Hello, I downgraded my OS from Win 10 to Win 8. It seems like I couldn't get all the drivers updated because there aren't too many drivers available for Win 8 on the support page. The most noticeable problem to my labtop is that I cannot change the brightness of the laptop as well as the airplane mode. Whenever I press on the key F11, 12, and 6, it doesn't do anything. Is there a driver available for download online? Thanks.

I have a new Lenovo Ideapad 310-15abr, Windows 10, 64 bit, AMD with a Radeon 7 graphics card, with a display problem. When I unplug the power (so it's on battery), the screen dims. So I went to Power Options and changed the power plan both on and off battery so the screen is at 100 percent brightness. Didn't work. Tried a Custom Plan and then went back to a High Performance plan. I turned off Adaptive brightness; disabled the Sensor Monitoring service; updated the Graphic Card driver;disabled and then enabled the Graphic Card again. Turned off Lenovo's Power Options called Power Stretch and Conservation mode.  Also updated the AMD VGA driver.  Nothing works. Still dim when on battery. One thing that I have NOT triedit is changing the registry value by using Regedit command and changing the Feature Test Control. I didn't try it for two reasons. One is that I'm not sure what to reset it to (I've seen "ffff" as the setting and something else longer and more complicated). The other reason is that I am too much of a dumbie to be messing with registry values, basically. I've seen this question asked a couple of times, but no very definitive answers. People usually just tell you to change the Power and Sleep settings so the brightness is on 100% when On Battery.  So that answer is not necessary, but ANY OTHER ANSWERS would be welcome!  Thanks -- Ken

I just purchased this new laptop a couple of days ago and love it other than one thing that is annoying the crap out of me. The screen is too dim when unplugged. It is great when plugged in, but dims quite a bit when it is not. I have the brightness at 100% for both the on battery and plugged in settings so I have no idea how they vary so much. I have it set for high performance, not power saver. The battery saver is also off. I have looked all over the internet and found no useful info.

Hi Sam,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to hear that brightness functionality is not working as expected in your Z400 Laptop; I suggest you to install LEM (Lenovo Energy Management) and the latest display drivers in the computer according to the relevant OS (Operating System) installed. Below are the links to download the relevant display driver:
 

Intel Video Driver for Windows 8.1(32-bit  or  64-bit)
Nvidia Video Driver for Windows 8.1(32-bit  or  64-bit)
Lenovo Power Management for Windows 8.1(32-bit, 64-bit)

Hope this helps!!!

Hello, I recently had a downgrade from windows 8 to 7 in my Ideapad s300 (intel i3) and I noticed that display's brightness is very dimmer than when I was using windows 8.I tried almost everything, the brightness is actually adjustable, but the maximum value is still much dimmer than it was on 8, I tried both intel's latest drivers  for the intel hd 3000 graphics card and the official lenovo ones but this didn't solve the issue.I read in other topics that the problem can be solved by updating the bios.The problem is that there's no BIOS update on my support page for this model\product, and the only one I found is for the s400 model, which I am not sure it could work or either cause some serious troubles.At the moment I have almost everything installed from the lenovo support site, including vga, chipset, energy management etc.I saw another thread that suggested to upgrade the bios but there's nothing about it on the support page, apart from a link to an external download claiming its fot a s400 model, so i'm not sure.Can someone help me? What should I do? Is there an official bios update for my product? Can you be so kind to share it with me?

I am totally disappointed in Lenovo's customer support. My lenovo 710s was bought less than 1 year ago (as of 10/6/2017, when I sent it in for repairs) and had 2 years warranty (1+1 year of extended warranty). I sent my laptop for repair due to a white spot issue on the monitor, affecting viewing of webpages and videos. However, the laptop was returned after 3 weeks without any fixes/repairs, as Lenovo claimed that it was a cosmetic issue. I wrote a message on their customer care website on 3/7/2017. However, they ignored me and there was no reply to date.  I thought Lenovo is a reliable and popular brand. However, it turned out to be a horrible decision, much to my dismay!

So everything has been working fine on my laptop until about 10:30PM EST tonight. I bought it new in August 2011.
Specs:
 
OS: Windows 7 Home Premium
CPU: Intel Core i7-2630QM @ 2.00 GHz
RAM: 8 GB
HD: 750 GB
BIOS: 45CN36WW
 
It's always been a fine machine with NO problems.
However, last night there were Windows 7 updates that were installed and then restarted my computer. I had not gotten a chance to check exactly what they were though. About 10:30 this evening, flash crashed in Mozilla Firefox which is not that uncommon, and from there Firefox closed, and so did my Microsoft Word and Excel apps that were open. From there, my computer began to shut down and restart. When it went to restart, all it could do was go to the opening Lenovo screen which gives you the F2 (setup option) and F12 (multiboot menu option) as it typically does. Besides a thin strip at the top that appeared after about 30 secs that only displays moving static that eventually will just stick, that is where the boot process ends. No Windows 7 screen, and certainly no opportunity to boot into safe mode to check for any problems. The screen freezes and goes nowhere.
 
So basically, all I'm getting in terms of boot options are lenovo features, not windows 7 features, meaning it won't boot into windows 7 or windows 7 safe mode no matter what I try. The biggest problem here is that I have no windows 7 disc to even try to boot from my dvd drive.

Hi, Bought a new Lenovo G50-80 , it has AMD radeon R5 M330 graphics card and installed Windows 7 x64 . Brightness control doesn't work. Thought it might be issue with Display driver and hence tried to install AMD VGA driver the installation fails with error as below. "Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags(), depthBufferSize 24 , redBufferSize -1 , greenBufferSize -1 , blueBufferSize -1 , alphaBufferSize 8 , stencilBufferSize8 , sample -1 , swapBehaviour 2 , swapInterval 1 , profile 1) This is most likely caused by not having the necessary graphics drivers installed. Install a driver providing OpenGL 2.0 or higher or, if this is not possible make sure the ANGLE Open GL ES 2.0 emulation libraries (libEGL.dll, libGLESvs.dll and d3dcompiler_*.dll) are available in the application executable's directory or in a location listed in PATH"Please let me know the right path for AMD drivers and how to fix the brightness issue

First step is open device manager and look at the listing of hardware.  Make sure your device is listed, without yellow or red markings.  If the device is present, does not have warning / error indicators you can right click on it to show properties and then look at the driver  that is attached.
 
Secondly - the screen capture you shared shows a message box from AMD / ATI stating that new software / driver is ready, and may be what you need to apply in this situation.

Hey guys so I just got a brand new Lenovo Y700 laptop yesterday and when I just opened it and was setting it up the display was fine it was like normal. But when I went onto the bed and adjusted the screen (i.e tilted it) it suddenly became extremely dim to the point where I couldn't see anything. The issue with this was that when I shifted the screen back and forth to find a position where the display would work fine it'd go back to normal for awhile before going back to being super dim. My adaptive brightness and auto brightness are turned off i'm not really sure what's the cause of this since its brand new, please give your opinion.

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.
