  4. Use a spudger to separate the top shell from the bottom one by prying the crease all around the calculator. The black part separates easiest
    • Use a spudger to separate the top shell from the bottom one by prying the crease all around the calculator.

      • The black part separates easiest

      • You do NOT need to worry about keeping one side face down. The buttons will not fall out

    • The middle part is very difficult to separate! You will need to use a lot of force.

      • You do NOT need to worry about tearing any cables.

  5. With the back shell off, you can now access the Reset button. Take off the white and black rubber to access the hard plastic part.
    • With the back shell off, you can now access the Reset button.

    • Take off the white and black rubber to access the hard plastic part.

      • These are two separate pieces.

  6. Gently bend back the Aluminum shield. You will not be able to take all of it off since it is partially glued on. There is some shielding wrapped around the LCD
    • Gently bend back the Aluminum shield. You will not be able to take all of it off since it is partially glued on.

      • There is some shielding wrapped around the LCD

    • If you need to access the LCD, you can pick it up and bend it back.

      • Be careful not to rip the tan ribbon cable. (Which is removable)

      • With the LCD out, you can now easily pop out the transparent, plastic cover that's connected to the shell. This allows you to replace the glue if it's weak.

  7. Here you can see all the components of the Motherboard. Unfortunately, all the components on the PCB (except the LCD ribbon cable) are all soldered onto the motherboard. Sadly, this is where the teardown ends. You can not access the buttons underneath the motherboard because it is heat-melted to the shell. You will need to break the melted bits to reach the buttons. :(

    • I thought I'd give this an unofficial repairability score. I give it a 6. The battery is trivial to replace. The shell is (mostly) easy to remove, the LCD screen, LCD plastic cover, and the Reset button can be replaced. However, you can not upgrade anything, nor easily replace the FLASH, ASIC, USB, LED, and battery contacts.
