Replacing a Microprocessor
Your computer comes with either an Intel
Pentium
II microprocessor, a Pentium
Intel III microprocessor, or an Intel Celeron
microprocessor installed on the system
board.
For the latest information on microprocessor upgrades available for your computer,
contact your IBM reseller or IBM marketing representative. If you do upgrade the
microprocessor, use the instructions that come with the upgrade along with the
instructions in this publication.
Note:
Upgrading a microprocessor may require a BIOS update. After replacing or
upgrading your processor, you may get a '167' POST error code. If you get
this error, you must update the BIOS.
CAUTION:
The microprocessor and heat sink will be hot if the computer has been running.
To avoid the possibility of a burn, if the computer has been on, let the
microprocessor and heat sink cool for 10 minutes before continuing with the
procedure.
Before you begin
Read “Electrical Safety” on page 3 and “Handling Static-Sensitive Devices”
on page 4.
Read the instructions that come with the optional device.
Turn off the computer and all other connected devices.
Disconnect all cables attached to the computer.
Attention:
The presence of 5 V standby power might result in damage to
your hardware unless you disconnect the power cord from the wall before
opening the computer cover.
Remove the computer cover (see “Disconnecting Cables and Removing the
Cover” on page 5), and lay the computer on its side.
Note:
The heat sink in your computer might look different from the one shown.
