Lenovo P51 - Unable to Adjust Brighness in Windows 10 (Build 1803)

Q: Lenovo P51 - Unable to Adjust Brighness in Windows 10 (Build 1803)

Hi, I have just installed Windows 10 (Build 1803) and I have ran Leanovo Vantage on here to update all drivers and firmware, however for some reason I cannot increase (or decrease) the brightness of the laptop at all. I did some research into this and I saw this has been an issues before on some other models but I couldn't seem to find anything related to the P51. The screen is visable, however I would say it is currently fixed at around 40-50% brightness. Has anybody come across this before and is there anything I can try to do to fix this? Regards, Jonathan.

It's worked out well for many of us in the past.

Found the answer to what I was seeking! If you don't want things like Cortona to remember your searches, or your Microsoft Account activities, do the following:

1.) In the search box type "Privacy" (No quotes)
2.) In The General Settings go to Privacy Settings
3.) Go to Activity History, and there are a lot of things you can clear and uncheck about the information and searches on your computer. Very helpful!

Windows still uses Microsoft made "Generic Mobile Broadband" driver, even after installing the Fibocom L830-EB Wireless WAN Dreiver For Windows 10 (Versio 1709 or later).  This ends in only giving a 50 mbps LTE connection even if the location, sim card and subscription gives 300 mps connection possibillities.   Windows only sees the generic driver, even if I manually try to choose a driver for this. No Fibocom drivers are found in the list.  Is there something that got broken during the latest 1803 installation? Has anyone else noticed this?

Hello guys: I have Windows 10 ver 1709 on my laptop which is working great. I have tried instaling Windows 10 ver 1803 two times already (with one month gap) on my laptop without success. When it finishes installing and reboots the computer, it never recovers from it. I see a black screen where mouse is enabled and nothing else. Both times, I have reverted back to version 1709. I have checked Lenovo's portal for my computer and I dont see any software/driver upgrades that I need that were released in the last 180 days. Can anyone tell me if I need to upgrade any driver before trying the upgrade? I have the following specs: Product: 20378BIOS: 9ECN43WW(V3.03)

I have a Lenovo Thinkpad P50 laptop that I have been using with an external Dell Ultra HD 4K Monitor P2415Q running with a resolution of 3840x2160 @ 60HZ using DisplayPort.  Initially the laptop was running Windows 10 version 1607. Under this version of Windows 10 the external display worked properly regardless if the BIOS ?Graphics Device? setting was set to ?Hybrid  Graphics? or ?Discrete Graphics.? Unfortunately, since Windows 10 now forces updates when new versions are released I was not able to stay on this version. When Windows 10 updated itself to version 1709 using the external monitor described above stopped working. When the external monitor was plugged in (both DisplayPort and HDMI) it would briefly display an image and then go black. The Nvidia display adapter would then show as not working in the Device Manager. I spent  a significant amount of time working with Lenovo technical support uninstalling and re-installing drivers etc. Nothing worked, I was still not able to use the external monitor. After some further experimenting I found that I could get the external monitor to work if I set the BIOS ?Graphics Device? setting to ?Discrete Graphics.? It would not work with the BIOS set to ?Hybrid Graphics.? Last week Windows updated itself to version 1803 and the external display problems have returned with some additional incorrect behaviors. As I stated in the previous paragraph under version 1709 the external monito... Read more

Speaking with a Microsoft tech. via the live chat, he said that Lenovo has not released the drivers necessary to run version 1803, there I continue to get errors.

After hard shutdown with power key 2, 3 times its showing message that 'Attemptiing Automatic repair' then 'recovery to previous installed version' but quickly again restarting back in loop.  I tried following other methods:1. Tried entering to setup by pressing F2 - no luck2. Created bootable USB and started laptop and pressed F12 continuosly - no luck3. Removed battery and pressed power button for a while and restarted hoping to enter setup - didnt helped4. used One touch recovery key next to power button while system is off hoping after system on takes me to sestup page - didnt helped If I could atleast enter setup or boot will try to solve, I Sincerely request memebers here to help me solving this issue. Thanks

I am having this problem from past 3-4 days I am unable to adjust my laptop's brightness. The functions keys for brightness won't work. I also tried changing the power settings to high performance and balanced, that also doesn't changes the brightness.
I also tried manually adjusting the screen brightness. The slider moves but the brightness is not changing.

I am using IntelR (HD) Graphics family.
I tried changing it back to Microsoft basic display adapter but that also didn't help.

I got windows 8.1 installed from the factory itself and everything was working fine until past few days.

Any suggestions??

P.S. => I am using a Lenovo G50 series laptop

A:Unable to adjust brightness in my windows 8.1

First off, figure out whether or not your laptop has an ALS (Ambient Light Sensor) which will automatically adjust the brightness (if all goes well). Usually it won't override a manual setting, but it's kind of up to the developer which one takes precedence. As for the keys not working, you probably removed (or didn't install after a Windows reinstall) the helper software that controls these functions.

