SUMMARY

Power management features have been known to cause invalid page faults or other fatal errors in application software, or even cause application software to show "Not Responding" after periods of inactivity. Power management features have also been known to cause network errors if a Network Interface Card (NIC) has power management features enabled. It is possible that disabling power management could correct these problems.

MORE INFORMATION

Power management features were designed to conserve energy, reduce hardware wear and tear, and reduce noise. When these features are enabled, the computer or certain components (i.e., monitor, hard drive, printer) act as though they are turned off during periods of inactivity but make themselves available upon request. However, not all device drivers are written to support power management properly and loss of data can result. Also, conflicts can occur when power management features are enabled and software is running that requires the computer to be in a fully powered state (a hard drive that is in standby mode can take several seconds to return to full power).

Power management is standard in Windows 98/Me/2000/XP.  It is not available for Windows NT. For example, Windows 2000/XP computers have power management settings for system standby, the monitor and the hard drive (In Windows 2000 Start | Settings | Control Panel | Power Options, or in Windows XP Start | Control Panel | Performance and Maintenance | Power Options). Furthermore, power management settings for your NIC and other devices can be configured via the Windows Device Manager (Control Panel | System | Hardware | Device Manager).

Power management features are found at both the system BIOS level and operating system level.  These areas must have power management features disabled to completely turn off power management. In addition, these features need to be disabled at both the workstation level and the server level (Our Technical Support Staff is not responsible for helping users change power management features). Please contact a qualified computer technician, reseller or vendor for assistance or visit Microsoft's Web site (www.microsoft.com) and search for the keywords "power management."

Note: Power management should not be enabled on any machine that is a server. However, it is usually okay to implement power management on the monitor.

Note: It is important to note that these types of problems occur in other software products and are not unique to Tabs3 software.
