Sorry about that plvera,
I posted with ps -ef, where you probably should be using similar to ps -aux.

Edit, There will be a cpu column

Dave,
Thanks for the suggestions but ps (or htop or top) did not really show what was eating up cpu time.

I think I figured out what's going on though. I noticed that space in the root directory kept decreasing. I searched and /usr/log had a large amount of data. In there, pm-powersave.log grows to be over 2G!!! I deleted that and root space came back to normal.

So I restarted the laptop and have the same problem with cpu being too high and this pm-powersave.log keeps getting bigger and bigger. My guess is that whatever is writing into it gives up in about 2 days and leaves behind a rather large file.

What can I do about this? My battery needs to be replaced. Not really sure if this is related to the battery or not.

thanks.

Try running with the battery removed maybe? I've done it before to trouble shoot laptop problems.

I also wonder if making your own powersave file will keep a new one being made a wrote to. Kinda like that keylogger thing reported back in Sept in /home.

Roky,

You're a genius!! Taking out the battery stopped the cpu use.

Eino, thanks for your suggestion. I'll try it to see if I can isolate the problem (other than replace the battery)

If you look at your logs, you may have one larger than normal from the system reporting the bad battery over, and over again..
