Problem: When I turn on the machine, nothing appears on the screen, but I hear two or more
beeps.

and you hear five beeps, have the computer serviced.
If you hear 4 cycles of 4 beeps each, the Security Chip has a problem. Have the
computer serviced.

Solution: Reinstall your operating system (see Chapter 4, Recovery options), and turn on the
computer. If you still see only the pointer on the screen, have the computer serviced.
