Consumers have the greatest demand for computer used products. On the purchase of a system unit or laptop, you can save a lot, if, as they say, take "with hands". But here there are their pitfalls, t. You can not be sure of honesty and good faith of the seller.

If you want guarantees, purchase a laptop in a specialized store, for example, by link hottrader. Com. Ua. However, in any case, it is useful for everyone to get acquainted with the main recommendations regarding the purchase of used equipment. How to properly and competently buy used laptops? What to look for first?.

Meet on clothes. First, look at the appearance of the device. On it there should be no deep scratches and obvious damages. It is necessary to pay attention to the external connectors:.

Under the headphones;.

USB;.

DisplayPort;.

RJ-11 and others.

For greater reliability, check the operation of the outputs by inserting the appropriate cable. Pay attention to charging: make sure the cord is securely in the connector, if there are any damages on it. Do not forget to check the operation of the indicators and keys. Sticking is very difficult to eliminate, which is important to consider when buying.

What with age?.

It is not recommended to buy an old laptop too much, since the parts have the property of morally and physically obsolete. Another disadvantage of the long-lived worker is poor productivity. Old laptops are not designed for new software and applications, which negatively affects the technical capabilities of the device. Experts consider the optimal working period of the laptop is 1-1.5 years. Therefore, ideally, it is better to dwell on the model, which was used no more than two years.

The brand has a value When choosing a manufacturer, it should immediately clarify whether there are any service centers of this manufacturer in the city. Otherwise, it will be difficult to resolve issues with the search for parts and repairs. For example, Sony products are very high quality, but quite rare, so its repair will be costly. It is better to look after a second-hand laptop Dell, Asus or Acer. With them, such a problem does not arise, because brands are very common.

Let's talk about the characteristics of the main criteria for choosing "hardware" (screen, processor, the amount of RAM and hard drive, gamers should take into account the characteristics of the video card) simple. You can follow these recommendations:.

Monitor. When buying a used device it is enough to be guided by the integrity and size of the screen. In this case, only these characteristics are significant. Glossy or matte screen - these questions are already secondary.

CPU. If the priority is long autonomous work, the low-voltage model. When performance is important, aim at full-fledged processors from Intel Core i3. Approximate frequency - not less than 2 GHz. Also it is necessary to consider the number of cores, the optimal for today - 2.

Operative. Current laptop users require 4 GB of memory. For the start and normal operation of games it is desirable to have at least 8 GB.

HDD. Here you need to focus on the total volume, the presence of SSD or, at least, the possibility of its installation.

In some cases, you need a video card. Modern devices are equipped with two components: integrated (for simple tasks) and discrete (for executing resource-intensive operations). However, the presence of both video cards does not guarantee good game properties of the device.

Case for testing With the help of special programs it is possible to easily and simply test the performance of a laptop. First you need to run it and make sure that there are no errors in the BIOS.

Next will stick the flash drive with the programs and check:.

Screen for the presence of defective pixels;.

Degree of deterioration of the battery;.

Hard disk for the presence of "broken" clusters;.

Degree of heating of components and t.

Careful testing will determine whether it is worth buying a laptop. But if the knowledge and experience in these matters is not enough, it is better to immediately buy equipment in a trusted shop.
