Where is the jack for security lock on toshiba satellite

Call Toshiba

I’m happy to help further over the phone at https://www.6ya.com/expert/wynn_5ba0205233ebfc15

1. Buy a DC Power Jack cable (like this: http://www.ebay.com/itm/Toshiba-Satellite-T110-121-T110-12T-DC-Jack-Cable-/121148410018 )
2. Download and read the manual: http://www.irisvista.com/tech/laptops/Toshiba-Satellite-T110-T115/taking-apart-laptop-1.htm

3. Do the project by yourself or hire a local laptop tech.

Toshiba Satellite laptops often have problems with their power connections becoming loose and losing contact between the positive pin on the DC power jack and the motherboard. Laptops are not designed to operate on the battery when the AC adapter is plugged into a viable power outlet. You will have to disassemble your Toshiba Satellite laptop to repair this problem. This task requires a thorough knowledge of laptop repair and safe soldering practices.

1. Disassemble your laptop according to the instructions for your specific Toshiba Satellite laptop model. Cut the plastic supports off the base assembly with a knife.

2. Cut off the plastic wall that encircles the mount opening with the knife. Extend the circumference of the hole by carving it open with the knife to make it wide enough for the new jack.

3. Bring the ends on the negative lead for the jack together and cover the ends with solder.

4. Remove the original DC power jack and trim the wires from the jack box with the knife, until they sit close to the edge of the jack box. Use the knife to strip the wires. Use your fingers to twist the wires together, and then coat the point where they meet with fresh solder. Locate the positive wire -- it is either red or green. Plug this wire into the positive lead on the new jack, and then find the negative black wire and attach it to the negative lead on the new jack.

5. Place the new power jack in the base, keeping enough extra space available for the plastic laptop cover and right speaker to fit back in later. Cover the negative and positive leads with the electrical tape, and then manually rotate the nut on the power jack clockwise until it will go no further.

6. Figure out which walls will stand in the way of the power jack after you secure the plastic laptop cover. Cut these walls out with the knife. Reverse the disassembling instructions you followed previously to put your laptop back together.

Hi.

Toshiba don't supply service manuals for their laptops. I'm afraid that it is trial and error. You will have to disassemble the laptop without a manual but take note of where all the screws are located. There could be hidden screws also so please take your time.

Sorry I couldn't be of anymore help.


Regards.

I have never heard of anyone being able to fix a bad motherboard other than to solder on a new DC jack which is not what your problem is. You should call Toshiba and ask them if this is a known issue and maybe they will fix it if there is an extended warranty.

when you fixed the jack did U accidently solder anything else to the connector , sounds like a short, causing a ground fault.

I would call toshiba customer support @ 1 800-457-7777. Since your laptop was purchased 10/08 it is still under warranty

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.
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.
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.

well the adapter for toshiba laptop is weak, and the most common method is to use a multimeter with the electroprobes connect to the anode and cathode.if it is normal, the pointer will fix in a short time.
