Hello everyone!
After several years of Debian and Red Hat based distros, I’m happily trying Manjaro for the first time!
I’ve insalled Manjaro XFCE 21.0.7, Kernel 5.10.42-1 on my secondary laptop (Acer Aspire 1, Celeron N4120) and tuned TLP a little bit, managing to get an amazing battery life of 8-9 hours. Unfortunately I’m facing a quite annoying issue: when I turn on or reboot the laptop, TLP seems that it’s not working: the CPU is stuck at >2GHz: I’ve tried to restarting tlp wth sudo tlp start, but nothing changes. But if I suspend and wake up the system, TLP starts working properly.
What could it be?
Here’s my tlp.conf file.
Thanks 
# ------------------------------------------------------------------------------
# /etc/tlp.conf - TLP user configuration
# See full explanation: https://linrunner.de/en/tlp/docs/tlp-configuration.html
#
# 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
# - 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
# Set to 0 to disable, 1 to enable TLP.
