Lenovo ThinkPad P14s (AMD) Gen 4

S3 sleep / s2idle

S3 (deep) sleep is not supported by this CPU anymore. However, s2idle works out of the box and causes no problems with sleep / hibernation.

The sleep power consumption with s2idle (or S0/S0ix/Modern Standby) can vary as it depends on the running OS and how well it can put peripherals into sleep mode.

Hibernate

Works fine. If you face Wi-Fi issues after hibernation see #Wi-Fi.

Battery thresholds

Battery charge thresholds can be correctly set with TLP or within KDE / GNOME power management.

AMD P-State EPP

If you are using power-profiles-daemon, please note that the current stable release of it do not fully support AMD P-State EPP. You can switch to TLP version 1.6 or newer that supports AMP P-State features, or fix this using an udev rule + script to apply different AMD P-State EPP states depending on whether the laptop is running on battery or charger.

Power Profiles Daemon

The package power-profiles-daemon is the standard power management service for KDE#Power management and GNOME#Power modes. It conflicts with TLP and the reasons for that are described here: https://gitlab.freedesktop.org/upower/power-profiles-daemon#why-not

1. Install power-profiles-daemon
2. Start/enable the power-profiles-daemon service.
