MORE INFORMATION

To determine what is preventing the computer from starting Standby mode, you can check the following log file

<WINDOWS>\Susfail.txt

where <WINDOWS> is the path and folder where Windows is installed.

If the log file is empty or does not exist, you may use the Power Management Troubleshooter (Pmtshoot.exe) tool to determine which program, driver, or hardware device is preventing Standby mode from starting.
