Over the last week, my desktop has refused to turn the screen off or sleep as prescribed in the power settings. The reason APPEARS to be that something is repeatedly updating the "Last Activity" date and time, making the system believe that there is still an active user. I use an app called SmartPower to manage when periods of On/Off time. and the logs from this app indicate that the system remains active due to "user activity" under my username..
I have also turned of, and uninstalled this app (SmartPower) to test whether it is the cause. I set up the necessary power plan values in the power settings, but still the machine will not sleep or turn the screen off.
Other diagnostics I have tried include:
- Changing my mouse. I recently installed a new Logitech M510 mouse, along with Logitech "LOGI+ Options." I uninstalled both the mouse and the software.. I also installed a different, older mouse onto a different Logitech receiver.
- Restarted with startup items off.
- Several other options I found on other sites that do not really match my situation.
Finally, looking back on the SmartPower debug log, I see that the last successful "power off" sequence occurred around 10:50am last Sunday (Oct 22), and restart was initiated at 11:24am . As best I recall, I was nowhere near my computer at that time - nor was anyone else! But from then, every minute thereafter, the log reports 2 changes to the last activity date/time every minute.
A perfect answer to this would be ideal, but , maybe, as a starting point, someone could tell me if and how there is a way to determine which process is updating the last activity date and time every 30 seconds or so, even though there is no user activity from the keyboard or mouse.
Thanks for any help!
