tlp.conf

# ------------------------------------------------------------------------------
# /etc/tlp.conf - TLP user configuration
# See full explanation: https://linrunner.de/tlp/settings
#
# New configuration scheme (TLP 1.3). Settings are read in the following order:

# 1. Intrinsic defaults
# 2. /etc/tlp.d/*.conf - Drop-in customization snippets
# 3. /etc/tlp.conf     - User configuration (this file)
#
# Notes:
# - In case of identical parameters, the last occurence has precedence
# - This also means, parameters enabled here will override anything else
# - However you may append values to a parameter already defined as intrinsic
#   default or in a previously read file: use PARAMETER+="add values"
# - IMPORTANT: all parameters here are disabled, remove the leading '#'
#   to enable them; shown values may be suggestions rather than defaults
# - Default *: intrinsic default that is effective when the parameter is missing
#     or disabled by a leading '#'; use PARAM="" to disable an intrinsic default
# - Default <none>: do nothing or use kernel/hardware defaults

# ------------------------------------------------------------------------------
# tlp - Parameters for power saving

# Default: 1

#TLP_ENABLE=1

# Operation mode when no power supply can be detected: AC, BAT.
# Concerns some desktop and embedded hardware only.
# Default: <none>

#TLP_DEFAULT_MODE=AC

# Operation mode select: 0=depend on power source, 1=always use TLP_DEFAULT_MODE
# Note: use in conjunction with TLP_DEFAULT_MODE=BAT for BAT settings on AC.
# Default: 0

#TLP_PERSISTENT_DEFAULT=0

# Power supply class to ignore when determining operation mode: AC, BAT.
# Note: try on laptops where operation mode AC/BAT is incorrectly detected.