Thank you forum! Much gratitude here for your selfless service!!

I am not very tech savvy but I am usually able to solve my own problems. My cat jumped on my keyboard, my display went dim and I could not adjust it ! I am able to move the brightness bar up and down but nothing happens. First, I tried a system restore but that did not work. I went back about a month which was the earliest restore point I had. Then I went to device driver and looked to see if my driver was functioning properly. I was told it was updated and functioning properly. I tried clicking on the windows generic monitor driver also as advised which did nothing. I went to the device driver on the pc and updated from that which also did not work. I am using windows 10.

Hello,Laptop which is facing the problem, is Lenovo Z500.Windows 10.A problem that is known, but I can not deal with it.I installed 5 different drivers for the integrated graphics card, changed the parameter in the register FeatureTestControl parameter to FFFF, I installed various energy management. I changed the HD4000 driver to the basic one from Microsoft.Nothing helps - when clicking the dash / dimming, a bar appears, which moves as it should, but the screen is still the same dark.As I enter the settings -> screen, and there I set the slider, strange things happen, the screen goes self-darkening, dims itself, literally as if the laptop had a light intensity sensor ..The BIOS can be used to light up the screen, it shines as it should, it does not get dark, etc. The matrix is okay.Anyone have any suggestions on what you can do here?Actually, for me, brightness can be 100% all the time, but the way with FFFF in the registry does not help.

A new setting you can put in your system IF you are running 1803 (OS build 17134.48) is the "Ultimate Performance" plan. Open up powershell (as administrator) and type the command:

powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

Go into settings, system, power and sleep, select "additional power settings" under "related settings" and you now should have "Ultimate Performance" as a selection. This will only work if running this version of windows. Type "winver" in the search box to check what version you are running, first. This is for "higher end PCs"

I've noticed, today, that I'm suddenly unable to adjust my screen brightness. I have read half a dozen threads reporting the same problem; I tried all the solutions therein (from updating the driver and reverting to the most basic one to manually changing power configurations) and nothing worked. Unlike the vast majority of users who had this problem, this hasn't happened following an update to windows 8.1 (which I did several months ago -- and the adjust was working fine after that).

This might give you a hint:

* As I try to adjust it using the fn key (as I had always done previously), brightness goes up or down just one level -- and that just 'cosmetically', as in fact nothing changes. The indicator gets stuck approximately in the middle of the bar, unable to reach the extremes.

* There is more: on power management, I chose the lowest possible level of brightness when working on battery, just to see what would happen. I then disconnected my laptop from main power, and... the brightness indicator did go down to the lowest level, YET brightness remained unaltered in fact.

Anyone, please??

Hey Guys,

I have a local account as a default on my machine. I disabled the Timeline feature, no problem. But, no matter what build 1803 has this "Pick Up Where You Left Off" as a part of Cortona/Search and it shows a list of Recent activity things you do on your computer. Even non-related Microsoft tasks. I have attached an image to illustrate. Is there any way to turn this off, and just use Cortona like the search in previous search builds?

Apparently, turning off timeline doesn't make a difference to Cortona.

Hey everyone,

Thanks in advance for any help.

My Windows Vista isn't letting me adjust my power settings.

Here is what the problem:

1. I click the battery icon in the bottom right of the start bar. Then I click "More Power Options"

2. On the left panel of Power Options window, I click "Choose when to turn off the display"

My computer tells me "Your power plan information isn't available" with a red X next to it.

The same thing happens when I try to adjust any other power setting as well.

3. I click on the "Why can't Windows retrieve this information?" and it says stuff about my system administrator making changes, and that doesn't apply to me. I am the only user of the computer and my account is the administrator. I've never tinkered with any of these files to my memory.

It also says "Some of your power management settings, or the registry keys that are associated with those settings, have been deleted or corrupted. For more information, contact your system administrator." But I am the only administrator of this computer and the nice people at Microsoft never instructed me about this when I bought my computer.

I've done a SFC scan and it said "Windows Resource Protection did not find any integrity violations."

I've also tried searching for an answer on other forums but I either don't understand the solutions, which usually involve registry edits...or the problems I've found aren't exactly on target and ... Read more

I ordered an HP EliteOne 800 G2 23" All-in-One PC with a Recline Stand.  All instructions I have seen so far are inconsistent with the stand I received.  My stand has a lollipop-shaped key in the base that apparently needs to be removed so that the stand can be adjusted.  However I am unable to remove the key with normal exertion and am afraid to apply more force until I am sure of that I am doing.  The key seems to be slightly crooked so I am wondering if perhaps it was damaged in packing or shipping.  If anyone could help with any information about the Recline Stand, I would appreciate if very much.  So far I have found very little information, and nothing about the key, either in the box on on-line. Thank you,Ken Traynham
