Sleep Mode
If you have to interrupt your work, you are able to turn off the power without
exiting from your software by placing the computer into Sleep Mode. In this
mode data is maintained in the computer's main memory so that when you
turn on the power again, you can continue working right where you left off.
When you have to turn off your computer aboard an aircraft or in places
where electronic devices are regulated or controlled, always completely
shut down the computer. This includes turning off any wireless
communication functionalities, and cancelling settings that reactivate the
computer automatically, such as a timer recording function. Failure to
completely shut down the computer in this way could allow the operating
system to reactivate and run pre-programmed tasks or preserve unsaved
data, which could interfere with aviation or other systems, possibly causing
serious injury.
Before entering Sleep Mode, be sure to save your data.
Do not install or remove a memory module while the computer is in
Sleep Mode. The computer or the memory module could be damaged.
Do not remove the battery pack while the computer is in Sleep Mode
(unless the computer is connected to an AC power source). Data in
memory could be lost.
