To take advantage of future options in speed and functionality, you can
replace the microprocessor.
Each microprocessor and its associated Level 2 cache are contained in a pin grid
array (PGA)
package that is installed in a ZIF socket on the system board. The following
subsection describes how to install or remove the microprocessor.
To replace the microprocessor, perform the following steps.
|
NOTE: Only a technically knowledgeable person should perform
this procedure. |
|
CAUTION: See
"Protecting Against Electrostatic Discharge" in the safety instructions
in your System Information document. |
|
CAUTION: The
microprocessor and heat-sink assembly can get extremely hot during system operation. Be
sure the assembly has had sufficient time to cool before you touch it. |
|
CAUTION: When

| 3 |
Microprocessor |
| 4 |
ZIF socket release lever |
|
- Lift the microprocessor away from the ZIF socket and leave the release
lever in the upright position so that the socket is ready for the
replacement microprocessor (see Figure 15).
|
NOTICE: Be careful
not to bend any of the pins when removing the microprocessor. Bending
the pins can permanently damage the microprocessor. |
- Unpack the new microprocessor.
If any of the pins on the microprocessor appear bent, contact technical
support.
- Identify the pin-1 corner of the microprocessor by locating the tiny gold
triangle that extends from one corner of the large central rectangular area.
The gold triangle points toward pin 1, which is also uniquely
identified by a square pad.
|
NOTE: Identifying
the pin-1 corner is critical to positioning the microprocessor correctly. |
- Align the pin-1 corner of the microprocessor with the pin-1 corner of the
microprocessor socket.
- Install the microprocessor in the socket (see Figure
15).
|
NOTICE: Positioning
the microprocessor incorrectly can permanently damage the microprocessor and
the system when you turn on the system. When placing the microprocessor in
the socket, be sure that all of the pins on the microprocessor enter the
corresponding holes. Be careful not to bend the pins. |
If the release lever on the microprocessor socket is not positioned all the
way up, move it to that position.
With the pin-1 corners of the microprocessor and socket aligned, set the
microprocessor lightly in the socket and make sure all pins are matched with the
correct holes in the socket. Because the system uses a ZIF microprocessor
socket, do not use force, which could bend the pins if the microprocessor is
misaligned. When the microprocessor is positioned correctly, it drops down
into the socket with minimal pressure.
When the microprocessor is fully seated in the socket, rotate the socket
release lever back down until it snaps into place, securing the microprocessor.
- Place the heat sink you removed in step 5 on top of the microprocessor (see Figure 15).
|
CAUTION: Ensure
that the thermal pad on the underside of the heat sink is not damaged
during handling. |
- Orient the securing clip as shown in Figure 15.
- Hook the end of the clip without the heat-sink latch to the tab on the edge
of the socket.
- Push down and pivot the heat-sink latch until the hole on the clip latches
onto the ZIF socket tab.
Make sure that the latches engage.
Replace the system cover.
- Reconnect the system and peripherals to the power source, and then turn on the
system.
|
NOTE: To perform the next step, you
must use the console redirection function on the serial port (COM1). See the System
Administrator's Guide for more information about console redirection. |
From console redirection, check to see that the presence of the new processor
is listed during the POST. As the system boots, it detects the presence of the
new processor and automatically changes the system configuration information in the BIOS Setup
utility.
- Run the system diagnostics to verify that the new microprocessor operates
correctly.
See "Running the System
Diagnostics" for information about
running the system diagnostics and troubleshooting any problems that might occur.
|
NOTE: Parts of
this procedure require you to use the console redirection function on the
serial port (COM1). See your System Administrator's Guide for information about
connecting to the system through console redirection. |
The system battery maintains system configuration, date,
and time information in a special section of memory when you turn off the system. The
operating life of the battery ranges from 2 to 5 years, depending on how you use the
system (for example, if you keep the system on most of the time, the battery gets little
use and, thus, lasts longer).
You might need to replace the battery if an incorrect time or
date displays during the boot routine, along with a message about wrong
time, invalid configuration information, or bad CMOS checksum.
|
NOTE: To perform this procedure, you
must use the console redirection function on the serial port (COM1). See the System
Administrator's Guide for more information about console redirection. |
To determine if the battery needs replacing, perform the following steps:
- Re-enter the time and date through the BIOS Setup
utility.
- Turn off and disconnect the system from the electrical outlet for a few
hours.
- Reconnect and turn the system on again.
- Enter the BIOS Setup utility.
If the date and time are not correct in the BIOS Setup utility, replace the
battery.
|
NOTES: Some software
might
cause the system time to speed up or slow down. If the system seems to operate normally
except for the time kept in the BIOS Setup utility, the problem might be caused by
software rather than by a defective battery. If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation is not caused by a defective battery. |
You can operate the system without a battery; however, the system configuration
information maintained by the battery in NVRAM is erased each time you shut down the
system. Therefore, you must re-enter the system configuration information and reset the
options each time the system initializes, until you replace the battery. The battery is a 3.0-volt (V), coin-cell CR2032-type
battery.
To remove the battery, perform the following steps.
|
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it
from its power sources. For more information, see the safety precautions in your
System Information document. |
|
CAUTION: There is a danger of a new battery
exploding if it is incorrectly installed. Replace the battery only with the same or
equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer’s instructions. |
- Enter the BIOS Setup utility and, if possible, make a printed copy of the
BIOS Setup
screens.
See "Using the BIOS Setup Utility."
- Shut down the system, including any attached peripherals, and disconnect the system from the electrical outlet.
|
CAUTION: Read the safety instructions
in your System Information document. |
- Remove the system
cover.
- Remove the battery (see Figure 9 for the battery location).
Pull the tab back on the battery socket and remove the battery from its
socket with your fingers.
- Pull the tab back on the battery socket and install the new battery with the side labeled "+"
facing up (see Figure 16).
