If your Casio Electronic Keyboard won't power on, there are a few things you can check: * Ensure the AC adapter is properly connected or that the batteries are correctly installed. * Try replacing the batteries with a fresh set or use the AC adapter. * If a 'Please Wait' message appeared during an operation, and the keyboard still won't turn on, you can try a reset: Hold down the R-2 ([B] E.Piano) and R-5 ([E] BASS) buttons while pressing the L-1 (POWER) button. Be aware that this will erase all data and restore factory settings.
