Using Apple Hardware Test
If	you	suspect	a	problem	with	the	MacBook	hardware, 	you	can	use	the	Apple	Hardware	
Test	application	to	help	determine	if	there	is	a	problem	with	one	of	the	computer’s	
components, 	such	as	the	memory	or	processor. 	
To use Apple Hardware Test:
1  Disconnect	all	external	devices	from	your	computer	except	the	power	adapter. 		
If	you	have	an	Ethernet	cable	connected, 	disconnect	it.
2  Restart	your	MacBook, 	and	hold	down	the	D	key	as	it	starts	up.
3  When	the	Apple	Hardware	 Test	chooser	screen	appears, 	select	the	language	for		
your	location.
4  Press	the	Return	key	or	click	the	right	arrow	button.
5  When	the	Apple	Hardware	 Test	main	screen	appears	(after	about	45	seconds), 	follow	
the	onscreen	instructions.
6  If	Apple	Hardware	 Test	detects	a	problem, 	it	displays	an	error	code. 	Make	a	note	of	the	
error	code	before	pursuing	support	options. 	If	Apple	Hardware	Test	doesn’t	detect	a	
hardware	failure, 	the	problem	might	be	software	related.

Problems with Your Internet Connection
Your	MacBook	has	the	Setup	Assistant	application	to	help	walk	you	through	setting		
up	an	Internet	connection. 	Open	System	Preferences	and	click	Network. 	Click	the		
“Assist	me” 	button	to	open	Network	Setup	Assistant.
If	you	have	trouble	with	your	Internet	connection, 	you	can	try	the	steps	in	this	section	
starting	with	Network	Diagnostics.
To use Network Diagnostics:
1  Choose	Apple	()	>	System	Preferences.
2  Click	Network	and	then	click	 “Assist	me.”	
3  Click	Diagnostics	to	open	Network	Diagnostics.
4  Follow	the	onscreen	instructions.
If	Network	Diagnostics	can’t	resolve	the	problem, 	there	may	be	a	problem	with	the	
Internet	service	provider	(ISP)	you’re	trying	to	connect	to, 	with	an	external	device	you	
are	using	to	connect	to	your	ISP, 	or	with	the	server	you	are	trying	to	access. 	You	can	try	
the	following	steps.
Cable Modem, DSL, and LAN Internet Connections
Make	sure	all	modem	cables	are	firmly	plugged	in, 	including	the	modem	power	cord,	
the	cable	from	the	modem	to	the	computer, 	and	the	cable	from	the	modem	to	the		
wall	jack. 	Also	check	the	cables	and	power	supplies	for	Ethernet	hubs	and	routers. 	
Turn	off 	your	DSL	or	cable	modem	for	a	few	minutes, 	and	then	turn	it	back	on.	
Some	ISPs	recommend	that	you	unplug	the	modem’s	power	cord. 	If	your	modem	has	a	
reset	button, 	you	can	press	it	either	before	or	after	you	turn	the	power	off 	and	on.

Important:  Instructions	that	refer	to	modems	do	not	apply	to	LAN	users. 	LAN	users	
might 	have 	hubs, 	switches, 	routers, 	or 	connection 	pods 	that 	DSL 	and 	cable 	modem 	users	
do	not	have. 	LAN	users	should	contact	their	network	administrator	rather	than	an	ISP.
PPPoE Connections 
If	you’re	unable	to	connect	to	your	Internet	service	provider	using	PPPoE	(Point	to	Point	
Protocol	over	Ethernet), 	make	sure	you’ve	entered	the	correct	information	in	Network	
preferences. 	
To check PPPoE settings:
1  Choose	Apple	()	>	System	Preferences.
2  Click	Network. 	
3  Click	Add	(+)	at	the	bottom	of	the	network	connection	services	list, 	and	choose	PPPoE	
from	the	Interface	pop-up	menu. 	
4  Choose	an	interface	for	the	PPPoE	service	from	the	Ethernet	pop-up	menu. 	Choose	
Ethernet	if	you’re	connecting	to	a	wired	network, 	or	Wi-Fi	if	you’re	connecting	to	a	
wireless	network.
5  Click	Create.
6  Enter	the	information	you	received	from	your	service	provider, 	such	as	the	account	
name, 	password, 	and	PPPoE	service	name	(if	your	service	provider	requires	it). 	
7  Click	Apply	to	make	the	settings	active.

