Lost brightness on screen

After I downloaded new stuff, my screen appears to have lost some of its brightness. The downloads were just updates that Apple recommended. The color is like when the computer is in relax mode before going to sleep mode. Please help.

I figured it out. In the find file there is a category for display and there is a brightness gauge.

Windows 8.1 Update Causes Lost Brightness Settings / Screen is Dim

I updated from Windows 8 to 8.1 and the next day my screen went dim and I could not adjust it neither with the keyboard +/-, nor with the onscreen graphics dashboard, nor within the power settings.
How do you fix it?

Sometimes Windows updates will break your graphics driver. That is because Intel and NVidia do not update their graphics drivers on the same schedule that Microsoft
updates Windows, and sometimes the updates are incompatible and cause the graphics driver to do wonky things. In my case that came in the form of lost brightness settings.
I searched these forums for a fix and I could not find one, so now that I know the answer, I am sharing it here.
How do you fix it? You have to reinstall the graphics driver. This is how I did it.
I found the graphics driver install file that was already on my computer and I ran it. It reinstalled the driver in about 5 seconds and my screen brightness functionality was restored.
Where is my graphics driver install file? On my computer it is here:
D:driversVGAIntelx649.17.10.2932\Setup.exe
Yours is probably in a different but similar location depending on how it was installed and what brand it is, etc. I have a Lenovo
P400 touchscreen laptop with an Intel HD 4000 Graphics.

Guide to Upgrading to Windows 8 on the T540p (+fix for brightness/black screen on wake)

