Windows On Mac :: Screen Brightness Control Not Linear In Boot Camp
Jun 13, 2009
I bought this c2d macbook pro 15'' in early 2007. Today I installed windows 7 on it (bootcamp 2.1). Everything worked perfect except the screen brightness control. The strongest level is very bright (same as the one in Mac), but the second level is very dim. I remember having this problem back in 2007 when I installed winxp on my mac. Looks like the problem still exists. Anyone here knows how to fix it?

The lowest brightness setting in XP (Boot Camp) is much higher than the lowest setting in Leopard. Is there anyway to further reduce the screen's brightness in XP?

I've got a 2010 i7 15.4 MBP, after installing boot camp drivers from MAC OS DVD, I could not find any option about how long to dim screen brightness. However, my friend's 13.3 MBP does have. What about yours, guys?

I don't know if anyone posted this issue before. I can not control screen Brightness on my MBP 13'. I tried my F1 and F2 key and the Nvidia Control Panel, either of them is working. I installed all the drivers from the CD and it can actually show the icon in the center(bottom) of the screen when I hit the F1 or F2 Key. However, the brightness adjust does not work,the screen stay the same.

If I log into Windows as a normal user (not administrator) and open the Boot Camp Control Panel, I'll be missing the Startup Disk pane. The only ones available are Brightness, Keyboard and Trackpad.
Is there any way to get the startup disk tab to appear while logged in as a normal user? I don't like the idea of having to run as an administrator all the time in Windows.

so I'm planning on buying and LED Cinema Display to go with my Mac Pro. I have a few issues before I pull the trigger...
Currently, I'm using a 23 inch Acrylic Cinema Display and have found that there is no way to adjust overall monitor brightness. Even using the ATi control panel (my Mac Pro has an Apple branded ATi 4870), there are no true brightness controls either on the software side in Windows (I haven't found a way to change brightness in Windows like I do in System Preferences in OSX) or on the hardware side (no buttons on the monitor itself).
Basically, as soon as I use bootcamp to reset into Windows, I notice that the screen immediately goes to the lowest brightness (even though I was running the max in OSX before switching) settings as soon as I go into the desktop. Playing games like this is irritating.
I know the LED Cinema Display also has no brightness buttons on it, so will I still be SOL?

I am using a Samsung monitor so therefore cannot control th screen brightness with the F1 F2 keys.
I tried Shades but it messes with the colour making it look a little washed out and not good.
Are there any others I could try ?

I've encountered an interesting, if not incredibly frustrating, problem on my Macbook Pro and I was hoping someone might be able to help me diagnose and rectify it. I had installed XP via Boot Camp 1.1 in August successfully and used my XP partition for a few months. Then, one day, when I went to boot into XP, after selecting my XP partition at the startup screen, my computer went to a black screen with no cursor or error message. I had no idea what to do, so I decided to simply delete my partition and create a new one and reinstall Windows. After deleting it and firing up Boot Camp, I encountered the very same black screen when Boot Camp restarted my computer. It would go to the grey startup screen first, but then to a black screen. The XP install disc would seemingly spin up properly, but nothing ever showed on screen. I then tried any number of possible fixes, including zeroing my entire hard disc and reinstalling OS X and Boot Camp (now 1.3), but have had the same result each time. I have begun to suspect that the problem is related to the EFI, but I don't know very much about that sort of things and don't really know how to adjust its settings or reinstall it. I've downloaded the most recent EFI firmware, but when I try to open the file OS X insists that my firmware is already up to date. I've been scouring the internet for the last couple weeks and am yet to come up with a solution.

