Thanks. I checked in that file, and Enable laptop Mode is on False at me. The clicks cannot be heard while the AC adapter is plugged in. Only temperature is high. For example, while writing this email, no other application running, it is 51 Ccelsius degree. How can I check if the HDD is spinning continously? I used the commands from http://www.overclockingwiki.org/forums/showthread.php?t=1645 and I found there were 0.2 cycles per minute (12. ... cycles per hour) in this case.
But when AC adapter is unplugged and the laptop is running on batery only, the temperature starts decreasing, but the clicks can be heard in this case, one click each 3 or 4 seconds, annoying. .... I was thinking (empirically.....): what about disabling APM power management in Bios, or turning somehow acpi off, or perhaps that Laptop Mode is switching on while running on batery? I don't know what to do.... --- On Fri, 7/3/09, Philip Muskovac <yo...@gmx.net> wrote: From: Philip Muskovac <yo...@gmx.net> Subject: [Bug 394826] Re: HDD unusual high temperature and activity in Ubuntu Jaunty To: emailstude...@yahoo.com Date: Friday, July 3, 2009, 3:39 PM Thanks. As for Laptop mode: it's set int /etc/default/acpi-support # Switch to laptop-mode on battery power - off by default as it causes odd # hangs on some machines. (Note: This is reported to cause breakage in # Debian - see deb bug #425800. Leaving enabled for Ubuntu for now # since presumably it's still valid here.) ENABLE_LAPTOP_MODE=false This should be always false unless you change it by hand. Also if you want to try changing the power managemant of you hd by hand try hdparm (-B and -S would be what you want I think) -- HDD unusual high temperature and activity in Ubuntu Jaunty https://bugs.launchpad.net/bugs/394826 You received this bug notification because you are a direct subscriber of the bug. Status in Ubuntu: New Bug description: My hard disk temperature is pretty high (above 45 Celsius degrees) even if I just read an article without any other activity. Also, I can hear the noise of the hard disk permanently, at every 3 or 4 seconds it is moving. I have a Fujitsu Siemens Esprimo Mobile V6545 laptop with Ubuntu 9.04. So: iotop -o (after previously installed iotop) gives me, for a fraction of a second, commands like: gnome power management, kjournald, pidgin and one or two more. But each dissapeared very quickly. The Command column is empty now, for a long time has been empty. The temperature (sudo hddtemp /dev/sda) is 48 Celsius degrees now. I remarked (repeating it) that the temperature starts decreasing after I unplugg the AC adapter so that the laptop is running on battery only. But it was 58 Celsius degree, with Pidgin running only. The annoying click of the hard disk can be heard at each 3 or 4 seconds. The hard disk is WD3200BEVT. Its specification may be found at http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=2670&p_created=#jumper. -- HDD unusual high temperature and activity in Ubuntu Jaunty https://bugs.launchpad.net/bugs/394826 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
