Lenovo Settings Blue Light reduction Mode (Night Light) Stopped Working

Question: Lenovo Settings Blue Light reduction Mode (Night Light) Stopped Working

I have been using the Blue Light Reduction feature of the Lenovo Settings app for months and it is really useful in cutting down blue light at night and it makes it easier to sleep at night after working on my computer. Looks like there was a recent software update and I no longer see any option to enable the Blue Light Reduction feature in the Lenovo Settings utility. Has anyone else experienced this? How can I fix this and reenable Blue Light Reduction in the Lenovo Settings app?

Preferred Solution: Lenovo Settings Blue Light reduction Mode (Night Light) Stopped Working

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Alright, so I just got Windows 10 today, and the automatic blue light is really bothering me. I looked everywhere for a way to turn it off, but where ever I looked I found nothing. It seems that no setting to change the blue light filter exists on my computer. Windows installer says I'm up to date, so I assume this is the newest version. If I had to guess anything some app I deleted may have caused this, but I don't think a system setting would be related to an app. Has anyone had this problem before?

Answer:No Access to Night Light/Blue Light Filter Options

What blue light? The camera or the actual desktop hue?

By reducing the blue light emitted by your screen, the Night light feature helps you sleep better. With Night light, when you?re working late, your brain is better ready to power down for a good night?s sleep. Smartphone users love this feature and now, it?s coming to Windows 10 with the Creators Update.

Here?s how to get started with Night light:


Go to Settings (or Windows key + I), click on System, and, under Display, click to turn Night light on or off. You can also customize the color temperature or schedule by clicking ?Night light settings.?

Have a great week!

My laptop is Thinkpad W530. The system is windows 10 home edition build 14393.693.
I set up my screen by using Blue Light Reduction (BLR). Now everyday after 9pm, the screen goes into blue light redution model. However, I want to revert it back to normal. The interesting thing comes that I cannot find way to. No BLR button in quick action. No BLR shows up in settings-display.

Here comes questions:
1) How could I get it before? I remember it bubble up before to let me set up.
2) How could I revert the system back to normal if I cannot do the same steps as instruction in my laptop as link below:

Blue Light Reduction - Turn On or Off in Windows 10

3) Is that I can only wait the system updated to like build 15007? Where I can download 15007?

Answer:Blue Light Reduction cannot be turned off

Hello Jinchi, and welcome to Ten Forums.

If you like, you can download and merge the .reg file below to restore blue light settings back to default. I didn't include it in the tutorial since these are binary values in the registry that would vary depending on what blue light setting you had set. Since you want default, this will work just fine though.

It's in the insider builds I wonder how this will play with AMD or Nvidia presets I suppose you have to turn it on and turn it off when gaming unless it snaps back to defaults when you goto desktop.

Source: Report: Windows 10 Adding Blue Light Reduction Option

Microsoft appears to be the latest tech giant joining the fight against the gadget blue light that keeps you awake at night.

The software giant yesterday released a new preview build of Windows 10, which contains references to a f.lux-like feature supposedly intended to limit exposure to blue light before bedtime and help you sleep better. Microsoft itself hasn't made any announcements about this, but a Twitter user by the name of "Core" dug into build 14915 and spotted references to the so-called "BlueLightReduction" feature, as was first reported by WinBeta.

Read more: Report: Windows 10 Adding Blue Light Reduction Option

I'm a massive fan of f.lux, I discovered it two years ago when I noticed my quality of sleep wasn't the best, ever since using f.lux, it's made a huge difference to my sleep for the better.

Feel free to give it a try! Let me know how it goes: f.lux

I can't never use a device without it now (Twilight Pro user on Android as well).

Hello I was using the night mode option available on Lenovo Settings, which then had a option to turn it on or off. After Windows 10 updated, Windows now has a night mode option, but the Lenovo Settings one is still working and I can't deactivate it because there is no longer a option. At night, the screen become so red all the black parts on the screen look like blood.  Removing Lenovo Settings solve this, but I need the configurations available on Lenovo Settings, so I can't uninstall it.  Is there a way to deactivate the Lenovo Settings night mode after this update, knowing there is no longer the toggle option in the interface? A configuration file or registry I should remove or a command I should use? Thank you.

