Replacing parts
•
Do not
transfer the BIOS chip from the old motherboard onto the new motherboard.
BIOS chips are not interchangeable.
•
Do not
reinstall system software at this time.
Reinstalling system software is not necessary when installing a new motherboard and can result in an error if done
before transferring options to the new motherboard (described on page 67 .)
•
Before you use the motherboard replacement dongle to sync the BIOS and options (for example, Fiery
Graphic Arts, Premium Edition, if applicable) from the hard disk drive to the new motherboard, enter
Service Mode (see page 67 ) and make sure that the new motherboard solves the problem that you are
troubleshooting.
The E-46A can remain in Service Mode indefinitely. Use Service Mode to carefully verify the new motherboard
before transferring options to the new motherboard.
Transferring options to the new motherboard permanently customizes the new motherboard. Once customized,
the motherboard cannot be returned to inventory or installed in another E-46A. If the new motherboard does not
solve the problem in Service Mode, do not transfer options. Return the new motherboard and motherboard
replacement dongle to inventory.
•
If you can verify in Service Mode that the new motherboard solves the problem that you are troubleshooting,
transfer options to the new motherboard using the motherboard replacement dongle included with the new
motherboard (see page 67 ).
•
Do not
remove the motherboard replacement dongle while transferring options to the new motherboard.
Removing the motherboard replacement dongle prematurely will corrupt the dongle and possibly damage the
motherboard. If either become corrupted, you must contact your authorized service/support center and order a
new replacement motherboard kit.
To replace the motherboard
1 If you are installing a new motherboard, do the following:
•
Unpack the new motherboard.
•
Open the load plate covering the CPU socket (see page 72 ) and remove the protective plastic cover on the CPU
socket on the new motherboard. Later, you will transfer the protective plastic cover to the CPU socket of the old
motherboard to protect the circuitry.
•
Remove the DIMMs from the old motherboard and install them on the new motherboard (see page 69 ).
•
Remove the CPU and cooling assembly from the old motherboard and install them on the new motherboard
(see page 70 ). Make sure that the cable cover (if present) remains on the cooling assembly fan cable when
transferring the cooling assembly to the new motherboard.
When transferring the CPU to the new motherboard, make sure to use the fresh thermal
compound that came with the new motherboard. For more information about the thermal
compound, see page 73 .
