Spadek wydajności po przejściu na baterie

[MarioX]

Witam,
Chodzi o to że gdy mam odłączone zasilanie z laptopa, jego szybkość strasznie spada.

Teraz moje pytanie, czy to może być spowodowane słabej jakości baterią, czy może złymi ustawieniami systemu?
Jeśli to drugie to co mam zmienić żeby laptop chodził na 100%?

[goferrr]

Jest to spowodowane dobrymi ustawieniami systemu, który usułuje oszczędzać baterię.
Poczytaj sobie o laptop-mode - po zainstalowaniu w pliku:

Kod: Zaznacz cały

sudo gedit /etc/laptop-mode/laptop-mode.conf

będzie mozna wymusić nieobniżanie częstotliwości procesora.
Druga możliwość do sprawdzenia to Monitor częstotliwości procesora dodawany do panelu Gnome.

Dzięki za odpowiedź,

kombinowałem z plikiem laptop-mode.conf, ale nie wiem jak ustawić żeby procek przy pracy na baterii osiągał 100% (teraz mam 800MHz na 1.80GHz)

Plik laptop-mode.conf:

# Configuration for Laptop Mode Tools
# -----------------------------------
#
# There is a "system" to the configuration setting names:
#    CONTROL_something=0/1   Determines whether Laptop Mode Tools controls 
#                            something
#    LM_something=value      Value of "something" when laptop mode is active
#    NOLM_something=value    Value of "something" when laptop mode is NOT
#                            active
#    AC_something=value      Value of "something" when the computer is running
#                            on AC power
#    BATT_something=value    Value of "something when the computer is running
#                            on battery power
#
# There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the
# available prefixes are different for each setting. The available ones are 
# documented in the manual page, laptop-mode.conf(8). If there is no LM_/
# NOLM_ in a setting name, then the value is used independently of laptop
# mode state, and similarly, if there is no AC_/BATT_, then the value is used
# independently of power state.
#
# Some options only work on ACPI systems. They are marked ACPI-ONLY.
#
# Note that this configuration file is a fragment of bash shell script: you
# can use all the features of the bash scripting language to achieve your
# desired configuration.
#
# 
# IMPORTANT: Laptop Mode Tools modules have separate configuration files, that
# can be found in /etc/laptop-mode/conf.d. Please look through these
# configuration files as well!

# When to enable laptop mode
# --------------------------
#
# "Laptop mode" is the mode in which laptop mode tools makes the computer
# consume less power. This includes the kernel "laptop_mode" feature, which
# allows your hard drives to spin down, as well as various other settings which
# can be tweaked by laptop mode tools. You can enable or disable all of these
# settings using the CONTROL_... options further down in this config file.

#
# Data loss sensitive features include:
# - laptop_mode (i.e., delayed writes)
# - hard drive write cache
#
# All of the options that follow can be set to 0 in order to prevent laptop
# mode tools from using them to stop data loss sensitive features. Use this
# when you have a battery that reports the wrong information, that confuses
# laptop mode tools.
#
# Disabling data loss sensitive features is ACPI-ONLY.

# devices and partitions are affected by laptop mode.
###############################################################################

# Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a

#
# The partitions (or mount points) that laptop mode controls.

# also specify mount points, e.g. "/mnt/data".
#

#
# If this is enabled, laptop mode tools will assume that SCSI drives are

# laptop mode tools to use the "sdparm" command to control them.

#
# Laptop mode tools can automatically adjust your kernel CPU frequency

###############################################################################
# Syslog configuration control
# ----------------------------
# 
# Syslog daemons have a tendency to sync their log files when entries are
# written to them. This causes disks to spin up, which is not very nice when
# you're trying to save power. The syslog.conf can be tweaked to *not* sync
# a given file, by prepending the log file name with a dash, like this:
#
# 	mail.*		-/var/log/mail/mail.log
#
# Using the following options, you can let laptop mode switch between
# different syslog configurations depending on whether you are working on
# battery or on AC power. To set this up, start by configuring these options
# for your syslog daemon, and then run lm-syslog-setup to create the various
# files. Then edit the laptop mode-specific syslog configuration files to
# remove the syncs only when laptop mode is active.
###############################################################################


#
# Should laptop mode tools control which syslog.conf should be used?
#

#
# Laptop mode tools controls syslog.conf by replacing /etc/syslog.conf (or

#
# Using these settings, you can let laptop mode tools control the X display

# This requires that you have installed the "xset" utility. It is part of the

#
# The X settings are not automatically applied on login, and this is
# impossible fix for the user, since laptop mode tools must operate as root.

# LCD brightness settings
# -----------------------
#
# Using these settings, you can make laptop mode tools automatically adjust
# your LCD's brightness settings. The settings are extremely simple -- they
# only allow for the execution of a command, nothing more. The reason for this
# is that LCD brightness settings are very different between laptop vendors.
#
# Suggestions for commands:
#
#  * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
#    be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
#    the command "echo <value>". The possible values can be listed using the
#    command:
#
#       cat /proc/acpi/video/VID/LCD/brightness
#
#  * If you have a file /sys/class/backlight/.../brightness, then you can use
#    that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
#
#    As far as I understand it the values are between 0 and
#    the value contained in the file /sys/class/backlight/.../max_brightness.
#
#  * For Toshiba laptops, use the command "toshset" with the -lcd or -inten
#    command. Read the toshset(1) manual page for more information on the
#    parameters for this command. If you use this command, set
#    BRIGHTNESS_OUTPUT to "/dev/null".

Hm... strzelasz do niewinnego W laptop-mode masz wyłączone zarządzanie częstotliwością, więc to nie on redukuje częstotliwość procesora... Sprawdź uruchomione usługi - w zależności od typu procesora, ta wartość może być sterowana przez powernowd, acpi, apm... możliwości jest wiele, a laptop-mode pod ubuntu to niestety dość ułomny potomek debianowego pierwowzoru...

Mam MSI VR610, procek: AMD® Mobile Turion64 X2

Jak mogę sprawdzić jaka usługa za to odpowiada?

Jak dla mnie to najprościej byłoby zainstalować np Kpowersave, który jak dla mnie jest doskonałym programem administrującym funkcjami oszczędzania energii. Tam masz zakładki w których możesz ustawić kilka rodzajów środowiska pracy. Między innymi opcjami jest zakładka dotycząca częstotliwości taktowania. Popróbuj tam ... Później jesli nie poskutkuje to zabieraj się dopiero za pliki konfiguracyjne... To moja prywatna opinnia oczywiście...
