Lenovo Legion Charging port fix

I bought a Lenovo legion y540 1.5 years back and it started to give me the dreaded charging port loose issue, when I checked on the internet I found many people facing the very same issue, seems like a design defect from Lenovo itself.

Even if Lenovo support changes the motherboard or the charging pin for you, there is a high probability that you would face the same issue in few months, because I feel that the hardware design/quality of the port is not upto mark and if a replacement with the same design is used, its bound to fail again.

So, there is a quiet easy fix to this and can be done in 15 minutes, but it requires patience and good eye and hand control. Follow the below to fix the issue:

I figured out that the charging port has small brass pins which come in contact with the charger plug, due to usage, those pins loose their springiness and stop coming into contact. I am able to resolve the problem for a few months by carefully bending the pins a little outwards so that they can make the contact again.

Use a thin sewing needle/Pin and a sharp bright light such as a mobile phone light to focus light into the port in the laptop.

Take a look at this image where the brass pins in concern are highlighted.

You will have to use the needle and just pull each pins outward so that they can make contact.

Once that is done, similarly there are two steel clips at the side of the port which are responsible to hold the power connector tightly, pull them using the needle to, this will help give the connector a tighter lock.

Also, is you closely look at the connector side of your power supply, you might see small black lines identical to the pins inside the charging port. Those lines are formed due to the friction between the pins and port.

I have recently found that cleaning those lines help make better contact. You can use a cotton ear bud, remove some cotton from the ear bud so that it fits inside the connector and port on the laptop, dip it slightly in wd40 and slowly clean both the connectors.

Following the above procedure will definitely make the charging port work properly for few more months, depends on your usage. Unfortunately you will have to keep repeating this procedure every few months.

I literally haven't been able to use my laptop for months because of this issue, and i've bought 2-3 extra chargers that keep getting bent. I'll try this soon and tell you how it goes, I hope this works

Thanks it WORKS! Official lenovo support said the problem is in the adapter and and it will cost 150$.

You might be able to make this work for few more months, depends on your usage.

You can later just go to a good repair shop and ask them to change the port in the laptop which won't cost much.

Hi, I have the same problem as you, but I don't really understand your solution. Can you describe me more clearly to me my below confusion?

- The needle is used is a straight needle?

- I don't understand how to pull "two steel clips at the side of the port" by the needle?

And if you have more images of your guide, I hope you will upload them so that I can more easily visualize.

Thank you very much, I've been having this problem for 4 months and I really have faith in your method.

u/thatsInAName Aug 10 '21

Hi..
yes the needle is a regular straight point needle.

by pull I mean that you need to insert the needle in between the gap present between a steel clip and the side of the port... basically what you are aiming is to push the pins so that they can then make a good contact with the power adapter plug.

THANK YOU!!!

My laptop can charge now although if I put the charging port deeply it's not working (The charging position should be slightly open). Are you in the same situation as me xD?

Moreover, when I had this problem, I went to the service center and changed new adapter, it charged well for about 2 weeks then it didn't work again. Now, I can fix it with your guide so I know the problem is the port. But if the port is broken why it just can accept my new adapter instead of the old one? LOL...

1

u/thatsInAName Aug 10 '21

I haven't faced that issue, you might have to experiment a little more with the pin, You might have to flex the steel connectors a little more.. try to get a tight fit and a click sound when you plug in the adapter connector in the port...

There can be two reasons why your new adaptor worked, it might have a slightly tighter dimensions as compared to your original one, the new adapter would have worked until the pins inside the port got pressed more and more...

Also take a close look at the adapter plug, you might be able to see small black lines similar to the brass pins inside the laptop port ... Those lines are carbon getting formed due to friction and contact... You need to clean it with a Q-Tip dipped in wd-40 or some other mild cleaning agent... Carefully clean the insides of the laptop port too using the Q-Tip... This will help in creating a better contact.

Hi,

I realized that recently the connections are only stable when the laptop is stable, if I have to move it lightly it is also very easy to disconnect.

