Cold start in what situations to use

A cold boot is a power-on boot when the computer is not powered on, and it does check the hardware settings when it starts.

Resetting the boot is to restart the computer by pressing the reset button on the main unit, and there is really no need to turn the power on and off again.

Hot boot is to restart the computer by pressing the hot boot key combination on the keyboard (generally press CTRL+ALT+del on PC).

Because a hot boot skips some hardware check steps, a hot boot boots the computer faster than a cold boot.

Another difference is that cold boot and reset boot will erase the computer's memory data, while hot boot will not erase the computer's memory. So sometimes to get rid of viruses in memory, you have to start with a cold boot or a reset, not a hot boot.

After reading these, you should understand what kind of cold start is.

It is used when it is not possible to use an input device (such as a mouse, keyboard, etc.) to operate the computer. Such as: freeze, blue screen, etc.

If Ctrl+Alt+Del startup cannot be completed, select Cold Start, and the priority of startup is as follows

1.Normal shutdown (recommended).

Start (1 could not be completed).

3.Press the hot start button on the main unit (1,2 cannot be completed).

4. Press and hold the switch button of the host for 5 seconds (1,2,3 cannot be completed) 5, and power off (1,2,3,4 cannot be completed).

Nothing is reflected.

Cold start means that the engine has been turned off for a period of time, the temperature has been ** below the normal working temperature, and the oil has been reflowed, at this time the start is a cold start, so it may be a bit general, with data to explain to you, two hours of ignition, the engine temperature is lower than 40 degrees, at this time in the start is a cold start.

Cold start hurts the car more, according to the data, the engine more than 80 wear is in the cold start, cold start due to the low temperature, gasoline is not easy to burn resulting in vehicle start difficulty, followed by the oil to cover the engine everywhere, it takes a certain amount of time, at this time the engine is running without lubrication, the machinery rubs against each other will definitely make abnormal noise.

After a long time of parking, starting the car when the engine temperature is low is called a cold start.

The car has been driving for a while, and the water temperature has risen. At this time, do a short stop and then start it is called hot start.

In the case of cold start, you can drive normally at low speed and low gear for about 5 kilometers. Some people say that the water temperature is high at idle speed and then walk, I think it is easy to cause water accumulation and rust in the exhaust pipe, so it is recommended that the landlord drive at low speed and low gear after cold start.

A cold start is when the water temperature is lower than the normal engine temperature.

Usually the normal engine temperature is 86 degrees to 92 degrees.

Pay attention to buy some engine oil in winter, see how the 4S store recommends, you can buy it from them, or you can look at the model and buy it outside.

In winter, pay attention to keep the throttle clean, warm up the car for a few minutes, and then drive after the temperature rises.

Don't look too precious on the car, run at least a few times a month at high speed, engine speed 2500-3500 rpm is the best,

Cold start refers to the car in the case of direct start without preheating, mostly refers to the cold areas in the north, driving without preheating in the case of injury to the car is like running long distance without people doing warm-up exercises, it is easy to be injured, for the car, just start the oil has not lubricated the various parts of the engine, especially the crankshaft and crankshaft bearings, it is easy to strain, the driving capacity of the car will also decrease, and the service life of the engine will also be shortened. The best way to protect the engine is to preheat it in advance, run it for 5 to 10 minutes when the engine is not loaded, and the diesel engine will take 15 to 20 minutes, and the water temperature will be kept between 60 and 80 degrees, which is the optimal temperature.

You think it's a computer Hot and cold start Hehe When the car starts, the main reason is that the oil has not been pumped up, so the wear and tear on the engine is the greatest, but there is no good way to avoid it, what can be done is to wait for 2-3 minutes after the car is hit and then start After the temperature is normal, it is running.

It is best to warm up for 2 minutes before starting.

The amount of fuel injected is different:Cold start thickening fuel injection, hot car start normal fuel injection.

The startup speed is different:Generally, the car has traveled a certain mileage in the hot car state, so the engine and gearbox have a certain temperature, and the lubricating oil is fully lubricated in place. So the starting resistance is very small.

The lubricating oil is not in place during the cold start, and the starting resistance will be greater due to the low temperature and poor fluidity of the lubricating oil. Especially in winter, the colder the temperature, the more difficult it is to start cold, and the longer it takes.

Cold start considerations.

Cars that have been parked for a long time cannot be started, especially those that have been used for a long time, and often encounter difficulties in starting in winter. The difficulty in starting the car is generally caused by the lack of battery power, so remember to turn off the CD player, heater and lighting when turning off the engine for a long time to prevent power consumption.

When the weather turns cold, you should go to the 4S shop or repair shop in time to maintain and check the vehicle battery, if the measured voltage value is greater than 12V, it means that the battery is normal. If the voltage value is less than 12V, it means that the battery is already in a state of insufficient power. If it is lower, it means that it is not far from being scrapped, and it is best to replace it as soon as possible.

The difference between cold start and hot start is that it starts when one is turned on and when it is turned off.

A hot start is a reboot of the system while the computer is still powered on, and a hot start is also a software reset. However, a hot boot cleans up the volatile system memory and reloads the operating system.

A cold boot is a boot of the system when the system is powered off, a cold boot resets the hardware, it checks the hardware, and reloads the operating system.

When the computer is running in the DOS state, the computer will restart when you press the "Ctrl+Alt+Delete" key combination on the keyboard at the same time, and then let go at the same time.

PC hot boot has a high boot speed, and it eliminates the need for some systems to self-test.

Hello! Cold start refers to the car in the case of direct start without preheating, driving without preheating, for the car, just start the oil has not lubricated the various parts of the engine, especially the crankshaft and crankshaft bearings, it is easy to strain, the driving capacity of the car will also decrease, and it will also shorten the service life of the engine. The best way to protect the engine is to warm it up in advance, run it for 5 to 10 minutes without load on the engine, and 15 to 20 minutes for the diesel engine, and keep the water temperature between 60 and 80 degrees, which is the optimal temperature.

What does it mean to have a cold start in a car.

A cold-start engine usually doesn't start the car for a long time (e.g. after 4 hours of parking or after parking at night). After the car stops for 4 hours, the oil will fall back to the oil pan due to gravity. At this time, if the engine is started again, the oil cannot run quickly to reach all parts of the engine, resulting in dry friction wear, which is commonly known as cold start.

This wear accounts for more than 80% of engine wear. The car is not afraid to drive, but it is afraid of parking for too long. Of course, cold starts can be solved with engine protectors.

Such as graphene protectant. It is a 24-hour uninterrupted pure physical protection for the engine, and the graphene protective film formed on the surface of the engine is solid protection, which can effectively repair the wear and tear of the engine surface and enhance the engine power. Hope it helps.
