Here are the keys to describe the data sheets of laptops and ask your choice without needing to be a specialist in new technologies.
It’s decided: you invest in a new laptop! Your beautiful enthusiasm falls quickly. Both on-line and on the shelves, the data sheets of the laptops subject to your consumer appetite are like vague hieroglyphs.
The short version and the detailed version of this analysis of the bowels of the machine generate confusion and embarrassment.
It’s the panic? Take a deep breath. We will decrypt point by point the 6 criteria to take into account to choose your new computer companion.
1. The screen
This is the best way to restrict the initial choice: select the screen size that best suits your needs.
As for TVs, the diagonal of laptop screens is expressed in inches: 11 inches (27.94 cm) for mobile machines to easily take with you on the move, 15 inches (38.1 cm) for the compromise comfort/portability or 17 inches (43.18 centimeters) for a laptop called to stay connected most of the time in the same place.
The size will affect the overall autonomy and configuration of the keyboard. To have a keypad to the right of the keys AZERTY, it will, for example, be necessary to opt for at least a model 15 inches.
The first source of energy consumption, a small screen will spare the battery for the benefit of autonomy.
2. The processor
The processor is the engine of your computer. It is he who will determine in priority the general speed of your machine, at the time of editing a photo, edit a video or just write a document in Word.
Two manufacturers share the market (Intel, AMD). One of the two, Intel, will be ubiquitous to the point of letting you think that AMD no longer exists, at least on the market of mobile processors. For office automation (Word, Excel), social networks, surfing the Internet and simple photo retouching tasks, for example, an Intel Core i3 processor will be more than enough.
The Intel Core i5 and even more the Intel Core i7 increase the power and the field of possibilities, at the price of a more salty addition and a battery more solicited.
The Atom and Celeron drastically lower the rating, to the detriment of modest performance.
3. The RAM
We would never dare to write: to prevent your laptop from paddling, invest in RAM.
RAM is the temporary memory of your computer, the equivalent of your short-term memory that will not forget to forget this bad game of words. The amount of random access memory (RAM) may not be indicated in the data sheet. Its importance is crucial, however.
The more RAM you have, the smoother and smoother the Windows operating system is, the more programs you can launch simultaneously, and the more the system has a memory pool for the current tasks.
Unless you have a tight budget that requires you to invest in a small, modest laptop, a total of 4 gigabytes of RAM is a minimum union. 8 gigabytes of RAM will be valuable when launching more demanding applications.
4. The hard drive
The bigger it is, the better? It is good to know that the adage has no more course.
Two hard drive families are now fighting over the favors of potential buyers. In the left corner, the good old mechanical hard drive to the old, whose massive storage capacity and low cost are tarnished by the reduced speed.
On such a disk with a capacity of 500 GB (gigas) or 1 TB (1 tera = 1000 gigs), you have a space worthy of the name to archive hundreds of photos, songs, videos .
In the right corner, SSD technology drives enjoy unparalleled speed. With such an ally, Windows starts in about ten seconds! The downside, the SSD is more expensive and delivered in lower storage capacity.
5. The graphics card
This section is mainly about video game enthusiasts. By default, the graphics chip (Intel HD Graphics 4400 in our example) structurally associated with the processor will be powerful enough for light-to-moderate photo editing, lightweight video editing, and legacy games.
If you opt for an Intel Core i3, i5 or i7 processor, the associated graphics chip will hold the road, without upsetting the power barriers.
Game lovers will break their piggy banks for a graphics card dedicated to their passion directly integrated into the machine, such as a Nvidia GeForce GTX 970M.
6. The Sidings
Worry about the version of Windows present on the coveted reference is not newsworthy.
At worst, you will inherit a laptop Windows 8.1 necessarily eligible for free upgrade to Windows 10.
As Wi-Fi will always be in order, side effects include the connection: the number of USB ports to connect your additional devices, the presence or absence of a memory card reader to extract images taken with your camera digital, the presence or absence of a webcam, etc.
