Replacing the Microprocessor Module

NOTICE:

Disconnect the computer and attached devices from electrical outlets and remove any installed batteries.

NOTICE:

To avoid ESD, ground yourself by using a wrist grounding strap or by periodically touching unpainted metal on the computer.

NOTICE:

To ensure maximum cooling for the microprocessor, do not touch the heat transfer areas on the thermal cooling assembly. The oils in your skin

reduce the heat transfer capability of the thermal pads.

NOTICE:

When removing the microprocessor module, pull the module straight up. Do not bend the pins.

NOTICE:

To avoid damage to the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor when removing the cam lock

screw (see "

Microprocessor Cam Lock Screw

").

NOTICE:

Hold the microprocessor down while turning the cam lock screw to prevent intermittent contact between the cam lock screw and

microprocessor.

NOTICE:

If you received a flash BIOS update program diskette or CD with the replacement microprocessor, you must update the BIOS after replacing

the microprocessor module. For instructions on updating or reflashing the BIOS, see the Dell Portable Computer BIOS Update Guide.
