Lenovo Y50-70 negative (i think) wires keeps burning up...

2019-08-13, 15:01 PM

As the title says and this is my second cable already, the original completely burned the socket so I had to break it to get the new cable to fit the socket. The weird thing about it (to me at least) is that, unless you open the laptop cover, you can't even tell that anything is wrong because everything works fine, my laptop isn't overheating when gaming or anything. (Used to have a heating problem but managed to fix that with Intel Extreme tuning utility and some better drivers). 

Edit: The image of the socket inside the laptop is included below.

Hi AllarAaver,

 

Welcome to the Community Forums.

 

I would suggest not to use the WLAN port anymore but rather have it either with the ethernet port or external usb wlan adapter instead. There are things that must be checked internally with the board itself.

 

You can also try calling technical support and show them the image of the burned part for their recommendation. 

 

I hope this helps answer your query.

Update us how it goes for you.

 

Regards

Thank you for the welcome!

And of course, I was stupid enough to forget to mention that that is the power cable, the wire that runs from the motherboard to the charger socket. 

Edit: Though I am curious on how someone from the support team of their own product could mix the two up since they look nothing alike because the WLAN socket connects straight to the motherboard without any additional wires...

Yeah that is indeed exactly the same problem i am experiencing. If you have the same laptop than you probably need to fix your fan airflow to your radiator too. I just used regular paper and the stick paper glue to cover the places where the flow can leak. This one sorry laptop im telling u brother.

This is what my socket looks like now... After replacing the original piece for a third time i decided to order a solder iron and just replace the aluminium wires with a bit thicker copper wires and solder them right to the motherboard connections to see if that works. It should arrive in 2 weeks or so if it works ill let you know.

Hello. I've got the exact same issue. After my 3rd cable burnt I started buying them on bulk, but the last one only lasted 3 days. There is a huge and horrible flaw with this computer and that makes me mad, I really hope there is a long term solution that does not involve changing cables twice a week. Without having to solder anything, please let me know if you have any solution. Thank you

Hello, sadly i've encountered the same problem over and over again. The cable keeps burning down when i replace it. I tried to unplug the battery but that did'nt make any difference. I'm not very expirienced in these things and I hope you can help me with that problem. Sorry for my english skills, they are probably a bit rusty. I'm looking forward for a solution since obviously many people got the same problems. Kind regards Tarox

Just had the same problem in one of 2 Y50-70's. Pin 6 (red) is also somewhat darkened. So can someone from Lenovo support answer the real question: What is the root cause of this after 4+ years in the field and how do we fix it, other than buying a new computer from someone else?