Network Connections
Make	sure	the	Ethernet	cable	is	plugged	into	your	MacBook	and	into	the	network. 	
Check	the	cables	and	power	supplies	to	your	Ethernet	hubs	and	routers.
If	you	have	two	or	more	computers	sharing	an	Internet	connection, 	be	sure	that	your	
network	is	set	up	properly. 	You	need	to	know	if	your	ISP	provides	only	one	IP	address	
or	if	it	provides	multiple	IP	addresses, 	one	for	each	computer.
If 	only 	one 	IP 	address 	is 	provided, 	then 	you 	must 	have 	a 	router 	capable 	of 	sharing	 	
the 	connection, 	also	known 	as	network 	address	translation 	(NAT )	or	“IP 	masquerading.” 	
	
For 	setup 	information, 	check 	the 	documentation 	provided 	with 	your 	router 	or 	ask	 	
the 	person 	who 	set 	up 	your 	network. 	You 	can 	use 	an 	AirPort 	base 	station 	to 	share	 	
one 	IP 	address 	among 	multiple 	computers. 	For 	information 	about 	using 	an 	AirPort	 	
base 	station, 	check 	Help 	Center 	or 	visit 	the 	Apple 	AirPort 	website 	at	 	
www.apple.com/support/airport.
If 	you 	can’t 	resolve 	the 	issue 	using 	these 	steps, 	contact 	your 	ISP 	or 	network 	administrator.
Problems with  Wi-Fi Communication
If you have trouble using  Wi-Fi communication:
	
ÂMake	sure	the	computer	or	network	you’re	trying	to	connect	to	is	running	and	has	a	
wireless	access	point.
	
ÂMake	sure	you’ve	properly	configured	the	software	according	to	the	instructions	that	
came	with	your	base	station	or	access	point.

Chapter 4      Problem, Meet Solution
	
ÂMake	sure	your	MacBook	is	within	antenna	range	of	the	other	computer	or	the	
network’s	access	point. 	Nearby	electronic	devices	or	metal	structures	can	interfere	
with	wireless	communication	and	reduce	this	range. 	Repositioning	or	rotating	the	
computer	might	improve	reception.
	
ÂCheck	the	 Wi-Fi	(Z)	status	icon	in	the	menu	bar. 	Up	to	four	bars	appear,	indicating	
signal	strength. 	If	the	signal	strength	is	weak, 	try	changing	your	location.
	
ÂGet	help	online	by	choosing	Help	>	Help	Center, 	and	then	searching	for	“wi-fi.”		
Also	see	the	instructions	that	came	with	the	wireless	device	for	more	information.
Keeping Your Software Up to Date
You	can	connect	your	MacBook	to	the	Internet	and	automatically	download	and	install	
the	latest	free	software	versions, 	drivers,	and	other	enhancements	from	Apple. 	
When	your	MacBook	is	connected	to	the	Internet, 	Software	Update	checks	to	see	if	
any	updates	are	available	for	your	computer. 	You	can	set	your	MacBook	to	check	for	
updates	periodically, 	and	then	you	can	download	and	install	updated	software.
To check for updated software:
1  Choose	Apple	()	>	System	Preferences.
2  Click	the	Software	Update	icon	and	follow	the	onscreen	instructions.
	
ÂFor	more	information, 	search	for	“Software	Update” 	in	Help	Center.

For	your	safety	and	that	of	your	equipment, 	follow	these	rules	for	handling	and	
cleaning	your	MacBook	and	for	working	more	comfortably. 	Keep	these	instructions	
handy	for	reference	by	you	and	others.
WARNING:  Incorrect	storage	or	use	of	your	computer	may	void	the	manufacturer’s	
warranty.
Important Safety Information
WARNING:  Failure	to	follow	these	safety	instructions	could	result	in	fire, 	electric	
shock, 	or	other	injury	or	damage.
Built-in battery		Do	not	remove	the	battery	from	your	MacBook. 	The	battery	should	
be	replaced	only	by	an	Apple	Authorized	Service	Provider. 	Discontinue	use	of	your	
MacBook	if	it	is	dropped	or	appears	crushed, 	bent,	deformed, 	or	damaged. 	Do	not	
expose	the	computer	to	temperatures	above	212°	F	or	100°	C. 	
Proper handling		Set	up	your	MacBook	on	a	stable	work	surface	that	allows	for	
adequate	air	circulation	under	and	around	the	computer. 	Do	not	operate	your	
MacBook	on	a	pillow	or	other	soft	material, 	as	the	material	can	block	the	airflow	vents. 	
Never	place	anything	over	the	keyboard	when	operating	your	MacBook. 	Never	push	
objects	into	the	ventilation	openings.
The	bottom	of	your	MacBook	may	become	very	warm	during	normal	use. 	If	your	
MacBook	is	on	your	lap	and	gets	uncomfortably	warm, 	remove	it	from	your	lap	and	
place	it	on	a	stable	work	surface.
