Chapter 4 Power system
43
Using Battery Power
A fully-charged battery pack provides the Notebook PC a few hours of working
power. But the actual figure varies depending on how you use the power saving
features, your general work habits, the CPU, system memory size, and the size of
the display panel.
Checking Battery Power
To check the remaining battery power, move your cursor over the power icon.
The power icon is a “battery” when not using AC power and a “plug” when using AC
power. Double click on the icon for more information and settings. The following
example is that of Windows XP.
NOTE: If you ignore the low battery warning, eventually the Notebook PC enters sus-
pend mode (Windows default uses STR).
WARNING! Save-to-RAM does not last long when the battery power is depleted.
Save to Disk (STD) is not the same as power OFF. STD requires a small amount of
power and will fail if no power is available due to complete battery depletion or no
power supply (e.g. removing both the power adapter and battery pack).
WARNING! Never attempt to remove the battery pack while the power is ON, or if
the system has not yet entered into the suspend mode as this may result in the data
loss.
Move your mouse over the battery icon for
remaining power information.
