							MacBook Pro (17-inch, Mid 2010) General Troubleshooting — Liquid Contact Indicators 21 2010-06-11
Liquid Contact Indicators
Liquid contact indicators (LCI) have been added to specific locations on current Mac portables 
to help determine if systems have been damaged by liquid. The sensors are only visible when 
the bottom case and some 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.
For more information, refer to Knowledge Base article HT3400:  “About Liquid contact indicators 
(LCI) on portable computers.” http://support.apple.com/kb/HT3400
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. If the computer is on, turn it off by choosing Shutdown from the Apple () menu. 
2.  Connect the power adapter to the computer and to a working power source. 
3. Important: Use the keys on the left side of the keyboard. On the built-in keyboard, press 
Shift-Control-Option along with the power button once. 
Note: When the LED on the MagSafe connector is orange, resetting the SMC will change it 
to green for a few seconds, indicating that SMC was correctly reset. 
4.  Wait 5 seconds and press the power button to restart the computer.  Note: If bottom case 
is removed, you may alternately reset the SMC by disconnecting the power adapter and the 
main battery, and holding the power button down for five seconds.

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.

							MacBook Pro (17-inch, Mid 2010) General Troubleshooting — Display Issue: Pixel Anomalies 23 2010-06-11
Display Issue: Pixel Anomalies
When displaying a single color over the screen area, the LCD panel might show one or more 
pixels that are not properly lit. To determine if the display has an acceptable number of pixel 
anomalies, follow the steps below:
1. Set the display image to one of the following colors: all-white, all-red, all-green, all-blue, or 
all-black display. Knowledge Base article 112125: “Service Diagnostics Matrix”, has the LCD 
Tester Diagnostic Utility that will generate these patterns on the screen.  
2. Using a jeweler’s loupe, pocket microscope, or other magnifying device, identify and 
count each pixel anomaly:
Bright subpixel anomaly = subpixel that is always on 
Dark subpixel anomaly = subpixel that is always off  
3. The number of acceptable pixel anomalies for this computer is:  
BrightUp to 3
DarkUp to 5
CombinationUp to 7
4. If the number of subpixel anomalies exceeds the acceptable number shown above, replace 
the LCD panel display assembly. Numbers outside the acceptable range would be
Bright4 or more
Dark6 or more
Combination8 or more
5. If the number of subpixel anomalies is acceptable, explain to the customer that the 
pixel anomalies are within specifications, and no repair is necessary.  
Important: Do not release the specifications to customers. Instead, inform them that a 
certain number of subpixel anomalies are considered acceptable, and these factors apply to 
all manufacturers using LCD technology—not just Apple products. 
When speaking with customers, please use the following explanation: 
• Active-matrix LCD technology uses rows and columns of addressable locations (pixels) 
that render text and images on screen. Each pixel location has three separate subpixels 
(red, green, and blue) that allow the image to be rendered in full color. Each subpixel has a 
corresponding transistor responsible for turning the subpixel on or off. 
• There are typically millions of these subpixels on an LCD display. For example, the LCD panel 
used in the Apple Cinema HD display is made up of 2.3 million pixels and 6.9 million red, 
green, and blue subpixels. Occasionally, a transistor does not work perfectly, which may 
result in the affected subpixel being turned on (bright) or turned off (dark). With the millions 
of subpixels on a display,  it is quite possible to have a low number of faulty transistors on an 
LCD. Therefore, a certain number of subpixel anomalies are considered acceptable. Rejecting 
all but perfect LCD panels would significantly increase the retail price for products using 
LCD displays. These factors apply to all manufacturers using LCD technology—not just 
Apple products.

Intermittent Shutdown
Unlikely cause:  hard drive, optical drive
Troubleshooting Shutdown Issues
Before troubleshooting shutdown issues, always do the following:
• Run the available Apple diagnostics to check for cause of previous shutdown(s). Running 
ASD also helps isolate any abnormal value reading from a thermal, voltage, or current 
sensor or from a fan speed meter.
• Collect all available information from the user on shutdown details: periodicity, power state 
when issue happens, running applications, running time before shutdown.
User-related shutdowns
A computer shutdown may be caused by user operation. Shutting down the computer (by 
selecting the Shut Down menu, by pressing the power button for at least 4 seconds, or by 
programming a timed shutdown in the Energy Saver preferences) should not be considered as 
a failure unless the power button or the magnetic sleep sensors are found to be defective.
Suggested steps for troubleshooting:
• Reset SMC.
• Check Energy Saver preferences settings.
• Test top case button and magnetic sleep sensor operation and secure connection to logic 
board.
Activity-related system shutdowns
These shutdowns are linked to system settings, devices drivers, applications, or operating 
system freezes.
• System could not finish the standard shutdown process and had to force shutdown.
• An installed watchdog detected that an application did not respond within the specified 
time. ( This watchdog can be enabled in Mac OS X Server Energy Saver preferences.)
Suggested steps for troubleshooting:
• Check the system logs and activity monitor utility for clues on the freezing process.
• Check for available software and firmware updates for installed device drivers, applications, 
or operating system.
• Start the system from a known-good and up-to-date bootable drive for issue reproduction. 
Power-related system shutdowns
These shutdowns are due to power management, poor connections or defective power 
sources.
• External or battery power source was removed.
• Battery went empty while computer was on.
• Battery went empty while computer was asleep.
