Configuring a Virtual Machine 176
Optimizing Power Consumption
This option allows you to control the virtual machine power consumption when Parallels
Desktop is installed on a Mac laptop computer that is running on batteries (for example,
MacBook Pro):
 If you select Longer battery life in the Power consumption field, the virtual machine power
consumption will be automatically reduced to provide a longer life for your Mac laptop
battery.
 If you select Better performance, the virtual machine and its applications will operate at the
maximum possible speed. However, enabling this option may significantly reduce your Mac
laptop battery life.
If you select the Enable battery in virtual machine option, the battery status will be displayed in
your virtual machine each time your Mac laptop computer runs on batteries. This option is
available only on laptop Macs.
If you want to prevent Virtual Machine Configuration from further unauthorized changes, click
the Lock icon
at the bottom of the window. The next time someone wants to change the
settings on any pane of Virtual Machine Configuration, an administrator's password will be
required.
