    Power Management Beeps on Thinkpads

    + +

    + When disconnecting or connecting the charger, a beep occurs. + When the battery goes to a critically low charge level, + a beep occurs. Nvramtool is included in libreboot, and can + be used to enable or disable this behaviour. +

    + +

    + Disable or enable beeps when removing/adding the charger:
    + $ sudo ./nvramtool -w power_management_beeps=Enable
    + $ sudo ./nvramtool -w power_management_beeps=Disable +

    + +

    + Disable or enable beeps when battery is low:
    + $ sudo ./nvramtool -w low_battery_beep=Enable
    + $ sudo ./nvramtool -w low_battery_beep=Disable +
