MacBook Pro Firmware Updates
Firmware is the name given to software that is written into memory circuits such as flash 
memory, that will hold the software code indefinitely, even when power is removed from the 
hardware. Firmware on Intel Mac computers is designed to be updated if necessary through a 
software update.
EFI and SMC firmware is stored on the MacBook Pro’s logic board. EFI firmware updates update 
the Boot ROM, and SMC Updates update the System Management Controller firmware. The SMC 
manages fans and other environmental parameters that are independent of the Boot ROM.
Firmware symptoms can be easily mistaken for hardware issues (e.g. overheating issues, fan noise 
issues, etc.). Always check both EFI and SMC firmware versions and update if necessary before 
replacing any hardware components in the MacBook Pro.
The following lists describe the type of symptoms that may be resolved by updating the EFI and 
SMC firmware in the MacBook Pro.
Symptoms that may be resolved by updating EFI firmware:L1 Cache reporting as bad
• 
Boot Camp not booting into Windows
• 
Built-in FireWire has GUID zero if ExpressCard FireWire is present at boot
• 
Auto-reboot after wake from sleep
• 
Stuck in Target Disk Mode upon restart
• 
Cannot eject media (various conditions)
• 
Bad media taking too long to eject (including holding mouse button down at startup taking 
• 
minutes to eject)
Auto-reboot after wake from sleep
• 
Symptoms that may be resolved by updating SMC firmware:
Status LEDS on battery do not light until the pack has charged for approximately 10 minutes
• 
Unusual fan behavior and thermal management issues
• 
Please follow the steps outlined in Knowledge Base article 303364 About firmware updates for 
Intel-based Macs to perform an EFI and/or SMC firmware update. 
Information about firmware versions for Intel Macs can be found in Knowledge Base article 
303880 Mac OS X: Firmware Updates for Intel-based Macs.

Software Troubleshooting Tips and Tools
All MacBook Pros require an Intel-compatible Mac OS.
For the MacBook Pro (17-inch), use Mac OS X 10.4.6 or later only.
• 
For the MacBook Pro (17-inch Core 2 Duo), use Mac OS X 10.4.8 or later only.
• 
For the MacBook Pro (17-inch 2.4GHz), use Mac OS X 10.4.9 or later only.
• 
For the MacBook Pro (17-inch Early 2008), use Mac OS X 10.5.2 or later only.
• 
Login window and account
Mac OS X requires at least one user account to be established—the Administrator’s account. 
By default, the Accounts system preference pane has the “Log in automatically [Admin’s name]” 
checked. This automatic login setting allows the system to boot into the Finder without having a 
login prompt. However, if this box is not checked, you need a password to get to the Finder, and 
you need to create a user account after you reinstall system software.
Customer forgot password
If the customer forgot the password for the computer:
Insert the MacBook Pro Mac OS X Install Disc 1 DVD.
1.  
Restart the computer while holding down the C key on the keyboard.
2.  
When the installer appears, chose Reset Password under the Installer Utilities menu
3. 
Follow the on-screen instructions.
4.  
Safe Mode
Safe Boot is a special diagnostic way to start Mac OS X when troubleshooting. Safe Mode is the 
state Mac OS X is in after a Safe Boot. Starting up in Safe Mode does five things to simplify the 
startup process and operation of the computer:
It forces a directory check of the startup (boot) volume. It is identical to using Disk Utility’s 
• 
Repair Disc or the fsck –fy terminal command.
It loads only required kernel extensions (some of the items in /System/Library/Extensions).
• 
It disables all fonts other than those in /System/Library/Fonts
• 
It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/, 
• 
where (uid) is a user ID number such as 501.
It disables all startup items and any Login Items.
• 
To start up into Safe Mode (to Safe Boot), do this:
Be sure the computer is shut down.
1.  
Press the power button.
2.

Immediately after you hear the startup tone, press and hold the Shift key.
3. 
Note: The Shift key should be held as soon as possible after the startup tone but not before.
Release the Shift key when you see the screen with the gray Apple and progress indicator 
4.  
(looks like a spinning gear). After startup, the words “Safe Boot” appear in red letters under 
the Apple logo on the Mac OS X login screen. 
Note: The Safe Boot startup process takes longer than a normal startup. It can be quite long 
(several minutes) depending on the amount of time it takes to check and repair the directory 
(if needed).
To exit Safe Mode, restart the computer normally, without holding down any keys during 
5. 
startup.

How to Use the Symptom Charts
The Symptom Charts included in this chapter will help you diagnose specific symptoms related 
to the product. 
The steps to solve a symptom are listed sequentially. You might not need to perform every 
step before the symptom is resolved. Start with the first step, and then test for the symptom. If 
the symptom persists, replace any modules you removed, go to the next step, and test again. 
Continue down the list until the symptom is resolved. 
Startup
Startup Sequence
The Intel-based MacBook Pro starts up very much like the previous professional Macintosh 
notebook computers. If power is available to the system from the battery and/or AC power 
adapter, pushing the power button will boot the system and begin the boot process.The screen will stay dark. The sleep LED will glow solid. This will last a few seconds.
• 
As the system boots, a power-on self test (POST ) will be performed. See 
•  POST	Error	Codes 
listed later for failure results.
If the system is not muted, you will hear a boot beep. The backlight will turn on and the 
• 
sleep LED will turn off. 
The screen will turn gray. The Apple logo will appear and then the turning gear will appear.
• 
The desktop pattern will show up, as well as the menu bar start populating.
• 
No Power, No Video
The computer will not power on (no sleep light, no fan movement, no hard drive spin-up,  
no Caps Lock LED illumination when pressed, and no display illumination).
Note: After each step, check that the system is not supplying power to the logic board. If you see 
the sleep LED come on or the Caps Lock LED illuminate when the key is pressed, then the system 
is indeed drawing power. In this case, hold down the power button for six seconds to insure the 
system is shut down before working on the machine. At this point, the issue is no longer a ‘No 
Power, No Video’ problem. Move on to the Power, but No Video troubleshooting section.
Note: Examine the display carefully. An image may be barely present on the screen, but with no 
backlight clearly illuminating the image. In this case, the system is working properly except for 
the backlight. Use the Display: 	Dim	Video troubleshooting section to resolve this issue.

Note: With the MacBook Pro (17-inch 2.4GHz and Early 2008), unlike previous models, if you 
use the MacBook Apple 60W Portable Power Adapter to power the system, the battery will 
need a minimum charge to be able to boot the system. If the battery is fully depleted and no 
85W adapter is available, allow the battery to charge first before turning on the system. 
Reset the SMC (power manager) as described in “
5.  Resetting the System Management 
Controller (SMC)”  under “Troubleshooting Tips and Tricks” in the previous section.

Power-On Self Test (POST) Error Codes
The computer automatically performs a power-on self test when it is turned on after being fully 
shut down (not a restart). This section describes what to do if you hear beeps during startup. 
When this occurs, the sleep LED will stay on, occasionally flashing.
MacBook Pro relies on a combination of tones and blinking sleep LEDs to display power-on self 
test (POST ) error codes.
If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory—also 
referred to as RAM), or the RAM installed does not meet the appropriate specifications, the screen 
will remain black but the power LED on the front of the computer will blink once per second to 
signal the error. This error condition may be due to physically damaged RAM, the incorrect type 
of RAM, or not having any RAM installed.
Some RAM may appear to pass the power-on self test (POST ) but still cannot be addressed by 
the operating system. In this case, the computer will display a gray screen, sound three tones and 
blink the power LED on the front of the computer three times, pause, and repeat the blinking 
until the computer is turned off.
