Battery Power
About High Temperature Mode
• The battery remaining displays 99% and the indicator light is orange for a long
period of time.
• Low battery warning appears after a short period of time.
This may be caused by the use of standby mode for long periods of time. The
battery is discharging while the computer is in standby mode when the AC adaptor
is not connected.
There may be a discrepancy between the % value that is displayed on the taskbar
icon, and [Power Meter] in [Power Options Properties]. This is not a malfunction.
This computer has a high temperature mode function that prevents the degradation of the
battery in high temperature environments.
To use the high temperature mode function, set [Environment] in the [Main] menu of the
*1
Setup Utility to [Auto] or [High Temperature]. In [Auto] mode, high temperature mode or
normal temperature mode is selected automatically depending on the battery status (the
internal temperature of the battery pack, etc.). Once the computer has automatically
switched from normal temperature mode to high temperature mode, the computer will not
switch back to normal temperature mode until the battery has been recharged from 0% to
100% about five times. This is to prevent deterioration of the battery.
Note that a level of 100% in the [High Temperature] mode is about a level of 80% in the
[Normal Temperature] mode.
After switching from [Normal Temperature] to [High Temperature], or vice versa, the
remaining battery will not be displayed properly until the battery pack is completely
discharged or fully charged.