Hey guys,

I just got this HP windows 10 laptop, and I tried to enable the night light function to help filter the blue light to protect my eyes from getting sore. I followed every steps online, "setting-display-night light mode"..but I reached to the "customize your display" instead of "display", and there's no such a thing called "night light"(pic shown as below). I would appreciate if you can help me with this problem, bring me back to the normal display setting to get my favourite night light turned on. Thank you!

It's under Settings>System. Click the Action Center bottom right, and click All Settings. Click System.

Is anyone having problems with the Night light feature with the Windows 10 Creators Update?

My Desktop PC is having an issue with it to where it wouldn't turn on last night automatically. So I had to manually turn it on. This morning, Settings and the Action Center says it's turned off when the screen of the computer looks like it is turned on. My Night light on all of my computers are supposed to turn on from Sunset to Sunrise.

I will search for a solution to the problem online, but for now I am sure there aren't many solutions available since the Creators Update is so new.

Thanks!

Answer:Night light feature not working correctly on Desktop PC

Update: The screen on the Desktop PC has now returned to it's regular color.

I'm new and not sure if this fits in this category.

I have a Hunter ceiling fan/3 lights. It's almost three years old. My wife flipped the wall switch the lights came on, then off. The fan still works. These are the facts and what I've done so far.
All three lights don't work. The bulbs do work on other lights when tried.
I have one wall switch for the entire fan/light
I ordered and installed a new light kit and the lights still don't work.
The fan works fine.
I tested the wire harness from the ceiling and have 120 volts.
I've not tried looking at the wall switch (only one switch for both) because the fan works.
I'm not sure where to go now.

dell xps m2010 wont start up ,blue power light and bluetooth light stay on,i have been searching posts in other forums as well as this one and i thought i`d narrowed it down to the graphics card,i was right to an effect,my approach was to take the xps apart following dells website documents,while i had the top (dvd drive) off ,i noticed that the graphics card screws were really loose (this was my first job)...i tightened these.The top(dvd drive ) i re-connected ,but propped it up at an angle so i could still see motherboard and parts,(warning!be carefull!!)electric!! ...attached power cable and pressed power button after half a dozen times pressing this it came to life.I noticed my fans were working and thought this might not be my motherboard after all ,no overheating happening...then it froze on windows xp ??it was a start !another 6 to ten times pressing power button it worked again this time not freezing.went into bluetooth with usb mouse and paired keyboard ,made system restore point and restarted .It took maybe 4 times with it being glitchy(freezing ..not powering up) ,but when it does load xp without freezing try restarting windows xp and then it eventually finds its feet!!!my xps 2010 is running ok now.jimb

My laptop was working fine yesterday, charging and powering on an off normally. It updated without my telling it to. When it was complete (since it said don't turn computer off until finished) I either just shut the lid or I shut it down when it was done. This morning when I wake up and try to turn it on it won't power up. Then I noticed that the power button was blinking, like it is in sleep mode, tried pressing 10 times then holding down power button for 30-60 seconds and still nothing. Next I saw that although the power is plugged in the battery light won't come on. I don't know if it is charging (it could be dead). I tried a bunch of different outlets and that isn't the issue. I also listened to the computer and there is a very soft high pichted noise that dissapears if you unplug it, and that when you hit the power button and it starts blinking, the sounds changes fom high to lower pitch and back again over and over. But no other sounds or fans kicking on or drive spinning. I am pretty sure it isn't the power cord but have no way of checking. And I can't remove the battery without voiding the warrenty. Anyone have any advice, besides calling to have Lenovo send me a box to send it back to Lenovo since it is only 4 months old and still under warrenty?

