Processor performance is a common concern for many Acer laptop users. In fact, as software and gaming programs improve, a processor upgrade may be necessary to operate these applications. The Acer Aspire 5100 laptop comes with a 2.6-GHz dual-core processor. The Aspire 5100 is compatible with the AMD Turion 64 X2 Dual-Core chip, and/or the Mobile AMD Sempron processor chip. Unlike with most laptop processors, removing and installing the Acer 5100 laptop's processor requires very little disassembly.
Shut down the laptop, and disconnect the AC power cable from its socket. Close the display panel, and place the laptop face down. Rotate the laptop so the front opening edge is facing toward you.
Slide the battery release lever to the right. Remove the battery pack from its compartment in the upper right corner of the laptop's bottom side.
Remove the large hardware compartment cover, and its four retaining screws from the laptop's upper right corner just below the empty battery compartment. This hardware compartment houses the memory, wireless and processor modules.
Remove the two Phillips-head screws securing the heat sink inside the hardware compartment. The heat sink is a metal piece with a large copper pipe extending from it. The heat sink sits directly on top of the processor. Carefully lift the heat sink out of the laptop, and set it aside.
Turn the processor's flathead locking screw in the counterclockwise direction as far as you can. Grasp the outside edges of the chip with your fingertips. Lift the processor out of the laptop, and set it aside.
Repeat this procedure in reverse to install the new processor. Apply a thin coat of thermal grease evenly to the new processor's surface before replacing the heat sink.
Use an antistatic wrist strap as you remove and install the new processor chip. This will prevent electrical damage to the laptop's motherboard.
