How can the computer be turned on

When there is no power outage, when you have a computer monitor, when your computer is installed with the system, and the boot button on the host computer is still there, you can turn it on.

With the CPU, motherboard, memory, graphics card (integrated or discrete), the computer can be turned on. If you don't have a hard disk, you can use the boot disk to access the DOS or other systems. The friend upstairs may have misunderstood your question.

Take a hammer and say to the computer, turn it on!! If I don't open it, I'll smash you!! The computer turned on right away, huh.

Additional answer The smallest parts of the computer boot are the motherboard, memory, CPU, and graphics card, if there are no these parts, the buzzer on the motherboard will alarm, of course, it will not be able to start, of course, if it lacks other parts, your machine will not be able to enter the operating system and will not be able to operate.

1. Plug in the power switch of the chassis and monitor.

2. Connect the keyboard, mouse, and monitor cable normally.

3. Press the "Power" button on the front version of the case.

It's time to turn it on, doubt me, hehe.

Install the operating system.

Turn on the power and manually press the power button!

Operate in a temperature-friendly environment!

It cannot be operated in a temperature and bottom environment!

Power on without hard disk and light zone can be turned on, I used to use the soft area to start, hehe.

My friend above was right.

Turn off the lights, put the computer in the room**, light a candle and dance around it, and say "open sesame seeds" in your mouth, and you're good to go.

With the operating system installed, wouldn't it be enough to have electricity?

The last time I told someone to double-click on my computer, and it turned out to be a smash on his computer, I said how is that possible? He said, didn't you tell me to "hit", my first hit was just a crack, since you said you want to double-click, then I'll hit again......

Go to the south wall, you. No way.

The specific steps to turn on the computer are as follows:

The materials we need to prepare are: computers.

1. First of all, we open the lid of the notebook that needs to be turned on and show the keyboard.

2. Then we find the boot button in the upper left corner of the keyboard, which is on the top of the "ESC" key, as shown below

3. Then we press this boot button, and the computer will turn on.

The laptop can be powered on and directly press the power switch. The panel of the notebook has a similar power button on it,This is the computer's start button,If you want to start the computer,Click the button directly to complete the boot,Take LenovoY400 as an example,The position of the button is shown in the figure,Different models of computers can find such a button on the panel。

Extended information: The maintenance of the laptop case needs to pay attention to the following points: 1 Cut off the power when cleaning When cleaning the laptop, it must be done in a shutdown state.

It is best to unplug the external power supply and network cable, and remove the laptop battery before cleaning. 2 Choose a professional tool to clean the screenUse a cloth that specially wipes the LCD screen, which can not only remove dust, but also have the functions of preventing static electricity, disinfection and sterilization. 3 Cleaning of common parts For the cleaning of common parts such as keyboards and pointing boards, you can use a soft, slightly damp rag to gently wipe it, and then wipe it clean with a dry rag.

Gaps in the keyboard can be cleaned with a vacuum cleaner fitted with a small soft mouth. 4 Air outlet cleaning Choose a soft-bristled brush to clean the dust on the air outlet to avoid excessive dust accumulation at the air outlet and make the internal temperature of the laptop too high. 5 Regular cleaning Laptops will accumulate a lot of dust after a period of use, and regular cleaning can ensure that the laptop can complete the user's daily work and study in a stable state.

Moreover, users should maintain a good mindset when using their laptops. Follow the methods introduced above, and I believe that your laptop will definitely be able to prolong its life.

Before you turn it on, you need to do some preparation work on your computer. First of all, check that the power supply of the computer is connected well and that the power plug is plugged in tightly. Second, check if the monitor, keyboard, mouse, and other devices are connected normally.

Finally, check whether the hardware inside the computer is securely installed, such as memory modules, hard drives, etc.

2.Press the power button.

6.Use a computer.

When you're ready, press the power button on your computer. At this point, the circuits in the main computer start to work, and the power supply starts to supply.

The above are the steps to turn on the computer. It should be noted that during the use of the computer, it is necessary to pay attention to the protection of the computer to avoid problems such as hardware failure and virus attacks. At the same time, it is also necessary to back up important data in time to avoid data loss.

After the computer is turned on, a series of self-test processes will be carried out to check whether the hardware is normal. First of all, the computer will perform a BIOS self-test to check whether the hardware is normal. If there is a hardware failure, the computer will sound an alarm at this time.

Next, the computer will perform a hardware initialization to initialize the hardware device into a usable state.

Computer Shutdown Steps:

1. Ordinary and confident: start menu shutdown. The most common way is to call up the start menu - power options - shutdown through Windows, this step is to tell the computer to shut down, and the computer will perform a series of save and shutdown actions to shut down.

This method is very common, and many users use it, but they say that it is confident because they know that it will not lose any files and will not damage the hardware.

2. Simple and fast: shortcut key to power off. Alt+F4 is a commonly used shortcut to close, when you are running an application, use Alt+F4 to close its page, and when you are on the desktop, Alt+F4 can play a role in shutting down, the advantage is that it is convenient and fast, this method performs the same normal shutdown operation as the shutdown in the start menu, and will not damage files and hardware.

3. Rare but safe: the power button is turned off. We know that the power button on the console is turned on, but there are some users who don't know what it does as well.

Just like powering on, as long as you press the power button, the computer will perform a normal shutdown operation. Similarly, power button shutdown performs a regular shutdown operation and has no impact on files or hardware.
