How to identify refurbished computers?

1. How to identify refurbished computers?

Method 1, simple and crude - look at

1. Look at the serial number: Most laptops have the same serial number on the body and battery. If they are inconsistent, it means that the battery has most likely been replaced, so this laptop does not matter. No matter how cheap the price is, I suggest you not consider it.

2. Look at the production date: If the production date is one year old and it is still on sale, then the computer is in a state of being sold out and can no longer keep up with the replacement speed of computers.

This method is very simple. First, carefully observe the outside to see if there are any traces of being opened and whether there are fingerprints on the body.

If there are fingerprints, you need to check the computer carefully.

Generally, new phones will have a white dustproof paper on the keyboard layer.

Method 2, System Activation Page

Generally, for new computers, in order to avoid suspicion, the merchant will not set it up directly for you, so when you turn it on for the first time, you need to release the system and set relevant information yourself.

1. If the computer you get is turned on directly and enters the desktop.

2. Congratulations, it’s probably not a brand new phone.

3. Of course, unless you ask someone to help you fix the computer when you buy it, it doesn’t count.

Method 3, Disk Management

Check the disk management to see if there are backup partitions and the like.

1. Press and hold the WIN+X key combination, Disk Management;

2. That is these three partitions, this is the computer partition software.

New pre-installed system software must have these partitions.

If not, it means there is something wrong with the computer~

PS: The above is a super simple way to check your computer. If you want to see if your computer is brand new.

Check the hard drive usage time (common to desktops and laptops):

Whether the computer has been repackaged or refurbished, the appearance can be faked. But it is not that easy to fake the usage time of the hard disk. Therefore, if you have the opportunity, you can test the usage time of the hard disk at the place where you buy the computer. If you do not have the conditions, you can also test it yourself after you get it at home. If you find that the hard drive has been used for too long (perhaps hundreds or thousands of hours), it is very likely that you have bought a refurbished machine and you need to return or replace it immediately.

Method 4, Master Lu

Master Lu is also a software commonly used by people. It can still identify the configuration of your computer to a certain extent. You can take a look at this.

1. Take a look at your hard drive power-on information

Generally, if it shows that it has been used for more than 30 hours, 90% of them are refurbished or second-hand machines.

2. Check the battery loss.

Normal loss of a new machine should be around 5%. This is a good reference. It mainly depends on the power-on time of the hard drive.
