Can anyone tell me how to replace the dc power jack? I have a new one but can't figure out how to remove and replace.
I'm having the same problem on my Satellite A65-S126, but mine was caused by the laptop taking a tumble. I've opened `er up and put `er back together. when the power plug got knocked in, it knocked off a chip located just behind the plug. This was some time back and I didn't make note of what kind of chip it was, as my soldering skills were ****. I've since done a bunch of practicing and feel up to giving it the old kollidj try, but need to know what sort of chip to pick up before taking the little bugger apart again. I don't want the thing sitting in bits for a few days, as loose parts tend to walk away around here. Bow, howdy.... I wish I'd thunk far enough ahead and just written down what was on the top of that chip.
If you are still in need of getting this fixed I can help. I have replaced many of these DC jacks and have since moved my service to ebay. If interested you can look at the ebay link that I have provided below. This will take you directly to my service ad. As you will see, I am a certified computer technician and on top of that, I have a 100% positive feedback rating. My price is very reasonable as well. So if you would like to get your system fixed, please consider me. The link is:
Thank you and I look forward to hearing from you!

Re: replace dc power jack
To replace the DC jack, the motherboard has to come out. Here's a couple of links that have breakdown diagrams for various machines, you may be able to find a diagram for yours at one. http://repair4laptop.org/notebook.html
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need. goodluck!

When you connect the power, does the charge light lit up? this would tell you the power is transmitted to the battery, wich would mean your DC-jack (where the power goes in) is fine, and the problem might be fixed by:
removing the battery,
remove the power,
hold powerbutton for 20 secs,
re-insert power jack(not battery)
press power on button.
If that didnt work, try the following to determine the DC-jack is the problem:
insert power into dc-jack
gently press the power plug into various directions while constantly pressing and releasing the power button.
at some point the laptop should respond by turning on, meaning that you have a faulty dc-jack, which needs re-soldering or even relacement by soldering to repair.
Maybe you also notice that the power connector is very loose in the dc-jack, this might tell you that the dc-jack is the problem..
If you are referring to the DC Jack..(the port where your AC Adapter Plugs into) then typically No, THey are cheap enough that it is best to replace with new.... Yes they can be repaired, but chances are they won't hold up to the stress, and will just cause problems down the road...
Desolder The Faulty DC Jack... Go Slow, Use Solder Wick/Desoldering Braid... And A Solder Gun...Flip Motherboard to the underside of the DC Jack, You want to put a very small amount of FRESH solder on all Pin ends of the DC Jack - this will allow better flow of the solder when trying to remove...
Then Use The Desoldering Braid and slowly remove the solder from the DC Jack Pin Contact Areas... Do Not Rush or you will ruin the contact pads on the motherboard, you must make sure all solder is removed,,, if you attempt to rip out the jack cause you think its "good enough" you will end up pulling the C ring from the center of the Jack Pin Hole...
Once You Have All Solder Removed Use Some Flux Paste And Again go over each pin to ensure all solder is gone, then you can remove the faulty DC Jack...
Now.. Clean the motherboard where the DC Jack Was... Remove All Old Flux and take your solder gun and go over the Jacks contact pads so that you have fresh solder on all...
Now Add a small amount of flux to all the DC Jack Contact Pads and add alittle to the Pins on the replacement DC Jack.....
Then Solder The New DC Jack Into Place... Solder The BottomSide First... The Pin Ends ..
Then Flip Over and add small amount to the side negative pins and the power pin(s)...
Now you are done..
You can add Some Heat Resistant Automotive Epoxy ( Safe On Electronics) to the sides and back of the new dc jack.... this will double the strength and prevent future damage/wear and tear...
its so easy to write but tell you what its damn hard to do.
you need a very powefull desolder that can reach 350 degrees or else a 150W one.
the trick is to put more solder underneath each hole and so the new solder mixes with the old one and then it will melt.
you need a sucking pipe to **** solder out "without this u cant"
once the old jack is removed its so easy to put the new one and I am not even gona bother tell you how because i am sure you're smart to figure that out yourself, because if u get the old out you can put the new one in.
b very patient, take breaks, dont apply too much heat so the bits near the dc jack wont come off because of the heat.
check that solder isnt shorting with anything else.
Do Not Attemp to Replace the Jack Unless You Have Experience with Soldering... The Original DC Jack Must First Be Desoldered and Removed... You Need A Desoldering Pump or Solder Wick (braid) To Remove the Old Solder From The Jack Post Pins..... DO NOT ATTEMP TO RIP OUT THE OLD JACK!!!!! You Will Pull The Contact rings from the center of the motherboard out and render the motherboard useless...
Slowly and carefully Unsolder the dc jack, Remove it and Clean the board.... Very Important to Clean the Motherboard after desoldering the old jack.... You Must Remove all old Flux...
Then Apply a light layer of fresh solder to all the contacts on the motherboard....
Apply Flux paste to the New DC Jack Pins and a light amount onto the contacts on the motherboard....
Insert the new DC JAck Into The Slots and Apply Solder to all points on the underside of the motherboard....
Flip The Motherboard Back Over, To THe Side Where THe DC Jack Is,, and Apply Flux then a light amount of Solder To The Side Pins and Back Power Pins ...
Then Clean the Motherboard off again using an Electronics grade circuit board cleaner (found at radio shack) or a tiny amount of denatured alcohol applied to a paper towel .. THe Purpose is to remove any remaining Flux..... as this will just deteriorate the New Solder over time unless cleaned off...
Hi, by dc power jack, if you mean the one at the back of your toshiba laptop, to replace, you may have to completely disassemble the unit and expose the back of the printed circuit board. This would involve removal of several small screws, panels, brackets, devices (hd. kb, cd, etc), connectors, cables. The screws would normally be small philips + but others might require a torx driver. Once the back of the main pcb is exposed, you can proceed to desolder the jack. normally there are 2 or 3 solder points. Simply insert the new jack and solder in place, reassemble and that should do the trick. However, if you are not comfortable with disaasmebly and soldering, it might be to your advantage to let somebody technically trained to perform the replacement for you. Hope this helps. Please let me know how it turns up. Regards.
I believe the DC jack is soldered to the board on that model.
It must be unsoldered to remove (from the bottom of the board) and the new one soldered on.
A soldering iron and a solder sucker (to cleanly remove hot solder) can be bought at Radio Shack, HOWEVER if you've never soldered before I would NOT ATTEMPT TO DO THIS REPAIR MYSELF!
It's very easy to toast the motherboard if you don't know what you're doing. I would suggest finding a local electronics/computer repair shop that knows how to work with SMT components. Ask them for an anti-static bag for the motherboard and just bring the motherboard and new jack down to them to have the new one installed. It shouldn't cost more than $40 to replace that way and more like $20-30.
