Removing internal parts from a Toshiba Satellite A135 laptop

Toshiba Satellite A135This step-by-step disassembly guide explains how to remove and replace major parts from a Toshiba Satellite A135 laptop.
Very often I get the same question about connecting the wireless card antenna cables to the wireless card. Witch cable connects to witch connector on the card? There are two antenna cables connected to the card. The white cable goes the main connector and the black one to the auxiliary connector. But it should really matter because both antennas are identical.

    Just wanted to say thank you to the author(s) for putting this information together. I was able to fix my laptop by replacing the keyboard, DVD drive and upgrade the memory. I spent about 160.00 in parts and now have a laptop that will run for another 3 – 5 years.

    Thanks again and I do appreciate the information.

    CJ,

    I have a Toshiba Satellite A135-S4447 and my situation is very much like the one described by Sunny in post #29.

    In my case, I bought a Western Digital “MyPassport Essential” 500GB external hard drive with the intention of backing up my laptop before upgrading from Vista to Windows 7.

    Upon connecting the USB-powered drive, it asked me to update to the latest verions of firmware and WD SmartWare software (1.1.1.6 to 1.2.0.7). Both patches were successfully applied and I was able to reboot and then use the WD SmartWare software to back up all docs for two separate profiles. At this point, I tried to unmount the external drive before disconnecting, but it refused 5-6 different times, saying some apps were still using the files on the drive.

    I then used the Windows shut down command, and everything powered down normally. I disconnected the USB cable from the drive to the laptop and went about my business. A couple of hours later, I tried to start up the Toshiba laptop (without the WD drive connected), but it was dead.

    The blue power button light comes on, as do the A/C, power and battery LEDs on the front of the laptop. The optical drive blinks and has power to eject and even spin up inserted discs. However, the laptop does not POST, and neither the fan nor hard drive spin up. No video displays on the screen.

    I’ve tried removing the battery to start on A/C power only, and also disconnecting the A/C and trying to start on battery power only. I’ve tried inserting the Toshiba recovery CD and pressing “C” but of course, there’s no BIOS screen to wait for. Nothing works.

    Is the motherboard toast? A Google search turns up replacement motherboards costing at least $150-200, if that’s what the problem is. Meanwhile, I was at Costco today and saw a Dell Inspiron for $399, including MS Office Student Edition!

    Thanks in advance for your ideas or suggestions.

    Regards,
    Phil

    I have a Toshiba satellite A137-S2346 and I was told that the motherboard had burned out and now I have to buy one and every one that I have seen so far have been over 100 bucks and I feel that if im going to spend that much I should just add some more money to it and get a new laptop please tell me what I should do because I got the laptop from rent-a-center and now that I own it they want me to pay them a monthly fee to insure it and im not giving them anymore of my money times are to hard!

    Sunny,

    After this, the laptop came up fine, and I tried to update the latest BIOS as suggested by Toshiba. The computer froze after the BIOS update and restart. Now, the computer does not even display anything whne powered on.

    It sounds like the BIOS got corrupted.

    Can I buy a generic BIOS chip for this laptop and replace it and will it work?

    Doubt it. I think it’s either to find a new motherboard and replace one with the fried BIOS.

    By the way, try unplugging the AC adapter and removing the battery. Wait for a few minutes and plug it back in. Might help.

    Hi
    I am having problems with my Toshiba A135 S2276 laptop. The boot on password got enabled due to BIOS problem, and I had to drain the CMOS battery as described in one of the articles online by shorting a U shaped pit to the ground. After this, the laptop came up fine, and I tried to update the latest BIOS as suggested by Toshiba. The computer froze after the BIOS update and restart. Now, the computer does not even display anything whne powered on. I can hear the fan, some sound of HD, and I can open the DVD drive some times. No display and no BIOS screen.

    Any idea on what could be wrong here, it looks like BIOS upgrade fried the computer.
    Can I buy a generic BIOS chip for this laptop and replace it and will it work?
    Has the graphics card gone bad?

    What are the troubleshooting tips?

    Thanks,

I tried to use my software (to restore to factory) to bring the computer back up and running but getting message that there is no hard drive and no drivers. Any help will be appreciated. Thanks!

    In other words how do you unplug the DC-IN jack.

  15. 22
    David Says:

    I need to replace the dc power jack but can’t figure out where the disconnection point is on the jack. I know all you need to do is somehow unplug it but I’m not sure how to disconnect the wires from the jack. I’m pretty sure the wires stay connected to the motherboard as I will need those to connect the new jack. Any help would be nice.

    “”I followed all the steps but there’s something holding the center of the case to the bottom around the m k , keys but there’s no screws there and also something right at the middle of where the battery goes but theres nothing there. thanks””

    Im having the exact problem! Anyone help please?

    Did you read through the entire disassembly guide? There is more than one page.
    Did you remove screws hidden under the keyboard?

    Stephen Forbush,

    You might want to check that link out and make the donating process extremely easy or people just might not bother if is to hard to do.

    I’m not sure why you are experiencing that problem. I checked the button and it works for me.

    It should be a 1 or 2 step process.

    I agree. I don’t like how PayPal works for donations, but unfortunately that’s the only option I have.

    Gil,

    After a spill necessitated replacing the keyboard on my Satellite A135, about 1/2 of the keys, mainly on the left side of the keyboard, don’t work. I can’t seem to press the plastic ribbon cable of the new one into the connector far enough for it to engage all the pins. I tried reattaching the old keyboard, but can’t press that cable in far enough either. There seems to be white mineralization on some pins in the connector. It’s a very thin space, and barely accessible.

    Take a closer look on the motherboard. Do you see “white mineralization” on the motherboard? It’s possible you’ve damaged the motherboard.

    I have a problem bios password.How to recover that password…

    Some newer Satellite laptops are know for that problem. If the laptop is asking for the BIOS password you have never set, check out this post.
    My Toshiba laptop displays Password= prompt on startup
    It’s possible that Toshiba will clear the BIOS password at no charge even though the laptop is not under warranty anymore.
