The computer powers of without warning when the battery discharges. It causes loss of data because it does not turn off but instead the power goes out when the battery is dischaged. Add a warning notification that will tell the user when the battery power is low. Also make it possible for the user to set the computer to automatically hibernate when the battery power drops below a certain level.
also add a sound alert BUT NOT A BEEP SOUND
The gnome-power-manager application already does all of this. As noted in the package description, powertop is used to find applications that are causing wakeups and thereby draining power from your machine. It does not do power management, which is what you describe. I suggest that you look into gnome-power-manager, or the KDE equivalent if you are a KDE user.
I am a gnome user but what I mean is add such a feature by default so when the OS is installed it already has it.
