Microprocessor
Attention: Do not open your computer or attempt any repair before reading and understanding the Chapter
1 "Read this first: Important safety information" on page 1.
Depending on the model, your computer might come with one or two microprocessors. For computer
models with one microprocessor, the microprocessor is installed in the microprocessor socket. And the
microprocessor socket 2 is protected by a plastic socket cover.
CAUTION:
The heat sink and microprocessor might be very hot. Before you open the computer cover, turn off
the computer and wait several minutes until the computer is cool.
Notes:
• Ensure that you install the correct type of microprocessor option your computer supports. When two
microprocessors are installed, both must be identical.
• For E5-1600 v4 series microprocessors, the computer can support only one installed. If you want to install
two microprocessors into your computer, use the E5-2600 v4 series microprocessors.
• Your microprocessor, socket, and socket cover might look slightly different from the illustrations in this
topic.
To replace a microprocessor, do the following:
1. Prepare your computer. See "Preparing your computer and removing the computer cover" on page 99.
2. Remove the direct cooling air baffle. See "Direct cooling air baffle" on page 101.
3. Lay the computer on its side for easier access to the system board.
4. Remove the heat sink and fan assembly. See "Heat sink and fan assembly" on page 161.
5. Locate the correct microprocessor socket on the system board. See "Parts on the system board"
on page 35.
6. Gently press down the small handle
from the secured position. Then, open the other small handle
Ensure that the small handles are in the fully open position.
