ÄCAUTION: Make a habit of saving your work before allowing your notebook to enter Standby. If power is interrupted while the notebook is in Standby, any information that was not saved will be lost.
The notebook can also enter Hibernation if battery power reaches a critically low level. If this happens, you will find on resuming that all your data has been saved, but some functions may be disabled. To resume normal operation, restore power by connecting an AC adapter or installing a charged battery pack, then turn the notebook off and restart it.
