It has a solar battery. It has to be in the light, either sun light or artificial light to operate. HOWEVER, if the battery is shot, it must be replaced. Take your calculator to any radio shack store and ask them to test the battery for you. If it is no good, they will be able to replace it for a fee.

Hit the "2nd" button in the upper left hand corner of the keypad, and then the "+" button (lower right hand corner). Then either click the down arrow once and then "enter" or just hit the "2" button. (the selection should say "2: Mem Mgmt/Del...") Hit Enter again (selecting the "1: All..." selection) Scroll through the programs on her calculator and either hit the "Del" button (upper right hand corner of the keypad) to delete the programs/variables, or hit "ENTER" to archive them. The archived programs have an asterisk, " * ", in front of them. (Note: Once you delete the programs, you CAN NOT get them back) If you have variables on there "L1" "A" etc. you can delete them and use them again later, obviously.

You can bypass this whole thing and just do "2nd" "+" "7". This combination will reset the calculator and delete any programs that are unimportant to the calculator. You will be left with the "Finance..." option in the APPS menu only...nothing else. You should be able to clear up the problem either way.
