The computer needs to be turned off without the power being disconnected

Is it a desktop or a laptop? If it's a desktop, I suggest verifying a problem: I've encountered a kind of fan is still rotating after shutting down to assist heat dissipation, if this is the case, it is recommended not to pull it out, and then say it after ten minutes, if it is not recommended that the total power supply on the plug-in board is turned off, because the current power grid makes you feel uneasy, the voltage instability is very serious, although the power supply part of the computer has a voltage stabilization design, but it is always limited, a while ago, the BenQ notebook of the classmate burned the motherboard when it was plugged in, so it must be turned off.

However, the switch should not be repeated, because the quality of the current power strip is uneven, and many of them may have strong power surges when they are turned on, so it is recommended not to pull them out if they need to be turned on frequently, and the risk is higher.

It depends on the specific situation, if you want to use it after a while after shutting it down, it is best not to disconnect, because there is a current pulse when the motherboard is connected to the power supply.

If it won't be used for a long time after shutting down, then it's best to disconnect the power supply to the power strip and the plug won't need to be unplugged. (The wiring board is often referred to as a multi-purpose plug, and there is a switch on the general wiring board.) )

It is very rare to unplug the plug, my personal habit is that after the computer is shut down normally, the main power is turned off, that is, all peripheral products including the computer such as audio or something will be turned off.

I'm off the host! Nothing else!

When you turn it on, the right power on is! Turn on the external device first and turn on the host! For example, monitors!

When you turn on the monitor, there will be a strong current shock (in the Internet café, you should feel that your machine will shake when others turn on the computer)! This will make the machine age faster.

It's the same with plugging and unplugging the power supply!

Common external devices: monitors, stereos, printers, scanners.

It is best to unplug it to avoid a short circuit in the motherboard.

Take Dell Inspiron 5000, win10 system as an example, the main reason for this situation:

1. There is a problem with the charging and discharging circuit of the laptop, which leads to the abnormal storage and power supply of the battery board. As a result, the computer shuts down after the power is off.

2. There is a problem with the charging socket of the notebook, which causes the computer to not be powered on, and at the same time, the battery of the computer is out of power, resulting in shutdown.

3. The notebook has been used for a long time, and the battery has abnormal storage due to incorrect use habits.

Therefore, when the laptop automatically shuts down after the power is off, please connect the power supply first, and right-click "My Computer" after turning it on, and then click "Device Manager" in the management interface to check whether the battery is deactivated;

Or right-click "Properties" in the main interface of your computer, select "Screen Saver", and then click "Power" to see if the settings are correct. If none of the above methods can solve the problem, it is recommended to send the computer to a professional maintenance store for repair in time.

The answer is for most models of computers at Dell.
