With Hardy Heron on a Dell Vostro 1400, Load_Cycle_Count was increasing 2-5 times per minute with AC and battery. Setting ENABLE_LAPTOP_MODE=true in /etc/default/acpi-support fixed that problem. /proc/sys/vm/laptop_mode was set to 2 prior to that. With the change, among other things the APM level for the disk (valued used for hdparm -B) is set to 1 on battery and 254 on AC. I am still watching the temp on AC to determine if 254 is OK. Priot to setting ENABLE_LAPTOP_MODE=true, I manually changed the APM level to 1 and 127, but that did not solve the problem.
