Non-privileged users need to execute the
command xhost + after OpenWindows has
started for the PowerTool to pop up
automatically during low battery conditions.
This command grants other utilities (such as
the PowerTool) access to the screen. Refer to
the xhost(1) man page for more information.
Caution:
If power to the UltraBookIIi is
suddenly turned off and there is no available
battery power, the unit’s power management
features will not be able to perform a graceful
shutdown, which may damage important
system files. For more information on
shutting UltraBookIIi down, see page 3-10.