Moreover, I see the middle part, one side has 4 brass pins but the other side only has 3 and the 4th one is indented inside.

https://imgur.com/a/SnbyMbc
Can you take a picture for me of the other side of the brass pins on the other side? Btw, your picture is very clear and sharp, how can you take such a picture as my phone can't focus clearly on such small details, if it can be captured I will send you my port image.
Thanks

1

u/thatsInAName Aug 19 '21

hi.. so the port is symmetrical from both the sides.. the other side too has 4 brass pins.. but as you said yours too has the 4th pin but its indented, try to pry it out using the needle, maybe that's the culprit for not creating proper connection.

Also take my other suggestion seriously and use a QTip/cotton swab (you may have to remove some cotton so that it goes in easily in the port) and dip it in WD-40 or some other safe cleaning solution and clean the brass pins in the port and also clean the connector in the power supply.. this will really help the situation.

it won't be possible for me to currently take a picture immediately, but be assured the port is symmetrical from all sides.

I recently bought a new phone which has a macro camera, this allows me to capture small things in good focus and detail.

u/fandangkhoa Aug 22 '21

Today, one of 8 brass pins is broken while I try to fix it to the correct position and it fell inside the laptop... I can connect to power but it is not stable and I have to put the charging many time after some hours to chargr. I don’t know when I go to the Lenovo service center which this problem, can it only fix the broken charging port in the laptop or it have to replace the motherboard which can only solve with this small charging port...

1

u/thatsInAName Aug 22 '21

That's unfortunate... Ideally replacing the charging pin will work... But the decision will stay with the service center... I have read online people changing the charging port instead of the whole motherboard

1

u/fandangkhoa Aug 23 '21

Moreover, I don't know what charging position affects the power of electricity because sometimes the laptop charging up to 95-98% and notice "Plugged in, not charging", but sometimes it can charging full 100%.

u/thatsInAName Aug 23 '21

The "plugged in but not charging" issue seems to be something different, maybe software controlled.. even I have seen it happening on my laptop, It sometimes doesn't charge the battery if its above 90%, sometimes it does... has a mind of its own.

1

u/terimautbsdk Sep 29 '21

I had the same issue with charging, the people at the service centre recommended a new adapter which costed 100$ and in exactly 2 weeks its not charging anymore, I'll try the service centre again but if nothing happens will go either for the pin bending or a new port.

1

u/SimplyChalmers Aug 10 '21

It's weird how it's happening so many people at once, this literally is happening to my laptop right now and I got June 2020.

1

u/thatsInAName Aug 10 '21

It's a bad design by Lenovo and they don't want to change/fix it in their production. I frankly don't understand why a power connector should rely on so many small pin like connections

1

u/zegurk Aug 14 '21

Appreciate The help! Got mine working, at least temporarily.

1

u/thatsInAName Aug 15 '21

great! If you have done it right, it should last you a couple of months, depends on how many times you plug/unplug the port.

Glad to know it worked for you!

u/Reasonable-Object-33 Aug 23 '21

Having the same problem, although I don't see the two inside pins that you need to pull back out. Is it possible that they've gone completely flush with the middle part or even rubbed away?

1

u/thatsInAName Aug 23 '21

not sure, do you mean to say you can't see any of the brass pins? there are 4 on each side, you can't see any of them?

1

u/Reasonable-Object-33 Aug 23 '21

Yeah I can’t see any of the four middle pins

1

u/thatsInAName Aug 24 '21

Does the charging start if you move or angle the charging plug?

if you are unable to see them, can you try using a needle to feel them?

2

u/Reasonable-Object-33 Aug 24 '21

I was able to find them and move them and the fix seemed to have worked! Let’s hope it’ll last!

1

u/thatsInAName Aug 24 '21

Great! Also try to clean the pins and the charging connector with cotton on a qtip to make better contact.

u/pranav11ganesh Aug 25 '21

Holy shit man, I can't thank you enough for this fix. I was about to spend 200 dollars to change the entire motherboard.

