For optimum DVD performance, Toshiba recommends that you
play DVDs while running on AC power rather than on battery
power.
The QosmioPlayer is not a Windows-based application.
Battery life is less than when using similar applications in the
Windows Operating System.
Over a period of time, and depending on the usage of the
computer, the brightness of the LCD Screen will deteriorate.
This is an intrinsic characteristic of LCD technology.
Screen will dim when the computer is operated on battery
power and you may not be able to increase the brightness of
the screen
.
When playing DVDs using QosmioPlayer, the computer must
either be off or in Hibernation mode for QosmioPlayer to start.
If the computer is powered on or in Standby mode, turn off the
computer before trying to start QosmioPlayer.
Power management
Your computer ships with the power management options
preset to a configuration that will provide the most stable
operating environment and optimum system performance for
both AC power and battery modes.
