Taking your notebook PC with you - 59
Preparing the computer
Before moving the computer, close and latch the display cover to place it
in Sleep mode. You can now safely take the computer anywhere you go
within the building. To bring the computer out of Sleep mode, open the
display; then press and release the power button.
If you are taking the computer to a client's office or a different building,
you may choose to shut down the computer:
Click Start then click Shut Down.
Or:
You can put the computer in Sleep mode by pressing <Fn> + <F4>. Then
close and latch the display.
When you are ready to use the computer again, unlatch and open the
display; then press and release the power button.
Note: If the Sleep indicator is off, the computer has entered
Hibernation mode and is turned off. If the power indicator is off but
the Sleep indicator is on, the computer has entered Sleep mode. In
both cases, press and release the power button to turn the computer
back on. Note that the computer may enter Hibernation mode after
being in Sleep mode for a period of time.
What to bring to meetings
If your meeting is relatively short, you probably do not need to bring
anything with you other than your computer. If your meeting will be
longer, or if your battery is not fully charged, you may want to bring the
AC adapter with you to plug in your computer in the meeting room.
