“Battery Recalibration” does not increase the battery’s capacity. If “Battery Recalibration” is executed frequently, dete-
rioration of the battery may result.
z
If you have two or more battery packs, perform the “Battery Recalibration” for each battery pack.
z
If the computer is turned off during the “Battery Recalibration” (e.g., due to power failure, or accidental removal of the
AC adaptor and battery pack), the “Battery Recalibration” will not be completed.

You can also perform the “Battery Recalibration” with the following procedure.

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.
