Replacing the Internal Backup Battery
Your	Mac	Pro	uses	a	BR	2032	lithium	coin	cell	battery	that	preserves	settings, 	such	as	
the	date	and	time, 	when	your	Mac	Pro	is	off. 	If	you	notice	intermittent	problems	when	
your	Mac	Pro	starts	up, 	or	changes	in	the	date	and	time	settings, 	replace	the	battery.
Important:  Dispose	of	the	old	battery	according	to	your	local	environmental	laws.
To	replace	the	battery:
1  Open	your	Mac	Pro	and	remove	the	side	panel, 	following	the	instructions	in	“Opening	
Your	Mac	Pro” 	on	page	33.
2  Remove	any	PCI	Express	cards	that	block	access	to	the	battery. 	See	“Adding	PCI	Express	
Cards” 	on	page	68	for	instructions.
3  Remove	the	old	battery	from	the	holder.
WARNING:  Installing	the 	battery 	incorrectly 	may 	cause 	an 	explosion. 	Use 	only 	the 	same	
type 	of 	battery 	or 	an 	equivalent 	recommended 	by 	the 	manufacturer 	of 	the 	original.

page	68).
6  Replace	the	side	panel	and	push	the	latch	down	to	secure	it.

Occasionally	you	may	have	problems	while	working	with	your	Mac	Pro. 	Read	on	
for	troubleshooting	tips	to	try	when	you	have	a	problem. 	You	can	also	find	more	
troubleshooting	information	in	Help	Center	or	on	the	Mac	Pro	Support	website	at	
www.apple.com/support/macpro.
When	you	experience	a	problem	with	your	Mac	Pro, 	there’s	usually	a	simple	and	quick	
solution. 	Think	about	the	conditions	that	led	up	to	the	problem. 	Making	a	note	of	
things	you	did	before	the	problem	occurred	will	help	you	narrow	down	the	possible	
causes	of	the	problem	and	find	the	answers	you	need. 	Things	to	note	include:
	
ÂAny	software	that	you	recently	installed.
	
ÂAny	new	hardware	(such	as	memory, 	graphics	or	PCI	Express	cards,	hard	disk	drives)	
that	you	installed	or	peripherals	that	you	connected.
An Ounce of Prevention
If	you	have	a	problem	with	your	computer	or	software, 	having	kept	up-to-date		
Time	Machine	backups	ensures	that	your	data	won’t	be	lost. 	If	you	make	regular		
Time	Machine	backups, 	you	can	restore	your	software	and	all	your	data	to	exactly		
the	way	it	was	at	the	time	of	the	backup. 	Even	serious	issues	are	of	less	concern		
when	you	safeguard	your	information	with	 Time	Machine.
For	important	information	about	backing	up	your	server	data, 	see	the	Lion	Server

Problems with Your Mac Pro
If	your	Mac	Pro	doesn’t	respond	or	turn	on, 	if	you	have	trouble	ejecting	a	disk,	or	if	the	
status	light	is	flashing, 	try	the	steps	in	this	section.
If the computer doesn’t respond or the pointer doesn’t move
	
ÂMake	sure	the	keyboard	is	connected	by	unplugging	and	then	plugging	in	the	
connector, 	and	make	sure	it	is	firmly	seated. 	
	
ÂPress	the	Command	key	(x)	and	Q	key	at	the	same	time	to	try	to	quit	the	
current	application.
	
ÂPress	the	Command	key	(x)	and	period	key	at	the	same	time. 	If	a	dialog	appears,	
click	Cancel.
	
ÂChoose	Apple	()	>	Force	Quit	and	select	the	application	you	want	to	quit. 	You	can	
also	force	quit	by	pressing	the	Esc, 	Option,	and	Command	(x)	keys	at	the	same	time. 	
Restart	your	Mac	Pro	by	choosing	Apple	()	>	Restart	to	be	sure	the	problem	is	
entirely	cleared	up. 	You	can	also	restart	by	pressing	the	power	button	(®)	for	about	
5	or	6	seconds	until	your	Mac	Pro	shuts	down. 	Press	the	power	button	(®)	again	to	
start	up	your	Mac	Pro.
	
ÂIf the problem occurs only when you use a particular program, 	check	with	the	program’s	
manufacturer	to	see	if	it	is	compatible	with	your	computer.
	
