I tought it was getting too hot or something but the temp is 47 c AVG. i ran Dell diagnostic tool and everything Passed.
Any suggestions ???
That would indicate that nothing's using the CPU. Weird.
So if I'm understanding you correctly, when you go into task manager, under the "performance" tab, you see the CPU usage pegged at 100% but when you go into the "processes" tab, nothing is showing CPU activity but the System Idle process?
For instance, I attached a screenshot of my task manager. The highlighted tab - CPU - shows what percentage of the CPU each process is using. And at the bottom, it shows the percentage of the CPU that all my current programs are using (in my example, it's 6%).
I don't understand how it's possible for your total CPU usage to be maxed out but Task Manager saying nothing's using it.
Sorry for bumping an old post, but I've been having the same problem with my E1705 for awhile, 100% CPU utilization w/ fans maxing out and then the computer starts to lag, even when i type. This happens with a fresh install of windows vista, windows xp and windows 7 and there is no viruses. I've replaced my fan as well on my videocard, last time i had it apart, as it seemed that the bearings were stiff, probably from the fans being maxed out. I noticed before and still notice with the new fan that if i don't blow into the GPU vent, the fan does not spin up to its rpms as its supposed to. IT'll show fluctuating RPMS in i8kfangui but when u look at that fan, its visably not spinning until you blow on it and get it to spin on its own. This problem doesnt remedy itself unless I reboot the computer. Any ideas?
i had e1705/x1400.
Only thing I have changed is the Hard drive, it now has one i got from newegg awhile back.
Here recently, as in less than two weeks, I installed a new GPU fan, and put Arctic silver 5 on both the CPU and the GPU just to make sure. I was also thinking, I did do a bios update, not too soon before all this happened, to A10. Sometimes mashing the 'apply' button a half dozen times in manual fan mode on 18kfangui finally gets the gpu fan to spin, otherwise I do have to blow on it. When i stick a tooth pick in the vent, the fan is freely spinning.
Cant believe it, as soon as i rolled back the bios to A09, problem solved. Does Dell do this to sabotage laptops so you have to buy a new one? I seen a lot of people with, what i think, is the same issue. Regardless, having a laptop that doesnt hit 70+ degrees celcius for the win! I8kfangui seems to be controlling things again as well.
I forgot to mention. I had originally worked around this problem by disabling the CPU speed stepping option in the BIOS. After upgrading to A10 I was able to turn this feature on as it now works properly. I thought I had a virus as well, but apparently it was a problem with the BIOS interacting with a notoriously buggy feature of the Intel Centrino. If you don't use your laptop on battery a lot you can just keep speed stepping disabled and it will always run at the higher speed.
