CAUTION: If either the processor or the heat sink is replaced, use the thermal grease provided in the kit to ensure that thermal
conductivity is achieved.
NOTE: A new processor ships with a thermal pad in the package. In some cases, the processor may ship with the thermal pad
attached to it.
Procedure
1 Ensure that the release lever on the processor socket is fully extended in the open position. Then align the notches on the processor
with the tabs on the processor socket and place the processor in the processor socket.
CAUTION: The pin-1 corner of the processor is marked with a triangle that must align with the triangle marking on the pin-1
corner on the processor socket to ensure that the processor is properly seated. When the processor is properly seated, all
four corners are aligned at the same height. If one or more corners of the processor are higher than the others, the
processor is not seated properly and closing the securing bracket may permanently damage the processor.
CAUTION: Ensure that the securing-bracket notch is positioned underneath the alignment post.
2 When the processor is fully seated in the socket, close the securing bracket.
3 Pivot the release-lever down and place it under the tab on the securing bracket.

BIOS overview
CAUTION: Unless you are an expert computer user, do not change the settings in the BIOS Setup program. Certain changes can
make your computer work incorrectly.
NOTE: Before you change BIOS Setup program, it is recommended that you write down the BIOS Setup program screen
information for future reference.
Use the BIOS Setup program for the following purposes:
• Get information about the hardware installed in your computer, such as the amount of RAM and the size of the hard drive.
• Change the system conguration information.
• Set or change a user-selectable option, such as the user password, type of hard drive installed, and enabling or disabling base devices.
Entering BIOS setup program
1 Turn on (or restart) your computer.
2 During POST, when the DELL logo is displayed, watch for the F2 prompt to appear, and then press F2 immediately.
NOTE: The F2 prompt indicates that the keyboard is initialized. This prompt can appear very quickly, so you must watch for
