How to choose to buy a basic laptop
Here are some criteria for how to buy a laptop for everyone, please refer together.
Check the screen
Check the screen for dead spots before deciding to buy a laptop. First, download the different black and white and blue wallpapers yourself (you can find it on Google very easily).
Then open up the black image and set it to full screen, then turn the brightness to maximum. When any pixel isnt black, its weird. In the case of a high-resolution screen (2K or 4K) the pixels will be quite small, so please pay close attention.
There is an error in the corner of the screen
Next open up white and do the same test. Make sure all pixels are bright. Next check the exposure, that is, you need to wait until night or in a dark room, then you can re-open the black image and set the brightness to maximum. Most IPS panels have slight exposure to light due to the technology, but if you notice any uneven light beams, think twice before choosing it. Finally, repeat the experiment with a light blue background (the color makes it easier to spot problems).
Check the laptops frame
Ensure that the lap has no problems with the bezel or screen with the naked eye.
Please "look" carefully every detail from the body, bezel, screen, front, back ... to make sure that your device has no scratches. Everyone wants a brand-new device, right? And yet, how to choose to buy a laptop also needs to check the connection ports to see if they are compatible with the outside.
Test the keyboard
The indispensable way to choose to buy a laptop is "looking at" the keyboard. Make sure all keys are not stuck. Press each key repeatedly for a more objective evaluation. The Enter, Shift and Spacebar keys need to be spent more time as they are larger and more prone to problems.
Check the keyboard thoroughly before deciding to buy.
Check the backlight function of the device in the dark, you must make sure all the keys are working properly.
TrackPad / TouchPad
Take the time to move the mouse across the screen to check input lag and overall responsiveness. Make sure that the right mouse and left mouse button function properly by clicking multiple times.
Test the TouchPad to see if its having any scrolling problems.
Another major bug with the TouchPad is that scrolling is pretty much the problem. Therefore, open a page with lots of content and scroll the page up with 2 fingers to ensure a smooth scrolling process.
Check CPU and GPU
It is very rare that the CPU and GPU fail from opening the box. To know if they have a stable operation and effective heat dissipation, you should try running computer performance testing software such as: GPU-Z, Cinebench, TSBench, Throttlestop, LinX, Unigine Heaven, Unigine Valley ...
