My kid's calculator is not working; replaced new batteries including the lithium battery. yet, the calculator is not turning on.

Wrong battery, I am researching
1 Lithium Metal batteries required. (included)
https://www.amazon.ca/Texas-Instruments-TI-30Xa-Scientific-Calculator/dp/B00000JBNS

Duracel 76a is a standard alkaline battery according to this

https://www.amazon.ca/Duracell-Specialty-Alkaline-Battery-long-lasting/dp/B007IAWVUM

But No, LR44 is the same as 76a. Did you change both?? You said 'I replaced THE battery', there is clearly two batteries.

Time for a new one probably.

Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. You are having problems because you calculator won't turn on. I think you should try changing the batteries. Did you know that your calculator has two batteries powering it? Not only are the 4 AAA batteries powering it, but there is also a CR 3V Lithium Back Up battery powering it as well. First, try changing the 4 AAA batteries. If that still does not power your calculator properly, you will need to replace the lithium back up battery. You can find this at a department store or store that carries electronics. To do this, open your regular battery compartment. Above the AAA batteries is a compartment that says "BACK UP BATTERY CR1616 OR CR1620" with a picture of it. Use a small crosshead screwdriver to open the compartment. Take the old battery out and replace it with the new one. Rescrew the lithium battery compartment back on and close the AAA battery compartment. Turn on your calculator and see if that works. I hope this solution solves this.

The TI-30Xa uses two A-76 lithium batteries. Comparable battery model numbers include:

Duracell® D357
Eveready® 357
Maxell® LR44
Varta® V13GA

To replace the batteries:

• Remove slide cover. Place calculator face down.
• Using a small Phillips screwdriver, remove screws from back case.
• Remove back case.
• Remove discharged batteries.
• Install new batteries positive side up, as shown on diagram inside case.
• Run a coin across the reset pad on the upper right hand corner of the printed circuit board.
• Replace back case, and then replace screws.
• Press [OFF], [ON/C], [ON/C].

Note: The calculator cannot hold data in memory when batteries are removed or become discharged.

hi bckyshldn,

Did you remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. In the procedure that I give, you hold [DEL] and, re-insert 1 battery. I'm going to go ahead and, restate my instructions for a ti 83 Plus that won't turn on.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me anybody could make the same mistake. and of course the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.

1. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
   reinsert the AAA battery and then turn the calculator on. The calculator should display the
   message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator did not display the message try pressing and releasing the [2nd] key followed by pressing and releasing the up arrow for one second. goto step 2.
   
2. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
   "Waiting...Please install calculator software now". Follow the instructions for the
   TI-83 family or TI-84 Plus family to reinstall the calculator operating system. If the calculator did not turn on connect the calculator to the computer and open Ti Connect. Next, open Device Explorer. Is the calculator asking to be installed? goto step 3.
   
3. Steps to re-installing the operating system:
   

   ~Connect the TI Connectivity cable between the PC and the calculator.
   ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
   ~Follow the on-screen directions to reinstall the calculator's OS. When or, if the calculator install the fresh OS goto step 4.
   
   
   

4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
   
   
   

If the above process did not work. Try re-doing the procedure and, extend the time in step 4 by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

Now just in case this calculator wasn't posted correctly. Here's my instructions for a Ti 83 that won't turn on. This is not the same procedure that the Ti 83 Plus has.

1. Try a new set of AAA batteries.
   
2. Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.
   
3. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the
   AAA battery and then turn the calculator on.
   

4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. And of course if the calculator does not turn on, I re-do the procedure and, increase the amount of time by 5 minutes to ten minutes that all the batteries are removed.
   

The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

• Remove slide cover. Place calculator face down.
• Using a small Phillips screwdriver, remove screws from back case.
• Remove back case.
• Remove discharged batteries.
• Install new batteries positive side up, as shown on diagram inside case.
• Run a coin across the reset pad on the upper right hand corner of the printed circuit board.
• Replace back case, and then replace screws.
• Press [OFF], [ON/C], [ON/C].

The TI-30Xa uses two A-76 lithium batteries. Comparable battery model numbers include: Duracell® D357 and Eveready® 357

Remove all four AAA batteries. Press and hold down the ON key for at least ten seconds. Replace the batteries. Turn the calculator on.

The following are 4 different things you can try that is on the Texas Instruments Website: " 1. Try a new set of AAA batteries. 2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow. 3. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the AAA battery and then turn the calculator on. 4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. "

I've fixed my Voyage 200!! I fixed it using the 3rd solution listed below. I've placed them all in there in case the one I used din't work. The funny thing is the solutions listed weren't even for the Voyage 200. I mistakenly tried the wrong one, but it worked!! I've also posted some soultions listed for the Voyage 200 just incase the others don't work and the website I found these solutions can be found here. Good Luck!!

List of solutions that worked for me:

1. Try a new set of batteries (including the backup battery).
2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
3. Remove one of the AAA batteries. Press and hold the CLEAR key. While holding CLEAR, reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the CLEAR key and then press it one more time to remove the message. (worked for me!! Never actually said "Ram Cleared" just had a long box across the screen that filled up and POOF it was back!!)
4. Remove one of the AAA batteries. Press and hold the DEL key. While holding DEL, reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

Voyage Solutions:

For the TI-89 Family, TI-92 Family, and Voyage™ 200:

1. Try a new set of batteries (including the backup battery).
2. Adjust the contrast by pressing and releasing the Diamond Key key followed by pressing and releasing the [+] key; repeat as necessary. To adjust or lighten the display, use the [-] key.
3. Users of the TI-89 Titanium or Voyage 200 should see the following case before performing the following reset procedure to prevent the loss of valuable Apps.
   On the TI-92 family or Voyage 200, hold the [2nd] key and the [hand] key, then press and release the [on] key. On the TI-89 family, press and hold the [2nd] key, left arrow, and right arrow; then press and release the [on] key. This should reinitialize the operating system, in which you should see a progress bar filling on the screen.
4. Remove one of the AAA or AA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. TI-89, 92 Plus, or Voyage 200 users should see "Press I to install code...", and should press the [9] key. The calculator should then say, "Waiting to receive...". TI-89 Titanium users should see "Waiting to receive..." or "Waiting to received OS...". You will need to restore the calculator's operating system.

If one of these solutions doesnt work you will most likely need to purchase a new calculator.

Batteries:
Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!
