I have three TI-84 PLUS Silver Edition graphing calculators that will not work. Can you help me?

    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.

    Does this do any good?

Having gone over a month without a response to my query, I assume my suggested screen adjustment solved the problem.

Hello,
To enter the inequation you split it into two inequalities

Graph is as follows

Use [2nd][CATALOG] to access the relaional operators less than or equal, greater than or equal, and the operator AND.
To access the inequality signs scroll upwards from abs( to reach the bottom of the catalog.
Note: You can use t as variable only in parametric graphs. Use x.
Hope it helps.

Ti-84 plus silver edition will not graph


try going into the memory men (2ND - +), and selecting option 2.  Delete some stuff you know you don't need.  If the problem persists, 2ND - +, this time option 7.  Reset the defaults.  You won't lose anything, it will just reset the settings that may be causing this issue.
