Ibook display going dull, then light, then dull, then light-battery ok tho-death rattle?help?
Wondering what is going on with my ibook. The display is going light, darker, light, darker, over and over. Computer has also been totally
shutting down on its own from time to time, but starts up ok without any prob. Help? Luckily I just backed it up.
Have you tried resetting the PMU?
The PMU (Power Management Unit) has control over the backlight function, so resetting it may help.

Display goes fuzzy then shuts down
HI,
my macbook pro display just goes fuzzy all of a sudden and I can't do anything. It's hard to explain but it's just like a bunch of lines flickering. Then most of the time it shuts itself down or I have to do it manually. I'll restart it and most of the time it will just do the same thing again. any ideas about what's causing it/how to fix it? Thanks.Not still under Apple Care?
Retina or non? Have you run it w/ an external display?
Certain models from this year apparently also have a GPU problem but report back on these other questions. -
IBook G4 grey screen,then "finder" folder with "?" flashing, please help!!
Hello again my fellow smarter than me mac lovers. OK, here is my problem. I used my ibook all night last night at work. Used it this morning just fine. My teenage daughter was using it and she stated that it froze on a screen she was looking at on possible you-tube. She proceeded to turn it off (not restart), and when she turned it back on it only responded with a grey screen. After a few minutes of the grey screen, a small blue folder will flash in the middle with the "finder" face/icon on it and a question mark flashing. It stays there a few minutes, but no cursor to click on the folder ect. After several minutes of that, the screen will go black and the computer will turn off. I have tried to reset the PRAM and PMU, but no go. Do not have discs, as this was a buy this past summer refurbished. I love my ibook and really hope it can be fixed. If there are any suggestions, please let me know. If not, I guess we will take a trip to the apple doctor. Thanks again for any help you might have.
ValHello Gengap,
This sounds like a failing harddrive issue....a computer starting up with a flashing question mark means that it is unable to find the software to load up the OS. Since you don't have the discs that should have come with the computer, you can try inserting a Tiger disc, or some other equivalent OS.
Start up from a disc, when the installer opens, open up Disk Utility. In Disk Utility, you should see a harddrive appear on the top left - but if it is failing (this just happened to me on an iBook G4), then it might not be there at all.
So if you close out Disk Utility, and you try to proceed with the installation, if the disc is not being recognized, then it will not be available to select a destination disc to try a re-install.
You might be SOL in recovering any data that is on the drive. A replacement HD should be in order if you are unable to re-install the OS.
Once the replacement HD is in, when you go to set it up again, you'll want to install a fresh clean copy of the OS by erasing the HD (incase it's formatted to work for Winblows) - you'll want to re-format it to work for Mac OS (Extended), and then re-install.
I'm not sure how comfortable you are with taking computers apart or not but since you bought it second hand anyways, you won't be voiding any warranty's of any kind. I just did this very same procedure on a 12" iBook G4 800MHz.
Ifixit.com is a great place to find exactly what you are looking for with step-by-step troubleshooting guides to get your mac up and running again.
Please post back to let me know how it works.

Sattelite 1800-752S - the display goes off
Hi everybody.
I have a satellite 1800-752S.
SInce a ew months ithas a wierd problem: the display goes off. If i press and quickly release the lid button it comes back on, but after that goes off again. SOmetimes ot goes off immediately, sometimes after a few minutes, or even hours. SOmetimes it keeps being on when I am running from battery, and annoys me on AC, sometimes the versus. It works quite well, after I turn it to standby or hibernate a few times, and after a restart it annoys me.I have updated its BIOS to the lates from this site, that wouldn't help. I assume it is a hardware problem, because it is the same problem under Linux, and I have tried to install different verisons of drivers and Windows (not only the one from the Recovery CD). Did anyone have the same problem before. Any help will be appreciated.
Thanks a lot
RomanHi,
I think you are right, it's a hardware problem. But to be sure, try to connect an external monitor. If it works without problems while the notebooks display goes off, then it must be a hardware fault.
I assume it's a problem with the FL-inverter. You have to give your mashine to a Toshiba service partner for repair.

IBOOK G4 Powers on then goes to sleep after loading, any help?
I have a 12 inch IBook g4 purchased less than a year ago. On power up, screen loads, Pop-up says date set prior to March 1, 2001, icons and wallpaper load and then book goes to sleep. All in a matter of 3-5 seconds. Help me please
I too am having problems with my ibook falling to sleep or quitting. It also sometimes loses the backlight of the display. I took it to an apple authorized dealer and they eliminated the possibility of the cause being the cord, the batter, the airport card, or the ram. I also get the message of it having the wrong time set in the clock before March 2000. The time is not set wrong.
I am also having an issue with the powercord. When pluged in so I can recharge it doesn't always sho that it recharges. I have to rearrange the cord to get it to register that it is charging. This ibook is only 18 months old and giving me unbeleivable problems. My imac is 8 years old and still running...slow but running. what gives? I make my livng on this little ibook so I really need answers and the dealer is not very helpful. Please help I'm desparate! -

