Overview
2010-09-14
The MacBook Pro (13-inch) features a higher-capacity, longer-lasting embedded battery, a highspeed FireWire 800 port, and an SD card slot for removable ash media.
The higher capacity battery must be serviced only by an Apple Authorized Service
Provider. The customer must not attempt to remove or service this battery, and doing so may
void their warranty.
Refer to the following site for available congurations of the MacBook Pro (13-inch, Mid 2009)
and MacBook Pro (13-inch, Mid 2010): http://support.apple.com/specs/
MacBook Pro (13-inch) Basics — Overview 15
Safety: Battery Precautions
This computer contains an internal-only battery that is serviceable by Apple-authorized service
providers only. Tamper-proof screws are employed to prevent customers from attempting to
remove it.
WARNING: Every time you remove the bottom case, disconnect the battery cable from the
logic board.
WARNING: Because the battery is internal and connected to the logic board by a cable, it MUST
BE DISCONNECTED before performing service procedures. If you fail to do so, live current from
the battery will short circuit the components and render the logic board and/or LVDS cable
unusable.

Transferring the Serial Number
When replacing a bottom case, retain the customer’s bottom case until the repair is complete.
Before installing the replacement bottom case, use a ne tip permanent marker to write the
original serial number clearly and legibly in uppercase box letters directly onto the inside of the
new bottom case.
CAUTION: Take great care in deciphering the small typeface of the etched serial number
on the bottom case. You might need a magnifying glass to see it clearly. It is imperative
that you transfer the correct alphanumeric characters. Keep in mind that Apple serial
numbers always use the numbers 1 and 0 instead of the Roman letters “I” and “O.”

General Troubleshooting
Update System Software & Firmware
Important: Ensure the correct version Mac OS X and latest software and rmware updates have
been applied before you begin troubleshooting. Computers sometimes exhibit symptoms that
indicate the wrong Mac OS X system software is installed.
Firmware is the name given to software that is written into memory circuits such as ash
memory, that will hold the software code indenitely, even when power is removed from the
hardware. Firmware on Intel Mac computers is designed to be updated if necessary by running
the Mac OS X Software Update check (available in the Apple () menu) while computer is
connected to the Internet. For more information about rmware updates, refer to:
kBase # HT1557: About rmware updates for Intel-based Macs
Troubleshooting Theory
For general information on troubleshooting theory, go to GSX and nd the Service Training
course menu link. From there you can access the Troubleshooting Theory self-paced course.
Hardware vs. Software
For information on how to isolate a hardware issue from a software issue, refer to:
kBase #TS1388: Isolating issues in Mac OS X
For information on how to troubleshoot a software issue, refer to:
kBase #HT1199: Mac OS X: How to troubleshoot a software issue
kBase #TS1394: Mac OS X: Troubleshooting installation and software updates
kBase #HT2956: Troubleshooting Mac OS X installation from CD or DVD
Temperature Concerns
The normal operating temperature of this computer is well within national and international
safety standards. Nevertheless, customers may be concerned about generated heat. To prevent
an unneeded repair, you can compare a customer’s computer to a similar running model, if
available, at your repair site. For more information, refer to
kBase #HT1778: Apple Portables: Operating temperature

Liquid Contact Indicators
To help discover accidental damage to the computer, the top case includes spill sensors called
liquid contact indicators (LCI). The sensors are only visible when the bottom case and most of
the modules have been removed. Normally represented by small white dots, the LCIs turn red
when they have come in contact with liquid, such as an accidental spill.
MacBook Pro (13-inch, Mid 2010) has an extra LCI just below the trackpad set screw, which is not
present in the MacBook Pro (13-inch, Mid 2009).

Logic Board Power-On Pads, Mid 2009
Note: See following page for location of pads in Mid 2010 model.
On the logic board of the MacBook Pro (13-inch, Mid 2009), there are two pads that can
be shorted to power on the system. These pads are located above the trackpad ex cable
connector and below the hard drive ex cable connector. The power-on pads are shiny, silver,
square, and larger than the other (mostly round) silver pads nearby.
Important: Only short these two pads and no other pads, or you may damage the logic board.
The tip of a T8 or T10 screwdriver is about the right size to touch these two pads, without
touching other nearby components.

Common Reset Procedures
Resetting the System Management Controller (SMC)
The System Management Controller (SMC) is a chip on the logic board that controls all power
functions. If the computer is experiencing any power issue, such as not starting up, not
displaying video, sleep issues, or fan noise issues, resetting SMC may resolve it. To reset SMC:
1. If computer is on, turn it o by choosing Shut Down from the Apple () menu.
2. Connect power adapter to computer and to a working power source.
3. On built-in keyboard, press (left-side) Shift-Control-Option along with power button just
once. Important: Use Shift-Control-Option keys on left side of keyboard.
Note: When the LED on the MagSafe connector is orange/amber, resetting the SMC will
change it to green for a few seconds, indicating that SMC was correctly reset.
4. Wait 5 seconds and press power button to start computer. Note: If bottom case is removed,
you can alternately reset SMC by disconnecting both power adapter and main battery, and
holding down power button for 5 seconds.
For more information, refer to:
kBase #HT3964: Intel-based Macs: Resetting the System Management Controller (SMC)
Resetting Parameter RAM (PRAM)
PRAM stores certain system and device settings in a location that Mac OS X can access quickly.
Exactly which settings are stored in the computer’s PRAM varies depending on the type of
computer as well as the types of devices and drives connected. To reset PRAM:
1. If computer is on, turn it o by choosing Shut Down from Apple () menu.
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 keyboard does not have an Option key, use Alt key instead.
3. Press power button.
4. Immediately press and hold Command-Option-P-R keys.
Important: You must press this key combination before the gray screen appears.
5. Hold down keys until computer restarts, and you hear startup chime a second time.
6. Release keys.

Clamshell Service Diagnostic (CSD)
Clamshell Service Diagnostic (CSD) is a diagnostic tool that checks Apple’s latest portable
computers for the presence of AirPort, Bluetooth, LCD and Ambient Light Sensor (ALS) to assist
you in quickly making a failure determination.
Troubleshooting benets of using CSD include:
• Quick way (less than 1 minute) to determine whether clamshell-related modules (AirPort,
Bluetooth, LCD and ALS) are electrically connected without taking apart the system.
• Results of CSD can help pinpoint if any clamshell cables may need to be reseated to logic
board.
• Diagnostic results can help isolate a video or wireless issue to either clamshell or logic
board, to avoid unnecessary replacements of these components.
In the MacBook Pro (13-inch), CSD checks for the presence of the computer’s:
• AirPort
• Bluetooth
• LCD
• Ambient Light Sensor (ALS)
CSD does not check for the presence of the computer’s:
• iSight camera
• externally connected hardware components (such as USB or FireWire devices)
CSD does not check for issues with the OS X or other software-related problems such as
application or extension conicts.
