Video - Dell Laptop CPU Replacement Tutorial

By Parts-People

BTH Webmaster message: It's very difficult to determine if a failure is caused by the CPU because many other components can cause the same symptom when they fail. Some symptoms of a bad CPU are: system fails to boot, system re-boots intermittently, general protection fault, illegal operation, stop error, or BSoD (Blue Screen Of Death). Actually, CPUs rarely fail, and about the only way to determine if the CPU is causing the failure is to swap it out with a known working CPU of the same type and speed. Since this is difficult, the best bet is to first rule out every other possibility. But if you feel a bad CPU is causing your problem, this video shows you how to replace it in a Dell laptop.

Warning: Avoid static discharge by grounding yourself using a wrist strap or by touching a bare metal surface like a connector on the back of the laptop and remove all of the power including the battery and power adapter.

Make sure all data is backed up before removing or replacing your hard drive. Laptop hard drives are very sensitive and can be damaged easily. Handle with care. Performing your own repairs may void your warranty.


1. Unscrew the seven (7) retaining screws to remove the access base cover.

2. Lift and remove the access base cover door.

3. Remove the single retaining screw by the CPU fan.

4. Loosen the six (6) CPU heat sink retaining screws.

5. Unplug the CPU fan.

6. Remove the heat sink and fan assembly.

7. Turn the CPU locking screw counter-clockwise and lift the CPU straight up.

8. Set the new CPU into the socket by aligning the corner arrow with the two missing pins on the socket. Do not try to force the CPU into the socket. If it's aligned correctly, it will seat easily.

9. Turn the CPU locking screw click wise to secure the CPU in place.

10. Replace the heat sink fan assembly and tighten down the six (6) retaining screws in numerical order.

11. Replace the single retaining screw by the fan.
