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.)

Well the title says it all... I updated Windows and brightness is now locked on minimum. Even if I press F12 or go into the settings, the brightness bar will fill but the screen won't show any changes at all. Sorry if I mispelled anything but I can barely see on this screen due to this issue. Can someone please enlighten me? Literally.

Hello there, I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).I searched online and I tried:- updating/reinstalling/rolling back display drivers- resetting pc (reinstalling windows)- many other little repairs College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

I can't adjust brightness on my Thinkpad X1 Yoga. I've run all the latest driver updates, used lenovo companion and everything is up to date, including bios. No matter what I do the brightness will neither increase or decrease.
 
It's stuck on full brightness, so it's not too bad, and I'd be loathe to send it in for repair and lose a week or work to get it fixed. Is there anything anyone can suggest that might help software wise?
 
Thanks!

For months now my laptop has been logging me out after I just logged in to use it. Once I log back in after this I find that I can't adjust my brightness in any way. Whether it be through the device settings or by using the brightness F keys. There is also a strange square that shows up that often changes colors and location on my screen (2nd image). When i go into the device manager this is what I see (an indicator that something is wrong with the display adapters): I have tried uninstalling the Intel(R) HD Graphics Family and re-installing it and that fixes the problem temporarily, but when I shut off my computer and go to use it the next time the same problem persists. I've gone into the Lenovo Vantage and run Health and Support tests, but it doesn't detect anything. I've downloaded updates recommended for my system and nothing seems to work. This problem is really starting to irritate me and I would like to try and fix it before investing in a new laptop. This laptop is only 4 or 5 years old. I would greatly appreciate any other tips or advice!

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.

Using the laptop on battery, when I press on F11-12, the brightness meter is shown on the upper left like usual, but it won't move up or down.  Yet I think it's strange that all other places I can adjust brightness are fine, and especially strange that everything is working totally fine on AC power.
I tried uninstalling the Generic PnP monitor and reinstalling, but to no results.  Also, both my power settings on battery and on power indicate no adaptive brightness.

Beginning today, I opened my laptop from sleep and noticed the display was at its lowest brightness setting. I then tried to restart it to see if that would solve it, no luck. I did some googling and found out it could be a problem with the graphics driver. I then disabled it and enabled it. Now the brightness is at its max settings.

The function (FN) + F4, F5 (the keys to adjust the brightness settings) do nothing. The brightness status will show up on the screen and only change 1 or 2 notches.

I then realized I should have a way to adjust the brightness via the Power Settings in the Control Panel. I even confirmed this with a friend. I should have the sliders to adjust the brightness but I do not. It's very strange.

This is the screenshot from my friend:

Hey all,  I recently bought a Lenovo Yoga 720 15-inch 4k and love it! Unfortunately, it was stolen in Mexico and I had to buy a new one upon returning to the States.  One of the first things I changed when I got my first 720 was the screen brightness. I switched off the "Adaptive Brightness" setting in System > Display settings and that seemed to make my screen nice and bright white.  Now, on my second computer, even at 100% brightness and with the Adaptive Brightness switched off, the screen looks much dimmer and not as crisp white.  Any thoughts on what might be going on? Thanks! Dave

The brightness repeatedly increases and decreases by about 10-20% which is so annoying that in the meantime, I had to disable the automatic brightness function in Windows.  I guess this is due to the ambient light sensor location but I have not been able to figure out a solution.  Any tips?

Ok I've had vista for a long time, but I switched over to XP and everything is perfect except from one small detail that is kinda big for me. I can't adjust the brightness in my laptopIn vista all I did was press fn left/right arrows to adjust it. And from what I know this is the way you do it in most laptopsNow in this XP I had to install all drivers. Specifically from this page http://www.laptop-software.com/acer-softwa...5738zg-drivers/when I install the graphics driver, VGA intel driver for vista is the one that's used for my computer from that list, the brightness just goes to the max apparently and I can't use fn arrows to adjust it. I CAN use fn arrows up and down to adjust the volume so there is definitely something fishy here. If I uninstall the driver I can use fn to adjust the brightness normally so I know the problem is when I install the driverthis brightness is driving me crazy! the driver bring something called Intel Graphic Media Accelerator which has an option for brightness, but it seems as if that's a different type of brightness cause it just makes the screen duller. You can actually still see a lot of brightness coming out from the computer but the screen is very dull. And it still damages my eyesany help?
