Things to Consider While Purchasing a Laptop


If you have decided to buy a laptop, you should consider few important facts before deciding. Buying a laptop is not like buying a desktop, the main difference is, it can't be upgraded or modified as you like in future. For example, you can't add an additional hard disk to increase the disk space or replace the processor, even upgrading RAM would be expensive. So it is like a onetime purchase, because of that when you do the purchase, do a through study and purchase it. Your laptop should be compatible with existing and other forthcoming applications in future.

Major Points to Consider While purchasing a Laptop


1) The Purpose
I think this defines everything, why do you want to buy a laptop? , for playing game or do basic day to day activities, or just for internet usage or to do some video editing or 3D designing ?

Depending of the purpose, the hardware configuration requirement changes so that cost of a laptop too.
You can't buy a laptop to play high graphics games for the cost of ordinary low level laptop which was made for internet browsing only.

Decide the purpose of purchase and think to manage with the laptop for next 2 to 5 years.


2) Price
Once you have decided the purpose, you will get a rough idea of starting price of your laptop which can full fill your purpose.

Now, you can optimize each hardware configuration based on your budget limit. Also, decide the brand of the laptop depending on cost, warranty and support.

3) RAM (Memory)
This is the main part of laptop. Somehow I feel RAM size of a computer (laptop or desktop) is more important than processor. Most of the recent programs uses or requires more RAM instead of processor speed. Also, frequently RAM of a computer touches threshold limit than usage of CPU. Obviously we run out of available free RAM resources most of the time.

Therefore when you buy a laptop, better go with maximum RAM size you and laptop could afford.  You must consider the RAM usage of Operating System too, because OS also will consume certain amount of RAM all the time.

I prefer to go  with 8 GB RAM, if not, 4 GB RAM but I will keep one memory slot as free, so in future I can buy another 4 GB RAM and upgrade it.

4) Processor Speed and Type
This is mainly decided by the purpose of laptop. There are several types of processors you can think of it, like Atom, Celeron, AMD, Intel dual core, Intel Core i series and more. Each processor is having maximum capability which should match your purpose.

You can't expect an Atom processors to run 3D video games or any kind of 3D editing software.
Always before decide a processor for laptop, better learn the full configuration of it. You should consider these aspects in a processor,

Speed,
Number of cores and threads,
L2 Cache size,
Supported Memory types.

These are the core things or considerations you should check while buying a new laptop.

Remember: Laptop is a onetime purchase, you can't upgrade or modify the configurations as you like do in desktop computers.

There are some more important facts you should consider, which will be shared in next post.
