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!

The Plus Pin from Your Socket is disconnect from the Board,You can see it very clear on the Pictures.

You have to solder it new,thats all.

looks like your battery has kaput. 
That pin is a major grounding pin, and if your battery has fried then its potentially dumped alot of power into ground.. 
Be glad your board still works

Also new battery time.

This is nothing from the Battery,he only needs to solder the 2 markered Pins new.
