Question Display randomly turn itself back on , system is set to ' Never '.

[unicorn2015anahiem]

I have a problem with my pc....

In Power Options , i have set my Display to turn off after 3 minutes of inactivity , which it did.... but at random interval, it will turn itself back on... without touching mouse and keyboard.... which is strange...

Windows is set to ' Never ' in Power Options.

anyone know what causes this?

I have disabled the Network card and Intel 1219-V's power option to never wake up my pc... only devices that can wake is only Mouse and Keyboard.

WakeTimers in Power Options's advanced settings is disabled too.

using command prompt (administrator) with command ' powercfg -lastwake ' shows nothing .. it shows ' wake History Count - 0 '

Anyone can help? Googling around is somewhat different than mine.

the Power Options:
USB settings > USB selective suspend setting
or PCI Express > Link State Power Management
are usually the culprit when i've had this type of issue.

make sure both are "disabled" or "off" and see if the issue persists.

Thanks, just followed your guidance ... Disabled both settings.

You mean that your issue is where the Display randomly turn itself back on? and Windows is set to ' Never ' turn off?

if i am correct, when Display is set to turn off after specified amount of time, the signal feed to Monitor/Display is cut off, and that trigger the Monitor to go into Power saving state ( screen black, power led blinking ) right?

and only moving/clicking mouse and tapping the keyboard will only wake it, right?

oh yes, could a mouse malfunction or getting crazy and causes the cursor in the window to move even a little, when physical mouse on desk haven't been touched? could this be a possibility?

I uses Logitech G603 and G613 Mouse and keyboard , which is wireless.

For some reason when I turn it to full speed both the back fan and radiator fans run.

yes, when certain data is accessed by Windows it will react just as if you were awakening the display.
the same situation can arise with your Display's "sleep" settings, and/or the OS' own sleep/hibernate states.

random "pulses" to your devices by Windows will cause the system/display to awaken. you just need to determine what device is causing it.

my G Hub software doesn't seem to have any "sleep/awaken" options of it's own so i doubt it's the LG software causing it.

could a mouse malfunction or getting crazy and causes the cursor in the window to move even a little, when physical mouse on desk haven't been touched? could this be a possibility?

this would definitely cause the issue though.

You mean Mouse could causes something like that? while i am using pc, i don't see the mouse's cursor twitching or moving...

So thinking if it could be my G603 sensor go haywire , i switched the mouse OFF, and the screen still wake itself after 2 - 3 minutes after the screen went into sleep .

It couldn't be keyboard, right?

 

[JohnBonhamsGhost]

it could be any type of USB device.

and not necessarily a USB device at all. it could also be your motherboard irregularly checking device status or even just malfunctioning. or many other number of things.

one possible easy solution could be to update to the latest system BIOS, reinstall latest version of Windows, then install all latest motherboard system drivers.

 

[unicorn2015anahiem]

I only have two USB devices connected, only mouse and keyboard via USB dongle.

Shall try updating Bios or reinstall windows.... and update here again.

 

[unicorn2015anahiem]

so, updated BIOS , ME, IntelChipset to latest.

still it wake the screen itself....

shall update here if i find anything or tried anything new... help is much needed. Thank you.

 

[unicorn2015anahiem]

Tried updating Mouse firmware to latest i could find on Logitech driver support.... still monitoring...

Do you happen to have a shared folder or drive on this machine?
(sorry if already covered)

That (access of or polling of the drive) will cause the screen to become active.

so, updated BIOS , ME, IntelChipset to latest.

what is the "ME" you're referring to?

updating the chipset is only going to effect the CPU controller.
you need to install ALL of the latest drivers for your motherboard. it could be issues with LAN, USB, or anything else.

and you skipped the second step.

Forgive me, ME is referring to Intel MEI .... not sure what it does, just install anyway....

By you mean second step ( install windows again/clean wipe) , i can't install latest driver on my current windows? it's up to date though.

