We are trying to implement the “recommend” big fix power settings
Turn off monitor = 30 minutes
Turn off hard disk = 1 hour
System Stand by = 1 hour
Hibernate = never
these work fine for the user when the go to lunch or are away from their work station for under 5 hours . They return and just have to move the mouse or activate the key board . The issue if it seems to be longer than 5 hours the machine goes into a deeper sleep ( like an s4 ) to wear you have to soft power the machine back on . Any ideas what might be controlling that or how it could be changed . I have checked Bios and system settings and there is nothing that looks like it would control this.
we needs these machine to remain in the lighter sleep so that we can remote into the machines or run scans . When they are in the deeper sleep you can not . Yes I know we could do wake on lanes …but this is to understand why this deeper sleep happens.
This is something that i’ve never fully understood myself. From my understanding, it’s usually not that the computer has gone into a deeper sleep state, but that the mechanism to wake up the computer change or stop working (like the machine stops monitoring usb input devices).
Do the power settings appear to be correct on desktops with this issue?
Does it happen on a specific desktop model, or set of models? Try to narrow it down.
Have you tried updating the BIOS?
We had a similar, but not necessarily the same, issue with Dell Optiplex 755s that we were putting into S3 standby. If they were in standby for 15 minutes or less, you could wake them with the keyboard. If it was any longer, you had to press the power button to wake them. It seems silly, but this confuses and annoys a lot of users.
I eventually narrowed down the problem when, after disabling Intel AMT, the problem went away. Dell eventually released a BIOS update to fix the AMT issue.
