The battery pack is a consumable item, and deteriorates gradually each time it is used.
Use effective switching of the Economy Mode (ECO) to reduce battery pack deterioration, and enable the battery pack to last
a little longer. Switch the Economy Mode (ECO) in accordance with the way you use your computer.
z
Economy Mode (ECO) disabled:
In the default setting, the Economy Mode (ECO) is set to
“
Disabled.
”
Charge the battery to 100% (fully charged). We recommend that you disable the Economy Mode (ECO) if you use the bat-
tery pack frequently.
z
Economy Mode (ECO) enabled:
Stop the battery recharging at 80% of fully charged. By stopping the battery recharging before 100% (fully charged), the
burden on the battery is reduced and deterioration is prevented, so the lifetime of battery pack will be extended. The com-
puter will not operate as long on the battery as when Economy Mode (ECO) is disabled.
If you often use the computer with the AC adaptor connected, and if you want to prevent deterioration of the battery pack,
we recommend that you enable the Economy Mode (ECO).
