Lenovo ThinkPad T400S Cpu

The CPU is the primary hardware component that processes information that the software uses. The speed of your unit largely depends on the clock speed and type of CPU in your laptop. Installing a new CPU can be a daunting task for even a professional, as there are a plethora of things that could go bad. You should make sure you are going to replace a bad piece of hardware that is actually bad, as a CPU rarely goes out unless it was overused or overclocked. While replacing the CPU in your Lenovo system, do some research as to how to do it properly so you do not damage the replacement CPU.
