My HP 48GX recently have ((.)) in the display. I thought that is the indicator of low battery. However, I replace battery new several times the same display still appears. Even after turn off...


Somehow an alarm got set. Execute the command ACK once and see whether the indicator goes away.

To enter the command, press and hold the ALPHA key, then press and release the A, C, and K keys in turn, then release ALPHA, and press ENTER. But you already knew that, didn't you?

My Ti 89 won't turn on an I put brand new batteries in


TI calculators have a habit of dimming the screen contrast 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 hold the diamond key and press the the + key to darken the screen. If you go too far, use the diamond and - keys to lighten the screen.

If this doesn't do it, please reply to this post and we can try more drastic measures, though they may cause the loss of memory.

TI-84 Plus Silver Edition, purchased brand new 7 months ago. Today it quit working, replaced the AAA batteries(brand new) and can't get the unit to turn back on.


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.

If this doesn't do it, please reply to this post and we can reset the calculator, though that will wipe out the contents of memory.

My TI-89 Titanium won't turn on!


A hard reset will clear all memory and should give you back control of the calculator.

1. Put the batteries in the calculator.

2. Press and hold left arrow, right arrow, and 2nd keys.

3. Press and release ON.

My TI-83 Plus Calculator will not turn on


This is from TI FAQS:

Solution 11900: Troubleshooting a TI Graphing Calculator That Will Not Turn On.

For the TI-83 Plus Family, TI-84 Plus Family:
Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect™ first.
  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 [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.
  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.

A couple of days a go my when i turned my calculator on all these lines would appear. i pressed clear and they would go away. I thought it was a battery problem so i switched the batteries and now when i...


You may need to adjust your contrast. After turning the calculator on, press the 2nd button and then hold down the down arrow. This will lighten the screen if the contrast is the problem.

If this doesn't work, you might try resetting your calculator. Take out the backup battery that is located behind a little door with a screw right above the 4 AAA batteries. Leave all batteries out for about 8 hours and then reassemble. Hopefully when you turn it on, this will work. Good luck

TI-83 Plus Problem


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!
