Is it harmful to periodically turn on / off the PC through the power button? For example, turn it on and turn it off after 5 seconds?

Question

Iron

I reflashed the bios, because I wanted a new firmware :) and at that moment the light was turned off, I turned the computer on / off 1000 times, because each time I tested whether the bios was working. , oz or other components will be harmed by this, because the light bulbs burn out from this.

Answer 1

Yes, there is harm. Even if you observe a minimum of 20 seconds, not 5

Answer 2

iron on / off to the light bulb. the only thing that does not like the frequent inclusion of a mechanic, for example in hdd. well, and a cheap power supply, in order to simplify, they sometimes clog x for transients when turned on.
Incandescent bulbs burn out due to the fact that an unheated filament has a low resistance and at the moment of switching on, a current exceeding the operating current flows through the bulb. LDS are also sensitive to inclusions because a highly heated filament is used to start electron emission.
there are no such elements in the computer - the computer can be hammered calmly.
I will only advise you to turn off the data storage systems (hdd ssd flash drives, etc.) from power for the duration of the swotting.

Answer 3

Depreciation of the power supply, BIOS chips (each power-up changes NVRAM, the cells of the chip have a resource of 10-100k rewrite cycles), and other components to a lesser extent. heating and cooling the chipset and the processor of the video card increase the chances of the chip falling off ...
and especially the wear and tear of your mood, I would never do such a useless thing as two hours in a row (1000 times 10 seconds per cycle) standing and poking at the computer shutdown button
