Apple computers can only go to the after sales inspection to check whether it is a refurbished machi

You can look up the serial number to see if the date you bought it was the activation date.

Hello, first, start with the appearance.

1. To tell if a MacBook is a refurbished machine, you can first start with its appearance. Start with the entire body, screen, keyboard, and see if there are scratches, appearance damage, etc.

2. In addition, you can also check the screws at the bottom of the notebook to see if there are any traces of twisting.

3. If the screw at the bottom has obvious traces of being twisted, it means that the machine must be refurbished. If there is no problem with the appearance of the notebook and there are no signs of twisting the screws, please read on.

2. Check the battery usage information.

1. Since MacBook Pro or Air will have a built-in battery, the battery will be charged and discharged frequently during use, and the battery has a forget-out function. We can start by looking at the number of battery usages, and from here we can see if the current laptop is refurbished. After entering the Mac system, please click the Apple icon in the upper left corner of the screen, and then click the "About this machine" option, 2, click the "System Report" button in the About This Machine information window, 3, and then click the "Power" option in the left column of the system report window, 4, and then see the "Number of Cycles" under the performance information in the battery information, here you can see that the number of cycles of my machine has been used for more than half a year is 152 times, 5, if it is a new MacBook notebook, Then the number of battery cycles should not exceed 10 times.

If there are too many cycles, it is used.

3. Check the serial number from Apple's official website.

1. In addition to the above two methods, we can also query through the serial number of the MacBook itself. Here it is recommended that you check the serial number of the machine at the bottom of the MacBook notebook, and find the serial serial number at the bottom, followed by the serial number.

2. Then please open the machine serial number query on Apple's official website, 3. Enter the serial number you see on the back of the machine, 4

4. Then you can view the maintenance and service warranty of the current machine, and there is an estimated expiration date here, which can be used to calculate its factory date. Subtract one year from this date, which is the factory date of this machine. This way you can know if the current machine is refurbished, if it is a lot different from your current date, it means that the machine is refurbished.

1. Look at the serial number: Most notebooks have the same serial number on the body and battery, if it is inconsistent, the battery is very likely to have been replaced, then this notebook is not recommended to consider no matter how cheap it is.

2. Look at the production date: If the production date reaches one year and is still on sale, then the computer is in a state of pressure and can no longer keep up with the speed of computer replacement. First take a closer look at the outside to see if there are traces of opening on the exterior and whether there are fingerprints on the fuselage.

3. Generally, in order to avoid suspicion, the merchant will not directly set it up for you, so you need to release the system and set up relevant information when you turn on it for the first time. If you get a computer that boots directly into the desktop, it is most likely not brand new.

4. Look at disk management, whether there is a backup partition or something, press and hold win+x key combination, disk management. That's these three partitions, this is the computer partitioning software, the new pre-installed system software will definitely have these partitions, if not, it is unlikely to be new.

Hello dear, I will answer for you this time, please be patient. <>

The steps to check if an Apple laptop is a refurbished machine are as follows:1Once you're on your Mac, tap the Apple icon in the top left corner of the screen, and then tap the "About This Mac" option.

2.Click the "System Report" button in the About Machine Information window. 3.

Next, click on the "Power" option in the left column of the system report window. 4.Then you can see the "number of cycles" under the efficiency information in the battery information, here you can see that the number of cycles of my more than half a year is 152 times, if it is a new MacBook notebook, then the number of battery cycles should not exceed 10 times.

If there are too many cycles, it is used. This solves the problem of checking whether an Apple laptop is a refurbished machine.

Method 1: Check the surface of the notebook, the current laptop has been frosted in many places such as near the keyboard, the surface of these places is often in contact with the human body, and it will become smooth and shiny after a long time, this place is generally difficult to renovate, which can be used as an important basis for our judgment.

Method 2: Check the fixing screws of the notebook, generally the old laptops acquired by merchants will have some problems, and the merchants must disassemble the notebook when they want to repair and refurbish the laptop, which is bound to leave obvious scratches on some screws, so if this trace is found on the screws, the laptop must have a problem.

Method 3: Check the surface of the display screen to observe whether there are small wear marks on it, because the surface is very thin and cannot be polished, so the wear on it is generally difficult to remove.
