Minimizing battery pack
degradation
The battery pack is a consumable item. The battery
pack lifetime varies greatly depending on how the
computer is used and the usage environment. We
recommend the following actions to minimize the
battery pack degradation and lengthen its lifetime as
much as possible.
Set Economy Mode (ECO) to “Enable”.
•
Charge the battery in a temperature range of 10°C
•
to 30°C.
Charge the battery no more than once per day.
•
Charge the battery while the computer is powered
•
off.
Battery’s Economy Mode (ECO)
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. In the default settings,
the battery’s Economy Mode (ECO) is disabled to
prioritize the battery’s operating time.
If required, switch to the battery’s Economy Mode
(ECO) to make more efficient use of the battery.
When the AC adaptor is frequently
connected
Economy Mode (ECO) enabled:
•
The battery pack degradation is minimized
•
because charging is stopped at 80% of the
full charge.
We recommend this if battery operation is not
•
required for a long time.
When used frequently on the move
Economy Mode (ECO) disabled:
•
Charging up to 100% is possible.
•
We recommend this when the battery
•
operating time is prioritized.
Switching the Battery’s Economy
Mode (ECO)
1
Click on the notification area and then click
.
2
Click [Enabled] or [Disabled] in [The battery’s
Economy Mode (ECO)].
