6. Problem:Battery fuel gauge indicator icon is inaccurate.Power management
Action:The battery fuel gauge is a rough approximation of theproblems
actual battery capacity and is highly dependent on the
amount of energy you are using. As with an automobile,
the heavier you are on the accelerator, the fewer miles
you can travel before you hit Empty. Likewise, the more
you use the WinBook's power-hungry devices (hard disk,
floppy disk, or display) the less time you'll have on the
gauge.
Note that we have set the fuel gauge to reflect an average
user profile, with power management set to the default
settings. If you have power management disabled, the battery
gauge will perform differently.
The battery pack is nearing the end of its usable life,
and cannot sustain a full charge. The usable life of a
either battery option is approximately 500 cycles (de-
pending on operating, charging, and storage tempera-
tures). You can order a spare battery by contacting the
service number listed on your "Read-Me-First" sheet.