Answer:Lenovo Edge 15 laptop 80K9 battery light won't come on, power light blinks

Suggest you eliminate problem 1. Do you have spare power supply unit? Worth trying that first. Your battery may be in sleep mode and won't wake up as battery is drained and hence needs charging. 2. You can go to local retailer and suspect a good one (John Lewis) will let you charge it for 30 mins. Ideally go back to person you bought it from. 3. Once you are in use restore to go back to last working point. I have to telll you the support from Lenovo and Microsoft was very very very disappointing. I tried to even return the PC and swop for HP as mine is only 2 months old. However, the answer was send back to Lenovo. Hope you find a way to get it charged

Hi Wacky78900,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to hear that your Y500 Laptop is not turning ON after playing game and turning OFF manually, I suggest you to perform the Flee-Power and check the issue. Below are the steps to check and resolve the issue:
 

Remove the battery and any other peripheral device connected to the computer.
Hold the power button for 10-15 seconds and then connect only the AC Adapter and try to turn ON the computer.

If the issue persists even after performing the Flee-Power and as the computer is in warranty, I would Strongly Suggest Calling Technical Support for Assistance. Click here to open a link where you can select the country and get the exact contact support number. I?m sure they will be a great help.
 
Do post us back for further queries.
 
Best Regards

Answer:blue light pwr and green light for what ?

It sounds like your green light is the Hard Drive activity LED and if it is on constantly rather than flashing at irregular intervals then I suspect you have a hard drive problem.No amount of inserting your recovery disk will fix a hardware problem.You should download a hard drive diagnostic tool and run some tests.Goin' Fishin' (Some day)

Hello, I bought this laptop about 4 months ago. After a while the trackpoint started to have problems when the surface underneath the laptop was uneven, so I sent the laptop for repair in US and I believe they changed the motherboard. A week or so after I got the laptop back the issue happened again, but it didn't happen as often and I was about to leave for Moscow so I forgot about it. Fast forward two happy months of use, last week for no apparent reason the trackpoint AND touchpad stopped working (previously the touchpad worked). I've tried reinstalling drivers and all sorts of software tricks (including looking into bios and updating it). I have two questions:1. Weirdly enough, there isn't a single option in bios about touchpad, trackpoint, or UltraNav, which makes me think the bios doesn't even see the hardware! Can someone with a working UltraNav on yoga 12 check their bios under keyboard/mouse and let me know? 2. Has anybody sent laptops for repair in Moscow? Is the quality and duration of service reasonable? Do they have depots here or only certified service providers? If need be, can they change the motherboard or would they have to send the laptop abroad? I'd rather not stay without a laptop for a month! 3. Has anybody had recurring problems like this?

Answer:Ideapad Z500 Keyboard back light - stopped working after Windows 10 upgrade

Update: I purchased a genuine second hand keyboard online fo £22.00 and the backlight is working perfectly. A good way to test the functionaility of your keyboard is to see if the light comes on during the boot-up. If it does not then it is either a loose connection or a faulty keyboard. It is worth opening up the keyboarg to see if there is a loose connection...see this video on how to do it, it very simple and will take you less than 5 minutes. https://www.youtube.com/watch?v=_lK4mKT_7gA If the connection are ok and you still do not see the back light working during the boot up, then I am afraid to say that you have a faulty keyboard. Don't waste you time like I did trying to get it to work...get a replacement!

For a couple of reasons I decided to go back to Windows 7 after a brief time with Windows 10. However, now, I can't get rid of the night light that is supposed to cut down on screen blues. I understand its purpose, however, I can't do what I want without seeing natural colors. I like to play games in the evening as a way to relax, but when that nightlight feature is on, as a hold over from 10, I can't tell one color from another! Everything is orange. I asked the same thing on the Windows 7 forum but was referred to you folks. What do I need to do to get rid of the pinky/orange???

Answer:Had Windows 10; Back to 7 But Can't Get Rid of Night Light!

I wasn't able to find anything with a quick search on the net, but found this:
Blue Light Filter Software For Windows 7, 8, 8.1, 10 | TechnoClever

A 3rd party software, I think, for the night light thing. See if you can fix the colors with that when the night light settings turn on.

I wouldn't rely on my response as a complete solution for this. Hopefully someone else knows how to fix the issue itself. But my post can maybe used as a temporary solution for the time being.. if it applies.

