The Computer Won’t Start
If your computer does not start when you turn on the power,
check the following:
1. Is the power light on? If not, remove any diskettes and turn
off the power. Make sure the power cord is securely
connected to both the AC inlet on the back panel and an
electrical outlet. Replace your main operating system
diskette, if necessary, and turn on the computer again.
