Computer comes up black with power save mode

Hi,

When I turn my computer off for the night and turn it on the next morning, the screen stays black with the message “entering power save mode”. And there is nothing I can do to get the screen back! My settings have power save mode OFF. It says “no power saving!” and turn off display and put computer to sleep are set to “never”.

The only way I could get my screen back on was to unplug the monitor and plug it back in.

My wonderful new Windows 11 computer is one of the most frustrating I’ve ever had. The previous Windows 10 was the BEST I ever had. So they ruined it with their “upgrade” and forced the upgrade. I hate computer “improvement upgrades”! They always make things worse. End rant.

Does your monitor have a power saving mode? I was checking and apparently many do apparently…doc

Good question.
Well, I found an energy setting for the monitor but nothing about power saving mode. Just:
Power Button LED - on or off during active
Reset energy settings.
That’s all.

My monitor is a samsung and I looked it up with AI. It gave me instructions on how to change it. Maybe you can do the same thing…doc

In my experience the setting for display power saving is not on/in the display - rather it is in the computer operating settings.

I tried that. No luck. I’m not seeing a menu item they mentioned.

I’ve already turned the ones in the computer settings to “never”. See OP.

I saw that. I have my computer set up the same way. I have one monitor (Samsung) going into standby but the other one doesn’t. I’m sure its not the OS, so it has to be the monitor. I have to press the toggle button to get it to come back on for a sleep setting (guessing)…doc

The weird thing is that if the computer is off and I turn it on, the monitor stays black and enters power saving mode. What does it think I want to do when I turn the computer on? Stare at a black screen? LOL.
I’ll tinker again later when I have time.

I googled and was surprised and the number different settings within Windows 11 on this issue. I know in Apple land it too easy to miss one setting on a topic and have an unexpected result. Here is the link to a video which I hope has off the settings issues.

Thanks. Going through the video. I already have the energy saver off.
But I have no “lower screen brightness” option. Odd. Why does he and I don’t? No worries. I don’t think that’s an issue.
I also already have “best performance” on.
And I have the “never” choices already set.
I guess I’ve done what I can.

Not certain, but that sounds kind of familiar. When I see something like it (or exactly that?) I’ve always believed it is my monitor. My monitor is an LG. What brand is yours?

I don’t use it, but my LG monitor has an on/off switch, a button underneath, right behind the LG logo centered below the screen. I would expect your monitor to have one somewhere, regardless of brand or model. I think that would be more convenient than pulling the plug. If it works.

I have a Dell monitor. But I don’t see an on/off switch anywhere. It has a power button that turns the screen off but it doesn’t power it down like pulling the plug.

Model number? ………………

I don’t know the model # and Dell is pathetic in that they only list orders for the past two years! Seriously?!
Note that order records are only accessible for two years.

That’s ridiculous! I’ve spent TONS of money on Dell for decades and they can’t keep those records?
Anyway, that is how I was hoping to see the model #. I see a s/n on the back and some other long numbers, but they are hard to read because the stupid label is behind all the cables. I would have to unplug all the cables in the monitor to see what’s there.

Ok. How about a picture or two of the front and back? I’m sure it could be found to match something quite similar on line.

Take a picture of the plate/info on the back. It may be a sticker. It should have the model number. If you see it yourself, google-up the owner’s manual for that model.

I have my computer (Win10) set up to turn off the monitor after a set time, and hibernate if it’s inactive for a bit longer. Jiggling my trackball ends either mode, as it should.

Mine also is a Dell monitor. It does give me a power-down mode message when there is no signal to the monitor. When a signal returns (e.g. turn on the PC, or jiggle the trackball if it’s in one of the low power modes), the monitor exits that mode.

I’m assuming this is a new problem for you, so it is quite possible something has gone wrong in your monitor. Not catastrophic (yet), but annoying. I would be guessing about the root cause, so I’ll refrain for now.

I looked up the SVC number c0jk092 at Dell. Here’s your monitor: Support for Dell UZ2315H | Overview | Dell US

Not much help there unfortunately, but googling for “Dell UZ2315H” gets the 67 page user guide and other potentially useful stuff.

Do you have the Dell Display Manager application installed? It might give options to change the power settings of the monitor.

See https://dl.dell.com/manuals/all-products/esuprt_display_projector/esuprt_display/dell-uz2315h_user’s%20guide2_en-us.pdf

Dell Display Manager User’s Guide

Once installed, Dell Display Manager will run each time the system starts and will place its icon in the notification tray. Information about monitors connected to the system is always available when hovering over the notification tray icon.
