I can also confirm this bug with Acer ASpire ONE 150 with HDD TOSHIBA MK1652GSX on Kubuntu 10.04 HDD temperature rises only when AC is plugged in. I have to manually set a lower -B setting on hdparm to prevent hdd temperature from going higher than in windows.
I also noticed that if I unplug and again plug the adapter, apparantly Ubuntu power devil reverts -B setting to a maximum level (or higher maybe), just so the HDD doesn't do head parking (load_cycle) excessivly. As a result its temp goes up :). So I guess maybe Ubuntu devs should set a lower default APM setting when the laptop is on AC, compromising a few load cycle counts for a more healthy HDD temperature :). Apparently doing some head parks when HDD is not used lowers it's temp and this is what Windows XP does by default on my netbook. -- Excessive heat versus excessive parkings https://bugs.launchpad.net/bugs/399978 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
