Salve a tutti,
dopo aver letto vari forum vorrei fare il punto della situazione sulla configurazione del risparmio energetico
sul mio portatile (Dell Latitude D630).
Come prima cosa vorrei chiedervi come avete risolto, per chi lo avesse, il problema delle cycle_count elevato.
Come avete configurato laptop-mode.conf?
C'è una guida o un howto dove è spiegato come risolvere il problema?
Nel mio caso, attualmente il file laptop-mode.conf è questo:
#
# Set this to 1 if you want to see a lot of information when you start/stop
# laptop_mode.
#
VERBOSE_OUTPUT=0
###############################################################################
# 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.
###############################################################################
#
# Enable laptop mode when on battery power.
#
ENABLE_LAPTOP_MODE_ON_BATTERY=1
#
# Enable laptop mode when on AC power.
#
ENABLE_LAPTOP_MODE_ON_AC=0
#
# Enable laptop mode when the laptop's lid is closed, even when we're on AC
# power? (ACPI-ONLY)
#
ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=0
###############################################################################
# When to enable data loss sensitive features
# -------------------------------------------
#
# When data loss sensitive features are disabled, laptop mode tools acts as if
# laptop mode were disabled, for those features only.
#
# 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.
###############################################################################
#
# Disable all data loss sensitive features when the battery level (in % of the
# battery capacity) reaches this value.
#
MINIMUM_BATTERY_CHARGE_PERCENT=3
#
# Disable data loss sensitive features when the battery reports its state
# as "critical".
#
DISABLE_LAPTOP_MODE_ON_CRITICAL_BATTERY_LEVEL=1
###############################################################################
# Controlled hard drives and partitions
# -------------------------------------
#
# For spinning down your hard drives, laptop mode will remount file systems and
# adjust hard drive spindown timeouts. These parameters specify which
# devices and partitions are affected by laptop mode.
###############################################################################
#
# The drives that laptop mode controls.
# Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a
# wildcard, which will get you all your IDE and SCSI/SATA drives.
#
HD="/dev/[hs]d[abcdefgh]"
#
# The partitions (or mount points) that laptop mode controls.
# Separate the values by spaces. Use "auto" to indicate all partitions on drives
# listed in HD. You can add things to "auto", e.g. "auto /dev/hdc3". You can
# also specify mount points, e.g. "/mnt/data".
#
PARTITIONS="auto /dev/mapper/*"
#
# If this is enabled, laptop mode tools will assume that SCSI drives are
# really SATA drives that only _look_ like SCSI drives, and will use hdparm
# to control them. Set this to 0 if you have /dev/sd devices and you want
# laptop mode tools to use the "sdparm" command to control them.
#
ASSUME_SCSI_IS_SATA=1
[color=red]
###############################################################################
# Hard drive behaviour settings
# -----------------------------
#
# These settings specify how laptop mode tools will adjust the various
# parameters of your hard drives and file systems.
###############################################################################
#
# Maximum time, in seconds, of work that you are prepared to lose when your
# system crashes or power runs out. This is the maximum time that Laptop Mode
# will keep unsaved data waiting in memory before spinning up your hard drive.

# Should laptop mode tools control readahead?
#
CONTROL_READAHEAD=1
#
# Read-ahead, in kilobytes. You can spin down the disk while playing MP3/OGG
# by setting the disk readahead to a reasonable size, e.g. 3072 (3 MB).
# Effectively, the disk will read a complete MP3 at once, and will then spin
# down while the MP3/OGG is playing. Don't set this too high, because the
# readahead is applied to _all_ files that are read from disk.
#
LM_READAHEAD=3072
NOLM_READAHEAD=128
#
# Should laptop mode tools add the "noatime" option to the mount options when
# laptop mode is enabled?
#
CONTROL_NOATIME=0
# Should laptop use relatime instead of noatime? The "relatime" mount option has
# more standards-compliant semantics, and allows more applications to work,
# while retaining a low level of atime updates (i.e., disk writes).
USE_RELATIME=1

# Should laptop mode tools control the hard drive idle timeout settings?
#
CONTROL_HD_IDLE_TIMEOUT=1
#
# Idle timeout values. (hdparm -S)

# for battery and for AC with laptop mode on.

# Power management for HD (hdparm -B values)

# Should laptop mode tools control the hard drive write cache settings?

In particolare come avete impostato le seguenti voci?
LM_AC_HD_IDLE_TIMEOUT_SECONDS=300
LM_BATT_HD_IDLE_TIMEOUT_SECONDS=300
