Thank you very much for help and reply. Actually one of my friend has got model Latitude 6400, my battery is working and charging very good in his laptop as well as in my laptop. His battery also working good in my laptop as well. I took my laptop to a shop, the technician started working in a hidden place then returend me in a half hour and said pl bring your laptop in a working condition like charge your battery again in your friend's laptop and display should be working good. So its working

Hi, Could you help me please. I was using a broken poorly jointed wires in to the adopter to charge my laptop Dell latitude E6410. The joint was broken and by mistake I jointed it wrongly now battery is not charging at all, even I tried original replicator in which all the laptops are showing charging the battery but in mine one its never charging. Thanks.

@shahmmehmood I think you answered your own question. The problem is not the adapter anymore. Your battery is now dead and that is why it won't charge. If your battery is NiCD and NOT NiMH then you might be able to recover the battery. Look on youtube for "nicd battery fix free" and if that works for you. BUT you must have a NiCD (nickel cadmium battery)

Actually, it's the piece that you are cleaning beginning on or around frame #56 in your video. It's that round piece in the center that the charger plugs into. Once I got down to removing the motherboard, I found that the piece has come completely loose. I don't know if it broke off from the housing that surrounds it, or if it became detached from the motherboard at the point where the 3 prongs touch the board.

[dpblanchard]

I have the same issue as bridgeovertheriver.The inner barrel on the female side of jack came unseated and completely comes out of the casing which is still attached to the board. I already have the laptop taken apart. You mention hot gluing the barrel piece? Can you elaborate? The 3 prongs on the barrel just barely contact the board. Am I correct that these 3 prongs need to be soldered to the board? Or are the prongs soldered to the outer casing, which is itself soldered to the board? Thanks.

[freethrillsdotcom]

@dpblanchard To be honest, I haven't examined the female dj jack that connects to the motherboard. Naturally you should make sure it is soldered to the board. Since 19V is going through it, it shouldn't "barely contact the board" in any regard, otherwise you'll throw a spark and cause a fire hazard at some point. The hot gluing method I was referring to, should be cooler than a soldering gun, and allow you to stabilize the DC jack better since it will get a lot of abuse with use

@freethrillsdotcom re: hot gluing, I would do that inside the motherboard itself. Not exterior to the laptop

Very helpful thnks

Thanks for the video. Would a faulty jack and/or cable connector cause a very slow charge (i.e. 20 hours charge time for 45% battery charge)?

[freethrillsdotcom]

@mtriv111 It sounds like it is doing a trickle charge for some reason. There is no way to figure it out without trying a different adapter, or a different battery. It is quite possible that the battery is faulty. They don't last very long, typically only a couple years. People will talk about how their batteries last longer, but it all depends on usage. Ie: How often you run on battery vs how often you run with an AC connection.

Absolutely brilliant,...followed your instructions and fixed my power supply. My signal wire had broke further down the cable just before the choke (plastic block by the adaptor),.luckily i had a spare faulty power supply which i unsoldered the lead and re soldered into the working one,..Hey Presto,..fully working XPS M1730 again...Sweet.

very good thank you well done, and very informative, you did an excellent job

@freethrillsdotcom I also tried to repair my Dell Inspiron 1520 AC adapter(won't charge the battery). After removing the isolation I couldn't find the red (signal) wire. I would be grateful if you could help me in some way. Here is a photo with the cable: adf . ly/3eKIZ

[freethrillsdotcom]

@htnCosminDan Where did you get this adapter? It looks like it is an aftermarket adapter. Did it have the white waxy coating on it? Looks like a fake DELL clone adapter from that picture. Even if the adapter shows DELL written on it, it could still be a fake unless it is the one you got brand new with your computer.

You're right, without that signal wire, you won't be charging batteries anytime soon. I wonder if is a manufacturing defect? Call DELL too!

[htnCosminDan]

@freethrillsdotcom This adapter came along with my laptop (inside the sealed box). It's 4 years old, but it started making problems about a year a go. So I'm pretty sure it's a genuine adapter. About a year ago it stopped charging, about a month ago it short circuited due to stress at the end of the cable. I opened it and fixed the s/c, soldering the black and white wire back. The only thing left for me to do is to crack open the adapter case and count how many wires are coming from there.

[bridgeovertheriver]

Ok you see at 1:23 that black thing where the charger is supposed to fit in. Yeah well mine fell out. Could you tell me how to put it back or if i need to bring it back to a shop to get it fixed. Thank you!

[freethrillsdotcom]

@bridgeovertheriver If your DC Jack fell out (the middle part), thenit probably will require the laptop to be dismantled completely, and for it to be reseated, re-soldered, and hot glued back into place. Sounds like big job. Find an authorized Toshiba repair center and ask for a quote. Depending on how the damage happened, your home insurance (if you have some) may cover a portion or the entire bill. Our home insurance paid for our laptop repair when we cracked the screen by dropping it.

Comment from MicroCoreSystems : ===> Ok, about that middle signal wire. I have a Dell Laptop which also has a charger like that, but the charger end of the charger is broke...the block thing part of it. What kind of signal is it that the laptop needs just to charge it? is it like a certain amount of voltage or somthing, because i dont want to go buy a new charger, i want to just use another one around the hous, and cut the end off and put this end on it.

[freethrillsdotcom]

@MicroCoreSystems If the signal wire was nothing more than a few volts, then don't you think all the aftermarket manufacturers who make clone adapters would be successful too? There is a reason why only genuine adapters work. I bet it is controlled by a circuit board. It might be time for you to crack open your adapter brick and make a youtube video showing where the other end of the red wire goes.. I think it will go to a circuit board with an IC chip.

Thank you for actually explaining the process...instead of adding music to a very bad video like many other youtube memebers.

thank you!!!!!!!!!!!!!

@3DxReKLeSs a comment like that makes it all worth it. Thanks for letting me know it helped.
