System 7.5.5 Update Installer & Energy Saver 1.x Issue

TECHINFO-0020448

TOPIC

This article describes an issue with the System 7.5.5 Update installer and the Energy Saver 1.x control panel.

DISCUSSION

Apple has discovered an issue in the System 7.5.5 Update installer that affects users who are updating a system with the Energy Saver 1.x control panel installed.

Details

• If a user has Energy Saver 1.x installed in the control panels folder, the System 7.5.5 Updater installation will fail with an error message stating the Energy Saver control panel must be moved.

• If Energy Saver 1.x has been disabled with the Extensions Manager control panel (and is in the disabled control panels folder), the installer will update it to a corrupted version of Energy Saver control panel 2.0.2.

• Users will be unable to open the corrupt Energy Saver file, and an error message is displayed stating that the file contains the Energy Saver Preferences and should be in the Preferences Folder.

Workaround

1. The work around is to remove the Energy Saver 1.x control panel from the System Folder, such as placing the control panel on the desk top, before installing the System 7.5.5 Updater.

2. When this is done, System 7.5.5 Update will not install Energy Saver Control Panel 2.0.2.

3. Energy Saver 1.x should then be placed back into the Control Panels folder after the update is done.

NOTE: Important information about this workaround.

• Energy Saver 1.x is only needed for those computers that have energy saving monitors but not the ability to put the whole system to sleep. This includes the NuBus-based Power Macintosh, some Performa PowerPC-based, and Macintosh Quadra computers.

• Energy Saver 2.0.x only works on desktop systems that support putting the whole system to sleep and not just the monitor, such as the PCI Power Macintosh computers.
