What key is cold start for the computer to start cold

Cold boot. 1. The way to turn on the power to start the computer is called cold start.

2. Introduce "self-inspection".

3. The specific operation steps are as follows:

Power-up, self-test, boot operating system.

Warm boot. 1. Hot start refers to rebooting the operating system through the keyboard when the computer is already turned on.

It is generally used only when the machine crashes.

2. Method: Press and hold "CTRL" and "Alt" with your left hand and do not let go, press "DEL" with your right hand, and then release at the same time.

3. Hardware self-test is not performed for hot start.

Reset initiation. 1. Reset start refers to pressing the reset button on the panel of the main chassis to restart when the computer is already turned on.

2. Generally, it is used when the running state of the computer is abnormal and the hot start is invalid.

The boot is a cold start. A reboot is a hot start.

The computer is only started when it is not powered on, because the machine is cold at this time, so it is vividly said to be a cold start, and with the ctri+alt+delete key reset key and select the start menu shutdown (choose to shut down or log out or restart) Reboot belongs to the reboot of a live computer, so it is called a hot start.

There are several types of computer startups:

1. Cold start: Directly press the power or reset button to restart is called cold start.

2. Hot start: Press the three keys of Ctrl+Alt+Del on the keyboard to restart, which is hot start;

Cold start, a way to boot a computer. It is to cut off the power of the computer, restart, once the cold start, all the memory is lost, from the first detection of the hardware, into the CMOS, and then according to the boot of the operating system. Generally, press the power button on the chassis to start.

There are two ways to boot a computer, one is cold boot and the other is hot boot. Cold start is power-on start, turn on the power to start the computer.; A hot boot is a reboot of your computer without interruption of power.

The difference between hot start and cold start is that at the beginning, hot start is directly re-tested by BIOS in the case of computer use, and cold start requires us to turn on the power supply and have a stable voltage process.

The steps for a cold start are:

1. Turn on the power in the room;

2. Turn on the power of UPS;

3. Press the power button on the computer case;

4. The computer is booted up.

The steps for a cold boot on your computer are as follows:

Turn off the power: When the computer is powered off, turn off the power button or unplug the power cord.

Plug in the power supply: Plug the power plug into the power outlet behind the computer to provide power to the computer.

Power on: Press the power button on your computer's console to start your computer.

Self-test: After the computer is started, it will automatically perform a self-test to check whether the hardware device is working normally.

Enter the operating system: If the self-test passes, the computer will enter the operating system and start loading applications and system files.

Complete Boot: Once the operating system finishes booting, the user can access various features of the computer.

It is important to note that a cold boot takes longer to complete the boot process than a hot boot because the computer requires multiple steps such as self-testing and loading the operating system.

Starting a computer in a shutdown state is called a cold start.

In general, in addition to using it when starting up, try not to use it as much as possible, and if you often use it at every turn, the computer is prone to problems. ）

Hot start: It is used when the power is on.

1 Start Shutdown Restart OK ;

2 (alt+ctrl+delete) press all three together to restart the computer;

There is no problem with starting the computer with a hot start);

The difference is that one is bad (cold) and the other is good (hot);

Hot start is Li Mu restarting the computer without interrupting the power supply, and the cold start is powering on and starting the computer with the power on.

The difference is: first understand the process of computer booting The simple thing is, after the computer is powered on, after the voltage is stable, the BIOS program of the motherboard will begin to detect each hardware device of the computer (power-on self-test), and if there is no problem after the detection, it will be handed over to the system system and start to boot to the system, and we can see the picture of the system starting. All the way to the boot process of the entire computer from hardware to software.

The difference between hot start and cold start is that at the beginning, hot start is directly re-tested by BIOS in the case of computer use, and cold Qiye scattering requires us to turn on the power supply and have a process of voltage stabilization.

A cold start of a computer is the process of booting up a computer from a completely shut down state. During a cold boot, the computer needs to perform a self-test and load all the necessary system files and programs in order to run the operating system and other applications properly.

What does cold start mean? When the car starts coldly or starts at a relatively low temperature, there will be engine shake, high idle speed, gearbox frustration, brake noise, etc., and it will be accompanied by a large inadequate gasoline odor and black smoke, and the bearing of the steering machine should not be small, especially if you are in a hurry to turn on the air conditioner, the compressor will also be very noisy, but it will be fine after a while, do not rush to hang the gear, otherwise it will increase the burden of the relevant core components. Because when you start cold, your car's engine oil, transmission oil, brake fluid and other types of oil and water are not hot, and the water temperature is not up, and the whole car is cold, just like when you get up in the morning, the body hair shaft is a reason, and the speed of the hot car is below 1000, and all kinds of lubricating oil are warmed up.

The so-called "cold start" has two meanings, one is that the engine is started when the engine is cold; One is to start the engine when the ambient temperature is low when the weather is cold. Hello, cold start is to start when the water temperature of the engine is low, generally refers to a long time after stopping and then starting, like the next day after a night at night is the engine cold start refers to the engine has been shut down for a period of time since the last shutdown, and its internal temperature is consistent with the ambient temperature to start starting. Corresponding to this is the hot start of the engine, which means that the engine is started shortly after the last shutdown time and there is still a high residual temperature inside it.

It is more difficult to start an engine cold than a hot one, especially when the ambient temperature is very low and the fuel is diesel. This is because the internal temperature of the engine is too low during cold starts, and the fuel is not easily vaporized. In addition, the lubricating oil inside the engine may be destroyed in a solidified or sedimented state during cold start, resulting in poor lubrication of individual parts.

Therefore, after the cold start of the engine, it is necessary to run at low speed for a period of time, so that the internal temperature gradually rises, the fuel vaporization is very stable, and the parts are well lubricated, and then the load is added. The temperature of the water tank is the same as the outside temperature, at this time, the car is considered to be cold start, at this time the oil needs to heat up quickly, so the speed will be high when the cold start, and then slowly drop @2019
