Small black square in top left...won't turn off

Upon turning on calculator, I only get a small black square in top left corner and nothing else. It won't turn off unless I remove a AAA battery. My 15 yr old son is in calculus and needs this thing! Please assist...thank you~

    I replaced all the batteries...the triple A's and the CR1616...still has the same problem. I think it's odd that I would have to spend between $67 and $87 to send this one back to Texas Instruments to get a refurbished one!

    My son noticed that one of the batteries leaked in his TI-84 and now it will only display a black square in the top left corner when turned on. The black square stays on for about 5 seconds and then turns off. Any suggestions? Thx

You should replace the AAA batteries with new ones, and should by a new set of back up batteries.

It won't finish the start up


It is looking for something to boot from. Remove any CD and USB drives. Then try physically reconnecting the drive. From there you will need to verify in BIOS.

Check first boot in BIOS as well.

Dc17 won't turn on


there is a reset button under the cover that houses the on/off switches. remove the handle/wand and look on the back (where the top of the hose sits) for 2 screws (its a torx/star head screw size t10 i believe). remove them and locate 4 small locking tabs that hold the switch cover to the frame of the vacuum. Depress them and pop the cover off (2 towards the top and 2 towards the bottom). Youll see 3 switches (2 square red buttons and one small cylindrical shaped one). Push the small red one (the one to the left if my memory serves me right). you should hear a click. if you do than the switch is reset. if not check all connections to all 3 switches. if you see nothing loose or not connected, you may need a new brushbar motor.

How do i use the radical symbol on my ti-30xs


The radical symbol is used to calculate square roots. It a radical has a small 3 to the top left of it, it means cubic root. It it has a a small n or a small x to the top left of it, it means nth root.

The way any of these roots works is one of the following:
Enter a number (positive for a square root or an nth root with n even) then press the square root button. The result is then displayed.

The other way is to press the root key then enter the number whose root you wan t calculate. The result is then displayed.

If you press the square root key and a radical is displayed withy a left parenthesis, you can be sure it is the second way.

How do I fix my calculator if I can turn it on but cannot turn it off and press any button after I turned it on?


do you have a solid black square in the top left corner?

if so, blow hard into the I/O port on the top of the calculator. That fixed the problem for me.

TI 84 plus calculator, flashing dot in upper left hand corner


Hello,

When you turn the calculator on, its screen is cleared, save for a small square on the top left corner. This is the cursor and it is blinking: The calculator is waiting for you to order it to perform some calculation.

Try this simple operation
[1] [+] [1] [ENTER]. The calculator will display the result one line down justified to the right.

Hope it helps.

No display on flip out screen


I have a Sony DCR-TRV30. Your camara is probably similar. On the bottom left outside corner of mine, there are two buttons, labeled "exposure" and "program AE," and a small thumb wheel above them. Set the indicator to "camera" and open the screen. Push the "exposure" button and a light grey rectangular screen with a minus sign on one end and a plus sign on the other will appear near the top left corner of the screen. Rotate the thumb wheel so that the small black square in the rectangular screen will move from the "+" side towards the "-" side while the image on the screen gets darker.
