tried to do a better picture but I don't have a proper camera here atm: https/image.prntscr.com/image/uqJeKNPOQ-uJ90g63KMVKw.png

But yeah. Good guy battery then .
I think that socket need replacement. There are vids like these that help: https/www.youtube.com/watch?v=OhryUpbTy-0

Still the question is what caused it? Should I check the power supply somehow? Maybe it did let too much power through that burned the socket?

it happens sometimes when soldering is low quality. I did same thing while stepping on my power supply (yeah it got crushed and wired shit happened). https/www.youtube.com/watch?v=OhryUpbTy-0 should be fine and I think this may help you with AC:
