What questions should I ask when buying a second-hand switch? How to check the machine?

This is the seventh year since the release of Switch. Many people choose a more favorable second mobile phone to buy, but they are afraid of buying a bad switch. Next, I will answer what questions need to be asked before buying a second-hand switch and how to accept it after getting it.

I. Pre-purchase issues

At present, the popular channels for buying second-hand switch are idle fish or transfer platforms, while the less popular ones are Baidu Post Bar or offline second-hand transactions of various communities/groups.

If you are trading around idle fish or platforms, you must ask clear questions before buying.

For example, the common defects of switch are rocker drift, screen bending and handle failure. If you don't ask clearly before buying, you can ask the seller to give you 48 hours for inspection. Usually, if there are serious problems, you can try it out soon. Be sure to confirm the receipt after inspection.

If it is a group friend/bar friend transaction found in the community or post bar, it is generally recommended to choose a secured trading platform, such as idle fish/transfer. As mentioned above, the receipt can only be confirmed after verification.

2. Manual inspection machine

Switch is divided into four versions, the first generation, the battery life version, the battery life portable version and the oled version. Among them, the first generation is the farthest from now, and the last three generations are still on sale, but the places that need attention are similar. Next, I will talk about the key areas that need acceptance.

1.sn code

Personally, I suggest choosing a second-hand switch. It is best to choose the version with the box. After you get it, you can verify whether the three codes are combined into one. The first password is on the lining of the box. You can see it when you open it.

The second code is on the lower side of the fuselage.

The third code needs to be opened to be seen.

If the non-Chinese version of the packaging box and the last two codes are incorrect, it has little relationship, which may be caused by sub-packaging during transportation, but if it is Chinese, you need to pay attention to whether it is an assembly machine. Verification of the rear fuselage and the inside of the machine is more important. If not, the machine may be refurbished or overhauled, resulting in inconsistent coding.

2. Screen

The screen is the most intuitive thing to see, so I put the screen first. After booting, you can open the pure white interface of the setting interface to see if there are any bad places, and you can also see if the surrounding black edges are skewed. The Oled version can open the solid color theme and observe whether there is a screen burning phenomenon.

deal with

Nintendo's joystick design is a bit problematic and not very durable, so this is also the focus of the investigation. It is recommended to use the game "Tears of the Kingdom of the legend of zelda" for testing, because this game uses all the functions of the switch, and the rocker and keys can be tested for looseness. At the same time, test whether the somatosensory operation of the handle is damaged.

5. Durability/battery loss

As a combination of handheld and host, battery life and battery loss are also very important test points. The normal battery life of the first version should be 2.5~6 hours, the battery life version should be 4.5~9 hours, the battery life of the portable version should be 3~7 hours, and the oled version should be 5~ 10 hour. The endurance performance of different games is different. But if each version can't even reach the minimum battery life, it can be considered that the battery has been damaged.

6. Network function test

Because of the prevalence of various purchasing or credit card shopping, many unscrupulous online sellers use black cards or black substitutes, which leads to the emergence of black machines, commonly known as ban machines. You can open a Nintendo store after you get it. If you can see the price normally, it means that you are not banned. If you can't see the price, you can confirm that it has been banned by 100%.
