Using the eco power plan

This computer may be equipped with the eco power plan. Operating

the computer with this power plan enabled reduces electrical power

consumption by slightly lowering system performance. For

example, when this power plan is enabled, the brightness of the

display is reduced and the interval before Sleep mode takes effect is

shortened. To enable or disable the eco power plan, see “Power

Plans” on page 89.

The eco Utility

monitors your power savings from using the eco

power plan by tracking real-time power consumption and

accumulated savings over time. To learn how to access the utility,

see “eco Utility

” on page 112.

For more information on the eco power plan, see the Help file in the

eco Utility

window.

Changing the main battery

When your main battery has run out of power, you have two

options: plug in the AC adaptor or install a charged 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 and computer.

❖ 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.

Removing the battery from the computer

To remove the battery:

1 Save your work.

2 Turn off the computer, see “To Shut down your computer” on

page 42.