Hi all,
I have a weird problem with my Precision 5520. Ever since I've updated Windows 10 to 1709, I get weird colours when using Night Light.  The following images illustrate this:

With Night Light - notice how distorted the blues look (should be redder)
I've already opened a support ticket with Dell, but has anyone else had this problem?
Thanks, jafico1

Answer:Precision 5520 - distorted colours when using Night Light

Could be a bug in Win10 1709 (there have been a few big ones already reported), but try adjusting the warmth/coolness slider. Even if you end up putting it back where it is now, ?toggling? it might change something. And then I guess make sure your graphics drivers are current. No ?competing? applications such as F.Lux, correct?

Unlike the earlier T41 models of thinkpad, the keyboard light in the T400 is almost nonfunctional due to poor design. When you turn the light on the light shines almost directly into your eyes. You have to tild the screen to an angle that is almost unviewable for the light to actually illuminate the keyboard. Has lenovo come up with a parts fix for this because it's really obnoxious and an obvious design oversight. Thanks

Hi I've had the Dell XPS 8700 for over a year now and it's an excellent Desktop.
I've recently moved my tower to a new location and notice there is a solid orange light on all the time inside the PC, I believe it's on the motherboard... should I be worried this is on all the time? It's just I've never noticed it before.
Also on the back of the PC there is a solid green light, I'm guessing this is to just tell me the PC has Power.
I tried a google search but everyone with the orange light seems to have PC issues, my pc is working fine as far as I can tell.

Answer:Dell XPS 8700 Orange Light inside and Green Light on Back

LED on the motherboard will be on as long as the PC is plugged into a working outlet. It's perfectly normal and nothing to worry about.
If you unplug the PC from the wall and press/hold the power button for ~15 sec, that LED will go off. Again, perfectly normal...
Green LED says there's power to the PSU.

I will turn it on and after a minute or two the monitor goes to power save mode and the hard disk light goes from off/blinking to solid on and the power light stays on.

I have reinstalled the operating system and i thought that fixed it. I had SP 1 i installed all of my updates and SP2 and it starting to do it again (it will do it in SP1 but not nearly as often or when i run a flash heavy program: PSP Video or even the Scion website).

It will not do it at all in BIOS as i did every test on the diagnostics page for my hard drive (all pass) though if it turns off it usually turns on and runs dskchk and it wont stay on for that

In safe mode it is also fine it will not turn off once

I dont know what i did last as it was fine then i was gone for a month and I had it unplugged etc., came back hooked it up and it started doing it after a little while

I have taken a can of air to every inch, switched the Flat cord going to the HDD from the Motherboard.

All fans run fine

Thats all i can think of right now ask me anything else you need to know

I'll give this forum a couple of days/a week maybe then i'll take it to a local shop to diagnose it

Much thanks to anyone who has any idea's

Hi. Tonight I had a problem with my laptop. It was in sleeping mode, and when I open the lid there were no mouse function and no touch screen function. So the only thing I could do was to press the power button for 3 seconds to turn it off, but it didn't completely, because the screen turn off, but the power button light is blinking just like when it is on sleep mode, and I'm not sure if the hard drive light was on, off or blinking before this, but now is blinking. I press the power button and nothing happen, I press it for 3 seconds and nothing happen. I even did the HDMI connection to another monitor, but both monitors don't show anything, not even recognize that something is connected to the HDMI port in the new monitor. There is no sound, nothing, just the 2 blinking lights. What should I do? Thanks PS: I'm not sure if it's Windows 10 32-bit or 64-bit. It was upgraded from Windows 8

Hello,
Was experiencing general issues with my windows profile after windows updates last patch Tuesday so I initiated a system restore and let it run today.  After completion laptop turned off (instead of rebooting?)

Pressing the power button: Power button turns white (on) for ~30 seconds, then laptop turns off (indicated by power button light)
no fans
no screen (back-light or otherwise)
no POST codes - beep codes or light codes.  
no other visible activity

During that period nothing else happens, unless I press the power button again. If I do this
The fans spin up momentarily
The system then powers off (as indicated by the white power light)


I've tried:

Disconnect power/battery and hold power button (60 seconds)
Power system on with just battery
Power system on with just wall power
Remove mSATA HD and repeat the above
Disconnect video connector and repeat above
Remove mPCI WiFi module and repeat above
Completely disassemble and remove CMOS battery (tested at 3.1 VDC) for 60 seconds, reassemble and repeat above

All with no change in behavior

I am able to get a light code 2 Amber / 3 White if I remove the RAM module (as expected)
D + PWR diagnostics cycle successfully through a range of colors then nothing

Laptop is 2 months out of warranty.  Any help debugging the issue is appreciated!

