zWe recommend against using applications that place a significant load on the CPU.

Some screen saver place a large burden on the CPU even when you are not operating the computer.

We recommend that you do not use a screen saver.

NOTE

zTo extend the battery operation time, activate the power saving function of the USB2.0 Root Hub.

tery operation time.

tions.
