Saving Battery Power
battery operating time to be shorter than the time publicly
stated.
Do not remove memory when the computer is in
hibernation mode. If you do, the computer resumes from
hibernation mode without recognizing the changed
memory size. To ensure that the computer recognizes the
correct memory size, shut down; then restart your
operating system.
If the computer is powered with battery power, it turns
power off to the PC Card when entering hibernation mode.
When resuming normal operation, if the PC Card or
computer does not operate, restart the application or
computer.
If the computer is powered with AC power, it does not
enter hibernation mode if it is using one of the following
