Windows 8 Bootcamp Brightness Issue

I have a MacBook Pro with Retina Desplay 15" with bootcamp installed with Windows 8. I use an LCD Cinema display at my desk for more screen space and it works fine when I'm using OSX but not with Windows 8. No matter how I change the settings I can't get the brightness on the display to change. It is always at the highest settting and it is super uncomfortable to use. It may be a problem with Windows 8 and extra displays but that would be really weird for an OS like Windows.
Does anyone know how to fix this? It would be a great help.

Are you trying to change brightness via that boot camp diamond icon in the system tray? Have you also disabled adaptive brightness in power settings?

  • Win on Bootcamp brightness issue

    Hi,
    I am running bootcamp on MB (late 2008), with Win Vista (32-bit). The screen brightness on the lower end is stuck to an insanely high level (around 50% of the MacOS level) and is proving to be a considerable strain on the eyes. What might the issue be, and how can it be resolved?
    Thanks!

  • W530 windows 10 + nvidia brightness issues on battery

    System: w530 with discrete nvidia set in biosOS: Windows 10 clean installProblem: Whenever the power cord is unplugged, the display dims and/or color characteristics change, which is most visible on white backgrounds such as switching between browser tabs. There were similar problems in windows 7 too, but the lenovo power manager had some settings which used to work for me. There is no (lenovo) power manager for windows 10. I have disabled all adaptive/auto/battery saving features in power management, and yet this happens. My settings for battery are same as they are for A/C. I'm using the maximum performance profile. Most results point to Intel's power saving settings. However, I am using an nvidia card only, and they don't apply. 

    Yes, the only driver active is nvidia's. Like I said, there were similar problems on windows 7 too, but from what i remember, one of the profiles/settings in lenovo's power manager used to work for me. On win 10, I have exhausted all the options for disabling any sort of battery saving features and it still happens. I'm also using whatever software is available for win10 from lenovo's website, but that didn't really make any difference. The easiest way to reproduce it is to be on the desktop screen and unplug the cord. You would see the screen dim.  Edit: Found some mention of the exact same problem on reddit. https://www.reddit.com/r/Windows10/comments/35f9k8/screen_brightness_keeps_changing/ Edit2: Another detailed account of the problem: http://rog.asus.com/forum/showthread.php?43315-Auto-contrast-is-driving-me-nuts!! It looks like an nvidia driver bug. Can lenovo acknowledge/patch the issue ? Ironically, for once, linux is working better for me than windows on this system. 

  • Windows 8 via Bootcamp Brightness Problem, Buttons working.

    I've installed windows 8 via bootcamp on my 2011 mbp and installed the drivers from apple. But the brightness(backlight off my screen can't go to full, except the first seconds when booting into windows. When is push the function keys the brightness doesn't go higher. Because the windows brightness menu says that the screen is at full brightness. When I lower the brightness (In the menu or with the buttons) the screen goes completly black when the bar says that the brightness is at a quater. Does anyone have any solutions? If you guys need screenshot I can provide. Thnx in advance!

    I have been having the issue of no brighness control when running windows through bootcamp for about 6 months now and have not found any applicable solution online.
    While messing around trying to figure it out yet again I noticed that my monitor driver was signed by team viewer...
    Sure enough clicking the roll driver back button resolved the issue by rolling the driver back to the Microsoft driver...
    So long story short:
    Right click "My Computer" click properties
    Click device manager (lop left of window)
    Expand Monitors section
    Double Click monitor
    Click driver tab
    If the driver here is not signed by Microsot or Apple click the roll back button. My driver version is 6.1.7600.16385 (Driver date 6/21/2006)
    Rolling this back instantly resolved my issue. I will now propagate this post to all the threads I saw regarding this issue.
    I am running windows 7 x64 Ulti on a 15" rMBP.
    Best of luck

  • After upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues

    after upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues. my computer now freezes and programs close randomly. The usual command for opening windows with bootcamp doesnt work. once in restarted my computer after it froze and it rebooted in windows automatically. i really just want to know if there is a way to take the upgrade off my laptop because it is very annoying.

    Hi Memalyn
    Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
    My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
    If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
    Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
    Let us know what you find out, and if you manage to get your space back.

