The battery might go dead when you are in the middle of something.
Perhaps you have to change the battery. It is also possible that the calculator is damaged.
The TI 84 Plus graphing calculator takes 4 AAA batteries as well as a back up button cell battery to ensure that just because the batteries die does not mean the learning or storing has to.
"The TI-1766 had solar cells that eliminated the need for batteries and powered the calculator indoors and out." See http://www.thocp.net/hardware/ti_calculators.htm
Standard AA batteries work fine. Use 2 in series. Get the polarity right, positive pole nearest the center of the calculator, negative pole nearest the top. Put in a small piece of aluminum shim or foil on the plastic side to link them together. I've been doing this for 20 years and still use my 33E every day. One tough calculator.
Over time, you may notice that your battery doesn't hold a charge as long as it used to. This may be caused by frequent charges/drains or infrequent battery use. It is recommended that you "condition" your battery a few times a year to get the most out of it. To do this, simply charge your battery to the fullest and then disconnect the AC plug.
