Problem with processor, process called "System Idle" overloads CPU

[Forrr]

Hello, today I've turned computer on, and when Windows loaded, I saw that CPU load of my computer is 25-35 % and is caused by "System Idle process". Ok, I know that this process works when computer does nothing, but I've noticed one important thing - until this process wasn't working on my laptop, PC was working on batteries up to 5 hours, now, when this innormal process is working, time on batteries is 2h 50 min (max)... How I can turn off that stupid process?

P.S. I've already reinstalled Windows, only because of that problem, and I was happy only 3 days, today, this stupid process RETURNED...
P.S.S. I use Russian version of Windows.

I also uploaded two screenshots, where you can see that "system idle process" below, I've marked it (Screenshot nr.2)

its not a process. its the percentage the processor is idle. as in doing nothing. as in NOT using battery. 97-99% is where it should be when doing nothing. it should always show. it should always be high. the space above the green line is system idle process. under it and what's causing system load is everything else. if an actual process were at 97% the system load would be 97%

I don't know what stuff is titled in Russian, but in the process window click "options" and under "view" add in the "CPU time". then uncheck or check the box at they bottom of the process window that says show processes for all users and sort by CPU time to find anything that's actually causing load

That process is ALWAYS there. Windows 101 here, that "process" simply shows how much of your processor is NOT being utilized at that particular point in time.

If you were happy for 3 days and then it started acting up again, you probably installed something that has been slowing it down. Something you had installed on the machine before you reinstalled Windows. Check over your recently installed items and see what could be the problem.

Try downloading CCleaner, a free program that allows you to choose what programs will start on boot up, and you can clean registry problems to and much more. I had similar problems with load times and PC speed, but running this and sorting what I want to run on boot up cleared most of the problems. If I install a program/toolbar that refuses to be turned off when I try, then I remove that program/toolbar. Unless it's a system or other important item.