Those buttons are controlled by ?Toshiba Button Support? utility and this utility is part of Value Added Package. To be honest I don't know if there is some way to enable/disable the buttons functionality but if you want you can try to do follow:

Remove preinstalled VAP from the system (Control Panel > Programs and Features), restart the notebook and install latest VAP for your notebook model listed on Toshiba Support page under http://eu.computers.toshiba-europe.com > Support & Downloads.

I have acquired a friends laptop Dell Inspiron 2200. Upon hitting the power button, It will light the cylinder, which stays lit, It lights ALock, which flasshes, cycles for about ten seconds and then powers down. The screen never tries to do anything. I connected it to my VGA and still nothing.

I searched and found a few references to booting without the battery installed. No change.

Where else should I look?

I was told that the laptop had a heat related failure at one point, but that they installed and ran a fan control and the laptop would function normally after that point. Could it be an issue with the fan causing the power down?

I'm not sure if he is interested in spending the money on a new board, or if at all.

Thanks for the help.
 

Answer:Dell With Cylinder Light, Alock Light, then dies?

Warning! I'm by far more of a "I need help" poster than a "let me help!" poster.....but having said that:

I'm fighting the same thing with my Inspiron 1520. Somebody here said to check the BIOS battery. I did, and it tested bad. So, maybe check that?

I can't tell you if it worked, because I haven't been able to simply change said battery. I had to order a new BIOS battery assembly because the Delltards created some method of attaching the leads directly to the battery. Sigh. So their "happy" customers get to pay $20 plus shipping for a $3 battery.

The FL inverter is a tiny part hidden in the display frame.

alright, I just got this inspiron 6000 from my sister that didnt work. she said nothing would happen at all. well it turned out the power light would go on, caps lock light blink for a few seconds and it would turn off. somehow the memory wasnt in the slot very well. bam, got it working, dumped all her pics and crap to a external hdd, and wanted to wipe it all out and start over. she is sending me a xp disc, but for now I just figured Id go back to 2k cuz I have that disc and when I get the disc go back to xp.

anyways, I couldnt figure out how to format the drive, because obviously xp was running off of it. anyways, I kept trying all the del - f2 - f8 - f12 to get a dos prompt before windos would load but I couldnt. so I figured Id just put the 2k disc in because I thought I remember that it formats it right before it installs. but it asked me where to install and the disk was partitioned and I wanted one drive letter so I cancelled the install, before it was actually installing though, said f3 to quit and I hit f3. now when I try to power it up, the power light comes on, the hdd light comes on for maybe 1-2 seconds max, then the cd drive light comes on and it spins up, then stops, and the screen just stays black, never did anything either. just black the whole time.

also, just checked, and its nothing to do with the lcd. I just hooked up my monitor, and my monitor tells me when there is no signal, and it just stayed black, then when it was unplugged from the laptop that is when it said no signal.

This just started happening recently. The power indicator light (near the power plug) does not turn on and Windows does not recognize when the adapter is plugged in; the power icon and cusomized power saving "on battery" behavior reflect that. HOWEVER, the battery does charge. The "lightning bolt" charging light on the front between HDD and system power lights comes on and the battery recharges if not at 100%. Any thoughts on how to troubleshoot this? Is it more likely a Windows or hardware problem? The BIOS does not have the power adapter test mentioned here, and I could not find the software download for the Smart Adapter functionality (this laptop was installed with clean, non-OEM OS, so any OEM software had to be added manually). Thanks in advance,Kyle

