Hot Issues Forcing a Restart - 5
Forcing a Restart
If holding down the Command, Control, and Power keys fails
to restart the iMac computer after a system hang, you can
force a restart in one of two ways:
First, try inserting a straightened paper clip in the reset
button hole. (Open the I/O door on the side of the iMac. The
reset button hole is the top hole located between the Ethernet
and modem ports and marked with a triangle symbol.)
If the reset button method doesn’t work, try the following:
1. Unplug the power cord.
2. Wait at least 30 seconds and then reconnect the power
cord.
3. Restart the iMac by pressing the power button on either
the keyboard or the front of the computer.
