What happens if I accidentally unplug the computer while it s still on?

If your computer is better, that's fine. Try to be careful, though. Don't be careless every time, it will damage the hard drive.

If the computer is on standby, there is no problem. Because then the hard drive was turned off. If the computer is running and there are no big programs running, the problem is not very big.

If it is in the reading of the disk, especially in the transmission of data, etc., the damage is great. The small ones are boot scans, big data loss, bad sectors on the hard drive, and so on.

That is equivalent to illegal shutdown, of course, it has an impact, the motherboard is a digital integrated circuit, and long-term illegal shutdown will affect its service life. However, a small number of illegal shutdowns have little impact, so you can rest assured. However, after illegal shutdown, you must self-check when you turn on the machine, so that you can find the problem in time and solve it in time!

1 The game you're playing or the files you're working on are gone.

2 The hard drive is not broken, fortunately.

Oh my god, don't do this kind of thing that doesn't do any good to the hard drive.

Are you doing a brain teaser?

What if the plug is removed when the computer is on, and then the computer breaks? Even if you can't fix it, you can't fix it?

Yi generally does not damage the hardware, but parallel goods and refurbished goods are not included.

Generally, it will not have an effect, and may reduce the life of the machine, or cause damage to some devices.

Software: If you're lucky, it's a big deal to start the system automatically detect the disk, and then keep it as usual;

When the machine is turned on again, the system will automatically check and repair it automatically, so it is no big deal.

Every day the computer is turned off, the power plug is unplugged, and the computer does not have any adverse effects.

Conversely, unplugging the power supply after shutting down can also have certain benefits:

1. Protect the power supply of the computer.

If you don't unplug the power plug, the computer power supply will always be powered on, and some of its circuits and components will continue to work;

2. Protect the motherboard.

If you don't completely disconnect the power supply, there will be a standby voltage of 5V on the motherboard, and the standby circuit will also be working.

1. Turn on. The external equipment of the computer will produce a large current at the moment of power-on and power-off, and the large current will interfere with the start of the host, causing the host to fail to start or abnormal. Therefore, you should first power on external devices, such as monitors, audio, printers, scanners, etc., and then press the power switch on the host panel to power on the host, so as to avoid the host being impacted by high current.

2. Shut down. Contrary to powering on, turn off the host first, instead of pressing the power switch of the host to turn off the power switch like powering on, but click the lower left corner of the monitor with the mouse to "start" to turn off the host, and then turn off the external devices. Although the new computer has strong protection features, it is best to do what is said above.

When using the computer, you can't turn off the power directly, and you must shut it down according to the normal program to avoid the hardware in the host being destroyed by the impact of large current.

Within a day, you need to turn on and off the computer several times, generally do not need to unplug, a few days do not need or when there is thunder, you should unplug the network cable at any time to prevent lightning strikes. Even if it is not unplugged, its power consumption is limited and can be ignored. When thunder, it is useless to turn off the socket switch only, because the motherboard is most afraid of high-voltage induced current.

It also includes network cables, which also generate high-voltage induced electricity during lightning strikes, which can harm the motherboard and other hardware components.

Here's how to fix it:

1. You can clear your CMOS first, that is, there is a jumper on the motherboard is clear, you can find it, if you can't find it, you can take the battery on the motherboard round it and put it on it after a few minutes.

2. There is a problem with the power supply, it is very simple to solve this, you can find a good power supply to try it.

3. There may be a short circuit, and the simple solution is the method in 1 or let the maintenance personnel in computer technology help you look at it.

4. Capacitor burst is also possible, if you think you can do it yourself, you can try it, or find a friend, the computer can help, there are also three possible faults, one is the power supply problem, the second is the problem of the motherboard, and the third is the problem of the switch.
