47 Mobile computing
TECHNICAL NOTE: The computer drains the battery faster at low
temperatures. Check your remaining charge frequently if you are
working in temperatures below 50 degrees Fahrenheit.
The computer calculates the remaining battery charge based on your
current rate of power use and other factors such as the age of the
battery.
TECHNICAL NOTE: When your computer is using all of the power
provided by the AC Adapter to run applications, features, and
devices, the recharging of the battery cannot occur. Your computer's
Power Saver utility can be used to select a power level setting that
reduces the power required for system operation and will allow the
battery to recharge.
HINT: Be careful not to confuse the battery light ( ) with the on/off
light ( ). When the on/off light flashes amber, it indicates that the
system is suspended (using Windows
®
XP Standby command).
Setting battery alarms
Your computer can be configured to warn you when the
battery is running low. For more information, see “What to do
when the battery alarm sounds” in the electronic user’s guide.
Changing the main battery
When your main battery has run out of power, you have two
options: plug in the AC adapter or install a fresh main battery.
Never short circuit the battery pack by either accidentally or
intentionally bringing the battery terminals in contact with another
conductive object. This could cause serious injury or fire, and could
also damage the battery pack.
Never expose a battery pack to abnormal shock, vibration or
pressure. The battery pack's internal protective device could fail,
causing it to overheat or ignite, resulting in caustic liquid leakage, or
explosion or fire, possibly resulting in death or serious injury.
TECHNICAL NOTE: To avoid losing any data, save your files and
then either completely shut down your computer, or put it into
Hibernation mode before changing the main battery.
