S2340T, Windows 8, screen saver setting

I have a new S2340T with Win 8.1 and HDMI and USB connections.  I have the screen saver setting for ribbons and to wait 10 minutes.  The problem is that the screen saver never activates and the screen never goes dark.  I'm afraid of leaving it on all night and burning the pixels.  Thanks.

RE: screen saver setting

Hi brentwoodcomputer,

I would suggest you to check the Power Options settings on the computer and also, please reinstall the video card drivers on the computer to check if it fixes the issue.

Thanks Ravi.   Now, the screen saver comes on and then goes into sleep (dark) when left in any program, BUT still doesn't work when left in desktop.

RE: S2340T, Windows 8, screen saver setting

Did you install the Dell Display Manager software? If yes, open it, click the options tab, remove the check from PowerNap options.

Perhaps the monitor settings are also confusing the operating system power management settings.
* Press the monitor #3 Menu button to open the OSD (On Screen Display)
* Go to Other Settings
* Energy Smart = Off
* Go to Green Modes = Off

SOLUTIONfor screen saver not starting up and notebook won't shut down

I know this is an old thread, but Dell would not let me create a new thread. I have Vostro 5470 and had the same problem: screen saver not starting up.

At first I blamed the bug in Windows 8.1, but during my research (believe me, it took a while), Microsoft pointed out that the problem with screen saver not starting up might not be due to Windows, instead, there might be a running application that stops the screen saver from starting up. So I looked at my running applications again, and since Dell Support Assist agent has been a pain so far (resource hogger), started on that.

Turns out, the culprit is DellUpdate service. I set it to manual, restart the computer and the screen saver works like magic.

That was for Windows 8.1. Now that I have upgraded to Windows 10, the problem starts again. This time I noticed a pattern: If my screen saver could not start up, then the notebook will not turn off later.

Let me explain the "notebook will not turn off" part. The situation is when you turn off the computer from Windows: the turn off sequence will start like normal and the screen will turn off (black). You will wait for the power light indicator to turn off too to indicate shut down. But the power and the fan will not turn off, indefinitely, or until it runs out of battery. You will end up having to press the power button for several second to force shut down. Not pretty.

This time I checked DellUpdate service, and the setting stayed manual. So something else must be the culprit this time around. Then I noticed PC-Doctor keeps starting up several minutes after start up. PC-Doctor is not a service. Turns out it is a task. So open your Window's Task Scheduler, look for task named PCDoctorBackgroundMonitorTask. Disable the task. Restart. Your screen saver problem and turn off problem is solved!

For added measure, and since  Dell's applications are mostly intrusive and resource hogger, especially DataVault (it makes video playback stutter), I also set these services to manual:

- Dell Support Assist Agent

- Dell Data Vault

- Dell Data Vault Wizard

Before another Dell representative comes up with the "those are necessary to keep your system updated', well, I can manually check for updates, without having to suffer from Dell's half-baked softwares.