Hello all. I recently received my new T540p running Windows 7. Although I probably would have qualified for receiving Windows 8 recovery media from Lenovo, I went ahead and did the upgrade myself since I had a copy of Windows 8 laying around (and because I'm impatient). I'm fairly tech-savvy and expected the process to go smoothly; boy was I wrong. I decided to write up this little guide after having a thoroughly annoying time upgrading in the hopes of saving someone else out there from the hassles I underwent.
NOTE: The most troublesome part of the whole process was figuring out why the screen brightness was no longer adjustable and the display would not turn on after waking from sleep (black screen) after upgrading to Windows 8. Skip ahead to step #9 if that's the issue you're having.
Step #1: Make a bootable recovery disc or USB drive
This is important in case anything goes wrong during the upgrade or you decide you despise Windows 8 and want to bring back Windows 7. The T540p comes with a recovery partition in the hard drive (like most laptops nowadays I assume) which allows you to completely wipe your computer and reset it to its original factory state (the same as when you first received your computer). This is normally done by restarting your computer and hitting the enter key to interrupt normal startup and selecting the recovery option from a menu. I wrongly assumed that I would still be able to conduct the recovery after installing Windows 8, but for some reason after upgrading I was unable to start a recovery from the recovery partition. Thus it's important to create a set of recovery discs or a recovery USB drive yourself BEFORE starting the upgrade. Lenovo includes a program which makes this step very easy; see this page for details: http://support.lenovo.com/us/en/documents/ht004960
Step #2: Uninstall certain programs BEFORE upgrading
I skipped this step because I forgot about it. I haven't noticed anything adverse (aside from the brightness/display problem which I assume is completely unrelated), but Lenovo does suggest to uninstall certain programs before upgrading so it's probably wise to do so. Here's the list:
    - DisplayLink Core Software
    - Intel(R) USB 3.0 eXtensible Host Controller Driver
    - Lenovo Solution Center
    - RapidBoot
    - ThinkPad(R) Bluetooth with Enhanced Data Rate Software
See this page for details: http://download.lenovo.com/lenovo/content/windows8/upgrade/think/notebook2_en.html
Step #3: Download and save wireless drivers to external media BEFORE upgrading
After upgrading, I discovered my wireless didn't work and thus I couldn't connect to the internet. I wound up downloading the wireless driver to my phone and transferring it to my T540p. You could also use an ethernet cable to connect to your wireless router or cable modem. But if you have a USB drive, CD, DVD, external hard drive, whatever, save yourself the hassle and download the wireless driver ahead of time. You will need to know the brand of the wireless device (Intel or Realtek); look it up in your email receipt or from the Windows Device Manager under "Network Adapters". Mine was Intel. After figuring out the brand of your wireless device, go to the T540p drivers page here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for a drop-down menu that says "Component" and select the option "Networking: Wireless LAN" (LAN, not WAN!). The page will refresh to show only the wireless drivers. Select the Windows 8 64-bit driver that matches your brand (I'm assuming all T540p laptops are 64-bit. If I'm wrong, please correct me). Download that sucker and put it to on the external media of your choice to use later!
Step #4: Begin Windows 8 upgrade
You'll obviously need to have a valid Windows 8 key or purchase a copy of Windows 8 for this step. I had a valid Windows 8 key that had been used on an old computer which died (hence my new Lenovo), so I reused it. This requires Windows 8 to be activated by phone which isn't nearly as scary as it sounds. We'll get to that later.
There are two ways to do upgrade: use a Windows 8 installation DVD or download a web installer. I had a Windows 8 key from a previous web installation and went with downloading a web installer. If you have an installation DVD, just insert it and get started. If you prefer to download a web installer, go to this page: http://windows.microsoft.com/en-us/windows-8/upgrade-product-key-only I think product keys are tied to either Windows 8 or Windows 8.1, so select the one that you have a key for and download the appropriate one. If you're not sure, you may have to try both.
During the upgrade, you will be asked whether you want to download updates (I assume this updates the installer) and afterward you will be asked to enter your product key. For some reason, when I downloaded the updates my product key would get rejected. I just restarted the Windows 8 installation, skipped the updates and then my product key was accepted. I don't know if this is tied to the fact that I was reusing a Windows 8 key (again, which had been used on a now dead computer) but if you find your key getting rejected then you may find skipping the updates helps. If this doesn't work and you're using the web installer, try downloading the other web installer (e.g. if you're using the Windows 8.1 web installer and find the key is rejected even after skipping updates, your key may actually be for Windows 8 and you should try downloading the Windows 8 web installer).
The installation itself should be a fairly straight-forward process. There are lots of guides online in case things go awry. If you have any trouble or errors, you should hopefully have made recovery media for worst case scenarios where you need to start from scratch.
Step #5: Install wireless driver & connect to your router
You should now have Windows 8 up and running on your system, but no wireless. Now's the time to use that driver you downloaded earlier. Install it and you should now have wireless access. Connect to your router and get online so we can start some badly needed updating!
NOTE1: your touchpad/trackpoint/keyboard experience will be especially funky at this point. That's because the drivers for them haven't been installed. Normally the touchpad won't be active while you're typing, but because the drivers haven't been installed you'll notice you'll accidentally move the mouse or click while typing (e.g. when entering passwords). Not to worry: this will go away when we install the Lenovo drivers now.
NOTE2: your function keys won't work (adjust sound, adjust brightness, etc.). That's also because of the drivers.
NOTE3: you may notice your screen's brightness may not be adjustable even from the Windows menu. Again, that's also because of the drivers. Hang in there!
Step #6: Activate Windows
Now that we're connected to the interwebs, it's time to activate Windows. If you're completely new to Windows 8, here's where you go:
-move your mouse to the upper right corner then move down
-select "Settings"
-select "Change PC settings" at the bottom
-select "Activate Windows"
This is where you'll enter your product key. As I've said before, my product key had already been used on an old, now dead, laptop. Reusing a key requires you to do a phone activation. If you find your product key gets rejected, go to the phone activation option and follow the instructions. An important note: at some point you will probably be asked how many devices/computers you installed Windows on. The correct answer is "one"; if you accidentally give another number, you'll need to call again and start over. (I'm assuming you're not doing anything illegal. As far as I know, there's nothing wrong with you reusing your key so long as you're no longer using the old computer Windows 8 was installed on, e.g. when that old computer no longer works. But if you're trying to install Windows 8 on multiple computers and you can afford to buy a new copy of Windows 8, shame on you. It takes a huge team of coders and support staff to make a product like Windows happen; help them pay their bills by purchasing a legal copy of Windows 8. Students can even get a copy for less than $70 with proof of student status. http://www.microsoftstore.com/store/msusa/en_US/pdp/Windows-8.1-Pro-for-Students/productID.288769600...
Step #7: Install Lenovo-specific updates and drivers
I typically hate all the crapware and bloatware companies include with new laptops, but Lenovo does make some which are useful. Their system updater should take care of downloading the rest of the drivers you'll need instead of having to download them all individually (with one exception: the graphics drivers may require a separate download later). Download the system updater here and keep running it until there are no more updates to download: http://support.lenovo.com/en/documents/ht080136
Step #8: Install Windows Updates
Load up Windows Update and start installing. If you're completely new to Windows 8:
-move your mouse to the upper right corner then move down
-select "Settings"
-select "Change PC settings" at the bottom
-select "Update and recovery"
-click the "Check now" button to check for updates
-click the "View details" text link to see the available updates
-click the "Install now" button to begin installing immediately
(Yes, the Windows 8 interface is dreadfully unintuitive unfortunately. Watch some Windows 8 tutorials on YouTube if you find yourself having trouble. Already looking forward to the next version of Windows!)
You'll also want to download the Windows 8.1 update if you installed only Windows 8 (the update to 8.1 is free). The download is available from the Windows Store.
Step #9: Install graphics drivers (if you're having display problems: unadjustable brightness, black screen on wake from sleep)
As I stated earlier, this was the most frustrating part of the installation process. My T540p came with only an Intel HD Graphics 4600 card, but it seems some others include a dedicated NVIDIA card. Whatever updates were installed with Lenovo's System Updater and via Windows Updates didn't seem to do the trick. I even updated the driver with the latest from the Intel website to no avail.
The solution, at least in my case, was simple: go to the T540p driver's download page and download the graphic card drivers appropriate for your system. Go here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t54... Look for the "Component" drop-down menu and select the "Display and Video Graphics" option and download the Intel and/or NVIDIA drivers appropriate for your system. (I have no idea what the Intel Wireless Display driver is for, so I avoided it thinking I don't need it)
BONUS Step: Go to ninite.com to download commonly used programs
Shameless plug for one of my favorite websites. It lets you pick from a list of commonly used programs, then downloads and installs each of them all automatically (and skips all toolbars/extra junk downloads). Makes getting started on a new computer a breeze!

