The job isn't that tough really. . . . Especially considering the price most shops get to do the repair. Just take it slow and use a digital camera to document your dis-assembly. The pictures will help when you go to re-assemble the computer. When you get it fixed, get a CRD (Cable Retention Device) to take the strain off the poorly designed power pin. Here's a company that makes a nice CRD for laptops.

Just remember, take it slow when you start the dis-assembly process.

It can be fixed but it means removing the original power socket and replacing it with a new one. The socket is usually soldered to the motherboard so the whole laptop has to be dismantled. Most people wouldnt even attempt to repair it and would probably change the motherboard. The socket is available here:

If you can find someone to do the job.

Broken power plugin port


The power plug in port you refer to is the DC Power Jack.

The AC adapter (Charger) converts AC electricity into DC electricity.
DC electricity has two poles. Positive, and Negative.
(Just like on a D cell flashlight battery)

The center pin of the DC Power Jack is the Positive connection.
The outer metal spring-like pieces, on the inside of the cylindrical shape surrounding the center pin, are the Negative connection.
(The pieces of spring-like metal, all connect to the Negative connection in the DC Power Jack)

Example of a replacement DC Power Jack, for the Asus Eee PC 1005HA Netbook,

[ Note*
Cannot agree with the replacement instructions they offer, at the bottom of the page.
Not everyone has access to a hot-air gun. A 25 Watt soldering iron, and Desoldering Braid, is better, and more easily accessed ]

1) Remove ALL power. Remove the AC adapter, (Charger), and Battery.
2) Observe Anti-Static Precautions. Buy, and use an ESD wrist strap.
Electro Static Discharge.

(Average cost is from $3 to $6. Connect the alligator clip to a good ground source.

Power on problem



hello my friend,
Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.

1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.

hope it will help you today.

Battery is showing 100 percent but you unplug power supply computer shut down also when you wiggle cord power shuts down


The DC jack in the computer has detached itself from the motherboard causing intermittent shutdowns, the laptop must be dis-assembled to re-solder the jack back in place, and may need to replace the DC jack if the old one is not suitable.

Power issue Toshiba Satellite m35x-s161


Unfortunately there are many sellers of DC jacks for your model and several others. Some of these people sell sub-standard DC jack replacements which are not designed for your laptop, but will fit in the same hole. If the mount points for your DC jack didn't fit the same pattern as your original one then it simply is not the right jack for your laptop. You can suffer issues such as improper grounding, voltage applied to ground and vice versa with some severe consequences. This can damage not only your charging circuit, but may well cause your battery to overheat and rupture. Remember, that not all DC jacks are designed the same way, In fact most manufacturers design their jacks as different from the competition as possible, whether this is their intent or not is irrelevant. Your Dc Jack, however suffers from the dreaded floating pin problem. The main bullet type pin you see at the middle of your jack tends to separate and spin freely, and can be repaired by simply soldering the pin mount on the back. Try repairing the pin on your original jack and reinstalling until a new jack can be found and I'd be willing to bet your problem goes away.

So far, I've been using an AC power converter for my Toshiba Portégé 3440CT PC notebook that has a round DC plug on the end of the DC cable. This means I have to plug this into the multimedia...


Just for fun I did a Google search for replacement adaptor vendors in the UK. Here are the first couple that came up: one place, another one. You shouldn't have any trouble finding what you need on your side of the pond.

And I have no idea if there's a specific name for that type connector. It's just called "power jack" in Toshiba's parts list.

Will Not Turn on


Which pin did your husband reposition, I assume it was the one inside the laptop. He may not have connected the power switch cable back in properly when he rebuilt the laptop. Ask him to carefully check all the connections by opening the case again. These sort of repairs are normally carried out by experienced tech engineers. Some dc connectors (the bit that the power supply plugs into) have to be resoldered to work correctly or be replaced completely. The fact that you were able to charge the battery means little at this stage I'm afraid. Let me know if you need more help.

Screen black & with no power


hi there,

you can follow this instruction and try to your laptop to resolved the problem.

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with Toshiba Satellite M35X and Toshiba Satellite A70/A75 notebooks. If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it’s still under warranty, it would be fixed at no charge to you.
Problem symptoms:
  1. Laptop randomly shuts down without any warning.
  2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  3. The battery will not get charged.
  4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).
To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. Toshiba Satellite M35X and Toshiba Satellite A70/A75 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system board with a magnifying glass. In most cases you get the power problem because of a bad connection between the DC jack and the system board, you’ll see a crack between the DC jack connector and the system board.
Here is an example of Toshiba Satellite M35X power jack. The crack occurs between the DC jack pin and the system board.
satellite-m35x-crack.jpg satellite-m35x-contact.jpg In some cases the connection is good, but the DC jack is bad itself. You can find a new DC jack for Toshiba Satellite M35X and Toshiba Satellite A70/A75 laptops here. Search for DC jack M35X or DC jack A75.
How to resolder laptop power jack yourself.
UPDATE:
Sometimes, after you replace the jack, you can see that the system board doesn’t get power at all. The battery will not charge and the power LED will not light when you plug in the AC adapter. So, here’s a possible explanation.
When a connection between the positive pin and the motherboard breaks (cracks), the power jack gets loose. You can feel it when you plug in the adapter plug. A loose power jack can damage the trace inside the hole in the system board. Take a look at the picture.
power-jack.gif As you see, the positive pin goes through the hole in the system board and you solder it on the top side. Right? What if the trace between the top side and the bottom side is broken somewhere inside the hole? I’ve seen it before a few times. In this case everything looks nice and clean on the top side. When you plug in the AC adapter, you get normal voltage readings between “+” and “-“ pins on the top side, but the power DOESN’T go to the motherboard at all, because there is no connection between the top and bottom sides. Test with a multimeter if there is a connection between the top and the bottom.
If the trace inside the hole is broken you still can fix it. You can run a wire to connect the top and the bottom sides. Be careful not to short something on the board.
Update:
Here’s another solution to fix the power jack problem, it shows how to relocate the power jack outside the laptop base. Check it out here: Toshiba Satellite A75 failed power jack workaround.
When you repair a loose power jack, it’s a good idea to check the jack on both sides of the motherboard. When you remove the top cover from a Toshiba Satellite A70/A75 laptop you can see only points where the jack is soldered to the motherboard as it shown on the second picture in this post, but you cannot see the jack itself as it shown on the first picture.
Removing the motherboard from Satellite A70/A75 laptop is a good idea because the jack itself might has a broken “+” pin, as it shown on the picture below. If the “+” broke off the base, you’ll have to replace the jack.

Toshiba 9" TV/VCR W/CAR AC/DC - No power when on battery


I would check on the inside for a disconnected wire or loose connection at the Dc imput if it still works on ac. You can most likely get a service manual at http://www.servicemanuals.net/ if the wires are intact on the DC imput and the jack itself fits secure to the adapter. Hope this helps