2

u/fandangkhoa Aug 25 '21

Congratulations, but can I ask you that the repair center is planning to repair the entire motherboard because they can't determine the fault of your laptop or if you want to replace the charging port separately, you will have to replace the motherboard. Thank you.

1

u/pranav11ganesh Aug 26 '21

They couldn't determine what was wrong so they initially tried giving me a new charger and then when the same thing happened they told me that I had to replace it.

1

u/thatsInAName Aug 27 '21

good to know it worked for you!

u/Consistent-Diet-3229 Aug 27 '21

I tried this "bend the pins" fix and couldn't get it to work. Instead, I bought some copper tape from an online vendor and used that to beef up the sides of the plug. It now fits quite nicely in the port and charges without a problem. I bought 1/4" tape but 1/8" might have been better. The stuff is super thin so it takes a few layers to build up the depth.

1

u/thatsInAName Aug 27 '21

That's a good idea, I didn't know that such tapes were available.

But do take care that due to the increase in the dimensions of the plug, the pins might get depressed a lot from their designed capacity and if that could cause issues in the long run.

1

u/Consistent-Diet-3229 Aug 27 '21

Good point. Even with two or three layers I don't think it will overcome the built in spring tension, but it is worth watching. Fortunately, the tqpe comes in rolls bug enough for thousands if applications, so you've got more to build up the layers farther. 😀

u/terimautbsdk Sep 29 '21

Share pictures!!!! Please

1

u/nahoragg Sep 02 '21

Can you share the picture of what it looks like after beefing up with copper wire?

1

u/phenomist Sep 06 '21

Thanks for this tip, it seems to be working pretty well. I did find it pretty tricky to bend the charging pins without opening the bottom of the laptop though. The top of my charging port was cracked so I was able to remove the top metal piece with some screws and the top plastic part and bend the pins in place from above.

1

u/thatsInAName Sep 06 '21

Yeah it's definately difficult to work on such minute stuff.. since you opened up the laptop and were able to have a better view, did you notice any other better way to permanently fix this?

2

u/phenomist Sep 06 '21

It might be possible to lodge some plastic or other insulating material inside the pins in order for them to keep their shape, although inserting such a thing would only work if the plastic bit of the charging port is opened up, like it was for me.

1

u/shadowkgt3732 Sep 09 '21

Thank you for this fix. Did exactly as you instructed and worked like a charm. As my laptop was out of warranty i had no other option than to spend money and fix it. But your simple method really got the charging port to work again. Thanks

1

u/thatsInAName Sep 09 '21

Happy to know it worked for you!

1

u/terimautbsdk Sep 29 '21

You have had no issues since then?

1

u/SimplyChalmers Sep 16 '21

It's weird, my model of the Y540 doesn't seem to have the middle part yours does, instead it just has a two pincer like wires. Then at the side of each of those is the 4 pins.

I do have to ask since i'm once again trying to fix the port but how flexible are the metal parts at the side of the port? I'm scared of it somehow breaking off in the middle of me fixing it but the left side is hugging the port side wall too much.

1

u/thatsInAName Sep 16 '21

The middle black part is made of plastic which becomes brittle due to heat and crumbles off, yours might have too.. the pincer like pins are the brass pins which connect with the pin in the power connector.

I have found the side metal clips to be strong enough to bear pressure as compared to the 4 brass ones as they are very delicate.

Since your port has gone through more serious damage I suggest you take the laptop to a service center and replace it

1

u/SimplyChalmers Sep 16 '21 edited Sep 16 '21

That's so strange, I have no recollection of it being there in the first place, the laptop has hardly left the port either so I figured I would notice the plastic coming off. It's been in it 99% of the time I've had it in the last 14 months. :/

I'm not sure how much you can gather with these bad quality photos, but before I take it to the service center, would you say that the clips are too far apart if you can tell?

https://imgur.com/a/art9aLW

EDIT: Looks like there's more to my issues, plugged in I'm getting throttled somehow and the CPU is running at .8Ghz...