Hello Yolanda,
a) I noticed that I can´t install MediaCenter on Win8, but just on Win8 Pro.
b) My problem is, as described, that installing "MediaCenter" on either "Win8 Pro" or "Win8.1 pro", though the "Media Center" key is accepted,
which I once 2 years ago downloaded on ANOTHER "Windows 8 Pro" computer, for free as it was a gift of Microsoft at that time - You could reserve = get up to 5 Media Center licenses per "Windows 8 Pro" computer for later use
on OTHER "Windows 8 Pro" computers - but never used ( i.e. NEVER USED FOR ACTIVATION ),
but after the first reboot, I am running "Windows 8 Pro with Media Center" WITHOUT LICENSE, as shown in the system screen.
Neither my "Windows Media Center Key" nor my "WIndows 8 Pro key" is then accepted to change the situation - I mean the keys I entered just before during the installation process of "Windows 8 Pro" and "Windows Media Center".
I am shure that I did not use the "Windos Media Center" key, as I have a list of personal keys I got for free from Microsoft, and I marked those 2, I used for other "Windows 8 Pro" computers.
So fact is, that with my brand-new computer, 32 Gigabytes of RAM, 4 Cores, "Win8 Pro" installed, I am forced to avoid the installation of "Windows Media Center", though I got valid licenses.
So your answer was not quiet helpful, as it does not change anything.
Sincerely
Rolf

I have a bright white screen when turning on my ipod nano 7th gen. Have tried resetting etc etc. Any further ideas?

I have a bright white screen when turning on my nano 7th gen. Have tried resetting and restoring settings - no change. Any ideas please?

Hello pipworms,
I would be concerned too if my iPod nano's was just showing a white screen. I recommend following the steps below:
Display shows a white screen
Try putting the iPod into disk mode:
Reset the device (Reset the device by pressing the Sleep and Home buttons simultaneously until the display shows the Apple logo. This should take about eight seconds).
When the Apple logo appears, press and hold the Volume Down and Volume Up buttons simultaneously until the device enters Disk Mode.
While the device is in disk mode, sync it to iTunes and try to restore.
I got this information from the following article for the 6th generation iPod nano. The steps are the same, except I updated the reset steps with the reset for the 7th generation iPod nano:

Mountain lion really bright white screen on boot?

Since I installed Mountain Lion I can't seem to get rid of the really bright white screen with Apple logo at bootup.
I RESET the PRAM and it will work for one boot and then go back to the really bright screen burning my irises out.
It can't be the battery because my computer keeps the time and date correctly.
I have also checked the STARTUP Disc and that is working right too. I even tried redoing permissions through Disk Utility and that didn't help.
Anyone have any ideas on this one?
Thanks.

Anyone have a answer to this?

Bright White Screen.

My Ipod Nano was working fine. I turned it off, and went to bed. The next morning I got up and turned it on. All that showed was a bright white screen. I reset it a couple of times, I pluged it up to the USB port, and I let it die completely. None of those things helped to fix my Ipod. It was not dropped and it did not get wet. All I did was set it down. When plugged up to the computer the computer will recognize it, but then it won't, yet after that it accepts it again. Does anybody have any words of wisdom? Does anybody think Apple will fix it?

