    Hi Richard,



    Was a 'technician' authorised for Toshiba ?

    Was it done under warranty ?

    If so, try to solve the problem with Toshiba Service.

    How did you 'inspected' the motherboard and find some 'electronic part' is burned ?!??

    I am sorry asking this way, but I am not sure you are qualified for this.

    There is not much you can do this way yourself !

    Now, . . . if your laptop turns on with a blue led and fan 'activity' but no picture, there might be some other reason!

    Is there any 'beep' ??

    I assume you opened your laptop, did you put ALL parts back in a proper way ?

    Did you put the RAM back and in a proper way ?

    (just saw this is an old, 2008 problem)

    Regards.

Try this simple solution. Things get knocked loose all the time. Unplug the laptop and remove the battery. Undo the screws the cover the Memory modules on the bottom of the laptop. Remove then firmly re-seat the cards. Be aware of the retaining clips holding the cards in.

Replace battery, plug in, and boot.

Hope this helps, and you have nothing to loose but a little bit of time.

My laptop wont charge


There's several things that cause this:
- Your ac adaptor could be dead - use a spare one or but a replacement and test. - The power jack on the laptop could be damaged - you need to have a specialist replace this for you - The battery could be dead - test with a spare battery if you have one - If all else fails it means that the motherboard has malfunctioned and needs to be replaced.
It is highly suggested that you bring this system to a professional for repair or purchase a used one with the same specs and swap out your hard drive as it could cost you hundreds to fix this problem. You can buy a used, working one for $250 ob buy it now on ebay, or cheaper if you buy one on a regular auction: http://cgi.ebay.com/Toshiba-Satellite-M35X-S149-1-5GHz-512GB-Ram-60GB-HD-/320664896971?pt=Laptops_Nov05&hash=item4aa91e05cb

DC connector loose in laptop,no power in the laptop


Apparently the DC connector broke. If the warranty is still in operation, have it repaired; else, the damage can be easily fixed by any electronics shop, or even by yourself if you're familiar with a soldering iron for electronics. This guide is for a different model, but the DC section is practically the same in all laptops:

Computer does start up


Does it not seem to get power? This is a common issue with the S149. If you have a charged extra battery or one from a similar Toshiba laptop like the S311 you can see if it starts with a charged battery. If it does the problem is likely the soldered connection on the motherboard for the power cord. This commonly breaks and causes the laptop to not run off the power cord and not charge the battery, but it will run from a charged battery. If this is the case you will need to resolder the power connector to the motherboard. The laptop must be disassembled to make the repair. If you do not have the tools, knowledge or experience to do this or the solder job then you will need to locate a technician that can.

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.

Toshiba M35X


Are you getting voltage from the AC adapter without the jack? I use a paperclip since the probes don't usually fit into the center.

Yes you should have voltage between the terminals on the jack with the ac adapter plugged into it. You may have a bad jack. There are many places on the net where you can get a new jack.

Battery: Fast Discharge, Slow Charge, Charging Lights Flicker, Runs off battery when plugged in


Problems sounds like a damaged power pin from pulling or jerking on the AC cable. I use a Cable Retention Device like the one in this video to keep from hurting the pin.
