Today I explain how to repair a damaged power connector also known as power jack in Toshiba Satellite L305 and L355 laptops. I started covering this problem in one of the previous posts.
Also this power jack modification should work for the following models: Toshiba Satellite L300, L305D, L355D, P305, P305D, Toshiba Satellite Pro L300, L350 and probably some other Toshiba laptops.
PROBLEM DESCRIPTION. The power jack gets pushed into the laptop base so it feels loose.
I will replace the original plastic jack with a generic metal jack purchased at RadioShack for about $3.
The RadioShack part number is 274-1576. This jack is designed for tip size 5.5mm O.D.x2.5mm I.D. You can order this jack online or pick it up in a local store.
Proceed on your own risk! If you do something wrong, you can damage the laptop.
In order to access and repair the power jack it’s necessary to disassemble the laptop and remove the top cover assembly (palm rest). Here’s an example of removing the top cover assembly from a Toshiba Satellite L355D, you’ll have to follow steps 1-14.
Disassembly steps for all above mentioned models will be very similar.
OK, let’s say the top cover is removed and we are inside the laptop. By the way, I’m fixing a Satellite L305D laptop.
Why the power jack feels loose? You see the answer on the picture below.
In my case both, the power jack and mounting brackets on the base assembly got broken. Even if you replace the broken jack with a new one, it will not stay attached to the base. If you send a laptop with a damage like that to a repair shop, they will recommend replacing the power jack harness and laptop base. This repair will easily cost over $200 but I have a better idea how to fix it for $3 without replacing the base assembly.
Here’s my new replacement panel-mount jack which should last for a long time unlike the original Toshiba jack.
All laptops mentioned above come with one of the following AC adapter: 19v-3.42A, 19V-3.95A, 19V-4.74A or 19V-6.3A.
All these power adapter will fit perfectly into the jack from RadioShack.
LET’S START THE REPAIR.
STEP 1.
Using a pocket knife remove plastic supports from the internal side of the base assembly, so the side where the new jack will be mounted is flat.
On the picture below you see plastic supports removed.
STEP 2.
Again, using the pocket knife remove the plastic wall surrounding the mounting hole. Make the hole larger, so then new jack fits in.
STEP 3.
The new jack is too long and if you install it as is the laptop cover will not sit properly on the base. It happens because one of the speakers (in Satellite L305D) is located very close to the power jack.
It will work if you make the jack shorter. You can cut off part of the long “-” lead or simply bent it as I did. After it’s done coat both leads with generous amount of solder.
STEP 4.
Now remove the damaged power jack from the laptop and cut off wires somewhere close to the jack base.
Remove insulation, twist wires and coat them with solder.
The red “+” wire will connect to the lead in the center of the new jack.
The black “-” wire will connect to the lead on the side – the one you made shorter.
In some laptops Toshiba uses green wires instead or red wires. They also should be soldered to the “+” lead in the center of your new jack.
WARNING! Check the polarity before you apply power to the laptop.
STEP 5.
Now mount the new power jack on the base.
STEP 6.
Solder wires to the new jack. Again, the red wire is soldered to the lead in the center and the black on to the lead on the side.
As you see, I soldered wires at a 90 degree angle to the jack so the top cover (and the right speaker) fits in.
I covered both leads with electrical tape.
The new (modified) power harness has been installed into the laptop base. Now you can tighten the nut on the power jack and secure it on the base.
STEP 7.
You’ll have to modify the top cover assembly a little bit so it fits on the laptop.
Remove plastic reinforcement walls so they do not touch the power jack when the cover is installed. If you leave these walls, there will be a gap between the cover and base.
The plastic walls have been removed.
STEP 8.
Assemble the laptop. You are done!
I think the new power jack is way more robust then the original one and should last for a long time.
And it looks great too.
Here’s an example of damaged power jack in a Satellite L355D laptop. This base is bigger than in Satellite L305 and you’ll have plenty of space for your modification.
Here’s another example of damaged base assembly in a Satellite P305D laptop. Again, there is plenty of space for the jack modification.
By the way, if your laptop is still under warranty, Toshiba might fix this problem at no charge. Call them first or take the laptop to the authorized repair center.
If this modification works for you, please mention the laptop model in the comments. You are welcome to post any suggestions and improvements.

Do I have to take apart the motherboard? like step 14 says?

Great fix! I noticed that my power socket was loose and found this article. I was wondering how tight the socket is from new as i only have about 1mm of play up and down and about the same left to right with no movement in and out. Even with firm pressure the socket feels secure. I originally thought the socket was soldered directly to the board so any movement was bad news, but looking at the design i’m thinking that it might be normal. Any thoughts?

I have an A305 satellite laptop. It will only charge if you push the adapter in real hard and hold. I disassembled and discovered the dc jack is broke off from the plastic guides. Since it will charge if pushed in hard enough, is this a power cord connector issue or the jack? I bought the parts to fix this with the co-axial solution, but am wondering if I might still have the same problem after doing this. Any suggestons?

just applied to daughter’s Equium L350-10L (UK). She needs to use for school so unable to fit replacement power socket tonight., but Maplins JK10L at £1.59 is the UK equivalent and only needs an 8mm hole and is smaller overall @ 11mm dia and 21mm long.
As a temp repair, the locating lugs were not broken and I’ve rotated the existing socket thru 180 and refitted and put a brace section (modified an old desktop card blank cover) to provide support should she put too much pressure on the power lead when connecting. All rebuilt and working fine now; battery charging nicely.
Great info and descriptive pics; donation on the way. Will definitely use the site again (now a ‘favorite’. Thanks and keep up the good work.

Never mind

Any chance this will work with A205 model?

BliND,
I guess your soldering gun is not power enough. When I soldering the jack I didn’t have any problem. Make sure to use rosin-core solder.
Quote from Answers.com: “Solder made up in tubular or other hollow form, with the inner space filled with noncorrosive rosin flux.”
You can buy rosin -core solder in Radioshack ( Catalog #: 64-013 ). This solder will stick way better.
1. Unsolder wires from the jack.
2. Clean up contacts on the jack.
3. Apply a think layer of solder before soldering wires.
4. Solder wires.

Ok, I figured it out. I guess it was just my soldering cause I redid it again this morning and it worked for a while, but again it stopped. Could I like cut some notches or drill a hole on the middle pin for the solder to stick better on it cause I’m pretty sure if I open the laptop again it probably came off. And really, thanks a lot for this guide!

BliND,
Toshiba will not fix the motherboard, they will replace it with a new one. A replacement motherboard for a Satellite L305 will start from around $200. Plus you’ll have to pay labor charge. If you send this laptop to Toshiba, I would say you are looking at about $300. But call them and ask.
Send it directly to Toshiba (not authorized service center) because it might be cheaper.

Well, we did have trouble soldering the middle pin, it was kind of hard getting it to stick to that smooth surface. I used a multimeter to test if power was going through and it was so I guess it is now a motherboard problem. Any idea how much a fix like this would cost without warranty through Toshiba?
