If you are good using a soldering iron on a PC board, you can replace the power adapter jack on the motherboard. If not, you should take it to a repair shop and have it taken care of. The cost to have it repaired at a shop should not exceed $50 including the part.

    The adapter part can be found at either Radio Shack, purchased at you local repair center or electronics parts store.

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.

L500D has a broken power supply connector inside the laptop. Is this repairable? Regards, Matt


The 'power supply connector' is the DC Power Jack on the laptop.
DC IN

Repairable?
Yes Matt. Not really that difficult at all.

With most laptops the DC Power Jack is soldered directly to the motherboard.
Not so with the Toshiba Satellite L305 series of Notebook PC's.

The DC Power Jack has it's own cable, which is connected to the motherboard.

The DC Power Jack itself is a small rectangular shape. It slides down into a slot (Trough) made in the outside of the Bottom Case.
The cable leading from the DC Power Jack is composed of four wires, which are attached to a connector,

B) This a link to a free Service Manual for the Toshiba Satellite L500 series of Notebook PC's,

Scroll down to the second Satellite heading.
Begins with - Satellite A10.
Drop down to the second line, go to the right and click on - L500

This is a PDF file. It may take up to 30 seconds, (Sometimes more), for the first page to come up.
It may also take additional time for the file to fully download.
(Page navigation may not be at the top of the PDF file. Hover your mouse cursor towards the bottom of the page)

(Pages 127, and 128 deal directly with the DC Power Jack.
Disassembly procedures begin on Page 121.
Read the Anti-Static Precautions in - Before you begin on Page 129 FIRST )

Observe Anti-Static Precautions
1) Buy, and wear an ESD wrist strap. (Electro Static Discharge)
The average cost is around $3 to $5.
Connect the alligator clip to a good ground source.

{I connect to an unpainted surface, of the metal frame of an empty desktop computer case.
Perhaps you have a large metallic object to use instead. (Unpainted) A large metal serving tray, or large metal knickknack}

2) Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.
{If a multi-compartment container is not available you can substitute with a clean egg carton. Label each egg holder }

Some screws are VERY similar to others. Do Not mix them up.

3) Make a record as you disassemble. Make notes, drawings, and/or photograph/video record.
Nice to have a record to refer back to in case you are interrupted, and have your own personal notes besides the manual, and guide.

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)

Satellite P35-S611 has trouble charging


If you have to wiggle the power cord it is most likely the DC jack on the motherboard. It is usually the center pin in the the jack that breaks the solder point and the small tension band inside the jack housing weakens.

My battery doesnt hold a charge


That means that you will be needing a new battery. I would suggest that when you get a new battery (hopefully from the manufacturer) What you should do it charge it, and don't recharge it untill it has completely dead. That will help to preserve the battery longer.

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.

DC JACK FOR Toshiba Satellite P35-S611


You will need a small set of screwdrivers, flathead and phillips, a pair of pliers or nut drivers, and a soldiering iron. A magnetic screw tray is also handy with all the small screws. You will need to completely disassemble the machine and remove the motherboard. If replacing with a new jack you will then need to heat up the soldier holding the jack in place to remove the old jack, then heat and clean out the old soldier from the hole the jack pins fit into. Soldier the new jack into place and put it all back together. I believe the P30 and P35 are basically the same machine, here's a link to disassembly instructions for the P30.

Display problem


Wiggle the power wire slightly. Sometimes if the connection is loose it may cause the computer to go from battery power to ac power.

If that doesn't work, could be a loose connection in screen or a part is failing. Would take to a local repair center to check out.