Try this:
When your iPod comes up with the white screen, hold the center and menu buttons simultaneously until the screen goes black, then immediately hold the center and left (rewind) buttons. A menu should come up that shows you a few options. If this menu comes up, it might just mean that your internal storage is dead. If nothing comes up, then you might have a total hardware failure. If it is just the storage, the repair should cost less than buying a new nano or having an Apple Genius go in and repair multiple components. You might be able to attempt the repair yourself, but I really do not recommend that.

IPhone frozen/no brightness/white screen

So yesterday it start with my iphone telling me that I needed to connect to iTunes and restore because I couldn't make or receive calls. I reset it, and seemed OK. I later tried to play doodle jump, which crashed upon opening, so I reinstalled it to no avail. I discovered this morning that wasn't just doodle jump, but all 3rd party apps. It also went through stages of not turning on, telling me to restore it, and still having an image on the screen but there was absolutely no brightness to it, and instead of the screen going black when I press the sleep button on top, I would get a bright white screen. Giving up on resets, I came home from school and restored it, and it worked perfectly. Now it's 5.5 hours later and it just froze, unfroze, and had no brightness. I reset it, and now it wont turn on.
Any suggestions? Thanks

My iPod Won't Show Anything But A Brighter Black Screen.

My iPod Touch 5g had been working just fine for the last 8 months, and even this morning. But, as I was getting into my car, I turned it on and nothing but a brighter black screen showed up. After a few tries of just pressing the on/off button it finally turned on. It worked for a while then, it just wouldn't turn on at all. When I got home, I plugged it in to the charger and it did the same brighter black screen. It's like it turns on in the background but doesn't let the actual screen show. I've plugged it into my computer and the wall, I've held the home and on/off button together but neither are working. It will also play music from my speakers if I press play on the speakers but it won't show me anything but a brighter black screen. Any tips?

Brighter black? Black is black. It has no shades.
Please tell me that it has NEVER been jailbroke. If that's the case, here are some standard repair procedures:
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, if you have IOS-7, read this.

HT1430 My new iPAD3 has uneven brightness on screen. Left half is brighter than right half. Any suggestions how to fix it?

My new iPAD has uneven brightness on screen. Left half is much brighter than right half. Any suggetions to fix it or shall I go for warranty replacement?

If restarting or rebooting doesn't resolve the issue and the device is new, I would contact Apple or wherever you bought the iPad, show it to them and if they can't figure out, ask for a replacement.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Why are sections of my video exporting as a bright red screen?

I am using adobe elements for the first time on my macbook pro.
I have been editing a .mov file which was recorded on my canon powershot sx40.
The editing went very smoothly and everything played fine whilst editing, no rendering indications, etc as it was a very simple edit.
However, when I exported the movie, both to a quicktime movie, and to a dvd, sections of my video dissappeared and were replaced by a bright red screen.
I have no idea why this is happening or how to rectify it. Has anyone experienced this before? Any suggestions?

lucydawson84
What you are seeing in Edit Menu/Project Settings/General is perfectly normal. So is the what you are seeing for Edit menu/Project Settings/Capture and Video Render there. So, I am not sure where Hunt is coming from with the HDV comment.
I have looked at a sample of video from your brand/model camera via a QuickTime export and do not see the problem that you describe. The sample video is
1280 x 720
29.97 frames per second
AVCHD video compression with a .mp4 file extension.
I used the Premiere Elements 11 project preset of NTSC AVCHD AVCHD LITE 720p30 which appears to be what you or the program selected as well.
Consider creating a new project with the same NTSC AVCHD AVCHD LITE 720p30 project preset and importing only a video clip. Do nothing to the video clip and export it to a H.264.mov file saved to the hard drive. Determine if the red areas appear in this video.
What did you do with the Bitrate Settings? Leave without check mark or with check mark and filled in bitrate in kbps (kilobits per second)?
We will be watching for your follow up. I will look at the DVD-VIDEO side of this later.
Thanks.

Display has lost brightness

I have a two year old MacBook Pro that has been amazing. The display, however, has lost brightness to the point that the whites no longer pop and almost look greyish. This makes some text difficult to read. I have auto adjusting brightness turned off and have tried to adjust the viewing angles with no noticeable difference.
I know displays lose brightness over time, but this has become a usablity issue. Has anyone had any luck getting Apple to replace their display because of this issue? My wife's MacBook is blinding in comparison. I'm trying to decide if the 45 minute trip to the Apple Store is even worth it.
My AppleCare runs out next March by the way.

By all means, report this problem to Apple before your Applecare runs out. Whatever is wrong, it should be covered. Your display should not be dim after so short a time.
Good luck!
