我的问题很不妙
我的thinkpad t43 上用了laptop-mode, 并且我设置为始终使用laptop-mode, 接电源时硬盘保持工作状态，不spin-down.
可是我查了一下，有时5分钟之內，数值就增大了20。
下面使我的laptop配置文件，我把laptop-mode 放在default runlevel中。谢谢，请高手替我看看

#
# 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.

###############################################################################
# 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=1

# power? (ACPI-ONLY)

###############################################################################
# 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.
###############################################################################

# adjust hard drive spindown timeouts. These parameters specify which
# devices and partitions are affected by laptop mode.

# 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.

# CPU frequency scaling and throttling

###############################################################################
# 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?
CONTROL_SYSLOG_CONF=0
# Laptop mode tools controls syslog.conf by replacing /etc/syslog.conf (or
# whatever you specify in SYSLOG_CONF) by a link to the files configured here.
# NOTE: these files are NOT created by default, and if they do not
# exist this feature will not work. You can run the script
# /usr/sbin/lm-syslog-setup to set things up.

# lm-ac-start, nolm-ac-stop and nolm-ac-start. Laptop mode will call the
# scripts in a state-"stop" directory with the "stop" parameter when entering
# the state in question, and it will call the same scripts with the "start"
# parameter when leaving the state. Scripts in a state-"start" directory are
