Charging batteries
The RTC battery powers the RTC memory that stores your
system configuration settings and the current time and date
information. It maintains this information for up to a month
while the computer is turned off.
TECHNICAL NOTE: Depending on your system, the RTC
battery may only charge while the computer is turned on.
Power management
Your computer ships with the power management options
preset to a configuration that will provide the most stable
operating environment and optimum system performance for
both AC power and battery modes.
Changes to these settings may result in system
performance or stability issues. Users who are not
completely familiar with the power management
component of the system should use the preset
configuration. For assistance with setup changes,
contact Toshiba’s Customer Support Center.
