How to identify that a newly bought notebook is not a prototype

First of all, see if the seal has been opened.

I was looking at whether the plastic packaging paper in this book had been removed.

There are also buttons, there is no dust on the computer interface, and there are traces of no plugging.

I'm looking at the touch screen for fingerprints.

It's best to bring a software to see how long the hard disk is used, this software is good hddlife, you can see the time and life that has been used.

BatteryMon can see how the battery is being used.

When you buy it, look at whether the machine has been unboxed, and look at the tape on the front and back!

There is also a look at the keyhole to see if there are traces of use, and half of the prototype is locked to prevent loss.

Carefully observe whether there is more dust in the gaps of the keyboard and the screen bezel, as well as the air outlets, it is impossible for the used machine fan not to rotate, as long as the fan is running, it will bring in dust.

Check the keyboard keycaps and mouse for signs of wear, if used for a while, it will inevitably leave oily marks on the surface.

Remove the battery and check the back of the machine covered by the battery for fingerprints, usually the back case of the laptop will be made of metal plating, and it will be a finger print when you touch it, and it is difficult to erase it.

Look at the vents, the prototype has been used, and there will be dust in the vents.

You can go to the brand you bought to check the serial number of the product host!

What is the difference between a laptop sample machine and a ** machine? Can the sample machine be used? Knowledgeable.

Dear, hello, I am glad to answer for youA: The difference between the notebook sample machine and the ** machine is as follows: 1. The notebook prototype refers to the sample machine that has been placed on the counter for many days, and there is no difference between the ** machine, and the difference is that it has gone through the counter exhibition process, which has a direct impact on the life. For example, the display will be on for hundreds of hours, and even the battery will be charged and discharged multiple times, which directly affects the battery life.

2. Then the first machine is a finished model that has not been unpacked and packaged, and this model is very reliable. So it can't be compared with the prototype. The sample machine is used by everyone, and the non-sample machine generally refers to the new one, which is opened in front of you and installed in front of the battery.

The system may be factory pre-installed, or if it is not factory pre-installed, it must be installed in front of you. If you want to ask if you want to use the house to see the brand of the machine and the degree of use, I have a friend who asked someone to buy the sample machine, Lenovo, when I bought the prototype for two years, the configuration is also quite high, Warcraft can play anything, the price is not expensive, it has been used for more than two years, super envious So to say that the use of the residence or not to see if the machine is OK, as long as you look at it, don't change the important accessories inside!
