NoSleep 1.70 - No Sleep is a program that will keep Newton from going to sleep when Newton's AC adapter is powering it. No matter what sleep time you have set, Newton will remain alive. No Sleep Main Features - No Sleep is the only Newton keep-on-if-plugged-in program that does not alter Newton Internal things to function. No Sleep lets you have your own Power On and Power Off sounds. No Sleep can automatically change the Sleep Time when not on A/C for longer battery life. No Sleep displays the Data Backup Battery status. (That I know of and I think I've look at all of them.). Shareware.
