Constantly 1 cpu at full load, nothings running, no restarts helped. CPUs alternate as you can see in the image

Drains my battery! no application is taking up any CPU power and yet the chip runs at 100%.

Have you checked out your Activity Monitor to see what the culprit is? Truly strange though.

No sign of anything in activity monitor, there are barely any processes, and the three actively using CPU hover at 5 or less percent

i don't know if this would help, but have you tried repairing permissions? maybe it thinks it's supposed to be doing something? i have no technical basis, but permission are something I always check.

Make sure you are viewing ALL Processes in Activity Monitor. You may have a system task that is taking up the CPU time and are not seeing it by default.


Oh, nevermind. Just realized that your CPU chart is showing all green. That's user tasks.

Permissions didn't do anything, guess i'll just backup and re-image

Time for a clean install anyway, it's been all of FOUR MONTHS since i had leopard on :O

There should be anywhere from 20 to 50+ processes running (give or take) depending on what's running. If you only see a total of maybe 5 or 10 then check to make sure you're seeing all processes (as per Artoz's suggestion).

If a processor is failing usually it would go into a loop and be at 100% all the time.

I notice as well that when the bottom CPU drops off a little the top one kicks in and vice versa. I'd guess this would be an actual application process rather than defective hardware.

There are 60 processes running but i can only see the user processes, shouldnt be a problem since whatever's consuming the CPU time is listed as a user process anyway.

I doubt its a hardware issue but it could be, seeing as this problem only came up a few days after i collected my MBP from it's second vivisection at the apple store
