eli5: Does it matter to a computer how long it’s powered off for? Is one micro-second as good as 5 minutes? If not, why and how long is optimal for it to be powered off for?

Question

That is the question. I almost never turn off the computer, but sometimes flick it off for just a second or two. Is this bad for it? Does it need rest? Thanks!

Answer 1

Yes.

If too short (probably a second or few), there may be some issues with power (residual charge in capacitors, etc). Generally not an issue with modern PCs. If too long (a few years), the battery saving BIOS settings would run out (not necessarily an issue), also lubricants in all the fans would dry out causing extra power draw and overheating.

There are other issues that happen over time (i.e. capacitors drying out), but they do not necessarily care whether computer is on or off.
