The most common problem on these units is the ac connector solder joints break away from the motherboard. If you're sure the ac adapter is working, and the correct one, and it's not charging the battery (assuming the battery is good), it's most likely the problem. They don't have to appear loose to be loose.
Otherwise, it's motherboard time, or a loose screw, etc has caused a dead short on the board.
Good luck, if you have additional info, let me know.

Those cables are custom made for each manufacturer and model. The only place to get a replacement (other than buy a junker on ebay) is from the manufacturer. The plastic pieces are another matter. They are standard connectors and you can buy them from Digikey or Mouser. Soldering them in place is not for a novice. You need a proper soldering iron, desoldering tool, very fine solder and a lot of patience and skill.

I suggest you replace the motherboard. A recent search on ebay turned up three ranging in price from $18 to $85. Soldering a motherboard by hand has a very high failure rate. It's easy to bridge or scratch something and fry the board. You could of course try to do it and if it fails get a replacement board.

Loose power connection on motherboard of Satellite L640D-ST2N01


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.

Engine will not start


Around this shop we diagnose, and not assume.

1) Test the AC adapter (Charger)
Test with a multimeter set to DC Voltage. You should read VERY close to 19 Volts. (DC)

While testing have an assistant gently wiggle the power cord TO the AC adapter, and the power cable coming FROM the AC adapter.
See if there is an intermittent reading for either one. Indicates a break in the wire/s.

2) AC adapter checks out OK go to the DC Power Jack. This jack is the port on the side of the laptop, that the AC adapter plugs into.
(DC IN)

Remove the Battery, see if you can gently wiggle the Center Pin. Use a non-metallic object, or tool.

Also check if the metal shell inside the DC Power Jack moves around.
ANY perceptible movement indicates a problem with the DC Power Jack.

Fortunately, for this model the DC Power Jack is a Power Jack Harness,

http://www.lapdiy.com/toshiba-satellite-l305s5941-power-jack-wire-port-dc-in-cable-p-7556.html

The jack portion is a squarish shape with a channel formed around it, and sits in a cutout formed in the outside edge, of the Lower Case.

The harness coming from the jack has a plug on the end.
You just unplug it, and plug a new one back in.

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L305-L305D/big/remove-lcd-screen-replace-video-cable-09.jpg

In the photo above, it shows a Toshiba Satellite L305 series Notebook PC, partially disassembled.

On the right side you see the optical drive. Squarish shaped with one corner gone. Has a large white label on it, with a smaller yellow rectangular label.

To the upper right you can barely make out a Red wire. It is connected to the black DC Power Jack.

Looking straight across from it to the Left, you see the other end of the Red wire connected to a white plug.

That's the DC Power Harness, and where it plugs in.
This is the entire article,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-L305-L305D/remove-screen-replace-video-cable-2.htm

(Page 2, and 3 is listed at the top, and bottom of the page, in white.
Page1::Page2::Page3::Find another model )

Posted to show the DC Power Harness, and a pictorial guide that I feel will help get you started.

3) Power Button Board:
Has the Power On switch on it,

http://www.laptoppartsexpert.com/i-7600699-power-button-board.html

If the Power On switch is working, the laptop isn't going to turn on.
('Natch)

See the two wires coming from the board? Black and Red?
Red is the Positive wire, Black is the Negative wire.

Unplug the Power Button Board's plug to the motherboard. There are 2 pins. Carefully touch a small flat tipped screwdriver, (Jewelers is recommended), BRIEFLY to these 2 pins.

Laptop comes on you have a bad Power Button Board.

4) If none of the above is the problem you have a bad power sensor chip.
It's a Power MOSFET.

http://en.wikipedia.org/wiki/Power_MOSFET

Soldered to the motherboard, and takes skill to replace.

(It's a power transistor that is used in the circuit.
Need to use Heatsinks on the J type leads when replacing, and good skills for un-soldering/soldering.

But doesn't take a rocket scientist to replace it.
{ Sorry Gort }

This example is used in a LOT of laptops,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

Intermittent power supply, problems whit the jack, how I can change that? thanks, Ing. Elton Vargas


1) Check to make sure the problem isn't the cable going into the plug, from the AC adapter. (Charger)
A lot of times, where the wires meet the back of the plug, that goes into the laptop DC Power Jack, is bad.
The wires have a break from becoming stretched. Makes an intermittent contact.
Same thing for where the wires meet the charger body.

AC adapter plugged into power, unplugged from laptop, use a multimeter set to the DC voltage scale.
Use the alligator clip attachments for the probe leads, attach the probe lead's to the AC adapter's plug, and wiggle the wire, check for an intermittent break.

2) AC adapter (Charger) unplugged from laptop, Battery removed, see if you can wiggle the center pin of the jack.
You may find the entire DC Power Jack will move a little.

If the center pin does not move, but the entire body of the jack does, the jack may just need to be
resoldered to the motherboard. The solder connections may be cracked.
If the center pin moves, replace the jack.

To replace the DC Power Jack, or repair the solder connections,

1) Remove all power to the laptop. AC adapter and Battery.

2) Observe Anti-Static Precautions:
Buy and wear an ESD wrist strap. (Electro Static Discharge) Connect the alligator clip to a good ground source. I connect mine to the metal frame of an open, empty desktop computer case.
(You don't need an Anti-Static Mat)
The price of an ESD wrist strap is around $3 to $8. Found in a multitude of places.
Example,

http://www.costcentral.com/proddetail/Cables_Unlimited_Anti_Static_Wrist_Strap/ACC1400/10720671/froogle/

3) Completely disassemble the laptop down to the bare motherboard in your hand.
No Processor, Heatsink assembly, peripherals, nada.

