IBM ThinkPad 310E/310ED: User's Guide
Your computer has built-in battery power-saving functions to save
power when you use the battery pack or AC Adapter.
When resuming normal operation from one of the modes, use the
resume function to return to where you were when you entered that
mode. Because the operating system is already loaded, the resume
function is faster than turning on the power.
The following are the two power-saving modes:
•
Standby mode (Fn+F7). You can enter standby mode for short
idle times, such as when you are taking a short break from work.
•
Hibernation mode (Fn+F8). You can enter hibernation mode
when you leave your office for the day.
It takes more time to return to normal operation from hibernation
mode than to return from standby mode, but the computer does not
use power.
