1. Processor (CPU)
Processor refers to CPU (Central Processing Unit) which is the brains of the computer where most calculations take place. In terms of computing power, processor is the most important element of a computer system. Without it, a computer cannot even boot up or running. The performance of processors determines the speed and the performance of the notebook as well. Whether a computer system can run smooth or not is also depend on the performance of processor.
Most of the processors of notebooks can be divided into two types, which are Intel based and AMD based. AMD chips usually less expensive and notebooks based on them are cheaper then Intel based notebooks. But compared to AMD chips, Intel chips consume less power so

This will let us know what upgrade potential the system has. Then, we need to look at the ways in which you intent to use your laptop in order to determine the right amount of system memory, or RAM needed. If you only need your laptop to perform the usual tasks of emailing, typing on word processing, spreadsheets, etc. then a standard RAM of 256MB should be enough, which is a common configuration on most laptops, hence you probably won’t need to spend more for more RAM. However, for storing digital photographs and videos or other multimedia contents, you should equip your laptop with as much RAM as it can accommodate. Certainly the more memory in a notebook system the better, but there are other concerns regarding memory in notebooks. Notebooks are generally more restricted in the amount of memory that can be installed into a system.
The rule of thumb that use for all computer systems for determining if it has enough memory is to look at the requirements of the software intended to run. Pick up the boxes for each of the applications and the OS that you intend to run and look at both the "minimum" and "recommended" requirements. Typically you want to have more RAM than the highest minimum and ideally at least as much as the highest listed recommended requirement.