TIPS:
A) You may wish to take photos, or make a video as you disassemble, for your first time. Also make notes.
After the first laptop the next one becomes easier.
(All of them follow a basic path when disassembling. Toshiba, HP, Acer, Gateway, you name it)

B) Use a multi-container for the various screws. Label each container for the area the screws came out of.
There may be 60 or more screws, and 12 different types of screws. Some look VERY similar to each other, but are NOT. DO NOT mix them up.
You can use a clean egg container in a pinch. Label each egg holder.

C) Take your time, use patience. Practice your soldering, de-soldering skills before working on the Toshiba's DC Power Jack, if you're rusty.
Use Desoldering Braid, and not a Desoldering Tool. (Solder S-ucker) The desoldering braid works MUCH better! (Also known as solder wick)

How to replace dc power jack for toshiba p15


Take apart laptop and see what type of jack is on your system. There are two types. one is soldered on and the other is a module that connects to the motherboard with a wire connector.

If you have a soldered on type the you will need to de-solder it from the board then solder a new one onto the board. most ac jack issue just need to resolder it unless the jack itself is broken.

Satellite l305-s5907 is plugged in but there is no power light on the front and it will not do anything


This sounds like it may be a DC power jack or the AC adapter. Did this happen suddenly or did it occur over a period of time? Have you had to jiggle the AC plug to get power? Look to see if the pin is broken off of the jack inside the plug hole or if it is loose when you plug it in. Or was the cord yanked on? If it did happen suddenly it could still be the DC power jack. They can go out by an arc of power and melt a nearby chip etc. or the jack plastic itself. If you can get intermittent power by moving the tip then it is almost surely the jack. I don't suggest continuing to do this as it will just make an inevitable repair worse and maybe even ruin your MB. You can also look at the AC adapter (unplugged to be safe). Check where it connects to the tip and goes straight to the plug. There is a flexible part there. The check the flexible parts of the cable near the adapter brick on both ends. If no luck it will need to be opened and have the jack looked at first then if that isn't it the MB. Make sure if you bring it somewhere they don't tell you it is a bad MB when it is a jack. One important note. This model has a DC harnessed jack meaning the DC jack isn't soldered to the MB but rather sits in a bracket and has wires that are soldered to the back that then go to a clip that connects to the MB. Often these wires break loose from the jack and just need to be soldered back on. Toshiba is sneaky with some by making the wires hidden inside a "secret trap door" so you can't see where they are soldered or if they broke loose. You can pop this plastic off the back and check the connections and often re-solder them back on. Use heat shrink over the exposed wire if you have it and put some epoxy over the connections and you should be good. Even better than new often.

The pc not turn on, no power


It might be an issue with the adapter, the battery or the AC jack on the motherboard. First up see if your AC adapter's power LED comes on when plugged into a power source. If it does, then check if the Lights at the front of the laptop indicate that the adpater is plugged in. If they light up then it means that the laptop's battery is faulty and needs to be replaced. If the lights dont light up then it means that the AC adapter jack on the laptop has bad solder joints and/or damaged. It is located at the underside of the motherboard where the AC adapter is plugged in. You will need to take the laptop apart and re-solder/replace the jack.

Let me know if you need more help,

Toshiba plug-in ac adapter LCDlight flashing and wont boot up


It may be that you need a new, (Or good condition used), motherboard. You may not.

The problem could be the DC Power Jack. The DC Power Jack is small, and the body is made of plastic. Sometimes there is a metal shell around the plastic body. (The jack is a rectangular shape, and is just a little larger, than the outside portion of that AC adapter plug!)

This is an example of a DC Power jack for a Toshiba Satellite a215-s5807,
http://www.notebookworks.net/ProductDetails.asp?ProductCode=NBW52-0133

As you know there is a metal pin in the center, and at the back of the round hole, there are flat metal contacts.

Let me explain the construction of a DC Power Jack, and how it's mounted to a motherboard. This all has relevance to the solution.

Your laptop uses DC electricity. (The AC adapter converts AC to DC. Your laptop battery, and a flashlight battery, are examples of stored DC electricity)

DC uses a Positive connection, and a Negative connection. The metal pin in the center is Positive. The flat metal strips at the back are Negative.

That laptop DC Power Jack has metal prongs, that come out of the plastic body. One prong, (Or pin), connects to the Positive metal round pin, in the center of the jack.
There may be one, or two prongs, (Or pins), that come out of the plastic body, and connect to the Negative side of the jack. (Flat metal strips)
These prongs go down through holes in the motherboard, and are soldered on.

With the AC adapter plugged in, an accidental bump on the plug itself, could break the body of the jack, or break solder joints that hold the jack to the motherboard.

AC adapter removed, and battery removed. Use a NON-metallic object, and see if you can make the center pin of the jack move. See if the entire jack itself seems to move.
A.If the center pin moves, you have a broken DC Power Jack.
B.If the entire jack moves, you have cracked solder joints. (Broken)

Replacement of the DC Power Jack for A.
Re-solder the solder joint/s for B.

Cost of replacing a jack at a reputable computer repair shop? $90 to $150
Cost of re-soldering solder joints? $50 to $90
Cost of replacing the motherboard?
$250 on up.

If you are a skilled person with the correct tools, it is feasible for you to replace the jack, or re-solder the solder joints.
It is also feasible that you yourself, could replace the motherboard.

Some laptops have a poor motherboard design, for where the DC Power Jack is mounted to the motherboard.

Crude explanation would be, that the main body of the motherboard is a 1 foot square. Then a 2 inch square comes out of the side of the main body.
The DC Power Jack is mounted to that 2 inch square. From accidental bumping, OR just normal usage of inserting, and removing the AC adapter plug, this 2 inch square can crack away from the main body.
This, of course would require a motherboard replacement.

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.
