The most solid advice i can give you on this would be to contact the manufacturer of the unit and see what they say is your best choice which really depends on the case type and case dimensions you have, the new board will have to fit exactly into the present case and the ports and card slots etc. have to line up correctly in order for you to use any external devices that you may have or plan to use they can also steer you in the right direction as to the heat dispersal and power consumption of you new board so give them a call and see what they say, who knows it may be a lot cheaper to just replace the system itself rather than spend money on having a new motherboard installed. And if it's still under warranty it would definately be a good idea to see if the present board is defective or buggy!

When i try to boot my toshiba a75 laptop i receive a boot last good ... it won't boot i removed memory module i installed 2 yrs ago and it boots ... i purchased new memory module and get same error- it...


Below are the specs to the type of memory that can be installed in the A75...it is very specific and cannot be anything else then what is listed. You have 512 mb built onto the motherboard, with one expansion slot. That slot can only hold up to 1 gb stick if the BIOS has been upgraded. Go to Toshiba support and make sure the BIOS on the machine is up to date so it will accept the larger stick of ram memory and make sure all the specs are right on the stick that you have.

Each memory slot can hold DDR PC2700 with a maximum of 1GB per slot.*

  • Maximum Memory: 1536MB
  • Slots: 1 (1 bank of 1)
  • Standard Memory: 512, 768, or 1024MB (512MB non-removable)
  • USB Support: 2.x Compliant

    Satellite (A75S206) runs well from outlet but never from battery. Was told that mobo can't accept dc. Need new mobo. True?


    hello loyd516,

    Have you tried a new battery? They are much much cheaper, and a whole lot easier to replace than a motherboard.

    Here are replacement batteries that I found searching with Google.
    http://www.google.com/products?q=Satellite+A75-S206+battery&hl=en

    According to Toshiba, there has been a battery recall for your specific model.
    If that is the case I would definitely contact Toshiba support about it. Maybe you will get a free battery out of the deal. Who knows.
    Here is the link and the list(your model is highlighted)

    Toshiba boots up power light stays on and shuts down, bad m/b ?


    I own a Laptop Toshiba Satellite A75-S2131.
    This series have a problem with the cooling flow to the processor.
    The processor overheats and the laptop shuts down.To solve this particular problem you must tear down the laptop and clean up the processor heatsink (you will find it totally plugged or partially dirty).
    Find in the internet the step by step instructions (with photos) for dismantling this laptop. Do not forget to apply thermal paste between processor & heatsink.

    I hope this solution helps.

    Sounds like a bad hard drive to me. Take out the hard drive completely from the laptop and boot up with the windows xp cd and it should go past the blinking cursor. At that point you know you'll need another hard drive.

    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.

    Beeping power adapter


    The problem is most likely (85% sure) with the DC Jack itself, that is one of the rarer issues with it. Since it is a 2-state switch, the likelihood of both circuits closing is my guess. And also the cheapest repair. I have been completely through the A75 without a schematic, and have to remember it's quirks in design.
