Don t know how to turn it on? How do I turn it on?

I don't know what the device is and don't understand how to turn it on? Like a computer or some other electrical device? Annoying electrical equipment has a power switch, and you must check whether the circuit is connected correctly before turning it on.

First of all, explain what device has the power on button--- computer, mobile phone, tablet or other device.

Check the power supply line connection switch first...

In this case, if it is useless to press the power button, then it may be a hardware problem, the power button is broken, if you press the power button to open it, you can't enter the system, then it is a system problem, so you must be clear about how it can't be turned on.

If you can't force it to turn on, please check whether the phone has power, there will be a charging indication when plugged in when the power is empty, it may not turn on immediately when it is just charged, please continue to charge for a period of time, and then try to turn it on.

Not all computers boot up by pressing the boot button, like the BIOS, you can actually set it to boot through the password.

Hello, the correct way to turn on the machine 1, first turn on the main power. It is to connect the total power supply between the host and the display. Generally, it is a socket strip, and the switch that turns on the socket strip is turned on.

2. Turn on the monitor first. This step is often misunderstood, and the first thing you need to do is turn on the monitor. This is good for the display.

3. Turn on the host again. Once you have turned on the monitor, you can press the start button of the console. This sequence cannot be reversed, otherwise it will damage the service life of the machine.

The correct way to shut down the computer 1. Close all programs. The first thing to do is to close all the programs that are open. It's better not to leave any of them.

So you don't forget to save the file. The shutdown speed will also be accelerated. 2. Turn off the computer.

After closing all programs, press "Start Shut down the computer" to shut down the computer. 3. Turn off the monitor. Once the computer display shutdown is complete and the monitor screen goes black, you can turn off the monitor.

Don't turn off the monitor first, so you won't be able to tell if the computer has turned off completely. 4. Turn off the power. Turn off the main power supply, i.e. the power supply on the plug strip as well.

The computer is now shut down. Remember to turn off the main power as well, this is also for the sake of the environment.

After pressing the power button, the motherboard is powered on, start the BIOS, perform a self-test, detect the internal and external devices, if there is a hard disk, the BIOS will hand over the control to the MBR of the hard disk, and the MBR will boot the system according to the information stored by itself.

Use the Volume Down key to move to the bottom of Power Off and press the Power Off button once.

When it shuts down, it can be turned on normally.

The main factors that the mobile phone cannot be turned on are the battery, mobile phone software, and hardware that will cause the failure to turn on. In general, we recommend that you perform the following steps:

1. Charge with wire for a period of time and try to turn it on.

2. Take out the SIM card and SD card at the same time, and then press the power button for more than 10 seconds to test whether it can be turned on.

3. If you can enter the boot interface, but your phone cannot enter the home page, please restart your phone to try. The operation steps are as follows: Press and hold the power button and the down volume button at the same time for more than 7 seconds to restart the device.

Note: Some models require you to press and hold the power button for 8-10 seconds to restart the phone).

If it still can't be turned on normally, there may be a problem with the system program or hardware, and it is recommended to send the phone to the nearest service center for testing.

This estimate is mostly due to a problem with the system or a problem with the battery and other hardware, so I have to take it for repair.