Colors displaying as dull yellowy-green; new monitor and calibration
Just got a new ASUS LCD monitor, and calibrated it with the Spyder 3 Express.
Now when I import a .CR2 file using Lightroom 3 to edit the RAW image, the color is displayed as yellowy-gray and dull. It looks the same when I pull it into Elements 7, unless I remove all color management (which, if I save the image, actually then renders the image colors neon and oversaturated with lots of pink and red tones). If I export the image from Lightroom 3 the image colors are correct and very different from how they look in Lightroom.
I also use the ACR editor with Elements 7 and I am having the same problem there. Upon opening an edited Jpeg or a .CR2 RAW file there, the color is displayed as dull, grayish yellowy-green.
If I view the very same image in GIMP, Picasa or on the web, as long as the colorspace is intact (sRGB), the color is accurate. Not so in Elements or Lightroom.
If you have experience with this problem is it the monitor, the calibration, or Elements and Lightroom? I am beyond frustrated and need to see my colors properly. I have not had this problem before.
Thanks for your time.I suggest re-reading C S S Simon's and my reply, including the links I provided with solutions and historical explanation – It is apparent you didn't!
Pay your money and make your display choice, but don't blame the wide gamut capable display because you are unwilling to learn how to use the technology advantages it provides!
Please read this factoid:
All Wide Gamut Displays when properly setup to display in a "wide gamut" mode such as Adobe RGB will only display images correctly in color managed applications – PERIOD.
Your Asus display has two factory calibrated modes, Adobe RGB and sRGB, which will only work properly using the color profile provide to you on CD (or downloaded) by Asus – This the monitor profile Asus used when hardware calibrating your specific serial number monitor at the factory. The displays internal LUT contains that calibration information, and there is no way for you to recalibrate it using a Spyder 3 or other hardware calibrator. I am going to paste here three separate solution alternatives I made at the other post – Use only one (1):
Solution 1) Delete your i1 Display custom profile and install the Asus provided PA246Q driver and profile. Then use the monitor's "factory calibrated" Adobe RGB wide Gamut selector mode with Lightroom and other color-managed applications. When using non-color managed applications, switch your monitor’s mode selector to sRGB. Calibration using i1 Display or other hardware device cannot be used with this option. User hardware calibration should only be performed using the monitor's 'User Mode.'
Solution 2) In addition to your Asus PA246Q wide gamut monitor, install a second standard gamut sRGB monitor. Calibrate both monitors separately using your i1 Display unit, which will create separate profiles for each monitor. Use your Asus PA246Q wide gamut monitor only with Lightroom and other color managed applications. Use your second sRGB monitor for with both non-color or color managed applications. You may still have issues properly calibrating your Asus PA246Q monitor with its proper 'User Mode' selection as others have reported, but the results should be better than what you have now.

Solution 3) If none of the above works for you, get rid of the Asus PA246Q and buy a good standard "non-wide gamut sRGB display. -
my screen is completely white, i've tried holding lock and home buttons as seen on you tube something called 'white screen of death' its goes black (think it switches off) then back to the white screen need help fast please!
If you have not done a factory reset on the device, I recommend doing a complete factory reset.
Factory Reset - Warning this will reset device back to original factory settings.
This method will not erase any MDN/MIN information
Turn off the phone
Press Power + Volume Up/Down at the same time and hold until display will show a triage android screen
Display will show:
Reboot system Now
Apply sdcard:update.zip
Wipe Data/Factory Reset
Wipe Cache Partition
Use VOL Down key to scroll down to "Wipe Data/Factory Reset", press home icon to select option and wipe device.
Display shows "All user data will be wiped out", press VOLUME Up to continue or VOLUME Down to exit.
Press Volume Up
Press Home to select "Reset System Now" - device will reboot
If the problem persist I recommend having a store technician take a look at the device.

In my case I can resume operation by taping the F1 or F2 keys. All be it an annoying finx it is at least a simple one

Srceen goes gray after the apple goes off then the monitor says no signal..
srceen goes gray after the apple goes off then the monitor says no signal.. It been working great for 9 months use it everyday for fcp.. would the video card be bad???
If the video card were bad, you wouldn't get anything to display. The fact that you get the gray screen with the spinning gear means the video card is working.
So, two things I would try, and you can pick the order. The first is to reset the PRAM. You may want to save this for last since it will reset a few of your settings. Nothing major, but can be annoying. The second is to start the system in safe mode by holding down shift while booting.
If safe mode works, then you have some corrupted preference files or some other program is causing problems. If safe mode doesn't work, you can at least see if zapping the PRAM lets you get any further along with the boot process. Only if both of these fail would I start to consider an issue with the video card. -
Help my iPod won't let me download apps... I'll put my password in then it takes me to the app but then is just goes away then I do it again an it won't load or it will just go away again plz help I want to get apps
You said you updated yur 1G iPod to 4.2.1. A 1G can only go to 3.1.3 and thus you must have jailbroken it to get to 4.2.1 and that can cause problems.

When I try to play a song on my iPod Touch, it shows the information screen for the song and then skips to a new song but then goes back to the main playlist page without ever playing a song! Help!
thats tough man, yeah exchanging it is the best option. But why do people always leave a message saying" i'll probably just by an ipod" and it's usually followed by, "even though i don't like apple or ipod" . I mean fine, if u feel like giving up on the zen micro thats fine, i personally don't care if you're going to buy an ipod. for god sakes ipod isn't even the next alternati've mp3 players, theres plenty. Are u just trying to get the creative people saying "oh man we lost another one to ipod" cuz i'm sure they don't lose sleep over u wanting to buy an ipod instead of a zen. *done ranting*

Just updated to Yosemite on my MBP. After shutdown now when I login, it starts the process (the bar starts to move), then the screen goes black, then it asks me to login again and this time it is a successful startup. Is this a Yosemite bug or do I have a virus? I also have some funny tiling on the screen at youtube and some other websites. Another bug?
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

was recently sent a very large emoji message amd now when i try to acces messages it will not display mesagges and then will bring me back to the home page
Quit the messages app and reset your phone.
Go to the Home screen and double click the Home button. That will reveal the row of recently used apps at the bottom of the screen. Tap and hold on the app in question until it jiggles and displays a minus sign. Tap the minus sign to actually quit the app. Then tap anywhere on the screen above that bottom row to return the screen to normal. Then restart the app and see if it works normally. Then reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart.
After the phone restarts go into Messages and delete the thread containing the problem message. -
