Sensors
Thiscomputerisequippedwithfoursensors(accelerationsensor,gyrosensor,magneticsensor,
ambientlightsensor),andyoucanusethesesensorswithanysoftwarethatiscompatible.
Astheaccuracyofeachsensoroutputisdependentontheoperatingenvironmentandothercon-
ditions,theresultsshouldonlybeusedasareference.
Theaccelerationsensor,gyrosensor,andmagneticsensorarelocatedatthebottomleftofthe
LCD.Thedetectionresultsofeachsensormayvarydependingonhowyouareholdingthecom-
puter,theapplicationsoftwareyouareusing,andotherfactors.

Automatic brightness adjustment
 Thecomputerisequippedwithanautomaticbrightnessadjustmentfunctionthatadjuststhe
displayscreenbasedontheambientlightsensor.Youcanconguretheautomaticadjustment
functionasfollows.
A
 Click
(Start)atthelowerleft,andthenclick (Settings)-[System]-[Display].
B
 Set[Changebrightnessautomaticallywhenlightingchanges]to[On].
CAUTION

The[Adjustmyscreenbrightnessautomatically]itemmaynotbeavailableinsomecases.In
suchcases,clickthearrowtotheleftof[Settings]atthetopleftofthescreen,andperform
theoperationfrom[System]-[Display]again.
A
 Click(Start)-[ControlPanel]-[HardwareandSound]-[PowerOption].
B
 Click[Changeplansettings]forthepowerplancurrentlyused.
C
 Click[Changeadvancedpowersettings]anddouble-click[Display].
D
 Double-click[Enableadaptivebrightness],makenecessarysettings,andclick[OK].
SeteachitemtoON,andthebrightnessofthescreendisplaywilladjustautomatically.
 TheambientlightsensorislocatedatthetopofLCD.
 Theambientlightcannotbedetectedproperlyifthisareaisobstructedordirty.

Magnetic sensor
 Themagneticsensoronthecomputeroperatesbydetectinggeomagnetism.Therefore,the
magneticsensormaynotfunctionproperlyanditreadingsmaybeinaccurate,especiallyin
thefollowingenvironments.

Insideornearsteelstructuressuchasbuildingsorbridges

Insideornearautomobiles,orneartrainpowerlines

Nearmetallicfurnitureorappliances

WhentheACadaptororotherperipheraldevicesarebroughtclosertothecomputer

Nearmagnets,speakers,orotherobjectswithstrongmagneticelds
 Themagneticdirectionsindicatedbythemagneticsensormaynotbeaccurateimmediately
afterpurchaseorinenvironmentswithpoormagneticelds.
Insuchcases,turnonthecomputerandmoveitasfollows.
A
 Holdthecomputersothatitsscreensideisfacingupwardandlevel.
B
 Whilekeepingthecomputerlevel,rotateit90degreesormoreclockwise.
C
 Returnthecomputertoposition
A
,androtateit90degreesormorecounterclockwise.
D
 Returnthecomputertoposition
A
.
E
Tiltthecomputer90degreesormoretotheleftsothattheleftsideofthecomputertiltsdown.
F
 Returnthecomputertoposition
A
,andtiltit90degreesormoretotherightsothatthe
rightsideofthecomputertiltsdown.