How do i check on that?

LOL... i want to try anything i can get now.... it's getting annoying.

Do you mean Shared Folder ?

after checking at ' Computer Management ' , it seems i don't have a shared folder.

https://prnt.sc/ryj7va, here's my screenshot of ' Computer Management '

 

[unicorn2015anahiem]

So I clean install windows... reinstalling latest drivers available of Z370F support page.

Shall monitor and update here.

 

[unicorn2015anahiem]

Okay, so after : Latest Bios > Wipe clean + new Windows installation > latest driver

at randomly it still turn the screen itself on .....

back when first installed from USB , it was much ealier version , i think about 1803.... i tried to monitor , it doesn't seem to wake up.... but on 1909 , the latest avaiable , i have a feeling it's the cause...

 

[JohnBonhamsGhost]

you can also check in the monitor's own OSD menu. there may be some settings regarding sleep modes and such.

 

[unicorn2015anahiem]

I uses an Dell U2719D....

If i am correct, when the PC stopped sending HDMI/DVI/DPI signals to the the Monitor, the Monitor will goes into Power Saving mode when it lost the signal after Windows stopped sending it due to the Sleep i set in Power Options ( 3 minutes )...

a Monitor can't possibly request a signal from the PC and thus awake itself, right?

on another note, my sisters's laptop also reportedly doing the same behavior.. while her's display is set to 30 minutes later ( duration shouldn't be a thing , right ? ).... and windows is set to ' Never ' sleep.

the Mouse and Keyboard is running on drivers provided by Microsoft.. her laptop's mouse is a Microsoft Wireless 2000...

Checked the OSD menu, nothing says ' Power ' or ' saving ' or power related, or wake up related options that i can see.....

 

[JohnBonhamsGhost]

no it would be a peripheral device's signal, a program or internal device communicating with Windows, or something similar that Windows has determined is a user accessing the computer.

go back through all of your Power Plan options and make sure "Allow wake timers" is disabled and recheck all other settings for any possible conflicts.

if some settings have sleep or power settings; set them to a maximum power/performance setting.
if devices are set to a type of sleep or low-power state, they may randomly wake up and cause the rest of the system to also awaken.

 

[unicorn2015anahiem]

So i go back through again on all the settings i can see in the ' Balanced ' in the Power Options.... selecting High Performance didn't work either. it still will randomly wake up, send a video signal, to wake the Monitor.

Disabled both ' allow wake timers ' , disabled link power state in PCI...... again.

my Keyboard is G613 , and when not in used for an extended period of time, it will go to ' sleep ' ... i can't find a setting that prevent it from doing so.... unless i tap a key, the keyboard will stay asleep and won't wake itself up. I doubt ' devices ' can do such a thing to wake the display from sleep, sending a signal to monitor, and the monitor is turned on after few minutes of going into sleep.

oh man, i am getting confused, the sleep setting should just work... nothing is running, no program is installed , a fresh windows with nothing installed?

 

[JohnBonhamsGhost]

I doubt ' devices ' can do such a thing to wake the display from sleep, sending a signal to monitor, and the monitor is turned on after few minutes of going into sleep.

it wouldn't be devices sending signals directly to your monitor.
it is Windows receiving signals and therefore awakening the screen; similar to if you touched a key, pushed the mouse, had a message pop-up from a certain program, or a remote connection or device accessing data.

 

[unicorn2015anahiem]

Yes, i know... what i mean is devices send some signal to windows and windows awaken the display. 😆 sorry, i mistype the ' sending a signal to monitor '. change it to ' windows '.

The windows is fresh install, nothing is installed, only thing is internet , and windows update is not running, after getting all the latest update up to 1909.

what else could it be?

 

[JohnBonhamsGhost]

were all system and device drivers installed previously when the issue started?
if not, maybe the lack of proper drivers is not allowing the sleep modes to function properly.