I have just finished installing Vista Ultimate (64 bit) on my new Mac Pro, and the screen is really dark, and I can't seem to get it any brighter.
My graphics card is the Nvidia 8800gt, I am using an old 23" ACD through the ADC/DVI adaptor.
The screen was nice and bright all throughout the installation, but after I installed the boot camp drivers from the Apple install disc, the screen became really dim. If I open the Nvidia control panel and try and change the brightness from there, the screen stays dim, but just gets really washed out.
The weird thing is, it translates back onto the OS X side. When I restart after being in Vista, the display is still very dim - I have to go in the Displays system preferences and manually change the brightness back up from minimum. Conversely, when I boot into Vista having been in OS X, the screen is initially bright through all the login screens, but then switches back to being dark as soon as I have logged in.
There is probably a really simple solution to this, but as I am completely unfamiliar with Vista, I'm stuffed if I can work it out. Any advice is gratefully received.

I have an older MacBook and when I bought it, from a friend, it already had windows running on it. Just the other day I went to restart my computer and all I got want the black screen saying that the computer was turned off wrong and to choose the start up mode. I tried the last known option and nothing happened besides restarting to the same screen. Then I tried the normal mode and that didn't work and safe mode did the same thing, starting back up to the black screen. Is there something that I can do/fix, or does this require some professional.

I have a 1st generation macbook pro running snow leopard 10.6. I've been trying to install windows xp, vista, or 7 using bootcamp but for some odd reason i cannot boot into the cd. I put the cd in and made sure the macbook is reading it (which it is because the icon shows up on the desktop) before i hit "start installation". the laptop would restart but it doesnt boot into the cd, it just goes right into the gray screen and stays there while i hear the cd spinning. I've installed windows xp using this method but that was about 4 years ago, for some reason the hard drive died on me so i have to do this whole process over again. I dont recall having this problem either.

I know this happened before in the old Macbook Pros by the look of things when I searched around.Basically there is a noticeable high pitched whine when the screen brightness is either not completely off or max.

In retrospect, I should have ignored it when Apple Software Update told me about the Boot Camp 3.2 upgrade for my 2006 Mac Pro running x64 Win 7 ultimate. When I ran it, it overwrote my blue tooth driver and my keyboard stopped working. Thanks for the folks at Mac Rumors forums, I was able to go through the procedure to get it working again, and I also had to update the video driver (again) from ATI for my 3800.
So then I decide to reboot into MacOS and discover that my icon for selecting the boot disk was gone, not to mention any directory or programs in the start menu. This happen to anyone else? Do I have to downgrade to 3.1 or does anyone have a recommendation to get 3.2 working?

Won't boot up past this screen, this is the first time this has happened. I am fairly certain it is related to an attempt to install SP3 (I had removed it in favor if SP2 to hopefully fix some wireless issues). I noticed when I shut it down last time that it was installing updates, which most certainly included SP3, and then I left the computer. Maybe the install failed? If so, how can I fix this? Any way around other than reverting to a backup? (I think the clone I have of it has SP3 on it)

I cannot control my screen brightness using the F5 and F8 keys. The only way I can adjust it is through System Preferences. I tried just F5 fn F5, Control F5, Option F5 and Command F5 and non work.

In my attempt to install Windows XP via Boot Camp, I accidentally inserted an SP1 disc instead of the SP2 disc that I have. The installation proceeded to the point where it does for most who attempt this: the screen where you are prompted to press ENTER. I could not proceed and therefore restarted the iMac and held down the mouse button upon start-up to remove the CD.
HERE IS THE PROBLEM:I can not boot into OS X because the keyboard shortcuts (those that might allow me to select which partition to boot from and/or reset PRAM) seem to be disabled. Instead, a reboot always ends at a black screen with a blinking DOS-esque cursor, or the prompt: "No bootable device -- insert boot disk and press any key."
I have attempted inserting my SP2 disc at this point, to no avail. My keyboard seems to be disabled, as if the SP1 install proceeded just enough to establish itself as the boot drive without drivers for the keyboard. I've tried using all 3 USB ports, disconnecting other USB devices. Oddly, my bluetooth mouse works to eject the CD on reboot...

Am I the only one having this bug? I have a 2009 24" iMac Radeon 4850 and after installing the 10.5.8 combo every time the machine boots the brightness is set to maximum.
I tried zapping the PRAM and that didn't help.
The other problem I noticed is that my startup network shares, even though checked to "hide" pop up finder windows at boot time. It never did this before (even without hide being checked).

