Windows 10: Cannot stop Night Light from turning on despite settings

Hi - My Windows 10 Acer laptop insists on turning on Night Light during certain evening hours. On my Night Light settings I have "Schedule" set to OFF. However in the evening my screen is obviously missing blue (even confirmed this with a calibration meter). If I go to the tile and turn off Night Light, the screen brightness and I can see it turned it off, and then a few seconds later the Night Light turns right back on! I have repeated this many times and it only turns off for a few seconds - if in these evening hours. Even if I click the Turn On/Off Now button in the settings, it will turn off and then a few seconds later turn right back on.

The only way so far I have been able to get it to go off in the evening hours is to change my system time so that the computer thinks it is daytime. Then the Night Light turns off on its own and stays off. For instance at 10pm I tell it to manually let me change the time and set it to 12pm and then the night light goes off and stays off. Until the "evening" hours come along and it turns right back on.

I am really confused as to where it is getting this bedtime schedule from, and why it insists on following the schedule. Perhaps there are settings other than the Windows settings or perhaps there is some other app installed that is doing this? It is one of my kids laptops that I took over, so maybe the installed some program. I do know that Windows pesters me with messages like "Time to get to bed" and "You only have 5 hours before you have to wake up" type of messages. Can someone please let me know how to turn those off too?

In case it matters this is an Acer laptop with an Intel HD Graphics 4600 and NVIDIA GeForce GTX 850M internal cards. I checked through the Nvidia Experience app and there are no settings related to sleep or night light.

Thank you!

Night light

Hi,

There are several reasons why you are having issues turning on or off the Night Light settings of your Windows 10 PC after the update. To troubleshoot your Night Light settings, we suggest that you apply the steps on this

Night Light Settings

Separately from the Night Light, is the brightness options also disabled? If so, I might recommend these steps to make it work again:

1) Right-click Start button, choose Device Manager

2) Find the "monitors" section in the list and expand it

3) Right-click and uninstall every item listed under the monitors section

….. note: don't accidentally go to the "display adapter section", leave that one untouched.

4) Click the "scan for hardware" button on the toolbar up top (the icon with the magnifying glass inside it)

5) Try brightness and night light settings again
