    • Lift up the released battery by rotating it up and away from you.

    • Pull the battery out.

    • The battery is held in by a latch in the front of the battery socket and by tabs in the back. When putting the battery back in, line the tabs back up with the grooves located in the back of the socket and rotate the battery towards you. When in place, push the battery in until you hear a click.

    • Locate and unscrew the 7.5 mm screw on the CMOS cover.

    • Pull up the cover with your fingers.

    • Remove the cover.

    • You may have difficulty removing the cover, if so use a spudger to remove the cover.

    • The screw in the CMOS cover cannot be removed, it will remain with the CMOS cover. The screw is used to tighten and loosen the cover.

    • Use a Phillips #0 screwdriver to remove the 14.5 mm screw that is located inside the CMOS socket.

    • This screw is labeled with a small picture of a keyboard adjacent to the screw.

    • If the lock switch is operational, slide the lock switch up vertically to release the optical drive.

    • This step is for removing the whole optical drive and not the optical drive control panel. Both steps will lead to unscrewing the optical drive screws.

    • Remove the optical drive after it is released.

    • Step 10 will go over the steps to take if your lock switch is not operational. Skip step 10 if you were able to eject the optical drive with the operational optical drive lock switch.

    • This step is used only if your optical drive lock switch is not operational or broken.

    • Locate the optical drive on the bottom left wall of the laptop.

    • Remove the optical drive control panel with a thin flat tool

    • If your optical drive lock switch is operational, then use the lock switch instead to eject and remove the whole optical drive as explained in step 5. It is easier to use the lock switch to remove the whole optical drive.

    • Turn the laptop over and open the laptop.

    • Do not pull the frame all the way up because there are two flat cables located beneath the frame that could tear if pulled too hard.

    • Gently lift up the frame surrounding the keyboard without pulling off the keyboard.

    • Use a plastic opening tool or opening picks to lift the frame. Metal tools should be used as a last resort, as they may cause further damage to the device.

    • Disconnect the 2 ribbon cables attached to the surrounding keyboard frame.

    • Do not pull up the keyboard with the surrounding keyboard frame.

    • Underneath the keyboard there is a flat cable that connects the keyboard to the computer. Do not remove the whole keyboard just yet because there is a cable that has to be detached first. If the keyboard is pulled too hard, the cable may rip.

    • Gently lift up the key board from the side closest to you, flipping the keyboard away from you. Do not remove the whole keyboard just yet because there is a cable that has to be

    • Locate the two grey tabs on the right and left sides of the ribbon cable.

    • Push both grey tabs up towards the back side of the laptop with your fingers or a plastic spudger.

    • The metal spudger is great when you need serious prying power, but it is not ESD safe, and may cause further damage to your device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.

    • When the two gray tabs are pulled up, you are ready to go on to the next step.

    • Gently pull the flat cable out of the retaining flap with your hands.

    • The flat cable is very weak so be careful when handling it.

    • Remove the keyboard from the laptop.

    • When replacing the keyboard frame, make sure to reattach the 2 ribbon cables and then insert the bottom keyboard tabs into the grooves.

    • Insert the keyboard after the keyboard frame is in place by attaching the tabs into the grooves and pushing the keyboard into place.

On Step 13, there is a screw connecting the frame near where your left hand is gripping the frame that was not mentioned. You have to lift the keyboard a bit to access it.

Edit to my earlier comment: On Step 13, there are two screws connecting the frame near where your left hand is gripping the frame that were not mentioned, one similar in size to the two that were removed after the optical drive in step 11 and one similar to the four removed in step 6. You have to lift the keyboard a bit to access them.
