Things you should keep in mind before buying a laptop

1. Set your budget amount


2. Choose the processor that satisfy your needs (Always choose Intel processors)

i. Light users (i3)

Intel® Core™ i3 Processor
Visibly Smart performance starts here
Responsive performance Four-way multitask processing Built-in visual enhancements 3M cache 
Intel® HD Graphics

ii. Mid users (i5) *Most popular*

Intel® Core™ i5 Processor
Visibly Smart performance with a boost
More responsive performance Four-way multitask processing Automatic burst of speed when you need it Built-in visual enhancements 3M cache 
Intel® HD Graphics

iii. Heavy users (i7)

Intel® Core™ i7 Processor
Visibly Smart performance at its best
Top-of-the-line performance Eight-way multitask processing Automatic burst of speed when you need it Built-in visual enhancements 8M cache 
Intel® HD3000 Graphics


3. 32bit or 64bit 

32-bit Windows has an address space of 4GB. Part of that is used by system BIOS and graphics memory.

64-bit Windows has an address space of 16GB. Part of that is used by system BIOS and graphics memory.

64-bit OS can emulate 32-bit programs.


4. CPU series

M series = (More power Less battery life)

U series (used in ultrabooks) = (Less Power More battery life)

Difference in power about 14% - 20%


5. RAM (Most laptops have 2 x SO-DIMM socket for expansion up) At least get DDR3 SDRAM 4GB 

Most medium to high end RAM runs at high enough frequencies to handle most applications with ease so as long as you have a high enough amount for your usage then you should be fine. Highest RAM frequency for laptops is DDR3 SDRAM 1600 MHz.


6. Graphics card

If you are not going to use your laptop for heavy gaming then you are good with the integrated graphic card.

Fast game action and impressive 3D visuals have gone mainstream. 3rd generation Intel®Core™ processors integrated with powerful graphics engines by Intel® HD Graphics now give you responsive gaming performance and realistic visuals, WITHOUT THE COST of a separate graphics card.

Laptops with dedicated graphics card are more expensive.

High end dedicated graphics cards LIST


7. Hard disk drive

A 5400 rpm drive spins 25% slower than a 7200 rpm drive, increasing bearing life by at least that amount.

(5400 rpm 500-750 GB + 24 GB SSD for OS) is preferable

OR

(5400 rpm 500-750 GB)

OR

(256 SSD)

But SSD hard drives are expensive.


8. Display

14" - 15.6" LED back-lit with minimum resolution of 1366 x 768
