Possibility: Some third-Party programs (games essentially) are installed on the calculator. They may be ill-designed and circumvent/turn OFF the Power saving features of the calcuator.Also, Texas Instruments recommends to use alkaline (non-rechargeable) batteries only.

Why so long when i'm charging my lenovo a1-07 ideapad


Frequent Charging Shortens Battery Life Frequent charging shortens the life span of a Lithium ion battery. Batteries should be charged only after they expend all their power. b> Switching Batteries Switching batteries helps preserve battery life: If a cell phone or computer user puts in a spare battery while separately charging the primary Lithium ion battery, that helps extend the life of both batteries. b> Removing Batteries Most laptops charge the battery when a user plugs in the AC adapter. Users can adjust this setting by changing the power options. Windows places this option in the Control Panel, while the Gnome Linux desktop places power options under "Administrative Tools". Cell phones incorporate their own power-saving features that the user usually cannot control. b> When to Replace a Lithium Ion Battery If a laptop battery does not hold a charge for more than a few minutes, a user must replace the Lithium ion battery if he wants to use the computer without an AC adapter. Other Ways to Extend Battery Life Storing a battery in a cool, dry environment causes a lithium-ion battery to last a little longer and reduces the frequency of needed battery replacements. Hope this helps.

Batteries won't work


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Wont turn on


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.

My TI-84 calculator isn't working. When I press the "ON" button, sometimes it would respond, but most of the time it doesn't. The screen just remains blank. I've changed my batteries...


try taking out the triple A batteries and leaving the calculator to sit with them out for a minute or so, replace them and check if it's fixed. If that doesn't work you can do the same, but take out the small button back up battery as well. If you're still not having luck you should call ti cares (800-842-2737) they're usually helpful.

TI 82 Does it need the disk battery and 4 AAA batteries to work?


No. The calculator runs on the four AAA batteries. The lithium battery is solely to retain the contents of the memory while you change the AAA batteries. If you don't care about retaining the memory, you don't need the lithium battery. You do, however, need the AAA batteries to use the calculator.

My screen turns on but when you do anything it has random numbers, line and letters on it and i need to get it fixed immediatley


I've had this issue before with my TI-83 Plus. I'm not sure exactly the solution I used, but these steps progress through the mildest to most extreme methods of fixing the calculator.


Solution 1: Take the batteries out.

Odds are you've tried this already, but it bears mentioning.

With the calculator on, remove the triple A batteries housed in the back. After a few seconds, replace them and turn the calculator on.


Solution 2: Clear the RAM.

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.


Solution 3: Reinstall the operating system

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"

Here is the website to reinstall your OS. First you'll need the TI-Connect software.


Solution 4: Remove all sources of power. This is a risky move, but if your calculator will absolutely not work after you try even reinstalling the operating system, it might be your last hope.

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 put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...


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).

I have replaced the lithium battery and the triple a's still it will not work


Hello,
It is possible that the screen is too light to see anything. If that is the case you can try to darken the screen a bit to verify if it works.
To do so:
Press [2nd] key and release it.
Press and hold the UP arrow to darken the screen. Keep pressing until it is dark enough.

If that does not work, you may have to follow the link to the TI FAQ and Knowledge Base to an article that addesses the question of a graphing calculator not turning on.

Hope it helps.
