This is a very common complaint for Satellite laptops of that size. There are 2 potential solutions for this based on what hardware you have. The DC input can either be soldered to the motherboard, or screwed down. Both options will require you to disassemble (and thus void any warranty) your laptop. If it is under warranty, I'd work with Toshiba to get it repaired/replaced. Their support phone # is 1-800-457-7777.
If you are comfortable disassembling your laptop do the following:
1) Unplug the laptop from power and remove the battery.
2) Remove screws/bezels/keyboard and other devices from the frame until you can see the DC input connection to the motherboard. The will generally look like this: My dc jack in my - ccws.jpg
3) The 2 prongs on the inside will be connected either to cables or soldered to the motherboard and the plastic frame of the plug will be screwed down or held in place by the soldering on the 2 connectors. If it is screwed down you will likely see that the screws are lose, tighten them and the issue should be resolved. If it's soldered I would carefully repair the broken solder connection ensuring that no other circuitry is connected to the joint.
4) If these parts are all tightly fastened but the inside of the connector is the only part that is lose than I would recommend replacing it. The image above is borrowed from http://laptoppowerparts.com and I've used them many times to get replacements for this issue. Once you've secured the proper replacement part (http://laptoppowerparts.com will help you find the right one through online chat or a phone call) you will need to install it/solder it in.
I hope this helps!

Check with the manufacturer if there's a recall with the product.

Plugged in not charging


There could be several things wrong. You could have a broken DC jack on your motherboard. To prove this, wiggle the DC jack with the adapter plugged in. If the charging light comes on when you wiggle the jack, then your jack is broken. You could also have a defective AC adapter.

Will not charge


laptop plugged in not charging:

1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.

2. Make sure your toshiba power cord is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.

3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.

4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.

5. The power button could be bad

6. The motherboard could be defective & needs to be replaced.

My laptop charger is not working


Two possible causes:

1)your laptop charger is dead or malfunction

2)your laptop dc jack is loose or malfunction

If you need to turn around your charger at one position so that the laptop will charge, that means your dc jack is dead. Otherwise your laptop ac adapter should be replaced.

If you need to purchase a new toshiba charger, you may click the following link to take a look at Toshiba Satellite M30 AC Adapter:

Connecting charger and letting charge for sometime...charging light doesnt turn on and laptop doesnt turn on...any advise?


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

My toshiba a 205-s5825 satellite wont power upo and no lights nothing


The problem is in the power supply adapter, or the dc jack in the laptop is loose, if you move the cord from the power adapter to the computer and it comes back on then it is more than likely the dc jack in the laptop that is attached to the motherboard. The remedy is to replace the dc jack or resolder the old one, in order to do this the computer must be taken apart down to the main board for service.

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.


I guess you've got a broken laptop power dc jack or power cable.


Symptoms of a broken Laptop DC power jack:


- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

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.
