# Configuration file for MCE - udev battery plugin

[BatteryUDevSettings]

# Settings related to orking around missing / too

# infrequent udev change notifications about power

# supply devices.

# Some devices might not send udev notifications

# about all power supply devices e.g. PinePhone at

# the moment does notify about charger disconnect,

# but not about battery making simultaneous

# transition to discharging state.

#

# It is possible to instruct udev battery plugin to

# poll all power supply devices whenever notification

# about change in one is received.

#

# This is relatively costly operation and should be

# enabled only when necessary.

#

# To enable:

#

# RefreshOnNotify = true

#

# Default is:

#

# RefreshOnNotify = false

# For similar purposes mce can be instructed to track

# USB state changes reported by extcon subsystem devices.

#

# On its own this is not overtly costly, but chances

# are that when it is needed, also RefreshOnNotify=true

# should be used.

#

# To enable:

#

# RefreshOnExtcon = true

#

# Default is:

#

# RefreshOnExtcon = false

# Many/most of devices do not send udev notifications

# on every battery capacity percent change. Most of the

# times this is harmless. However it can also cause

# battery empty shutdown to be delayed so much that

# battery is too depleted for regular bootup.

#

# To avoid this udev battery plugin polls all power

# supply devices in process watchdog heartbeat pace

# i.e. about every 36 seconds of uptime not spent in

# suspend.

#

# To disable this periodic polling:

#

# RefreshOnHeartbeat = false

#

# Default is:

#

# RefreshOnHeartbeat = true
