Sleep Memory Extension Blocks Laptop Bug

Apple‘s new Sleep Memory Extension helps protect iBook and PowerBook (FireWire) computers from data loss or corruption when using the "Preserve memory contents on sleep" feature under low memory situations (see "iBook, PowerBook Data Loss Problem Noted" in TidBITS 521). The extension, a 184K download, disables the "Preserve memory contents on sleep" checkbox in the Energy Saver control panel. This (obviously) disables the computer’s ability to preserve memory contents to disk for recovery in the event of total power loss during sleep; however, it also prevents users from stumbling into the data loss problem associated with the feature. We still expect Apple to address the actual problem in an upcoming software release; in the meantime, at least this extension keeps users out of harm’s way. The extension works on English and localized versions of the Mac OS, although the ReadMe file is only available in English.