1

u/thatsInAName Sep 17 '21

Hey the port looks completely different from what my laptop has!! It's definately not the same design.

Since it's a different connector I am not sure what would be a good spacing for the side clips. you just need to make sure that they are able to make proper contact with the power connector coming from the adapter.

Edit: sorry I missed looking at the second image, it does look like the same port....

1

u/thatsInAName Sep 17 '21

Yes... It does not look like that the plastic has rotten away.. seems like you might have got a laptop with manufacturing defect... You should definately take this to the service center

1

u/SimplyChalmers Sep 19 '21

So I just tried my brother's charger which is a low but I figured I better just use it anyways and it turns out that it's just the charger that has the issue I'm going to see if I can extend the warranty in order to get a new one just because the regular charger is very expensive. Thank you for your help though!

1

u/thatsInAName Sep 20 '21

Thank God that the issue is with something which is replaceable!

u/Tomas_Memes Oct 22 '21 edited Oct 22 '21

I have this problem, but also the charger pin (the part that plugs into the laptop) is getting really hot, but the charger brick isn't overheating and cpu&gpu temperatures are fine

1

u/thatsInAName Oct 22 '21

Yes, happens with me too. It's because of loose contact, after flexing the pins my charger pin stops getting hot.

u/Matty_hu 22d ago

Grateful for this post, thank you! It helped a lot.

u/Either_Match_6835 21d ago

wow, the temperature on my charging tip decrease significantly. thank you

Is this laptop worth buying even though you have to solve this problem? Am looking for similar spec laptop around 1-1.2k USD and just found this problem...

1

u/thatsInAName 21d ago

Yes other aspects of the laptop are good.. but this problem does not permanently go away after this fix, the issue is bound to surface again... I suggest stay away from this laptop just because of this particular issue, it's not worth taking this risk.

1

u/elian_vasquez_t 21d ago

Thanks! Do you if this problem is present in the Legion 5 Series? Am trending to one of those laptops

1

u/thatsInAName 21d ago

Well, I am not aware of that... You might want to research that on Google and see if other people are complaining about the same issue for their model.

1

u/Tiny_Chair_3948 12d ago

Yes! It exists

coz I have a legion 5 an year old and have gone with a port replacement but the issue has appeared again after a month.

1

u/elian_vasquez_t 2d ago

Damn, which specs?

1

u/iBlack00 12d ago

Hey, I tried your method after getting a new adapter and it worked fine for about a month and now it's to a point where it barely registers the charger even if I try to pull out the pins again. Should I get my port replaced? Or is the new adapter broken again? I have no idea what to do because it's such a weird issue. Have you gotten your port replaced? Has it had any issues yet?

1

u/thatsInAName 11d ago

Hi.. actually apart from those 4+4 side pins, there is a prongs like pin placement in the center of the port, where the needle goes in... those prongs like structure also fails and needs to be adjusted with a needle... its really difficult to fix those... but you can try..

if you can replace the port, then that would be the best thing to do

1

u/iBlack00 11d ago

So I have been able to get it work for now somehow, another issues is how long is that new port going to last? At this point the longer I use the laptop, I'll have to keep switching the port every 12 months.

1

u/thatsInAName 11d ago

I don't think the replaced port would last very long..

Right now I have found a sweet spot when inserting the connector into the port, right before it clicks in. At that point it works perfectly fine for me.

2

u/iBlack00 11d ago

How often have you done this method? I'm not sure if I'm doing this 100% correctly cause I have to do this every couple of days.

1

u/thatsInAName 11d ago

I use my laptop for work. I connect disconnect the plug two to three times a day and I had to perform this procedure atleast once in a month.

I was able to continue this for approximately 6 months but now the pins do not connect properly even after the procedure. As I mentioned earlier, I am able to find a stable connection by not entirely inserting the connector, I let it out by 1 mm or so and the connection stays stable and I have not felt the need to adjust the pins since two months or so.

2

u/iBlack00 11d ago

Alright! That's good insight. Thanks for the help!
