This is normal on some systems. Was it ever fast on any kernel version?
Comment 2 fernando.apesteguia 2007-03-29 04:55:38 EDT
Yes, it was always fast. I'm developing an application to show information from /proc. I have never had this problem before with the same machine. The battery of my machine seems to be fine: normal duration and normal charging time.
