linux禁用充电功能,lenovo thinkpad t460s opensuse linux 保护电池设置电池充电阀值
对于经常接AC的用户来说,电池保持在40%-80%之间可以让电池生命周期更长久
由于我的t460s有两块电池,分别设置
linux-pw37:~ # cat /etc/default/tlp
# Battery charge thresholds (ThinkPad only, tp-smapi or acpi-call kernel module
# required). Charging starts when the remaining capacity falls below the
# START_CHARGE_THRESH value and stops when exceeding the STOP_CHARGE_THRESH value.
# Main / Internal battery (values in %)
START_CHARGE_THRESH_BAT0=40
STOP_CHARGE_THRESH_BAT0=80
# Ultrabay / Slice / Replaceable battery (values in %)
START_CHARGE_THRESH_BAT1=40
STOP_CHARGE_THRESH_BAT1=80
重启tlp.service
linux-pw37:~ # systemctl restart tlp.service
linux-pw37:~ # tlp stat -v -b

下面是tlp官方的介绍
ThinkPads only
START_CHARGE_THRESH_BAT0=75
STOP_CHARGE_THRESH_BAT0=80
START_CHARGE_THRESH_BAT1=75
STOP_CHARGE_THRESH_BAT1=80
Set ThinkPad battery charge thresholds for main battery (BAT0) and auxiliary/Ultrabay battery (BAT1).
Values are given as a percentage of the full capacity. A value of 0 is translated to the hardware defaults
96 / 100%.
Charging starts upon connecting AC power, but only if the remaining capacity is below the
value of START_CHARGE_TRESH (start threshold). Charging stops when reaching the
STOP_CHARGE_TRESH (stop threshold) value. If, however when you connect the AC adapter, charge is above
the start threshold, then it will not charge.
Note: the charge threshold settings are disabled by default and must be enabled explicitly by
removing the leading '#'.
ThinkPad T420(s)/T520/W520/X220 (and all newer models): check .
