HOW TO CHOOSE A LAPTOP

Laptops: - Laptops are designed mainly for mobility. So, main features of the laptop are weight and compact size. Next is Design and Display, performance, connectivity with other devices, Cooling system and easy updateable to next generation.

Weight and Size of Laptop:-  Weight and Size are proportional to each other, to reduce weight some of components are not assemble like CD/DVD/ BLUE RAY, WIFI, BLUE TOOTH, JACK-PORTS,

For better Performance processer used Duel core Quad core Octa core I3, I5, I7 in GHZ with ram 1, 2, 3, 4, 6 or8 GB RAM

The Intel Turbo Boost Technology allows a processor to dynamically increase its clock speed whenever the need arises. The maximum amount that Turbo Boost can raise clock speed at any given time is dependent on the number of active cores, the estimated current consumption, the estimated power consumption, and the processor temperature.

Basically, RAM minimises interaction with the hard disk, while cache minimises interaction with the RAM. Obviously, with a larger cache, more data can be accessed quickly. So when purchasing the laptop maximum catch in minimum budget is the best option.

Similarly, threading is also one more important thing which increases the cores. I3 execute only two threads at a time, I5 four threads and I7 execute eight threads for normal use I3 computer is enough for large graphic programs and for calculations I5 or I7 is must.

Intel and AMD are the two processors available in market. Choose the best suitable processor for your laptop performance. Both are working in good conditions. AMD is cheaper than Intel.

Cooling system: - The compact size of laptop heats-up rapidly for high-end program calculations and graphics. So, verify about Laptop running with enough cooling system before purchase.

Display: - The main advantage of LED is lower power usage and this is especially true for a laptop because battery power is always a big concern. LED technology allows richer colour and a brighter screen. It doesn’t take time to warm up as some old LCD screens will. With LED backlighting, the contrast is better and the colour is more accurate. These factors are difficult to notice especially since many LEDs will adjust brightness depending on the ambient light level which is another key factor that explains the push to adapt LED technology. LED backlight screens are lighter and thinner as well. Both qualities are highly desirable in the laptop market. This is the consideration that makes people pause their thought. LED screens are always more expensive than LCD

On comparing LCD and LED screen laptop, LED offers a lot of advantages, if you can afford it.

Screen sizes: laptops are available from 10.1”, 11.6”, 12.5”, 13.3”, 14,” 15.6”, 17.3” and 18.4” large screens have high quality and views because of its pixels per cm

Pixel per SQ.CM

4:3 SIZE                               16:9 SIZE (WIDE SCREEN)            16:10 SIZE

SVGA 800x600(4:3)                   WSVGA 1024X600           WSXGA 1680X1050

XGA 1024X768                          WXGA 1280X720           WUXGA1920X1200

SXGA(UVGA 1280X960)           HD 1360X768                                 XGA 1280X1024                                  FHD 1920X1080             

SXGA 1400X1050                       WQHD 2560X1440

XGA 1280X1024 (5:4)                 

UXGA 1600X1200

More pixels per sq.cm gives best picture quality.

For normal use online work and office work minimum pixels are sufficient

For high end graphics and watching videos XGA,SXGA,UXGA,HD, FHD WQHD, 2K, OR 4K is required but these are expensive.

Brightness and Contrast ratio adjusts the colour balance. Higher ratio of the B&C gives u best quality picture.

For gaming and online calling facilities HD web cam, mic, inbuilt speakers are required.

Improved Battery Life with Li-ion or Li- polymer Battery 3cell, 4cell, 6 cell, 8cell or 9 cell batteries are available in the market. Increase in number of cells, working time increases without charger. For common use 6 cell battery is enough. For small laptops 3 or 4 cell batteries are used, for graphics and long duration 8 or 9 cell battery is used.

Bluetooth, Wi-Fi and USB connectivity 2 or more required, Bluetooth 3.0 or Higher and Wi-Fi is must to connect network and for faster downloading. Laptop must be easy to connect to Projector or secondary monitor, Virtual reality unit or any other accessories and a wide range of Printers or plotters

Style: - The external and internal features of the products impress the Customers. Inbuilt useful apps, downloadable apps, hardness, light in weight, slimness, smooth touch and materials used to manufacture and finally colour. Warranty, part warranty or service warranty from purchase date is to be considered. Best warranty period is more than 1year. If the company has no option of giving more than one year warranty, it is better to take 2yrs more additionally.

So finally performance, style, warranty, easy service and price of the product decide which laptop is to be bought.
