HELP!! afther I connected my TI-84 plus to my pc, it keeps saying: waiting... Please install operating system now. than it says ERROR! Press any key to turn unit off. then turn unit back on... I've tried...

You cannot get the calculator to behave as you describe just by connecting it to the computer. You must have done some other manipulations.
Try to find a classmate who has the same calculator (TI84 Plus or TI84 Plus Silver Edition) and effect a transfer of the OS from the classmate's calculator using an IO cable.

Ti-nspire with 84 keypad problems

It seems to me that you get the loading bar when you switch keypads. I just switched keypads, and when I reinserted the TI84 Plus keypad back again I found my last TI84 Plus screen contents still displayed.
As to the RAM cleared message, it probably is related to the batteries being depleted.
To verify battery charge level, you may use TI connect.

My TI84 plus silver edition calculator is giving me an incorrect sign whenever I do an exponential function. When I type in -25^2, it gives me -625 instead of 625. How do I fix this?

It's giving you the correct answer. It's calculating the negative of 25 squared. 25 squared is 625, and the negative of that is -625.

If you want to calculate the square of negative 25, you need to tell the calculator that.

Press ( (-) 2 5 ) ^ 2 ENTER .

How do I graph equations like x^2 + y^2 = 9 on my TI84 Plus silver calculator?

This is the equation of a circle centered on (0,0) and with radius r=3. You can draw it as a conic section.For that you will need the conics application. Look for it on
You can also draw it as two branches: y1=+ square root (9-x^2) and y2=-square root(9-x^2). The two parts may not overlap at the points on the the x-axis, but if you are willing to accept the calculator limitations you will have your graph.

I have installed the new operating system on my TI84 Silver Editions. It will not convert the square root of 5 to a fraction (thank goodness) but it does convert the square root of 720 to a fraction :( ...

The calculator is showing you its best fractional approximation to the number. To not have it do that, press MODE, up-arrow four times to get to the "ANSWERS:" line, use left/right arrow to highlight "AUTO" then press ENTER. Press 2ND [QUIT] to exit the mode screen.

Ti84 Plus Turns on, and turns off right away.

I had the same problem like yours. First, I reset the RAM and then it no longer turned off right away; but it responded extremely slowly. Second, I tried to install the new OS for it, but unsuccessful until I blowed really hard several times into the round connector. After that, the cursor started blinking. Finally, I downloaded the new OS into it and hoped that the problem never happen again.
You go to and follow their procedures to reset the RAM.

Ti84 plus, screen problem

  1. Press and release the gold [2nd] button. Verify that the blinking up arrow appears in the display.
  2. Press and hold the blue up or down arrow key to increase or decrease contrast, until the display is to your liking. Be alert: the display will change quickly.
The calculator will remember your contrast setting; you don’t have to adjust it every time you turn the calculator on.
