Sony VGN-NS315D Cpu

Your laptop CPU is the primary hardware component that processes data for the computer. The speed of your unit largely depends on the clock speed and model of CPU within your system. In order to replace the old processor with a new CPU in your Sony system, be careful so you do not damage the replacement CPU. You should make sure you are going to replace a bad piece of hardware that is actually bad, as processors rarely go bad. Purchasing and replacing an old CPU can be a daunting task for anyone to do themselves, as there are a lot of things that could possibly happen that would render the new CPU useless.
