- Old School soldered-on DC jack replacement today. I'm a bit jank at these because they went out of fashion around the time when I started trying to get good with soldering, so never actually got much practise on them.

You inspire the right to repair, I have never thrown anything away with a small problem, even with my children's toys, you got brought to my attention last year by RUclips algorithm and your confidence inspires me to repair my tech.
Hi, thank you very much for this video. Mine did the common problem of the plug breaking inside the DC socket. I have never attempted to do any thing like this before on a laptop. After watching your video, I purchased a new socket and went about changing it.
After putting it all back together, success fired up straight away when I turned it back on. Checked and it’s charging the battery. Brilliant thanks.
Honestly it's the STUPIDEST design to have the tip snap off into there!!
I am not an expert in Electrical Mechanics. The important thing to note here: We have to use a Plug and a Jack or Receptacle. The one with the Center Pin is the most prone to failure due to tampering. The weakness of a center pin is always to the bottom (where it makes contact with other material). It is for this reason that in an AC/DC adapter it is preferable to use a female plug and of course that the jack to be used is the one that has the central pin (male) and also that its anchor terminals are correctly soldered.
There are both on the market: DC Power Plug with Center Peg & CD Power Jack with Center Peg, to meet the needs of different consumer product applications (audio, TV, PCs, phones, etc.)
Finding a correct plug or jack to replace would take me hours; so I prefer to do my searches at night.
Thank you very much for your time and sharing this brand with us. All the best.
I have always bought pre-builts and added bits to them. Watching your vids has inspired me to do a full, from-scratch build. Just waiting for a couple of bits and it's game on!
It's more satisfying having a PC built by your own hands and not just an off-the-shelf machine.
Got to 45 then thought Na, I'll just buy it off the shelf. Less than six months and I was building a proper one. Cannibalising bits and pieces.
@@DaleDix Well, there's a bit of that going on too. No point shelling out for new things when you have the exact same parts working, tested and ready to go. RAM sticks & the 800w PSU will get ported. Everything else is new(ish).
UPDATE - All done. I'm now running an MSI X370 Gaming Pro Carbon with a Ryzen 7 2700X and RX 580, and running like a charm!
Yes! I did a lot of DC jack replacement's on the older laptops; thankfully they improved on the design virtually eliminating such repairs, "great video" and reminder of the past.
The soldered in DC jack is quickly coming back in style... in the form of USB-C.
Oh man, this is a good point. I don't know how I feel about that yet. I like Type-C charging a lot, but it's not an easy connector to replace.
Volume
And gaming laptops still use them unfortunately
I've been using Windex for cleaning for yrs with no problems then eucalyptus oil to clean & a little correction charging ports with fly leads they still do break Acer, Asus, Toshiba & many other brands I see with thick stiff wires are broken at the connector regularly, as for the desoldering gun I just use lots of flux, heat & good wick to clear holes in the PCB, low melt solder on DC jacks on PCB's UMM NO but smaller connectors always then clean, flux & lots of heat with wick n all good been doing this stuff for 40 odd yrs n love it anyway cheers Graham n good job!
Hey guys, I managed to use "Gorilla superglue, Brush and Nozzel" and a plastic drinking straw on a iPad with broken Headphone Jack still inside. checked the straw will fit over the broken jack, before putting the glue on, put a small amount glue on the inside and the flat the end of the Straw, but keeping the outside on the straw clear. Pushed onto the jack and left to dry. worked a treat. Save the user the cost sending to Apple.
I'm using Sorin's method... hot hair on tweezers... and when them become red... just insert them onnthe plastic of connector...wait a bit... and extract
Melt an end of a hot melt glue stick and push it against the connector. Leave it cool down for a bit and then slowly pull with a slight circular motion. If some hot melt glue gets in then it can be easily removed with IPA. Hot melt glue sticks are even used to pull out broken keys, dents on cars, etc.
Thanks for your time and effort.
Another excellent repair video. Well done Adam!!
"Just to please the comments we are using some kapton tape" - yes, we are pleased thank you
I've fixed the power jack on 2 laptops before, one HP had a broken pin (plastic inside chipped) and I replaced it for a few freedom bucks and there's one where the plastic holding the jack in place got bent and fell in the laptop, fixed that with some tape to bulk it up just enough to fit. If it was on the motherboard I wouldn't have been able to fix those in an afternoon on the kitchen table.
