    I didn't want to step on Annas' electronics thread. I have a Toshiba satellite L655D-S5050 that quit working just after the warranty expired. The shop said the motherboard was bad. I was playing around on ebay and found all kinds of motherboards and all kinds of prices.

    I took mine apart got the motherboard out and went back to ebay. There is a number embossed on the board just below what I think is the memory card. I have found some boards with similar numbers, none that are the same. The pictures look just like mine. How do I tell which ones will work.

    I readily admit that I am way over my head here, but figured that a little education might be worth time it took to take it apart. Here is a picture.

    Confident in the guy that made the diagnosis. A new motherboard is just short of $300 from Toshiba plus installation. Wasn't worth putting that much into a $450 laptop.

    I was packing up my den getting ready to move, when I found it laying where I left it last summer and got curious/adventurous.

    If I can't fix it I'm not out anything but a little time, and I drank a beer or 2 while taking it apart so the time wasn't really wasted either!! :D

    A little more ebay research makes me think the difference in the ones listed there is what processor they have. Mine is an Amd Athalon II. Most of the ones on ebay seem to be intel.

    Thanks for the reply c3 the link you attached is one I hadn't found.

    I can't seem to attach the ebay link to what I found

    Can you install a better motherboard?

    Friends mom back in the day dated a retired dude from nasa when I lived in Huston. Tore apart some old desktop and installed a windows 99 motherboard and all that jazz. It worked.

    That is the problem, I know so little about computers that I don't know what others will work. I don't need anything special just do my banking and hangout here and a few other forums. Occasionally google something.

    I go through laptops fast.

    One trick I have learned is

    you pay about 25 cents on the dollar

    for a laptop at a pawnshop. And they will

    usually throw in a case for free...

    If you were to replace the motherboard with any other model you would have to re-install your operating system. The OS on your HDD already has all the drivers loaded for the original MB. Therefore it would not boot up with another model. You would lose all your personal files. One solution would be to access your hard drive with another computer and copy your files before re-installing the operating system on the replaced (other than original MB).

    When this computer quit working I pulled the hard drive out and bought a case for it. I was planning to use it to back up the new one after loading the files from it to the new one. I haven't actually backed up anything yet though.

    HDD = hard drive?? Is the operating system in the hard drive or is it somewhere else on the mother board?

    If I understand you right I need to find one with the Amd Athalon II processor and has the same number next to the memory card. That number is DAOBL7MB6DO REV D the Os may be zeros, or my hard drive won't be able to wake it up.

    Yeah, HDD = hard disk drive. And on most computers the OS is installed on the HDD (an exception would be recent high end machines that have a SSD, basically a flash ram drive). Putting the laptop HDD in a case, as you did, is a good way to move your data to a new computer.

    Installing a motherboard in a desktop is physically easy if both are industry standard architecture and roughly the same vintage. Laptops are proprietary and may change year to year so there could be trouble just getting the board to fit much less work. I'm confident replacing motherboards in desktops but with a $450 laptop that dies a few years down the road, I'd be looking at a new one. If you want to dink around with it and motherboards aren't too expensive, go for it. But watch out, you can get too much money invested in an old machine when the newer, faster one doesn't cost much more.

    I have replaced it with a hp I just thought I could educate myself a little bit and maybe get it working for my daughter to use. You are right at the price of the lower end ones it doesn't pay to put much money in it, which is why it was sitting in the den for 2 years.

    The motherboard is out and I am pretty confident I could install a new one exactly like the old one, but making the wrong one fit or work is totally beyond my abilities. Thanks for the reply.

    You know, there are PC forums and even laptop forums. You might lurk a few to see which ones are strong in hardware, then join and throw out this question. You may find someone who knows your Toshiba inside out and which motherboards will work. The right Intel boards should fit too but that's the trick, finding out which fit.

    Earlier it was mentioned that Windows configuration on your HDD may not like the new hardware. But it should boot in Safe Mode and then you can add the right drivers but not from the Internet as Safe Mode just brings up basic functions. With your new laptop you could get the drivers and transfer them to the old laptop via a thumb drive. Anyway, unless things are radically different you shouldn't have to reinstall Windows. Another complication is Windows may need reactivation and you may have to explain to Microsoft that you're not moving Windows to a different computer, just replacing the motherboard.

    Changing the MOBO is not like changing a HD. First you have to find the exact board for your laptop. Modern motherboards are all in one MOBO's. In other words all the parts your computer needs to function come on the MOBO, which further complicates installation.

    Find another computer. It's time for you to meet mr windows 8.1.

    As above by the time you buy the specific parts to repair you'd probably do better going for another machine. I needed a laptop for my shop so went on ebay and in computer parts they have some machines that were retired without HDD and or other parts (missing parts) Bought a Dell 620 without hard drive and caddy for almost nothing. It had the windows logo sticker on back with os serial so no problem buying a drive and reloading the os. I think I had around a hundred in the whole thing. Just loaded win 8.1 into it and have no complaints about its performance. Hope this helps.

    I kinda figured this would be the case. One of those things that "seemed like a good idea at the time" I don't really need it just thought it was worth a try.


    You mean " if you ain't the lead dog the view never changes" ??? :D
