Please excuse me, as I do not have a link on this discovery, only that it has happened.
I had noted that at times a P.C. after a good amount of use, will at fist queue in the morning, by moving its mouse, will not rouse from sleep.
I had this happen and repeatedly move the mouse again and again and found that the system would not come on.
This sys stayed at asleep mode, so I thought that the hard-disk was going.
I shut the power down and then thruned the system completely back on. There was no response from the system and it still stayed at a sleep mode.
The button had turned from orange to blue-on and then I shut the power down once more.
I had stopped for a minute and use my intuition and at this point did not overreact.
I had heard the hard disk rapidly moving inside of the machine, so I had figured that if this was the case, then the system was processing allot of information and to give it time.
I let this be the course of action and low and behold, the system after I had switched the monitor on and off, all of a sudden came to life.
The entire system, for the space of about ten minutes, was tabulating something, but I did not check the task master, at the time, to see what this was.
It seems to me, that in some ways like humans who must rest, that certain styles of P.C.s might need a corresponding period of rest or deep sleep time.
This might be because the nature of the o.s. in a way, has a deeper subconscious and needs this period of sleep, to evolve certain deeper principles within the content of the O.S. and also ana-liptically speaking, within the semi core of structured memory.
In other words, the system is evolving.
