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.
■ Make sure the Hard Disk Drive/Optical Disc Drive indicators are off. 
If you turn off the power while a disk (disc) is being accessed, you may 
lose data or damage the disk.
■ Never turn off the power while an application is running. Doing so could 
cause loss of data.
■ Never turn off the power, disconnect an external storage device or remove 
storage media during data read/write. Doing so can cause data loss.
Do not turn the computer or peripheral devices back on immediately - 
wait a short period to avoid any potential damage.
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 
switches or devices, and canceling 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.
