ViewSonic VS13235 manual Power Meter, Low-Battery Warning, Charging the Battery

2.2.3 Power Meter

The power meter indicates the remaining battery charge. When your notebook is running on

battery power, you can double click the icon on the taskbar to check the remaining battery

charge. If you want to know more details about how to make the icon appear on the taskbar if it is not already, please see 7.1 Power Management

2.2.4 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 7.1 Power Management.

2.2.5 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 an 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.
