Initiating standby, hibernation or shutdown
The following sections explain when to initiate standby or hibernation and when to shut down the computer.
NOTE You cannot initiate any type of networking communications or perform any computer functions while the computer is in standby or hibernation.
When you leave your workWhen standby is initiated, your work is stored in random access memory (RAM), and then the screen is cleared. When the computer is in standby, it uses less power than when it is on. Your work returns instantly to the screen when you resume from standby.
Initiating hibernation saves your work to a hibernation file on the hard drive, and then shuts down the computer. When the computer is in hibernation, it uses much less power than when it is in standby.
When the computer will be unused and disconnected from external power for an extended period, shut down the computer and remove the battery to extend the life of the battery.
When a reliable power supply is unavailableBe sure that hibernation remains enabled, especially if you are operating the computer on battery power and do not have access to an external power supply. If the battery fails, hibernation saves your work to a hibernation file and shuts down the computer.
If you pause your work when the power supply is uncertain, take one of the following actions:
●Save your work, and then initiate standby.
●Initiate hibernation.
●Shut down the computer.
When using wireless communication (select models only), infrared (select models only), or readable or writable media
CAUTION To prevent possible audio and video degradation, or loss of audio or video playback functionality, do not initiate standby or hibernation while reading or writing to a CD, a DVD, or an external media card. To prevent loss of information, do not initiate standby or hibernation while writing to a CD, a DVD, or an external media card.
Standby and hibernation interfere with the use of wireless communication, infrared, and media. Note the following guidelines:
●If the computer is in standby or hibernation, you cannot initiate an infrared or wireless transmission.
●If standby or hibernation is accidentally initiated during playback of a medium such as a CD, a DVD, or an external media card:
●Your playback may be interrupted.
●You may see the following warning message: "Putting the computer into hibernation or standby may stop the playback. Do you want to continue?" Click No.
●You may need to restart the media to resume audio and video playback.
