** Description changed: Hi, I have HP EliteBook 8440p with quadcore CPU, using Ubuntu 12.04 and Gnome-Shell 3 using two bateries. I noticed following: When batery comes under certain available power and/or when laptop is on power adapter and bateries are charging, until bateries are over 85% (not sure correct number), I can't change scaling_max_freq to maximum number. It stays on lowest possible freq and can't be changed. When bateries are over 85%, I can change this file. vi says : "E667: Fsync failed" when I try to save the chages. echo 2534000 > scaling_max_freq doesn't say anything, it just silently does nothing. I am using performance governor. This is my rc.local which I use to set frequencies and governour: echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor echo performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor echo 2534000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq echo 2534000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq echo 2534000 > /sys/devices/system/cpu/cpu2/cpufreq/scaling_max_freq echo 2534000 > /sys/devices/system/cpu/cpu3/cpufreq/scaling_max_freq And here is my /etc/sysfs.conf devices/system/cpu/cpu0/cpufreq/scaling_governor = performance devices/system/cpu/cpu1/cpufreq/scaling_governor = performance devices/system/cpu/cpu2/cpufreq/scaling_governor = performance devices/system/cpu/cpu3/cpufreq/scaling_governor = performance devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 2534000 devices/system/cpu/cpu1/cpufreq/scaling_max_freq = 2534000 devices/system/cpu/cpu2/cpufreq/scaling_max_freq = 2534000 devices/system/cpu/cpu3/cpufreq/scaling_max_freq = 2534000 /etc/init.d/ondemand is disabled. I changed all this files, because I got performance problems (cpu on maximum when using firefox and laptop was draging). Then I noticed that I can set cpu (with indicator-cpufreq) to more then minimum freq, so I found out that my scaling_max_freq is also on lowest frequency. uname -a Linux 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Bug is similar to this bugs? https://bugs.launchpad.net/ubuntu/+source/linux/+bug/396432 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/242006 + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + ApportVersion: 2.0.1-0ubuntu13 + Architecture: amd64 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: rodiger 2553 F.... pulseaudio + CRDA: Error: [Errno 2] No such file or directory + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0xd4720000 irq 48' + Mixer name : 'Intel IbexPeak HDMI' + Components : 'HDA:111d7603,103c172a,00100202 HDA:80862804,80860101,00100000' + Controls : 37 + Simple ctrls : 13 + CurrentDmesg: + Error: command ['sh', '-c', 'dmesg | comm -13 --nocheck-order /var/log/dmesg -'] failed with exit code 1: comm: /var/log/dmesg: Permission denied + dmesg: write failed: Broken pipe + DistroRelease: Ubuntu 12.04 + InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) + MachineType: Hewlett-Packard HP EliteBook 8440p + Package: linux (not installed) + PccardctlStatus: + Socket 0: + 3.3V + 16-bit + PC Card + Subdevice 0 (function 0) bound to driver "pata_pcmcia" + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.2.0-31-generic root=UUID=3fe8e16b-1daf-4197-8604-40a9f6f338cd ro splash quiet vt.handoff=7 + ProcVersionSignature: Ubuntu 3.2.0-31.50-generic 3.2.28 + Tags: precise + Uname: Linux 3.2.0-31-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: davfs2 sudo + WifiSyslog: + + dmi.bios.date: 03/09/2011 + dmi.bios.vendor: Hewlett-Packard + dmi.bios.version: 68CCU Ver.
