ThinkPad battery charge thresholds can be controlled through ACPI calls on models not covered by tp_smapi. tpacpi-bat installs the command, configuration, and dynamic-threshold systemd service for advanced laptop power management. ACPI writes affect battery firmware behavior, so confirm model support and keep recovery steps available.
