CPU running at 100% on LG F1

OK, rereading this, I don't quite understand what is going on. Your fan speed should be based on your CPU temperature, not its frequency. If it is running full time, that means your processor is running hot. Can you download CoreTemp and run it. That will tell you the CPU utilization and temperatures.

The only way the CPU should be that hot is thar some process or the kernel is putting a high load on the system, or you are idle, but the heat sink/fan is not seated properly or working well.

"Wouldn't the CPU get hot as long as its stuck on 1,73, even if no processes is using it?"

Well it'll run a warmer than if it were clocked down to 1100 or something, but even at 1700, it wont be anywhere near as hot when the computer is idling as it would be if you were running prime95 or any other program that maxx3ed out the CPU.

But those "idle" temps are pretty high, but laptops almost all run hot these days . If you HAD been running prime95 for an hour it probably would have come close to or hit the max temp I'd bet.

Is that the program you are using to test the frequency? It may not be accurately telling you the actual frequency, just the BIOS setting. It's hard to tell sometimes... I use the "All CPU Meter" desktop gadget and I know that it does show the actual to the second CPU speed. Might try that one out. (Most Wanted Windows Gadgets - Windows Vista and Windows 7)

No, running at 1.73 won't overheat the CPU. I have one at 3.4 and its temp is 32-36 at idle. Try blowing out all of the vents and intakes on the laptop. Is it setting on your lap or a soft surface which may block airflow?

I believe that the responsibility for allowing/enabling the variable clock rates is up to the BIOS.

There may be some reason that the laptop manufacturer turn that off permanently, maybe some of the other hardware couldn't deal with it or the main board was unstable with a changing clock rate.

What would be interesting is to find out if someone else on the boards (or on the net anywhere) has the same exact model and if the clock down at idle feature works on theirs or not.

I can't think of anything else atm... Laptops can get locked down in weird ways :/ Though this very function is very laptop oriented to reduce heat and power usage...

The only thing I can think of now is to try to verify for sure that that laptop even supports it, and that may be a challenge. The manufacturers tech support is likely to be completely useless for something like that (though worth the futile try at least).

Finding someone somewhere on the net with the same exact notebook would be good, can see what theirs is doing compared to yours...
