    • We will disassemble the Toshiba Satellite L645D-S4056 and remove the motherboard.

    • Have a small flathead screwdriver and Phillips head screwdriver available.

    • An anti-static wristband is recommended.

    • Have a way to keep your screws organized. I use an ice cube tray. I tear off pieces of scratch paper, and label them to where the screws came from.

    • NOTE: The screws are magnetized, reducing the risk of them falling into the machine and being lost. They will stick to the screwdriver upon removal.

    • Flip the laptop over so that you are working on the bottom of the machine.

    • Unplug the A/C adapter from the laptop and the wall outlet.

    • Next, we are going to remove the memory modules.

    • With the laptop still flipped over, locate the "L" shaped panel.

    • There are 3 screws that hold this panel in. Use your Phillips head screwdriver to remove them.

    • Once the screws are removed, used a flat head screwdriver or fingernail to lift up on the notch and remove the panel, exposing the memory modules.

    • NOTE: The screws holding the panel in do not come out the whole way. They just loosen up enough to remove the panel.

    • On each side of the memory module, there are silver arms locked into notches on each side of the memory.

    • Pull them away from the memory module to unlock it.

    • Your memory stick will stand up at an angle, once both sides are unlocked.

    • Pull up on the middle of the memory module and remove it from the slot.

    • Repeat this process to remove the second memory stick.

    • There is a small screw located just above the memory slots, beside the barcode label.

    • Remove the screw, and push the silver piece under it towards the barcode label.

    • The optical drive can now be slid out from the opposite side.

    • Remove the two screws.

    • Lift and pull the wireless card from its slot.

  7. Disassembling the Toshiba Satellite L645D-S4056: 手順 7、 1の画像 1
    • Use your flathead screwdriver to pop the CMOS battery out.

    • After the bezel and screws are removed, lift up on the back of the keyboard. It should lift freely.

    • Follow the ribbin cable to the blue connector on the laptop.

    • There is a black bar that runs across the top of the cable.

    • You should be able to flip this up with the tip of your finger into the unlocked position. If not, gently flip it upward using your flathead screwdriver.

    • Identify the speaker cable.

    • Pull the speaker cable from its pin connection.

    • Lift and remove the top cover.

    • NOTE: Do not pull hard or pry at first. If the cover is difficult to remove, be sure that you removed all screws. If so, then do not be afraid to GENTLY pry with your flathead screwdriver. You may have to tug or apply gentle force to get this piece off.

    • For me, working one of the corners up, then sliding my finger between the top and bottom pieces of the chassis along the edges worked flawlessly. Try not to scrape any internal parts when you do this.

Great guide, it's not the exact model I have but this guide allowed me to take apart and fix my laptop much quicker knowing where most of the screws were. Thank you!

Great write up. One recommendation: overview photos of the case disassembly showing where screws are on the case, in addition to the close-up photos you provide. Otherwise, an excellent teardown article.

Jeff Smith - 返信

Thank you so much! This guide helped a lot. I would probably tear a ribbon cable and the casing if I didn't know there were hidden screws to remove the keyboard.
