Full Power Mode
Your la

erates in Full Power mode when
y

g
ement to

in the BIOS Setu
p
p

ram. This
o
p
tion is located on the Power Savin
g
Menu. In Full Power mode,
all

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