  • Bootcamp With Windows 8.1 Virtualization Issues On Start

    Hi All
    Ive just purchased a new 13 inch MBP Retina with 8GB Ram
    I am a Microsoft Developer, specialising in mobile, so I installed Windows 8.1 on bootcamp, and am using windows this way 2/3rd of the time (I also use my MBP for OSX a third of the time)
    When I go into Mac system preferences and restart as bootcamp, my Mac restarts in Windows with virtualization enabled, which is essential as I am running Visual Studio's dev tools including Windows Phone Emulators.
    If I've booted into Windows via bootcamp (virtualization is enabled) and then do a restart in Windows, the virtualization is still enabled - great!
    However, if I hibernate my Mac while in Windows, or shutdown windows (which is a form of OS hibernation with Windows 8), and then restart,  the virtualization is disabled, and my emulators will no longer spin up.
    I have tried restarting windows via the bootcamp control panel in Windows, but that doesnt fix it.
    The only way to get windows running with virtualization on is to boot into windows via the bootcamp option in Mac preferences - EVERY TIME, so I am stuck with doing the following every time I want to use my mac for windows development:
    1) startup in windows
    2) Using Bootcamp control panel restart OSX
    3) In mac system preferences retart Bootcamp
    4) start Visual Studio and emulators
    Surely there must be a way of getting this to work seemlessly
    Dean

    Folks,
    If you scratch beneath the shallow Apple support surface, you'll find out that this issue has been around since 2008 (http://forums.macrumors.com/showthread.php?t=821551).
    There's nothing wrong with Windows, and your hardware (Intel CPU that is) support virtualization. What Apple support doesn't tell you is that engineering has a bug with firmware that causes this. There's also a well known workaround, painful but workaround (http://apple.stackexchange.com/a/122071/106730).
    What infuriates me is the fact that
    1. Apple support deceives and send people away by claiming there's nothing wrong (read "lies")
    2. Engineering knows about it and does very little to address it properly moving forward (read "ignores")
    3. Consumers that just accept this as-is because it's Apple (read "stupidity")
    I'm vocal about it because it is unbelievable. It's 2014 outside, and Apple neither has a basic support tracking mechanism nor is transparent about what it's doing when providing support.

  • What driver to install to fix Brightness issues on my Edge 15 with Windows 8.1

    Hi,
    On my Edge 15 with Windows 8.1, Brightness is unavailable from Windows. I can adjust brightness with the Fn keys, but it keeps resetting it's default value. Very annoying.
    There are a lot of drivers, which one should I install to fix this problem?
    Thanks,
    Heras

    Hi Heras2,
    Welcome to Lenovo Community!
    As per the query we understood that you are facing the issue with Brightness on your ThinkPad Edge 15.
    To resolve the issue please update Display drivers, Hotkey features & power management application.
    Note: before updating the above application you have to uninstall it first from Control panel –Program & feature option and after that you have to update.
    Hope this helps.

  • Windows 7 Bootcamp CPU Usage issue

    I just newly installed Windows 7 bootcamp on my MacBook Pro (2010). The installtion ran smoothly. But there seems to be a problem for me. The bootup time from being on to off or vice versa is 7 seconds flat.
    And when I play games, my CPU usage would shoot up into the 80%-100%s making my screen freeze every 2 minutes, and typing anything onto a screen would take 2 seconds for my computer to compute.
    Note: This was not the first time i install windows 7. The first time I did it, everything ran so smooth and fast. the bootup time would be at 2 seconds flat. no freezes when I play games or open anything up. How could I fix this?

    Hi,
    I have an update so I thought I would share in case any other users are experiencing a similar problem.
    I made an appointment with the Genius Bar at the Apple Store.
    I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
    Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
    I couldn't be happier.

