Reset the SMC (power manager) as described in “
3.  Resetting the System Management 
Controller (SMC)”  under “Troubleshooting Tips and Tricks” in the previous section.
Make sure the power adapter is connected to a known-good outlet using the AC power cord, 
4.  
not the duckhead. If the intermittent behavior goes away, recommend using the AC cord to 
provide a grounding path for static.

3. 
replace the display assembly.
Replace the logic board.
4.  
Miscellaneous Symptoms
The Date and Time settings reset repeatedly
Note: Resetting the power manager and/or PRAM resets the date and time. The MacBook Pro 
uses a non-rechargeable lithium battery.
Do a backup battery test:
1.  
Set the date and time.
• 
Perform a Shut Down from the Apple menu.
• 
Remove the main battery and disconnect the power adapter for 10 minutes.
• 
Connect the power adapter, insert the battery, and power on the computer.
• 
If the date and time were lost the backup battery may be dead or discharged.
• 
Remove main battery from the unit and leave it plugged in for at least 5 hours.
• 
Replace the backup battery.
2.  
Replace the logic board.
3.

Feet came off the bottom case
Replace the missing foot or feet.
Sleep LED does not come on when lid is closed
Put the computer to sleep using the menu option. If the sleep LED goes on, the computer is 
1.  
not detecting a closed display. If the LED does not go on, skip to step 3.
Place a magnet over the sleep sensor board in the top case. If the system goes to sleep, 
2.  
replace the magnet in the display housing.
Check that the sleep sensor in the top case is plugged in.
3. 
Check that the sleep LED is plugged into the logic board.
4.  
Connect a USB mouse. Short the power on pads on the logic board to boot the system and 
5. 
use the mouse to put the system to sleep from the menu. Measure the voltage at the LED 
connector. If power is present, replace the bottom case.
Replace the logic board.
6.  
Unit unusually hot
This computer runs hotter than previous models. However, the normal operating temperature 
is well within national and international safety standards. Nevertheless, customers may be 
concerned about the unit overheating. To prevent an unneeded repair, you can compare a 
customer’s computer to a running model, if available, at your repair site.
Verify that the customer uses the computer while it is placed on a flat, hard surface.
1.  
Verify that the computer is hotter than expected for normal operation. If possible, compare 
2.  
how hot the computer case feels with how hot the case of a running display model feels.
If the computer is running at a temperature comparable to the test model, refer the 
3. 
customer Knowledge Base article 30612: Apple Portables: Operating Temperature 
Use Activity Monitor to check for runaway applications.
4.  
Check the processor speed.
5. 
Is the processor speed running at the setting the customer set?
6.  
Yes: Continue with the next step.
No: The computer could be overheating. The operating system will automatically reduce the 
processor speed if the computer starts to get too hot. Continue with the next step.
Check for a failed fan.
7.  
Can you hear the fan running?
8.  
Yes: Continue with the next step.
No: This computer has only one fan. If the unit feels too hot and you do not hear a fan 
running or cannot feel the air venting over the top of the keyboard, the fan may have failed. 
Proceed to the Take Apart procedure for replacing the fan.

Check for misplaced or inadequate thermal grease.
9. 
Each processor chip should have .01 to .12 cc (one-third of a single syringe) of grease on it. 
It should look completely covered. See the Heatsink chapter of the Take Apart section for 
complete details.
Is the thermal grease applied in the right places and in the right amount, according to the 
10.  
service manual?
Yes: You have eliminated all the immediately known potential causes of an unusually hot 
unit. Proceed to the Systematic Fault Isolation step of the troubleshooting flowchart.
No: Apply the thermal grease correctly, according to the instructions in the service manual 
then proceed to the Verify Repair step of the troubleshooting flowchart.

							MacBook Pro 17-inch (original, Core 2 Duo, 2.4/2.6GHz, 2008) Troubleshooting — Architecture 19 5
Architecture
The architecture of the 17-inch MacBook Pro is based on the Intel Core 2 Duo microprocessor and 
two ICs, the North Bridge memory controller and the South Bridge I/O controller, connected to 
each other by a Direct Media Interface (DMI) bus. 
The North Bridge provides the bridging functionality among the processor, the memory system, 
the DMI bus, and the 16-lane PCI Express bus to the graphics controller. 
The South Bridge supports these components:Ultra ATA/100 bus for the optical drive (running at UATA/66)
• 
A 1.5 Gbps Serial ATA (SATA) bus for the hard disk drive
• 
1-lane PCI Express link for the AirPort Extreme module
• 
SPI bus, direct memory access bus to the boot ROM
• 
USB 2.0 controller, which in turn supports the Bluetooth module, IR receiver, built-in iSight 
• 
camera, built-in trackpad and keyboard, ExpressCard/34 slot, and 3 external USB 2.0 ports
Channel to the audio subsystem
• 
1-lane PCI Express link for the Ethernet PHY
• 
33 MHz, 32-bit internal PCI bus to the FireWire 400 (1394a) and FireWire 800 (1394b) OHCI 
• 
and PHY
1-lane PCI Express link and one USB 2.0 interface for the ExpressCard 34 mm slot
• 
Direct Media Interface (DMI) bus
• 
A DMA controller internal to the South Bridge supports LPC DMA (low pin count direct memory 
access). The DMA controller has registers that are fixed in the lower 64 KB of I/O space. The DMA 
controller is configured using registers in the PCI configuration space.
Figure 1 (see following page) provides a simplified block diagram of the North Bridge and South 
Bridge ICs and the buses that connect them together.