I normally use staple pins. Staple a piece of paper, take the small wire and straighten it up then make a small possible hook out of the wire and insert the hook and pull the broken charger piece out. I have pulled out many of then it works all the time
You're right about the Windex, you don't use it on screens. I have a natural, Eucalyptus oil, LCD cleaner that I use. Works great!
Is the the glass cleaner you use alcohol based? I definitely had problems with alcohol-based glass cleaners on displays that had a protective film on them.
Vinegar. Most of the glass cleaners I've seen are essentially water/vinegar mix, which might explain why I never seem to have problems with them, while others who have seen issues are using alcohol-based ones.
cleaning stubborn holes:
get yourself a floppy/ide cable, cut the ends off, separate a single wire, remove the whole insulator by pulling it off, roll it clockwise.
now clean the tip and heat the solder in the hole and let the wire through keeping the heat on both and pulling from the other side (don't burn yourself).
this will roll up the solder out of the hole onto the wire but the wire has to stay very hot.
I use inertia. If you're careful, you can use a screwdriver handle covered with padding like foam or bubble wrap and tap near the hole gently at first to get it to move enough to grab it. Not something to recommend but it worked once for me when desperate.
Lockpickers have this look tool for extracting broken key parts. It's sharp hook. That may work.
In the past I've used a GripStick from iFixit to remove headphone jacks from iPads. Might work on DC jacks?
Good Job Sir. usually the cost of and time for mainboard repairs on this cheaper model makes most owners just go for a replacement PC. hope fully nobody give you any flack about the dirty CPU fan :)
......And cue loads of comments about the CPU fan dust..... :) , However, I'm sure Graham did it off camera ! ... didn't you?
to clear holes I use a hot air station and an ordinary solder pump, works a treat
That's a neat idea, I'll have to try that one!
Take a pin, put a small L shaped bend on one end. Heat the sucker up & insert - then rotate 45 degress whilst hot - to get a 'hook' into the part to remove. Then wait for it to cool, and extract the broken tip. Or, have done with it, desolder and fit a new one, as you have done here.
With DC jacks ive heated up the end of a pajr of tweezers that i dont care about and melt into the plastic of the charger end, then pull it out. Headphone sockets on iPads I solder a wire to the top and pull it out! 👍
3:34 Your unit have the jack body secured with two screws on the plastic body so won't be any fatigue breaking.
You'd think that, but this design doesn't alleviate "up and down" stresses on the jack. So when the customer snags the cord, or wraps it around the laptop, the jack _pivots_ on those screw joints and it pulls or presses on the positive pin.
I'll admit that these newer small jacks are probably too small for that to happen, but yea, I've seen the above on older laptops. The best way is still to put the whole thing on a wire so the jack can jiggle around and have some give without breaking. And if it does break, it's a 5min job to replace.
sorry not had a chance to watch your videos but epc 108k subs and your going stronger than every!
When will the opening scene show the new shop?
Is this a new shop? I supposed to be just a vlogger recording "zone"
I would have run the air duster through that fan, looks like a failure waiting to happen.
Your added touches are worth it graham, customers will notice and remember your service :-D.
Thankfully that machine didn't have the power socket with a line directly back to the startup super io chip, 19v gets back to the chip and poof!!.
I have a ancient acer aspire 5315 from 2006, even it has the power on a fly lead.
Lenovo has no excuse, the idea has been around a loooooong time.
A line back to the super I/O chip? What are you talking about. The I/O chip is always fed power from one of the low voltage PSUs on the motherboard, 3.3v or 5v. There is never a direct 19V line to the super I/O, nor is there ever any chance that 19V can reach the I/O chip. What are you smoking?
@@johnbos4637 Im smoking nothing, it is a design fault in some lenovo laptops that talk to the power supply brick.
When the power socket is damaged, the line can get 19 volts back up to the chip, this is a real fault.
There is no protection for this communication line.
@@zx8401ztv I don't see how a 19V line can get back to a chip that runs on 3.3V because there is no direct connection. Exactly how is it getting back to the I/O chip and where is the fault documented that supports your argument?
Which Boardview do you use, please, can you include a link? I am learning a lot from you! Thanks and good day ...
A fine Fretsaw Blade is a great Tool for removing broken Key's out of a Lock, it's so small it will fit in nearly every gap.
Just push the sawblade in, turn it around that the teeth can grip the Key and pull the Blade with the Key out...
Maybe also usefull for broken things in DC-Jacks and other Stuff.
