Box: The inspection of the box includes three parts, one is to see if the appearance is damaged by bumps, and the other is to look at the appearance color. All red is the battery life version and half is the white version. The third is to check whether the cardboard in the middle of the box has string codes, which is also the key to the follow-up inspection of the three codes.
After starting up, query the Switch3 code in the chassis, host and machine body;
Color, there is no specific standard, completely depends on the player who buys the host;
Base: The base is relatively strong, and the core part is actually very small, so it is generally not easy to be damaged. It mainly checks the appearance and slot, and then it can be connected to the monitor to test its function.
Flat panel: the flat panel is the core of the switch, and it is also the most inspected part, which is divided into six aspects: appearance, card slot, start-up charging, three-in-one code, keys and Eshop.
First, the appearance. Whether to stick a protective film, whether to stick a pain piece, whether to modify it, whether the screw has white marks of being screwed, whether to bump, whether to scratch, whether to bend, whether to have a lot of oil stains on the back, and whether to have a lot of dust or dander in the sound hole below the flat plate.
The switch screen is a plastic screen, which is resistant to falling and easy to scratch. You'd better stick a screen protective film.
Generally speaking, in the second-hand market, machines will be marked as 99 new, 95 new, 9 new and so on. This criterion is too dependent on the seller's individual and has no reference value. You can judge the old and new degree by yourself from the aspects of purchase time, use time and backtracking.
If there are white marks on the screw, it is likely to be disassembled or modified. If there are painful stickers, it is difficult to judge the old and new degree of the machine, which is also something to pay attention to when purchasing.
Two. Card slot. Switch always has two slots, one is located on the flat plate, which is a slot, and the other is located behind the rear bracket, which is a TF slot. The inspection of the card slot is mainly to check the appearance, whether there is damage, and whether there is a lot of dust or dander. If possible, you can use a cassette or TF card to check whether the card slot can work normally.
Ⅲ. Start charging. Press and hold the power button to turn on the machine, and observe whether the machine is turned on normally. When the power cord is connected to the lower Type-C port to charge the machine, the power display in the upper right corner of the host will change to charging state;
Ⅳ. Sequence code. The three-code combination of the switch refers to the serial number on the cardboard in the middle of the chassis, and the serial number on the lower side of the flat is the same as the serial number of the host in the serial number information of Settings-Host-Machine.
At the same time, the "serial number information" also includes the serial number information of the battery and the left and right Joy-Con. The serial number of Joy-Con should be the same as that of the plastic sleeve containing Joy-Con. In addition, it can be inquired whether the serial number of the host can be cracked through various inquiry channels.
In addition, the bottom HAC-001/HAC-001(-01) behind the host can also be used to judge the normal version/endurance version;
ⅴ. Press the key. The buttons of the host mainly include the power button and the volume button, which can be pressed in turn to check whether the function is normal;
ⅵ. Electronic store. Whether you can enter Eshop is the key to check whether the machine is banned. If the machine has its own account, you can use this account to log in to Eshop directly. If there is no account on the machine, you can register an account and log in to Eshop. If the login is normal, the machine is normal.
Joy-con: Joy-con is estimated to come from the naming method of Japanese loanwords, which is formed by splicing the first three sounds of "Joy Control", meaning joy controller.
Joy-Con is also the testing center of second-hand switch, which is divided into three aspects: key, remote control lever and slide rail, among which the remote control lever is the most important. Because of the old man's workmanship and the extensive use of the left joystick, the drift of the remote control lever is a * * * problem with time.
If you don't have a game at hand, you can go to the settings of the host computer-handle and sensor-to adjust the remote control lever and check whether the remote control lever drifts. If you have a game at hand, enter the game, move in all directions, press each button, and play for about ten minutes to know the situation of Joy-Con.
When the remote control lever drifts, it will not return to the cross icon in the correction of the remote control lever, and it will not stop normally when it moves in a specific direction in the game.
