@SwiftOnSecurity To quote the #AppleNewton #FAQ:
"For the MessagePad 2000 and MessagePad 2100 only, remove the battery, cards, and power adapter. Let the Newton sit by itself for a few hours. Leave it a whole day or a whole night if you can. You won’t lose any data. Then put in fresh alkaline batteries, and plug in the power adapter. Press the reset button. This procedure cures nearly every turning-on problem these models have."
