battery indicator flashes while the battery is charging. See also “To charge the
battery pack” on page 10 for more information.
To remove the second battery pack
If you attach two battery packs, you can remove either of them without
shutting down the computer. When removing one battery pack, make sure
that the other battery pack’s indicator light is on. If the indicator light of the
battery pack you are removing is on, right-click the battery icon on the task
tray and click the “Switch discharge battery” option.
 There is a Release lever on the bottom of the weight saver. To remove the
battery pack, slide this lever in the direction of arrow 1, and then slide the
RELEASE lever on the bottom of the computer in the direction of arrow 2.
 Remove the weight saver, and then pull out the battery pack.
 Reinsert the weight saver. See “Using the Weight Saver” on page 37.
To determine the amount of time the battery lasts, see “Displaying Battery
Information” in the online document Customizing Your VAIO® Notebook.
