The gauge has three sections:
∙The top section shows you whether or not power management is turned on.
An icon of a water faucet that is dripping water indicates that power management is enabled and the computer is using minimum battery power.
An icon of a water faucet with a full stream of water indicates that power management is turned off and the computer is using maximum battery power.
To turn power management on or off, press <Fn+F6> to display the battery gauge and then press <F1> until the icon for power management or the icon for no power management appears. The setting you choose will remain in force even after you turn off the computer.
∙The middle section of the gauge shows a picture of a battery to indicate that the computer is operating from the battery.
∙The bottom section of the gauge shows you the approximate amount of battery charge remaining. F means that the battery is at full charge. E means that the battery is completely discharged.
While the battery gauge is displayed, all keys except <F1>, <Fn+F3>, and <Esc> are disabled. The battery gauge closes in a few seconds, or you can press <Esc> to close it.
You can also use the <Fn+F3> key combination to turn power- management on and off. Power management reverts to its previous setting when you turn off the computer.
Because of the characteristics of battery cells, the battery gauge may be inaccurate for 10 minutes after you charge the battery. Wait until the computer has been operating from the battery for 10 minutes before you check the battery gauge.
