Common Reset Procedures
When a reset procedure is required for troubleshooting, follow the applicable steps:
Resetting the System Management Controller (SMC)
To reset power management via the SMC chip:
1. Unplug all cables from computer, including power cord.
2. Wait at least 15 seconds. The SMC reset occurs automatically once the Mac mini has been
unplugged from AC power source for several seconds.
3. Plug power cord back in, making sure power button is not being pressed.
4. Reconnect keyboard and mouse to computer.
5. Press power button on back to start up computer.
Resetting the SMC means you will also need to reset the date and time (using the Date & Time
pane of System Preferences).
Resetting the Parameter RAM (PRAM)
To reset PRAM,
1. If the computer is on, turn it off.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to
hold these keys down simultaneously in Step 4.
Note: If the keyboard does not have an Option key, use the Alt key instead.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys.
Important: You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the
second time.
6. Release the keys.

Starting Up in Safe Mode
A Safe Boot is a special way to start Mac OS X when troubleshooting. To start up into Safe Mode
(Safe Boot),
1. Make sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, press and hold the Shift key.
Note: The Shift key should be held as soon as possible after the startup tone but not
before.
4. Release the Shift key when you see the screen with the gray Apple and progress indicator
(looks like a spinning gear). During startup, ”Safe Boot” appears on the Mac OS X startup
screen. To leave Safe Mode, restart the computer normally, without holding down any keys
during startup.

Quick Check
Noise/Hum/Vibration
• Buzzing noise
• Rattling noise
• Ticking noise
• Squeaking
1. Verify that the vents on the bottom and
back of the system are free of dust and other
obstructions that might inhibit proper airflow
through the system.
2. Launch Applications/Utilities/Activity Monitor.
Determine whether an application or process is
consuming a high percentage of CPU bandwidth.
CPU intensive applications can cause the fans
to run fast in order to maintain the proper
internal system temperatures. If needed, quit the
application or restart the system to resolve the
issue.
3. Eject optical media from optical drive. Out of
balance optical media can generate audible
noise. To resolve try a different brand of media.
For additional information jump to ‘ Optical Drive
Noisy’ symptom flow.Disconnect all third party
devices and confirm whether the odor is being
generated by the device.
4. Play sound sample at loud and soft volume
levels to determine if the noise is caused by the
speaker or the amplifier circuit. Jump to ‘Distorted

1. Start up the computer holding down the “D” key
on the keyboard to see if Apple Hardware Test on
the hard drive will boot. If so, run the diagnostic
or Apple Server Diagnostics. This will tell you the
hard drive is working.
2. Try starting the system to Apple Hardware Test
on the Install DVD or Apple Server Diagnostics. If
so, run the diagnostic. This will tell you that the
optical drive is working.
3. Start the computer holding down the Option
key on the keyboard. If the Startup Manager
is recognizing internal hard drive and optical
drive (if Install DVD is in the optical drive) and
any external bootable drives connected to the
system, SATA connections and external ports are
communicating with the logic board.
4. Remove SDRAM and install Known Good SDRAM
and start system. This will verify the SDRAM is not
the cause of a startup issue.
5. Using Disk Utility on Install DVD or external drive
to verify SMART status on the hard drive and
repair directory structure. This will tell you that
the optical drive is working, and will verify your
hard drive status and directory.
6. Boot from another computer of same type in
Target Disk Mode, or from an external FireWire
drive with compatible Mac OS. This will tell you
that your logic board is communicating properly
with a compatible Mac OS.
