Full Power Mode
Your la
to
o
erates in Full Power mode when
ou set Heuristic
Power Mana
ement to
Disabled
in the BIOS Setu
ro
ram. This
o
tion is located on the Power Savin
Menu. In Full Power mode,
all
ower mana

when
ou are o
eratin

Power Management
Power mana
ement allows
ou to maximize s
stem
erformance
while savin
ower. The SA200 uses an innovative
ower
mana
ement techni
ue called Heuristic Power Mana
ement.
Most com
uters use timer-based
ower mana
ement. You set
timeout timers to determine when the com
uter should save
ower
on a device. The
roblem with this is that no two users are alike.
Each one of us has his or her own habits when usin
the com
uter.
This makes timer-based
ower mana
ement ineffective.
Heuristic Power Mana
ement allows
our com
uter to mana
e all
ower mana
ement. You do not need to set timers because the
com
uter d
namicall
sets timeout timers de
endin
on how
ou
use the com
uter.
The LCD screen and backli
ht come on when
ou use the
ke
board or move the
ointin
device, and the hard disk returns to
full
ower the next time it is accessed.
