How to tell if a laptop is refurbished?

The hard disk can be used for 34 hours to determine that it is a new machine, and the 34 hours of factory inspection and installation of the system can be accepted. As for the manufacturing time, he doesn't have to worry about it, because the display is not produced by Acer, and the production time of the computer is, to put it bluntly, the assembly time of the computer. Also, the software sometimes can't be accurate.

If you really don't feel at ease, go to Acer's official ** enter the serial number of the machine and check it.

You can use Master Lu to detect the hard disk information of the notebook, you can view the current hard disk usage time, if the number of uses and the use time is short, there is no problem, because the computer will be factory tested, generally within 30 hours, but if the use time is too long, it means that it is second-hand or refurbished.

It shouldn't be refurbished, you can go to the after-sales service to detect the use time of the hard disk, and the manufacturing time of the display has something to do with it.

1. Look at the serial number. Most departments should have the same serial number on the body and battery of the laptop, if the battery serial number is inconsistent with the serial number of the host, the battery is very likely to have been replaced; In addition, when purchasing foreign brand notebook products, whether the serial number of the fuselage is consistent with the battery and the outer packaging is a very important basis for overhauling whether the product is parallel imports.

2. Look at the anti-theft lock hole. If there is a blot, it means that the notebook anti-theft lock has been inserted, and it is very likely that a prototype has been made.

3. Look at the feet. If it is worn and dirty, it means that it has been used and the workbench on the production line is not so dirty.

4. Look at the cooling fan. If there is already a thin layer of dust on the fan blade, it means that it has been used for more than a week.

5. See the date of delivery. The original book that left the factory three months ago is still on the market, so you should pay attention. The sales of electronic products are updated very quickly, and it is impossible to let a book be pressed in the channel for so long.

6. Look at the keyboard. The keyboard of the new book is clean, but it doesn't shine. There will be dust in the gaps of the used keyboard, and the few keys that are commonly used will be polished.

Here are some common ways to tell if your PC is refurbished:

Appearance: A refurbished PC may have noticeable wear and tear, scratches, or other inconsistencies over a longer period of time than a new one.

Performance: You can use software to test the performance of your computer, such as your computer's power consumption, battery life, running speed, graphics card 3D image rendering quality, hard disk write and readout speed, and other indicators to evaluate your computer's performance.

Serial number: You can query the serial number record of the after-sales service station of the brand to which the computer belongs, and further verify whether it is shipped from the original factory or re-integrated, and understand the configuration and production batch corresponding to the serial number.

Configuration and additional functions: which original parts have been replaced and the specific replacement situation, such as memory Mashan bar, late mold hard disk, keyboard, etc. Normally, a large number of internal vulnerable parts such as power supplies and accelerators are replaced in a short period of time is also a signal.

Where to buy: Unless you get it from a regular merchant, there is a certain percentage of refurbished computers purchased on some second-hand trading platforms.

It should be noted that refurbishment does not mean bad, and after being repaired and replaced by technical professionals, it can also ensure that the quality of the ability basically meets the relevant standards. But at the same time, if the user does not know when buying but pays for the new computer, it is the problem. Therefore, it is recommended to understand and compare the market when purchasing, so as to obtain the highest price-to-price ratio of the product.

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 date of production: If the production date reaches one year and is still on sale, then the computer is in a state of pressure and can not keep up with the speed of computer replacement, so it is recommended not to buy.

3.Look at the appearance: This method is very simple, first carefully observe the outside, see if there are traces of the appearance of the opening, and whether the fuselage has fingerprints. If you have fingerprints, you need to check the computer carefully.

4.Check the use time of the hard disk (common to desktops and laptops): whether the computer has been repackaged, whether it is refurbished, and whether it can be faked from the appearance.

However, it is not so simple to cheat the use time of the hard disk, so if you have the opportunity, you can check the use time of the hard disk at the site of buying the computer; If there are no conditions, then you can also take it to your home and test it yourself.

If you find that the hard drive has been used for too long (maybe hundreds or thousands of hours), it is very likely that you have bought a refurbished phone and need to return or replace it in time.

5.Use the cmd command "systeminfo", which displays detailed configuration information about the computer and its operating system, including operating system configuration, security information, product IDs, and hardware attributes such as memory, disk space, network cards, and patch information.

Enter cmd and enter systeminfo after entering the win+r shortcut key

How to buy a notebook is not a refurbished machine nuclear pie, the specific methods are as follows:

1. Simple and crude: look.

Does this mean that it was used on March 24th?

The production date is March 21.

Dear, does this mean that it was used on March 24th? Yes, it will only be recorded after use.

I bought it on June 17th, so isn't this a new machine?

Nowadays, computers are a very fast replacement product, and many people will sell their computers and buy new ones, and these old computers are often refurbished and sold by merchants. How to check if your computer is refurbished? There are a few steps!

The most straightforward is to look directly at the serial number, generally the computer body will be pasted with the serial number, here if the serial number is inconsistent, it means that the computer may have been replaced with parts, such as batteries, motherboards, etc. Don't think about it.

Look at the production date, if the production date is still on sale after one year, it means that this computer is unsalable. Another simple way is to carefully look at the fuselage for signs of being opened or used, and whether there are fingerprints.

Judging from the system activation page, the first time a new computer enters the system, it needs to be set up according to the system guidance! If you turn on your computer and go straight to your desktop, there's a good chance there's something wrong with your computer.

**Master Lu, here is an important explanation, don't connect to the Internet when you buy a new computer, use a USB flash drive to import a Master Lu into it to install and test whether the hardware is intact. Take a look at how long your hard drive and battery last. Otherwise, once connected to the Internet, the computer will automatically activate the system, and the general merchants who have activated it will not give a return.

Unless it's a quality issue.

Open Master Lu to take a look at the information of the hard disk, and detect that if the hard disk is used for a long time, it may be a refurbished machine. In addition, depending on the battery loss, the normal new machine is generally about 5%.

The above are some of the ways to detect new machines!
