6.3.4 Low-Battery Warning
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 6.1 Power Management.
6.3.5 Charging the Battery
When connected to an electrical outlet, a completely discharged 6 cell battery
needs to be charged in 3.5 to 12 hours, and a 9 cell battery in 4.5 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.
6.3.6 Removing the Battery
Before removing the battery, ensure your notebook is turned off.
1. Move the battery lock to switch to the right (Unlock position).
2. Slide and hold the battery to release latch.
3. Remove the battery.
