[opgelost] Laptop wordt warm
« Gepost op: 2010/10/27, 20:43:01 »
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:

Battery 0: design capacity 5100 mAh, last full capacity 4979 mAh = 97%

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

Hier is de output van powertop -d:

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.

En na nog meer gegraaf blijkt dat het gaat om een bug in de BIOS van HP...

Bedankt iig.

Tijdelijke workaround is om echo disable > /sys/firmware/acpi/interrupts/gpe01 aan etc/rc.local toe te voegen of om te upgraden naar Linux-kernel 2.6.36.

Ja, die is hard aan het werk.

Even uitblazen met een compressor, of stofzuiger
