The TI-83 Plus is a robust graphing calculator that has been a staple for students and professionals alike for many years. Its longevity means that many people, whether inheriting one, finding an old one, or just getting started, might need a refresher on the basics. This guide will walk you through the surprisingly simple process of turning on your TI-83 Plus, troubleshoot common issues, and offer some maintenance tips.
Mastering Your TI-83 Plus: A Step-by-Step Power-Up Guide
Are you ready to unlock the computational power of your Texas Instruments TI-83 Plus? Whether you're gearing up for an algebra exam, diving into calculus, or just need to crunch some numbers, the very first step is to bring this marvel of engineering to life. Let's get started!

| How To Turn On A Texas Instruments Ti 83 Plus |
Step 1: Locate the Power Button – It's Easier Than You Think!
Before we dive into complex equations, let's find the most important button on your calculator.
Take a moment to look at your TI-83 Plus. You'll notice a array of keys, but one stands out for its primary function. The power button is almost universally located in the bottom-left corner of the keypad. It's usually a distinct color, often white or a light gray, and is clearly labeled with "ON."
Engage! Go ahead and press that "ON" button now. Did your screen light up? If so, congratulations! You're already halfway there. If not, don't worry, we've got some troubleshooting ahead.
Step 2: Observe the Screen – What Do You See?
Once you press the "ON" button, your calculator's screen will tell you a lot about its current state.
Upon successful power-up, you should see a blinking cursor in the top-left corner of the screen, or perhaps the last calculation you performed. This indicates that the calculator is ready to receive your commands.
What if the Screen is Blank or Dim?
If your screen remains blank, or if the display is very faint, this is a strong indicator of a power issue. This leads us to our next crucial step.
QuickTip: Copy useful snippets to a notes app.
Step 3: Address Power Sources – Batteries Are Key!
The TI-83 Plus runs on batteries, and like all electronic devices, it needs a good power supply to function correctly.
The TI-83 Plus uses two types of batteries: four AAA batteries for primary power and one CR1616 or CR1620 lithium coin cell battery for memory backup. While the AAA batteries power the calculator during use, the coin cell battery ensures that your stored programs, data, and settings are retained even when the AAA batteries are dead or removed.
Sub-Step 3.1: Checking the AAA Batteries
Locate the Battery Compartment: Turn your TI-83 Plus over. You'll see a large rectangular compartment on the back, usually held in place by a sliding cover or a small screw.
Open the Compartment: If it's a sliding cover, gently push it in the direction indicated by an arrow (usually downwards). If there's a screw, use a small Phillips-head screwdriver to loosen it (be careful not to lose it!).
Inspect the Batteries: Remove the old AAA batteries. Look for any signs of corrosion (a white, powdery substance). If you see corrosion, carefully clean it with a cotton swab dipped in vinegar or lemon juice, then dry thoroughly.
Insert New AAA Batteries: Always use fresh, high-quality alkaline AAA batteries. Pay close attention to the polarity markings (+ and -) inside the compartment and on the batteries themselves. Inserting them incorrectly will prevent the calculator from turning on and could potentially damage it.
Close the Compartment: Securely replace the battery cover.
Sub-Step 3.2: Checking the Memory Backup Battery
This battery is often overlooked but is crucial for data retention.
Locate the Small Circular Compartment: On the back of the calculator, usually near the top, you'll find a smaller, circular compartment. This houses the coin cell battery.
Open the Compartment: This usually requires a small flat-head screwdriver or a coin to twist open the cover.
Replace the Battery: Carefully pop out the old CR1616 or CR1620 battery. Note the orientation of the old battery before removing it (usually, the positive (+) side faces up). Insert a new, fresh coin cell battery with the correct orientation.
Close the Compartment: Securely replace the cover.
Step 4: Perform a Reset (If Necessary)
Sometimes, a simple power cycle isn't enough. A soft reset can clear minor glitches.
After replacing batteries, or if your calculator is behaving erratically, a soft reset can often resolve the issue.
Sub-Step 4.1: Soft Reset
Press and Hold: With the calculator on (or attempting to turn on), simultaneously press and hold the [2nd] key and the [DEL] key (which has "MEM" written above it in blue).
Release: Release both keys. You should see a message confirming the memory has been cleared. Be aware that this will clear any programs, variables, or settings you have stored on the calculator.

Sub-Step 4.2: Hard Reset (Use with Caution!)
A hard reset should only be performed as a last resort, as it will completely wipe all data and programs from your calculator.
Locate the Reset Button: On the back of the calculator, often near the memory backup battery compartment, there's a tiny, recessed button labeled "RESET."
Press the Button: Use a paperclip or a straightened staple to gently press this button. You'll feel a slight click.
Re-Check: Attempt to turn on your calculator after pressing the reset button.
Step 5: Adjust the Display Contrast
If your calculator turns on but the screen is still dim, the contrast might be set too low.
The TI-83 Plus has an adjustable contrast setting to accommodate different lighting conditions and battery levels.

Press [2nd] then [UP] or [DOWN]: To darken the display, press the [2nd] key followed by the [UP arrow] key. Each press will increase the contrast.
Lighten the Display: To lighten the display, press the [2nd] key followed by the [DOWN arrow] key.
Find the Optimal Setting: Continue adjusting until you find a comfortable and clear display.
Step 6: Consider Advanced Troubleshooting (If All Else Fails)
If you've followed all the steps above and your TI-83 Plus still won't turn on, or if it's exhibiting unusual behavior, it might be time for more advanced troubleshooting or professional help.
Corrosion in Battery Compartment: Even after cleaning, severe corrosion can damage the contacts, preventing proper power flow. In such cases, the contacts may need to be carefully scraped or replaced (which is usually a job for a professional).
Internal Damage: Dropping the calculator or exposing it to liquids can cause internal damage to the circuit board. This often manifests as a completely dead calculator or erratic behavior.
Faulty Keypad: While rare for the "ON" button specifically, a faulty keypad could prevent the calculator from registering the press.
Contacting Texas Instruments: If your calculator is still under warranty, or if you suspect a manufacturing defect, reaching out to Texas Instruments customer support is a good next step. They may offer repair services or replacement options.
Maintaining Your TI-83 Plus for Longevity
To ensure your TI-83 Plus continues to serve you well for years to come, consider these maintenance tips:
Store Properly: Keep your calculator in a protective case or sleeve when not in use to prevent scratches, drops, and dust accumulation.
Avoid Extreme Temperatures: Do not leave your calculator in direct sunlight, in a hot car, or in extremely cold environments, as this can damage the display and internal components.
Remove Batteries for Long Storage: If you plan on not using your calculator for an extended period (several months or more), it's a good idea to remove the AAA batteries to prevent leakage and corrosion. The memory backup battery can typically remain, though it will eventually drain over many years.
Clean Gently: Use a soft, dry cloth to clean the screen and keypad. Avoid harsh chemicals or abrasive materials.
Back Up Important Data: If you have valuable programs or data stored on your calculator, consider backing them up to a computer using a TI Connectivity Cable and software (if available for your specific model and operating system).
