Re: calc stops working

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem.

Ti-83 plus silver edition. calc won't turn on.

Well, if screen shows the RAM CLEARED message, that means your calculator is working. Just press the [CLEAR] key, message will be erased and you are ready to crunch numbers.

Hope it helps.

Ti 84 not working

Since it gets tossed around a lot, it is possible though improbable that the batteries lose contacts with the electrical terminals.
You may try to darken the screen a bit.
1. Press [2nd] key and release it
2. Press [UpArrow] and release it.
3. Repeat steps 1 and 2 in sequence until contrast is satisfactory.

If that does not fix the problem, use a calc-to-calc cable and try sending something to it from a working calculator.

You can also download the TIConnect software from and install it on your computer. Then connect the calculator to the computer by means of a USB cable, a TISilverCable, or a TI Graphlink (Black cable). Turn the calculator ON, run TIConnect, connect calc-to-computer and Click TIDEVICEINFO in TIconnect main window.

If it tells you NOT FOUND, on any of the ports, click the communication settings: Set the device type to you calculator model. Set the cable type. Set the port (COM x) or USB1
If calculator is not detected through any of the available ports (COM ports, or USB), then it would suggest that calculator is in need of repairs.

Hope it helps.

Reloading OS

Apparently you can reset the calc if you remove a battery, hold delete and re-insert the battery....

However, try this...Find somebody with the same calc and connect them together. On the working calc Press 2nd, link [x,t,n], G: send OS and wait for good things to happen...

First time used in months

Check the batteries polarity.
Perhaps it needs a "reset", some calcs do have a "button" therefor, some do if you press the start button for some seconds.
Try to leave the calc overnight without any batt. inside.

None of my buttons work except the ON button

Sounds like a possible short to me, But I don't have experience with that cause I have yet to test my calc with water if you know what I mean... The one thing that I can suggest is trying to connect with another persons calc and try the "send OS" command to see if that will reset your calc to a working state. Sorry to hear about the damage though.

Standard deviation

Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.
