I recently updated from Window 8.1 to Windows 10. The upgrade went fairly well except for my laptop monitor turning off after 1 or 2 minutes of inactivity. I have changed all power settings to appropriate times. At times, normally after a fresh restart, my screen saver kicks in correctly. However, after a few times of working correctly, my monitor begins to turn off again.
You might check the BIOS to see if there's a setting for the monitor, power saving, screen saver or something like that.
A year ago I bought a refurbished Dell Latitude E6400 through Newegg and the darn thing turned on as soon as I'd plug it in. I posted about it in sevenblog (laptop had Win7 Pro) and I was directed to go into BIOS, check for something related to that. I did that and there it was, a setting to power up when plugged in. I changed it to disabled and it fixed the problem.
That might not be the cause, but it sounds like you've set things in the OS, and BIOS would be about the only thing that would override the OS.
Thanks CmmTch. I checked the BIOS and nothing glaringly was available that will cause the issue. I have already downloaded the latest drivers for my display and video cards but to no avail. It might be a bug with Windows 10 that they have not figured out. I continue to download the latest windows 10 weekly updates in hopes that the fix will be in the latest downloads.
I have an integrated video chip, it's an ATI Radeon HD 4250, not much but it works fine for what I need. When I installed/upgraded to my present MB the cd that had the drivers on it included a Catalyst Control Center. It was an icon in the notification area of the taskbar when I had Win7, it had various adjustments for fine tuning a video card. I can't remember if it had anything on it about display settings, I don't think it did. You might check yours if there's something similar for your video.
It sounds like there's something somewhere that's either auto setting itself, or maybe it's unplugged and it's set to go off after 2 mins on battery power. I know in my laptop both at home and at work there are different choices/setting for if it's on ac power or battery power. I'm grasping at straws because as far as I know there just aren't that many different places to set that type of option.
There's always a chance even though it's plugged in the power cord/adapter could be starting to fail, or the connector that plugs into the laptop is defective. That might cause the laptop to be on battery and it appears to be on ac power.
At first I just thought my display turns off. It turns out that my monitor turns off because the system goes to sleep. For some reason, the system goes into sleep mode before the screen saver setting activates. After 2 or 3 minutes of inactivity, my laptop simply goes into sleep mode.
Sounds like you got that problem figured out, good job. Now you know what to adjust to prevent it, or if it's no big deal at least you know why it does what it does.
Thanks for posting back when you found the solution, there are many that come to windowssh blog after googling a problem or error and when we post back like you did we're helping other's.
I'm having the same problem. When I first got my laptop (ASUS n750jv) it had Windows 8, and I immediately upgraded to Windows 8.1. I had windows 8.1 with no problems, but ever since upgrading to Windows 10, the computer will go to sleep after 2 minutes. This doesn't always happen though. Usually after a reboot, it is fine. Then eventually if it's fallen asleep and I wake it up, it will always go back to sleep after 2 minutes of being idle. I've checked every setting I know of (system power and sleep settings, every power plan listed, even the advacned power settings) , I've updated my bios to the latest version, I've updated my graphics card drivers and even mouse drivers.
It seems to be something with waking the computer with the mouse (a USB mouse).
Waking it by pushing the power button doesn't seem to result in the same problem (at least of the computer going to sleep after 2 minutes of idle).
But I don't find that to be a solution, as it shouldn't matter how you wake the machine.
Have you typed sleep in the taskbar and selected when the computer sleeps? You should be able to set when the monitor turns off and when the hard drive sleeps. You may also check under power plans, advanced settings. There are a lot of settings there including monitor and hard drive sleep.
Power Plan Settings - Change in Windows 10
I've checked every setting I know of (system power and sleep settings, every power plan listed, even the advacned power settings) , I've updated my bios to the latest version, I've updated my graphics card drivers and even mouse drivers.
I even reset my power settings to the default settings and then reset them to my preferences. Same going to sleep after 2 minutes happens.
To clarify, the laptop goes to sleep after 2 minutes of being idle, even though all my power settings (whether the laptop is on battery or plugged in) are set to a longer time (15 minutes). No matter what I change the power settings to for sleep, it always goes to sleep after two minutes idle if I wake it after the first time with my mouse.
