Important Battery Tips
How to Use the Battery with Minimal Deterioration
The battery is a consumable and, as such, its performance will gradually deteriorate.
This deterioration is accelerated under the following conditions.
- When the battery is repeatedly charged
- When the battery is used or charged in a place with high temperature
To minimize deterioration of the battery and ensure a longer battery life, you must reduce the number of charges and ensure that the temperature inside the battery does not become too high.
Bear in mind the following points.
Charge the Battery in a Temperature Range of 10ºC to 30ºC {50ºF to 86ºF}
In places where the outside air temperature is high, the temperature inside the battery will also become high.
Do not charge the battery inside a vehicle with all its windows closed and exposed to the hot sun or in other places where the temperature is high.
This computer's battery will not be charged if its temperature is outside the allowable range.
(At such a time, the battery indicator blinks orange.)
We Recommend Charging the Battery No More than Once per Day
Recharging the battery after every small use raises the total number of battery charges and speeds battery deterioration.
To lower the total number of battery charges, we recommend recharging the battery no more than once per day or when the remaining charge drops to 10% or less.
With this computer, in order to reduce the number of charges, the battery will not be recharged immediately after it has been fully charged unless the remaining charge has fallen to less than 95%.
Charging the Battery While the Computer is Powered Off is Recommended
If the computer's power is on, the temperature inside the battery rises due to the effects of heat from the CPU and other components.
We recommend that you only charge the battery when the computer is powered off.
How to Use the Computer to Maximize the Battery Operation Time
Decrease the Internal LCD Brightness
The power consumption is reduced by decreasing the brightness.
Before Stepping Away from Your Computer, Enter the Sleep
Pressing the power switch will put the screen go to sleep, thereby lowering the power consumption.
We Recommend Against Using Applications that Place a Significant Load on the CPU
Some applications place a large load on the CPU.
When using these applications, a significant load is placed on the CPU even when the computer is not being used.
We recommend that you do not use applications that will drain the CPU.
Remove Peripheral Devices (USB devices, external display, etc.) When Not in Use
Disable Wireless Devices When it is Not in Use
You can disable Wi-Fi, Bluetooth and wireless WAN by using "
Airplane mode".
Similarly, the power consumption is reduced by disabling GPS.
Shorten the Timeout Period

Things to Keep in Mind When Using the Battery Pack
Charging Time and Discharging Time Differs Depending on the Computer's Power Status and Temperature
- It takes longer to fully charge the battery when the computer's power is on.
To charge the battery more quickly, power the computer off, or put it in sleep.
- It takes longer to fully charge the battery in low temperature environments.
The battery discharges more quickly in low temperature environments.
