Is it dangerous to power off the computer while it is off?

Question

Iron

There are two computers, the second one works very rarely, so the girl writes term papers, etc. .. Therefore, it is always turned off, but the power to it and the monitor goes through the outlet, is it dangerous to constantly turn off / turn on the outlet, thereby stopping powering the monitor and power supply? (NOT ON, but simply)

And if so often done? Let's say he took out the "plug" with the computer from the socket, turned on the charger for the phone, then back the plug with the computer back into the socket .. Does this affect the hardware?

Answer 1

No.
A long shutdown from the outlet can affect, because of this, the battery on the motherboard, which keeps the CMOS settings and the clock, gradually discharges. But it takes a couple of years without an outlet, so that it is at least somehow noticeable. In terms of wear and tear, in standby mode, both the computer and the monitor consume a little energy. In some cases, it may be noticeable if, for example, an external drive or a 4g modem is turned on via USB, and USB power is also supplied in the duty room. In older computers, this was configured with a jumper on the board, now in the BIOS. But sometimes it is not configured in any way, but as the developer wanted, he did it.

Answer 2

In the network, alternating voltage with a frequency of 50 Hz. (50 pulses per second).
That is, every second 50 times power is supplied and removed from your device. Therefore, you can safely remove and insert the power cord plug as much as you want.
Another question is that at the moment the plug contacts the socket, a surge of current occurs and if your device is NOT working properly, this surge can be critically large for those parts of the device that failed but continued to work in lighter modes.
That is: The inclusion itself is NOT dangerous. BUT turning on a faulty device causes an existing fault to manifest itself.

Answer 3

It doesn’t affect it at all, except that you gouge the socket in such a way, put a tee there already.
