Archived - Apple Portables: Wait for pulsing sleep indicator light before moving system

This article has been archived and is no longer updated by Apple.

When putting your Apple portable computer into sleep mode, be sure to wait a few seconds until the sleep indicator light starts pulsing before moving your Apple portable computer. The pulsing light indicates that the computer is fully asleep and the hard disk has stopped spinning.

Important: Moving your computer while the disk is spinning can damage the hard disk, causing loss of data or the inability to startup from the hard disk.
