Hallo,
Ik heb een probleem met Ubuntu 10.10. De laptop wordt namelijk met dit OS erg warm, iets wat met Windows 7 niet zo is.
Hier is de output van acpi -V:

Dit is na 5 minuten gebruik. De temperatuur stijgt binnen no-time naar 77 graden.

An audio device is active 100.0% of the time:
hwC0D0 IDT 92HD75B3X5
A USB device is active 100.0% of the time:
/sys/bus/usb/devices/1-1
Suggestion: Enable Device Power Management by pressing the P key
Suggestion: Enable USB autosuspend for non-input devices by pressing the U key
Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with:
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
This wakes the disk up less frequently for background VM activity
Suggestion: Enable SATA ALPM link power management via:
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
or press the S key.
Suggestion: Enable wireless power saving mode by executing the following command:
iwconfig wlan0 power timeout 500ms
This will sacrifice network performance slightly to save power.
Suggestion: enable HD audio powersave mode by executing the following command:
echo 1 > /sys/module/snd_hda_intel/parameters/power_save
or by passing power_save=1 as module parameter.
Suggestion: Enable the CONFIG_PM_ADVANCED_DEBUG kernel configuration option.
This option will allow PowerTOP to collect runtime power management statistics.

Overigens heb ik al de patch van
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/524281/+index toegepast, ook zonder resultaat.
De temperatuur stijgt zonder dat de laptop gebruikt wordt.
De specificaties van de laptop zijn overigens:
Intel Core i7 720QM 1,6 GHz
NVIDIA Quadro FX 880M
Iemand enig idee?
Bij voorbaat dank,
Donenzone
edit:
ik zie nu pas in GNOME System Monitor dat één processor altijd een load heeft van ongeveer 70%. Kan het proces echter niet vinden.
