The notebook also writes all current memory (RAM) information to the hard drive similar to Hibernate mode. If your notebook experiences a power outage while in Hybrid Sleep mode, the notebook reads the memory information from the hard drive and opens the programs and documents that were open when you activated Hybrid Sleep mode. If the notebook does not experience a power outage while in Hybrid Sleep mode, it restarts using the information in current memory, thus reducing startup time. You must turn on Hybrid Sleep mode to use it. For more information, see “Changing advanced settings” on page 75. Using power saving modes Always save your work before using Sleep mode. In Sleep mode, your notebook reduces or turns off the power to most devices except memory. However, the information in memory is not saved to the hard drive.
