7.4 POWER MENU: 
 
 LCD Power Saving
:  
LCD exhausts the most part of power while the system is operating. S1A notebook system BIOS 
support auto backlight saving mode. When the system BIOS detects AC adapter removal, the LCD 
brightness is tuned down to 80 ﹪of its original setting, and back to normal when AC adapter is back 
inserted. 
Battery Calibration
:  
After long time incomplete charge/discharge cycles, the battery meter becomes less and less 
accurate (the total power capacity is not significantly affected, however). Battery gauge needs to “ learn”, 
this item helps users to recalibrate the battery gauge.In the learning process, users need to follow 
system BIOS instruction to insert/remove the AC adapter so that a complete reset and learning cycle 
may start.