  • Apple Cinema Display 23" brightness issue while using with Microsoft Vista

    Hello there,
    I have the following issue and was wondering if someone has an idea what the reason is or what can I do to fix this:
    I have a 23" Apple Cinema Display running with a MacPro 2,8 GHz. When I switch to PC using BootCamp 2.1 with Windows Vista Service Pack 1 32bit the screen becomes extremely dark.
    At first, on the PC side, the display has the correct brightness but after two seconds it switches to a very low brightness setting.
    When I go back to the Mac side the brightness setting on my Cinema Display has changed to the lowest point.
    I also have a MacBookPro, with Microsoft XP installed also using BootCamp (I cannot find the version of this Boot Camp, but it is an earlier version) to change to PC. In XP, there is a driver installed that allows me to use a slider on the PC to control the monitor brightness. But with Vista this slider is nonexistent.
    I already tried changing the graphic's card NVIDIA 8800 driver to see if I can manipulate the brightness on the monitor. I realized there is brigthness slider on the Nvidia driver, but when you make brighter, the colors just get messed up, and the brightness stays as dark as before.
    We have lately upgraded to Snow Leopard and had installed Spyder on the Mac side to create a monitor profile for the Cinema Display. I already deleted the profile to see if there is a change. Nothing. I already went back in time on my PC (Restore Point), also nothing.
    Could I download a driver for Vista, so that I have a brightness slider on the PC side, so that I can adequately change the brightness to its correct setting.
    It is amazing how the lack of correct brightness in a monitor, can ruin your entire working day! Very frustrating!
    It would be greatly appreciated if someone has a solution for this issue! Thanks a lot!
    Emil

    Okay, I came across a thread that implies there is a problem with using the Apple ADC-to-DVI adapter to attach the older "acrylic" 23" Cinema Display to a Mac Pro DVI graphics card. Basically, the workaround is to NOT use the USB part of the adapter (disconnect it).
    1) In OS X, set the desired display brightness.
    2) Disconnect the USB cable coming from the converter to the Mac.
    3) Restart into Windows.
    The brightness setting should now remain as it was under OS X.
    Confirmed to work on my Mac Pro v1,1 (dual 2.66 Core 2 Duo) with nVidia GeForce 7300 GT video card running Windows 7 x64.
    Link here: <http://forums.macrumors.com/showthread.php?t=790910> for credit to resolution.
    Of course, you lose the functionality of the 2-port built-in USB hub in the Cinema Display, but an external USB hub can make up for that.

  • Can not reboot into OSX from Windows using Bootcamp assistant

    I'm having a bit of a problem with rebooting into OSX from Windows on bootcamp. Clicking on the icon in the system tray produces a message that Windows can not find the OSX disk. Trying to open the Bootcamp preferences also generates an error. I have no problem getting back into OSX if I shut down Windows and restart the MacPro while holding down the option key. This is with a Windows 7 install on Bootcamp, but I had the same issue with a previous install of Win XP. I nuked and paved OSX and the WIndows disk between installs so my current problem is not carry over from the XP install.

    My bad I should have been more clear. The problem is actually with a XP install via bootcamp, my Win 7 install is in VM Ware Fusion.
    The XP install is on a second drive. Since you asked about this I'm assuming it may be the reason Im having problems.
    The error is I get when trying to access bootcamp via the Windows control panel or by right clicking the sys tray icon is - "An error occured while trying to access the start up disk settings. You may not have privileges ...blah, blah, blah. I only created one account and I have enough privliges to change admin stuff in windows so I cant see privliges being the issue. I reassigned the OSX partition a new drive letter and rebooted windows but this didn't help.
    The only drivers I installed, other then updating the video driver, are the bootcamp drivers

  • Windows 7 64bit speed issues

    Hi,
    Our company have been purchasing iMacs for the past 4-5 years and installing Windows XP without any problems.  Last year we started installing Windows 7 64 bit onto, the then current, leopard model without any issues.
    We have recently purchased a whole batch of i5 iMacs with lion installed. I have installed Windows 7 64 bit without any problems but have started noticing huge slowdown with what seems to be hard drive access o every single machine.  Even a single one we purchased when they first came out.
    Using Perfmon I cant see any stress on the CPU, GFX card or RAM but there seems to be something odd with the hard drive access.  I have stripped Windows 7 down to its bare minimum services removing Aero, themes, and all non essential services but still the speed issues occur.
    I have messed around with the pagefile size, indexing, etc, but nothing is having any impact.
    For example, when I save a simple spreadsheet the saving window appears in Windows 7 with the spinning circle for around 30 seconds.  This is a tiny file, why is it taking so long.  Its virtually instant if done on a Windows XP bootcamp machine or even in Windows 7 on an older Leopard iMac.
    There really isnt a great deal regarding this problem oin the internet but it has occurred on all the new i5 Lion iMacs we have.
    Does anyone have any other suggestions (serious ones ) that I could try?
    I am currently installing the 32 bit version to see if it is a driver issue.
    Cheers

    isn't apple now using propritary drive firmware in 2011 imac?
    I suspect 30 sec is drive delay spinup and is frequently happens with green drives, I have some and do this. swap for WD black or something.

