CAUTION: While in Sleep mode, your computer will maintain system
information and open files. Unsaved information will be lost if you turn off your
system prior to system wake-up, or if you lose power while using the AC
adapter.
Hibernation Mode
Hibernation helps conserve battery life and protects your data. Hibernation can be a routine power
saving event, or can be the result of a low battery condition. As it enters Hibernation your computer will
display a progress screen, as it automatically saves the machine state before it shuts down and turns
itself off. Your computer will automatically go into Hibernation, when the battery has little power left, or
when the system (operating on battery power) has been in Sleep mode for more than an hour. You can
also manually initiate Hibernation by pressing the power button once while the system is active. To
restore the computer's previous state, simply press the power button once again. While waking up, the
computer will display a progress screen.