Hello! I have been having this problem for about a week now, ever since I set my old computer back up in my room. The problem started when I left my computer alone for a while when I went out (the computer was working fine and I had just finished transfering pictures to my computer from my camera). I came back and the power light on the front if the case was on, but the battery light was off. The monitor had also gone into sleep mode. I turned off the computer since I knew whatever I was going had already been saved and exited out of, unplugged everything (including the monitor and PC/Monitor cable) and plugged it back in and turned them on. The monitor goes straight to power saving mode (sleep mode). The PC is definitely receiving power, the keyboard's caps and num lock keys flash, the wireless mouse's light flashes, the pc fans turn on, and both of the power and battery lights turn on. But, after a second, the battery light turns off, and the only light I can see through it is the power indicator's light bleeding through. The strange thing is, I've been able to get it to work before, about 2 times actually. Both of those successful boots happened either when I ignored the thing for so long or left it unplugged over night, but had already forgot it didn't work last time. But it did those times. So I tried to leave it unplugged all last night. Just woke up, and... still nothing. I really need to to get those pictures to my mom, so if someone could ple... Read more

Powering off and re-powering rarely helps it just have to be left alone and comes on whenever if ever.. Thanks for help

Answer:The power light keeps blinking and the harddrive light is on

Try a new signal cable from PC to monitor.If no change, try a new graphics card.If still no change, test the hard drive with "Seagate SeaTools for DOS".Click the "Download" tab here: http://www.seagate.com/support/down...The download is an ISO file, so you'll also need to install "IMGBurn" from here:http://filehippo.com/download_imgburn/Use IMGBurn to create a CD from the ISO file, then boot your faulty computer from it. The testing program will open. Select the hard drive and test it. If it fails the test you need to replace the hard drive.If hard drive passes the test it's okay, so test the RAM modules with "Memtest86" which is also an ISO file, so you need to create a CD from that too:http://www.memtest.org/

This is actually a feature I have only recently come across and it dawned on me that I am actually missing this feature in my installation of Windows 10; the feature in question is "Night Light", basically f.lux, but actually a part of the Windows 10 operating system. My Windows 10 installation appears to be completely up to date, yet I do not have this feature. I believe that perhaps it may be the result of group policy tampering on my PC as I did tamper with a bit for privacy during my initial installation... But I can't find anything pertaining to this particular feature. If someone can help me out it'd be greatly appreciated. Thanks.

Answer:"Night Light" Feature missing on 1607

Hello Nathan,

The "Blue Light" reduction feature was first introduced in Windows 10 build 15002. It was renamed to "Night Light" in build 15019.

It sounds like you don't have the latest Windows 10 Insider build installed to have this feature available yet

hows it going everyone!? just want to start out by saying I'm a newbie when it comes to computers so i really hoping I'm at the right spot. my laptop died on me recently so i hopped back on my desktop and it was acting really weird it would get some blue pixel lines going any where from half an inch to a few inches long through the screen and it would get to the point where i would freeze and restart/blue screen or anything that was open would flash a bunch of random colors or wouldn't let me access anything on it or it would say something like this program has been disable... then freeze. i use every program out there from spy bot, spy doc, melware bytes to combo fix and i ran them all in till they all said my pc was clean but the problem keep happening i was only able to use my comp in safe made. when i was in safe mode i didn't see a single dark/light blue pixel lines which was really nice then my buddy gave me an extra copy of windows 7 so i reformatted and sadly the lines are still there but its not freezing or glitching out like it did and windows is up to date and I'm stumped i don't know if its a video card problem or a super virus... HELP ME PLEASE!! i might have screwed up on the reformatting because i seen a few programs on my comp still from before like mirc and perfect world on it so i just might reformat it again if we cant figure out the problem.
Thanks

Question: Blue light

We have a Toshiba laptop P200. Upon shutting down the blue power button is still on and won't go out, even after unplugging the machine. Now it won't boot up, all we have is a blank creen and the blue light.

Answer:Blue light

Any ideas where the blue light is? (what it may represent)What were you doing before this? (hardware changes, downloads, installations, software changes, etc....)When you press the power button, exactly what happens?

My system just upgrades to windows 10 version 1607.  It works fine except the mute light and wlan indicator light both stay on.  The keys work, but the lights stay on, regardless of whether sound is muted or airplane mode is on.   CAPS indicator light works fine.  Both lights stay on when f5 is pressed turning off keyboard backlight.  System is Spectre 13t - 3000, model E5E03AV.  I assume this is a bios setting, but don't know how to fix.
