Chapter8 The Power System (Windows 7)
After a low-battery warning, save your work immediately and then connect your
notebook to an electrical outlet. Hibernate Mode will begin automatically if the
battery runs completely out of power.
You will hear the low-battery warning when the battery charge is approximately 90
percent depleted. Your notebook will beep once, indicating approximately 10 to 15
minutes of battery operating time remain. If you do not connect your notebook to
alternative power source during that time, there will be a periodic beep. Your
notebook will automatically enter
Hibernate Mode
if battery charge reaches a
critically low level. For more information, see
8.1 Power Management.
8.2.5 Charging the Battery
When connected to an electrical outlet, a completely discharged 4-cell battery
needs to be charged in 3.5 to 12 hours, and a 8-cell battery in 5 to 12 hours
(depending on whether your notebook is on or off and what programs are
running). You can leave the battery in your notebook as long as you like. The
battery’s internal circuitry prevents the battery from overcharging.
Before using the battery for the first time it must be charged. Connect your notebook
to an electrical outlet and allow the battery to fully charge, indicated by the battery
indicator light on the front panel of your notebook.
Once a battery pack is fully charged for the first time, please use your notebook on
battery power until the battery discharges completely. This will extend the battery
life, and helps to ensure the accurate monitoring of the battery capacity.
If necessary, the battery will be charged whenever your notebook is connected to an
electrical outlet.
The battery will not be charged if it or your notebook is too hot to use. If this
situation occurs, the battery indicator will light amber. Disconnect your notebook
from any electrical outlet, and allow it and the battery to cool down. You can then
reconnect your notebook to the electrical outlet and charge the battery. The
battery indicator will also light amber if the battery is bad and needs replacing.