And if someone wanna try this, the sawblade grips just in one direction.
Also a good good idea to cut off the ~3cm at the end without teeth.
Nice Job Mate you wont get critisism from me i think what you do is very skilful and clever 👍👍
I cant get this thing done with my station ... I dont want to blame the tool,, but I need to keep it FOREVER to take a jack out. The only thing it can remove easily are small smds .... it is Yaxun 882 with the air pump on the handle. What I really love is the desoldering gun, I used to work with one from goot .... man, once you master it .... it is unstopable. But with hot air, I've only ended in "dissasters".
Good job keep the videos coming boet
That might have been one of the few times I'd ever pull out the high wattage solder gun for an electronic repair. Just heat the metal case of the jack until the solder points all release. No need to risk surrounding components with the hot air gun and who cares if the plastic bits inside the jack melt a bit. Then again, I have one of those and don't have a hot air station (yet). That unsoldering gun seems to be more of a pain to deal with than a simple solder sucker for a one off repair like this.
Heat the tip of a pair of narrow tweezers and push them into the plastic collar of the broken DC part, let the tweezers cool and then pull them out with the collar attached
Araldite and patience!
nice job! and returning a clean laptop is always a good thing to do.
Had a similar repair come in and the soldering iron hit the superglue and my eyes were instantly burned. Superglue is evil when it's heated. Took a couple of days for my eyes to properly recover. The worst part was i'd already told him not to try superglue and he did it anyway.
why ddnt clean cpu cooling fan ??? 🙄🙄🙄
I wouldn't say that you are way better than me when it comes to solder
I ve seen hot glue being in used to pull things out, hot glue stick itself. Little bit of heating and attaching it to where it needs to be pulled out.
I would have put some 2 part adhesive (glue) on the back of the replacement jack for some extra support.
hey , i have a question -> i have a desktop motherboard and has short circuit but works fine . why has short ? and why work ?
I've made the mistake of burning superglue before. Made my eyes sting.
I wish the US got the big enter key layout.
Blu tac for extracting the broken jack?
Suggestion. Just use low melt solder to clear holes.
Hot glue would work better than superglue. More viscous and easier to clean off any overflow.
I allways use Glass cleaner it have pink color and working great for cleaning laptops
My Lenovo legion 5 although it is a high end laptop it has a soldered dc Lenovo only jack
I wish i had the electronic understanding you have. I have so many laptops that are faulty which could make you rich in fault searching hours. Too bad I'm in a country far away.
I have a question, I build my Brand spanking New computer today, The case is a Lian Li Mid-Tower Chassis, it has a ASRock B450M PRO4 AM4, Pny Cs900 480GB SSD, Seasonic S12lll 550W power supply with a AMD Ryzen 5 2600. I got almost all the part but the ram , I installed all the cords everything single thing that was needed to be plugged into a mother, and for some reason it's power cycling, and when I found the problem, it was the CPU connecter that is plugged into the top-Left of the board and when I take it out the pc stops power cycling, is it because I have no ram because I need help!!
You definitely need RAM in there for it to POST. The power cycling is probably the motherboard trying different settings to detect the RAM - which isn't there.
Hi adam did you do already review of your new screwdriver? Nice video there are lucky that the middle pin is not shorted because then the SIO will be dead
Best regards
Steve
Yea, that review is very overdue. I need to get it online, hopefully next week's video.
@@Adamant_IT ok will be nice.
I've had success with blu-tac
More flux and leaded solder would have given you better looking joints, but who's going to know when its in the case :)
Nice and clean ----- except CPU fan, as someone has mentioned
Yes, always little frustrating when seeing a laptop repair/fix and the fan/dust not being cleaned.
Missed opportunity when you have everything disassembled already.
That CPU cooling fan appeared to look somewhat nasty in my not so humble opinion.
Good day sir i have issue with my motherboard asus H81 gamer its 4 slot memory but only booth with dual channel 16gb but when i put 32gb memory its not booted, could you please advise..i check already thwle pin in motherboard theres no bend pin
Memory type 2pcs of crucial 8gb 2 pcs(1.35v) and 2pcs of samsung 8gb(1.5v) all memory with 1600mhz
Processor- i7 4770
Gpu- rx580-8gb
Psu- 500-gigabyte
Please use your fume extractor on everytime you do soldering.
i have used very thin drill bit
TRY A PIECE OF DOUBLE SIDED TAPE ON A TOOTH PICK AND MAYBE THAT WAY IT WILL WORK.
