Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Owner's Manual.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a processor by its edges, not by its pins.
NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not
covered by your warranty.
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with
locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and
aligned.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
1.
Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.
2.
Turn off your computer.
3.
If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
4.
Disconnect any telephone or telecommunication lines from the computer.
5.
Disconnect your computer and all attached devices from their electrical outlets, and then press the power button to ground the system board.
NOTICE: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.
6.
Remove any installed PC Cards from the PC Card slot.
7.
Close the display and turn the computer upside down on a flat work surface.
NOTICE: To avoid damaging the system board, you must remove the main battery before you service the computer.
8.
Slide and hold the battery-bay latch release on the bottom of the computer, and then remove the battery from the bay.

Microprocessor Module
Dell™ Inspiron™ 1150 Service Manual
Removing the Microprocessor Module
CAUTION: Before performing the following procedures, read the safety instructions in your Owner's Manual.
CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of
your computer's electronic components. You can do so by touching an unpainted metal surface.
NOTICE: Press and hold the microprocessor down by applying slight pressure to the center of the microprocessor while turning the cam screw to
prevent intermittent contact between the cam screw and microprocessor.
NOTICE: To avoid damage to the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor when turning the cam screw.
1.
Follow the instructions in "Before Working Inside Your Computer."
2.
Remove the keyboard.
3.
Remove the EMI shield.
4.
Remove the microprocessor thermal-cooling assembly.
NOTICE: When removing the microprocessor module, pull the module straight up. Be careful not to bend the pins on the microprocessor module.
5.
To loosen the ZIF socket, use a small, flat-blade screwdriver and rotate the ZIF-socket cam screw counterclockwise until it comes to the cam stop.
The ZIF-socket cam screw secures the microprocessor to the system board. Take note of the arrow on the ZIF-socket cam screw.
1 ZIF-socket cam screw
2 ZIF socket
3 microprocessor module
4 pin-1 corner of
microprocessor
5 triangle on system board
6.
Use a microprocessor extraction tool to remove the microprocessor module.
Installing the Microprocessor Module
NOTICE: Ensure that the cam lock is in the fully open position before seating the microprocessor module. Seating the microprocessor module properly in
the ZIF socket does not require force.
NOTICE: A microprocessor module that is not properly seated can result in an intermittent connection or permanent damage to the microprocessor and
ZIF socket.
1.
Align the pin-1 corner of the microprocessor module so that it points to the triangle on the system board, and insert the microprocessor module into the
ZIF socket.
When the microprocessor module is correctly seated, all four corners are aligned at the same height. If one or more corners of the module are higher
than the others, the module is not seated correctly.
NOTICE: Hold the microprocessor down while turning the cam screw to prevent intermittent contact between the cam screw and microprocessor.
2.
Tighten the ZIF socket by turning the cam screw clockwise to secure the microprocessor module to the system board.
3.
Wipe the thermal grease off of the microprocessor thermal-cooling assembly with a clean paper towel.
4.
Squeeze all of the contents of the thermal grease packet (provided with the kit) on to the microprocessor thermal-cooling assembly.
5.
Replace the microprocessor thermal-cooling assembly.
6.
