Hello, is your home computer a brand machine or a self-assembled machine? If it is a brand machine, some desktop notebooks can be restored to the factory through the one-click restore button when leaving the factory. The brand machine and assembly machine that leave the factory without the system are purchased to see if the system backup has been made.

If there is a backup. It is possible to restore the system with one click of restore. If you haven't made a backup, you'll have to reinstall the operating system.

In fact, if it is not a brand machine, it is recommended to install the system directly. In case of poisoning, the backup is not immune.

There are two concepts for a factory reset of a computer system:

1. Restore the computer to the state before activation, in this case, the user can not do it, the computer is irreversible, and the computer needs to be returned to the original factory for operation.

2. Restore the system to the state before the backup. In this case, the first condition is that a backup has been made.

1. For the system that has been backed up by the user, the user can continue to use the backup and restore tool to restore.

2. For the manufacturer's backup, such as Lenovo computer, you can restore it according to the instructions, or you can go to Lenovo's after-sales service to restore the system.

There is no way to restore the computer to factory settings, only to reinstall the system.

There are some laptops that come with a one-click restore function, and desktop computers need to install relevant recovery software to do so.

Only computers with a pre-installed recovery system and support shortcut boot recovery can restore the system. You can let the technician do a one-click restore after finishing the system.

There is no factory reset on the computer,This button or part of the computer of Lenovo will have a key to rescue,If there is this function on your computer,You can use it,Pay attention to saving files。

Method 1: Some notebooks have a one-click reset button, which is the key next to the boot button. With the system can you use this one-click restore,It's useless if you don't press it.,It's just a boot.。 Recovery, of course, is to restore to the state when it left the factory, just the C drive, nothing else.

Method 2: When the computer is turned on, press the "F2" button to enter the BIOS; 

Press"alt+f"The original CMOS settings can be restored.

Some computers are pressed F9

Those are the two options:

Award BIOS: Load Standard Defaults refers to the values set at the factory when loading the CMOS of the motherboard.

AMI BIOS: Load BIOS Setup Defaults refers to loading the motherboard CMOS

The value set at the factory.

BIOS factory default.

Method 3: Power on, the del key enters the BIOS settings, find load standard defaults or load BIOS setup defaults on the BIOS main menu (the English names of the two BIOS modules are slightly different), move the cursor to this menu with the cross arrow keys next to the keypad, press enter, select, and the BIOS settings will be restored to factory settings.

Knowing that you mean to restore to the state when you first bought the computer, if the computer has a restore point and it is established at this time, then it can be restored with a one-click restore. It's just that there are exceptions to everything, presumably if you make up your mind to restore factory settings, the system is already rotten, stuck or even crashed, and the files saved to restore points may also have the possibility of being damaged, so whether it can be successfully recovered is not absolute, and there is a certain risk; So instead of that, it's better to reinstall the system.
