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 slide and release the power switch.
Note:  If the sleep indicator is off, the computer has entered 
Hibernation mode and turned off.  If the power indicator is off 
but the sleep indicator is on, the computer has entered Sleep 
mode.  In both cases, slide and release the power switch to turn 
the computer back on.  Note that the computer may enter 
Hibernation mode after it is in Sleep mode for a period of time.
What to bring to short meetings
A fully charged battery runs the computer for about 3 hours under 
most circumstances.  If your meeting is shorter than that, you probably 
do not need to bring anything with you other than the computer.
What to bring to long meetings
If your meeting will last longer than 3 hours 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.
If the meeting room does not have an electrical outlet, reduce the 
drain on the battery by putting the computer in Sleep mode.  Press Fn-
F4
 or close the display cover whenever you are not actively using the 
computer.  To resume, open the display (if closed); then slide and 
release the power switch.

Preparing the computer
After disconnecting the computer from your desktop, follow these 
steps to prepare the computer for the trip home:

from the drive(s). Failure to remove the media can damage the 
drive head.
