I upgraded from OS 9.1 to 9.2.1 to 9.2.2 in the process I lost both the energy saver and the sleep command. When I click sleep I get this message <Your computer can't sleep because some system software is missing.Reinstall software that came with you computer.>

My computer wouldn't accept the OS 9 disc so I reinstalled 9.2.1 followed by 9.2.2. Still can't sleep. How do I get the missing script ?