I have an '08 Octo 2.8.
I created a Boot Camp Partition (an entire drive, actually) and installed XP. The install went off without a hitch ... Except, having rebooted to Mac OS X (10.6.1) there is no way to boot Windows again. Going to Preferences->Boot Disk shows no Book Camp bootable drive.

This is the 1st time i got a Mac , i bought a black Macbook 2.4GHz some days ago .
I installed Windows Vista Ultimate using Boot Camp , and all went smoothly .
Only 1 prob is when restarting , i have to wait too long for the Windows to log on , i think about 1min with the black screen.
And if i want to boot in Mac OS , i have to push down the D button or the Alt, it takes quite a long time too .
So do you guys have any solution to this problem ? I want to get rid of the waiting time, way too much.
And do you know how to make my Macbook jump right in the choosing section when it starts ? ( so that i dont have to push down any button when it starts )

Is there a way to make the Boot Camp menu the default boot screen, as opposed to holding Alt? This is the latest SL release, if that matters.
I know this is possible in some manner, our networked iMacs all do it; they start up and give the option to boot OS X or Windows, with a countdown to boot the default OS. I'd just like the same thing to happen on my MBP.

I have been trying to install Windows 7 (yes, legit copy) to my Macbook Pro the whole day, but I keep on getting this error message saying "Press any key to boot from cd or dvd . . . ."
When I press any key on the keyboard, nothing happens. I know this copy works because I've tried this on VMWare 3. (I'm going to Boot Camp of BIOSHOCK!)
What I've Tried:
Deleted partition, recreate partition and choose the Windows 7 disk as startup disk.

Well I installed Vista Ultimate using boot camp on my 27 inch iMac using 10.6.2 and now I can't get it to boot in OSX. I tried holding the command key when rebooting but it just goes into the windows part. Looks like windows took over. Does anybody know how I can get it to boot in Leopard?

Have the new 15" MBP with i7 Processor. I had another MBP with a 7200RPM drive and installed drive in the new i7 Mac. Computer was working fine until I installed Windows via Boot Camp. I can't boot to the Mac Partition any more, the partition is there but when you try to boot to it you just see the Apple logo and NO circle. I cannot boot to the install CDs or a bootable external drive. I target disk mode the computer and used another computer to boot using the drive in the i7 unit and it's fine and I can see all the information. I tried booting the i7 into single user mode and saw the following message:
efiboot loaded from device: Acpi(PNP0A03,0)/Pci(1|1)/Ata(Primary,Master)/HD(Part 2,Sig********-****-****-****-************)
boot file path: SystemLibraryCoreServicesoot.efi

I have dual ACD's. How do I make it so that both screens have the same brightness? If I adjust the brightness in the display settings it adjusts the main screen, but then not the other one. How do I make them the same?

I just installed Windows XP to a Boot Camp Partition on my MBP. However, rebooting is a hassle and naturally I want to avoid doing such as often as possible. I think running Parallels Desktop would suit my needs quite well. But here's the catch: I want to be able to use one partition to serve both of those needs. In other words I want have the option of booting through both Boot Camp or Parallels.
How would I go about doing this? I already have a XP installed via Boot Camp. So if there is a method where I don't have to reinstall, great, but I am fine with deleting stuff.

I just purchased a new iMac (2.66 c2d & 4gb of ram), Parallels 4, and Windows XP. I would like to get great performance whenever I use Windows XP and would like to know which installation procedure would help accomplish that.
Would Parallels provide me with a better user experience by installing Windows directly via Parallels OR by having Parallels utilizing a Boot Camp Partition? Which is better and why? Also, how much memory should I allocate to Parallels/Windows XP?

Last night I installed VMWare Fusion and Windows 7 on my Unibody MBP running SL. When I use Fusion, my computer slows to a crawl. I spent a few hours getting Windows set up and installing software last night.
I would like to try using Boot Camp instead, but do not want to lose all of the software and files that I have installed. Is it possible to set up Boot Camp, and keep the same Windows setup?
