Ti-84 Basic Disassembly

How to disassemble your Ti-84 or Ti-84 silver.

Tools needed:
1) Torex #7 (t-7) screw driver
2) Small Phillips screw driver

Remove main battery cover and take out batteries.

Remove the back up battery cover, this will require a Phillips screw driver. After cover has been remove *take out the back up battery.*

** WARNING**
Taking out the backup battery will clear your system RAM, which means that all of your saved programs will be gone.

Use your Torx screw driver to remove the 6 screws noted below.

After removing all 4 screws take a flathead screw driver or a knife and gently pry the 2 halves of the cover apart at each corner. You will hear it pop a few times, after prying a little cover should come off with ease.

Now that you have removed the rear cover you should see a foil backing over the main circuit board, to remove this you will have to first remove the 2 screws marked below.

Now you need to remove the other 4 circuit board screws.
After removing the last 4 screws the circuit board should be loose, lift up on it carefully to avoid flinging keys everywhere (sometimes the keypad will stick to the circuit board).

If your keypad didn't come out when you took the circuit board out it will look like this. Just take you keypad out and your Ti-84 is completely dissembled.

Now your ti-84 is completely dissembled. Do with it as you please, in my case my keys were sticky so I used some isopropyl alcohol to clean them off.
