iBook, PowerBook Data Loss Problem Noted -- Apple has issued a Tech Info Library article cautioning iBook and PowerBook (FireWire) owners of a potential data loss problem with those portable Macs. Under certain low-memory situations, putting the machine to sleep with the "Preserve memory contents on sleep" option enabled can overwrite essential file system data. When restarted, the laptops display a flashing question mark; after booting from a CD-ROM, the hard disk fails to appear and Disk First Aid reports errors that cannot be repaired. Apple is working on a software fix to be released at the end of March. In the meantime, Apple recommends disabling the "Preserve memory contents on sleep" feature. [JLC]
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
