What to consider when buying a Laptop

1. CPU(Processor): This is very important when purchasing a PC, because the speed in which your processor calculates and process instruction given determines how quick its response time will be. It is usually in GHz, when buying so the higher the frequency(Hz) the better the performance. Examples;
Intel Processor
32 bit order of low to high: Celeron> Pentium M > Celeron M > Intel Core .> Dual Core
64 bit order of low to high: Xeon> Pentium Dual Core> Celeron M> Intel Pentium(Core i3,i5,i7)

AMD Processor
a. AMD sempron is a 32 bit processor, which has only one processor core. It supports the HyperTransport technology. .
b. AMD Athlon 64 x 2 dual core can be used to run 32 bit applications and 64 bit applications. It is equipped with two cores. One of the processing cores is located in the chip. It has a faster speed compare to AMD sempron. Because it offers faster speed, it can handle multiple open programs efficiently.
c. AMD opteron provides the capability to perform 32 bit computing and 64 bit computing. AMD Opteron is built based on the Direct Connect Architecture. AMD Opteron is originally designed to run 32 bit applications. It is used in 1 way – 8 ways server and workstations.

2.Sockets: Ensure your laptop has enough USB, firewire or other ports(parallel, serial, s-video) depending on your needs.

3. Screen-size: Depending on what you want to use it for, you can choose from a variety of screen size which is measured in inches (12", 15", 17", 21" ).

4. Hard Drive: If you are the type that deals with software and Data, then you need a huge storage space. For a standard user a 160GB HDD is ok or you could decide you want more.

5. RAM: The more the RAM, the better the PC can handle more task in conjunction with the processor. For someone who work on softwares which requires Graphics, will suggest you go for at least 4GB RAM on a windows 7. If you have a lesser RAM, and your PC requires more RAM to run an Application then it will start eating up into the HardDisk to form a Virtual Memory. This has its down size, because you will be over working the HDD. So its better you get another higher RAM.

6. Battery Life: If battery life is very important to you, then check if the manufacturer offers a long battery life.

7. Peripherals: Those the laptop has Bluetooth, wireless, webcam, Optical Drive etc.
