Save your data. While entering Hibernation Mode, the computer saves
the contents of memory to the hard disk drive. However, for safety
sake, it is best to save your data manually.
Data will be lost if you remove the battery or disconnect the AC
adaptor before the save is completed. Wait for the Hard Disk Drive/
Optical Disc Drive/eSATA indicator to go out.
Do not install or remove a memory module while the computer is in
Hibernation Mode. Data will be lost.
