Save-to-disk suspend mode — To activate this feature, press <Fn><a> (or 
<Fn><q> on the French keyboard) or set the Suspend Time-Out option in 
the Power Menu of the Setup program. To resume using the computer, press 
the power button. The computer may take several seconds to return to nor-
mal operation. If you connect or remove devices while the computer is in 
save-to-disk suspend mode, the computer automatically recognizes the 
newly connected devices when it resumes normal operation. If you encoun-
ter problems with a PC Card after resuming from save-to-disk suspend 
mode, remove and reinsert the PC Card. When the battery is nearly 
depleted, the computer enters save-to-disk suspend mode to preserve system 
data.
