Battery Low Warnings - Sharp PC-AR50 Manual

Battery Low Warnings

The battery low warnings are set in Windows Power Options Properties dialog box.
Click Alarms tab, and you can set a Low battery alarm and a Critical battery alarm.
The alarms are triggered when battery charge decreases to a user-defined percentage
set.
3
We recommend that you set the Low battery alarm to about 10% and the Critical
battery alarm to about 3-5%. The battery charge percentages are not extremely
accurate and the power consumption of different applications are not identical, so
it's important to allow for a margin of error. The primary aim is to save your data
before the system shuts down when the battery is fully discharged.
Following the battery low alarms that you have set, we recommend that you save
your work and shut down your computer when there is about 5% of battery charge
remaining. In this condition, you can be confident that you have enough power to
power the hard disk drive, CD-R/RW drive or floppy disk drive and save even the
longest of files.