ÂIf the problem occurs frequently, 	choose	Help	>	Help	Center	and	search	for	 “problems.“
If the computer doesn’t turn on or start up
	
ÂMake	sure	the	power	cord	is	connected	to	a	working	power	source. 	The	plug	on	
the	power	cord	must	be	completely	inserted	into	the	computer’s	power	socket	and	
firmly	seated. 
						

							78Chapter 4      Problem, Meet Solution
	
ÂRestart	your	computer	while	holding	down	the	Command	key	(x)	and	R	key, 	until	
the	computer	restarts. 	When	the	Mac	OS	X	Utilities	application	appears, 	select	an	
option	to	repair	your	disk, 	restore	your	software,	or	reinstall	Mac	OS	X	and	Apple	
applications	from	the	Mac	OS	X	Utilities	pane. 	For	more	information,	see	“Repairing, 	
Restoring, 	or	Reinstalling	Mac	OS	X	Software” 	on	page	80.
	
ÂIf	your	computer	still	does	not	start	up, 	try	resetting	the	parameter	random	access	
memory 	(PRAM). 	Turn 	on 	the 	computer 	and 	immediately 	hold 	down 	the 	Command 	( x ),	
Option, 	P, 	and 	R 	keys 	until 	you 	hear 	the 	startup 	sound 	a 	second 	time. 	Release 	the 	keys. 	
The	PRAM	is	reset	to	the	default	values	and	your	clock	settings	may	need	to	be	reset.
• If	your	computer	does	not	start	up	after	resetting	the	PRAM, 	restart	your	computer	
while	holding	down	the	Option	key	to	select	your	startup	disk.
• If	this	doesn’t	work, 	restart	your	computer	while	holding	down	the	Shift	key.
If you’re unable to eject a disc
A	file	on	the	disc	may	be	in	use. 	Quit	applications	that	are	open, 	and	then	try	again.
If	that	doesn’t	work, 	choose	Apple	()	>	Restart	and	hold	down	either	the	mouse	
button	or	the	Media	Eject	key	(C)	on	an	Apple	Keyboard.
If	that	doesn’t	work:
1  Shut	down	the	computer	and	remove	the	side	panel	(see	the	instructions	on	page	33).
2  Pull	the	optical	drive	carrier	out	of	the	optical	drive	bay	(see	 “Replacing	an	Optical	
Drive” 	on	page	62).
3  Carefully	insert	the	end	of	a	straightened	paper	clip	into	the	small	hole	on	the	front	of	
the	optical	drive.

4 Push	firmly	until	the	tray	opens, 	remove	the	disc,	and	push	the	tray	to	close	it.
5  Put	the	optical	drive	carrier	and	the	side	panel	back	in	place	(see	 “Replacing	an	Optical	
Drive” 	on	page	62).
If the status light flashes and the computer doesn’t start up
	
ÂIf	you	recently	installed	memory, 	a	PCI	expansion	card,	or	another	internal	
component, 	make	sure	that	it	is	correctly	installed	and	that	it	is	compatible	with	your	
computer. 	See	if	removing	it	allows	the	computer	to	start	up.
	
ÂIf 	the 	status 	light 	still 	flashes, 	determine 	the 	number 	of 	flashes 	to 	identify 	the 	problem:
• One short flash followed by a longer off period:  	No	valid	memory.
• Three short flashes followed by a longer off period:		Failed	memory.
Problems with Software
When	an	application	freezes	or	doesn’t	respond, 	Mac	OS	X	provides	a	way	to	quit	the	
application	without	restarting	your	computer. 	
To force an application to quit:
1  Press	Command	(x)-Option-Esc	or	choose	Apple	()	>	Force	Quit	from	the	menu	bar.
2  Select 	the 	name 	of 	the 	application 	you 	want 	to 	quit 	in 	the 	Force 	Quit 	Applications 	dialog.
3  Click	Force	Quit.
The	application	quits, 	leaving	all	other	applications	open.

Repairing, Restoring, or Reinstalling Mac OS X Software
If	you	have	a	problem	with	your	Mac	software	or	hardware, 	Mac	OS	X	provides	repair	
and	restore	utilities	that	may	eliminate	problems	and	can	even	restore	your	software	
to	its	original	factory	settings. 	You	can	access	these	utilities	from	the	Mac	OS	X	Utilities	
application, 	even	if	your	computer	isn’t	starting	up	correctly.