  • Installing Windows on Bootcamp on new iMacs (late 2012)

    I absolutely love the new iMacs. They seem a good bit faster than my current 2009 model and make a nice upgrade for our home I am wondering about a few things, and hopefully someone here can help me get some answers on it.
    With the old iMacs I have never been able to install Windows on Bootcamp via a USB stick/HD. Since the Superdrive is removed with the new iMacs, I'm hoping that that function is finally activated… currently that function is only activated (in the EFI from what I learned) on the MacBook Pro's and Air's. I have tried to install Windows 7 from various USB sticks and HD's on several different iMacs. Some USB sticks and HD's do properly install Windows when I try the same thing via a MacBook, so the sticks and HD's are not the issue
    Does anyone have some insight in this? I don't really feel like buying the Apple USB Superdrive, which officially is not even supported on iMacs, júst to install Windows for my occassional PC game. So basically, does anyone know wether or not it's possible to install Windows on Bootcamp via a USB stick or HD on the newly released iMacs?

    I would think so
    but rather then trying to have it verified in the imac forum I would ask in the bootcamp forum if I were you

  • Trying to install Windows with Bootcamp

    Hello. First, I do know this has been a recurrent trouble for a lot of Mac user who have tried to install Windows using Bootcamp. Believe me, I've looked it up both here in the Apple Communities and in saint Google. My situation is, however, that I have replaced my optical drive with a SSD, and now my optical drive works externally, via USB. Everytime I try to install Windows in a dedicated partition in the SSD, it just stays forever in a blank screen with blinking cursor.
    Apple's troubleshot won't work for me, and I'm beginning to think that the issue has more to do with the optical drive itself. I tried:
    To install Windows on the HDD instead of SSD.
    To unplug every USB (even mouse), except for the optical drive with Windows 7.
    To install it via USB stick (creating a bootable .iso with Disk Utility). In this case the usb stick does not even appear when holding option key.
    To try another Windows 7 version (32/64 bits).
    I have even read it might be because of a bad installation of the RAM memory... this makes no sense?!
    If anyone has encountered this same situation, I'd appreciate some help. Hope I can get this done, because Steam's Age Of Empires won't ever work in OS X :S
    Thank you all for reading and helping!

    If your Mac was originally configured with a built-in Optical drive, and it was later replaced, Bootcamp knows your original configuration and will not work properly in the modified configuration, because it uses your Mac's model string (found in About This Mac -> More Info -> System Report -> Hardware) for example, MacbookPro 11,3. The only supported method to install Windows is to restore the original HW configuration and install it and then move hardware around.

  • How do I install windows using BootCamp without cd drive fot the new MBP?

    I need some softwares for my work (modelsim, altera, ltspices etc) but some of them only supports windows.
    New MBP doesnt seem to have a cd driver.
    How do I install windows using bootcamp without cd drivers?

    You can use a USB thumbdrive to do this, assuming you have access to a windows machine to format the usb stick.
    I installed Win7 on my MB Air (2011), which of course lacks a DVD drive altogether, using this technique.
    Basically, you download a tool called rEFIt to your macbook. ( http://sourceforge.net/projects/refit/files/rEFIt/0.14/rEFIt-0.14.dmg/download ) When this is installed, it gives you a boot selector menu when you boot the Macbook ('Do you want to boot to MacOS or to the USB drive?')
    Then you download and run an Apple tool called Boot Camp Assistant, which allows you to partition your HD for the two operating systems to share; it also pulls down all the windows drivers you need.
    Then prep the USB thumbdrive on a windows machine to be a Win7 installer disk. You'll want a drive in the 4gb+ range I think. You have to set up the thumbdrive to be bootable (lots of tools for that available), and then copy all the windows installation files over to it.
    Put the thumbdrive in the macbook and boot holding down the option key.
    Choose the rEFIt icon on boot, then choose to boot from the thumbdrive, then format your new windows partition to something Win7 can handle, and install windows.
    On my machine I followed a slightly more involved process and wiped out MacOS entirely. I would have kept it on a small partition if I'd had a bigger hard drive.
    If you need super detailed instructions, CNET has some here:
