Chapter 1: Operating the TI-84 Plus Silver Edition 5
• If Automatic Power Down™ (APD™) had previously turned off the graphing
calculator, the TI-84 Plus will return exactly as you left it, including the display, cursor,
and any error.
• If the TI-84 Plus is turned off and connected to another graphing calculator or
personal computer, any communication activity will “wake up” the TI-84 Plus.
To prolong the life of the batteries, APD turns off the TI-84 Plus automatically after about
five minutes without any activity.

The TI-84 Plus uses five batteries: four AAA alkaline batteries and one SR44SW or 303
silver oxide backup battery. The silver oxide battery provides auxiliary power to retain
memory while you replace the AAA batteries. To replace batteries without losing any
information stored in memory, follow the steps in Appendix C.
