    just to clarify, what is the power supply that you are using?
    I thought I had a dodgy socket, went thru the trouble of replacing said socket on a different model laptop. It turned out that the 3rd part psu I was using had a design fault in that the adaptor, after a while lost contact with the power cable on the psu, causing laptop to shut down.

Is there a specific part that allows power to all parts of the laptop. mine wont power up everything all the time and sometimes it does


The power supply but that most likely isn't your problem.
Usually the problem is where, over time, the power adapter jack that plugs into the laptop has a broken wire and it will sometimes make contact and sometimes not. Eventually it will completely break and not work at all. Some folks have to put a book or some support under it to keep contact. Other times it is the socket in the lap that the jack plugs into; it likewise develops a bad connection. Google this, and there will be lots of hits on how to repair. It may involve opening up the laptop. Look for Youtube videos also.
If you lap is still under warranty, this should be covered.

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

When plugged in the unit starts to smell hot like an electical burn,


Turn it on turn it over and see if the fan is operating. If not power your lap top off and replace the fan. You may have to not use this computer until the fan is replaced it is advisable not to. The smell you have may be dust smell when it gets hot. Clean throughly and make sure that all the dust is out of your computer. Also recommended a lap fan also which goes underneath the laptop to assist with cooling.
Lap tops are very touchy and need to be kept cool at all times otherwise you will be purchasing a new lap top if you do not take care of the cleaning or the cooling or the fan not working or spinning slowly. Check all this out. Critical if you do not understand what I mean take your computer to a local shop for immediate care. I hope this assisted you. John

How do you replace the power jack socket?


Hi there,

I'm a laptop repair specialist. The DC Power Jack is soldered to the motherboard. While I am able to do this repair I no longer take the trouble because there are many vendors on eBay who perform the service for half, or less than half, of what I'd have to charge a customer.

Go to eBay and in the search window type in "Laptop DC Power Jack Repair". You will be re-directed to a page with many choices of vendors where you simply send them the laptop and they return it repaired. You should expect to pay between about $85 to $125 including all shipping.

Take care,

How do i replaced the charger socket in my l300d toshiba laptop


I have come across this issue in a number of Toshiba laptops recently. The DC jack assembly (which includes a wiring harness and the DC jack) actually breaks away from the bottom laptop housing. What I have done is to glue the jack back in place using a hot glue gun. You need to be careful and observe how the right speaker (located on the top housing) is situated. Be liberal on the glue and make sure the jack is encased in the glue. I have not had any units returned after this was done.

Good luck

sounds like the power jack at back of computer has gone bad, check voltage of battery and see if it has good power if not then it is dead and not getting charged through port the jack at rear generally requires MB replacement and is very expensive and cheaper to get new laptop, u can remove HD from old lap top and copy data over. another choice is to get stand alone charger for laptop battery and use battery mode,

if battery tested good them there is slight chance power switch is bad

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


You need to have the brand, model number ready so I can look it up, but first check with the factory so you don't void the warranty, you might be able to turn in your laptop and get it repaired for a small amount instead of having to take it apart and re-sauder it.

I hope this helps