I love you man
Hot glue may do the trick
The fan was really dirty
its not too bad but worth cleaning
New super hero: Captain Tape...I'll see myself out...
3836 mAh battery on a Laptop? I would be surprised if the backup lasts even for 30 minutes.
Looks like someone attacked the jack with the bloody charger.
"Don't ever do this..." But they will! :) You know why, I know why, probably everyone knows why....sadly they are doing these kinds of things to make sure, you the customer will buy a new motherboard or if it's too expensive, a new laptop. :)
Compressed air from a strong air compressor.
new hot air gun looks sexy
i see he's still using a sata hard drive, not sure how he can cope using one with the internet being so demanding on resources now.
A low end laptop where the entire back comes off ... Is this the norm these days cos it used to be you could only get to the RAM & HDD if you were lucky ...
most cheap laptops now the entire back comes off after removing a few screws so its a lot easier to get into them to work on the mainboard, the con is that its bit harder if you're doing a hdd or memory swap because they don't have the seperate doors which is just 2 scews to remove and you're in
i accidentally fried some lenovo motherboards by forgeting to unplug the battery before connecting the screen flex. other people please always be sure the battery is unplug. you have some balls. i will never do it on purpose.
Buy disoldering wick from nortridgefix
Guys does anyone have a suggestion for antivirus or the windows defender is enough ?
Windows defender will do you fine. I'd also recommend running something like uBlock Origin on your browser, as that'll arrest a lot of known-malicious websites and prevent anything downloading in the first place.
@@Adamant_IT Thank you very much for the answer. Love ur videos keep it up
Admit it um is ok to do hot air on top of a hdd 😫
It's just a piece of metal, there's no hdd components attached to it. I don't doubt it was from a broken one too
My solution is to drop the laptop off a 3 story building, it works…
Good 💩 m8 ,👍👍
The worst smell from super glue :))), you dont have a Fume Extractor?
Get a fume extractor my dude, you’ll thank yourself later.
had to rewind the video to see what the big deal about the fan was and honestly yall overreact for everything, when the fan is filled with clobs of dust then you should absolutely clean it but in this case its surface dust which sticks to the blades like glue, its not pretty but realistically it won't do any harm
Ye it was just surface dust, that powder stuff that needs a toothbrush to get off. Any dust lights up under studio lights though, so it looks worse than it is.
13:33 I like my woman like i like my DC Jacks. Dead flat.
it will certainly damage a motherboard being sprayed onto a device though ;) stop doing that.
Since you HATE the DC connector and you HATE the battery and you HATE low end products
maybe you should only repair high end products.But you will HATE them also seems like you HATE
everything.
lol "I shall make some money" this thing prob isn't worth the repair
Just show us how you did the repair and stop CONDEMNING the products ..If they do everything perfectly it would cost much more and you would have NO work to do ...
Dust man. Dust.
Desoldering guns seem like more work than they're worth. very clumsy and unreliable.
They are worth their weight when desoldering a 24-pin DIP package. Why do you say they're unreliable? Mr. Carlson has been using the same one for decades.

Tbh I think I'm using it in the wrong application. As Mark said, they're very suited for through-hole stuff, but here I was trying to clear very small holes without an appropriately sized nozzle, or that much experience actually using it.
Clearing holes is an acquired talent, and some people make it look very easy. I think the de-soldering gun did help here, but also some of the reason why I demonstrated it was to say "Here's a tool that exists, decide for yourself if you think it's more useful than wicking..."
If you're really good with wick, you probably don't need one of these.
Fake
no u!
Stick a pin.
I just want the viewers to know that ghetto RUclips repair videos like these do not show any type of recommended procedure for fixing electronics. The laptop might work fine for years afterwards, but the product will certainly be damaged in one or many ways. "If you are not doing perfect diamonds, everyone will criticize you..." quote from video shows this guy is delusional. I _wholeheartedly_ support amateur repair, DIY and people fixing their own stuff, but please be real about what it is.
That's incorrect. Videos "like these" frequently DO show recommended procedures, the product is NOT certainly damaged, and the quote from the video DOES NOT show that "this guy is delusional."
@@markanderson2904 Agree to disagree?
I mean, it's a professional repair shop? Short of Lenovo doing a video on replacement, I don't know what you think would be better
So why don’t you show everyone how it’s done instead of just baselessly criticizing others for doing things “wrong” by your metrics?
