Monitoring battery power


NOTE Depending on your system, the RTC battery may only charge while the device is turned on.

To recharge the RTC battery, plug the device into a live electrical outlet and leave the device powered on for 24 hours.

NOTE It is seldom necessary to charge the RTC battery because it charges while the device is on. If the RTC battery is low, the real-time clock and calendar may display the incorrect time and date or stop working.

When Hibernation mode is enabled and the RTC battery is completely discharged, a warning prompts you to reset the real-time clock.

The device can be used while the RTC battery is being charged, although the charging status of the RTC battery cannot be monitored.

Monitoring battery power

The device’s main battery light gives you an indication of the main battery’s current charge.

❖ Glows amber while the main battery is being charged

(AC adaptor connected)

Glows white when the main battery is fully charged

NOTE Battery life and charge time may vary, depending upon power management settings, applications and features used.

Flashes amber when the main battery charge is low and it is time to recharge the main battery or plug in the AC adaptor

NOTE If the AC power light flashes amber during charging, either a battery pack is malfunctioning, or it is not receiving correct input from the AC power supply.

HINT: Be careful not to confuse the battery light ( ), the power light ( ), and the power button light.

When the power light or power button light flashes amber, it indicates that the system is suspended (using the Windows ® operating system Sleep command).

Determining remaining battery power

NOTE Wait a few moments after turning on the device before trying to monitor the remaining battery power. The device needs this time to check the battery’s remaining capacity and perform its calculations.

Move the pointer over the power icon in the notification area,

see “Finding your way around the desktop” on page 82

for more information on the notification area. A pop-up message displays the remaining battery power as a percentage.

With repeated discharges and recharges, the battery’s capacity gradually decreases. A frequently used older battery does not power the device for as long as a new battery, even when both are fully charged.

Monitoring battery power


TECHNICAL NOTE: The device drains the battery faster at low temperatures. Check your remaining charge frequently if you are working in temperatures below 50 degrees Fahrenheit.

The device calculates the remaining battery charge based on your current rate of power use and other factors such as the age of the battery.

What to do when the main battery runs low

When the main battery runs low you can:

Plug the device into an external power source and recharge the main battery

❖ Save your work and turn off the device

If you do not manage to do either of these things before the main battery completely runs out of power, the device automatically enters Hibernation mode and turns itself off.

Hibernation mode keeps track of where you were, so that when you turn on the power again, you can continue where you left off.

Setting battery notifications

You can set two notifications. Each notification can be set to alert you when a specified percentage of remaining battery power has been reached. You can also set the device to enter Sleep mode or Hibernation mode or to completely shut down when the notification goes off.

To change the default notification settings:

1 While on the desktop, click or touch the Battery ( ) icon in the notification area.

2 Click or touch More power options .

The Power Options window appears.

3 Click or touch Change plan settings under the power plan to be customized.

The Edit Plan Settings window appears.

4 Click or touch Change advanced power settings .

The Advanced settings tab of the Power Options window appears.

Conserving battery power

How long a fully charged battery pack lasts when you are using the device depends on a number of factors, such as:

How the device is configured

How much you use the internal storage drive, optical disc drive, or other optional devices

❖ Where you are working, since operating time decreases at low temperatures

There are various ways in which you can conserve power and extend the operating time of your battery:

❖ Enable Sleep or Hibernation, which saves power when you turn off the device and turn it back on again

Use the Windows ® power-saving option plans

Mobile Computing

Monitoring battery power


These power-saving options control the way in which the device is configured. By using them, you can increase the length of time you can use the device before you need to recharge the battery.

Microsoft ® has combined these options into preset Power

Plans. Using one of these power plans lets you choose between maximum power savings and peak system performance. You may also set individual power-saving options to suit your own needs.

The following sections describe how to choose a Power Plan and discuss each power-saving option.

Power Plans

You can choose a predefined Power Plan or select your own combination of power options.

To do this:

1 While on the desktop, click or touch the Battery ( ) icon in the notification area.

2 Click or touch More power options .

The Windows ® Power Options window appears.
