Early 08 Macbook Backlight Issue

The backlight on my macbook has been acting very wierd lately. It is now turning off at random times, however, if I bring the brightness all the way down to zero and then raise it again the light comes back on. The screen works the whole time, just no backlight. I tried resetting the PRAM and then the SMC and both seemed to make the problem go away only for it to come back later.

Unchecking "Automatically reduce brightness..." in the Energy Saver Preferences fixed this problem for me.
Original Symptoms:
Turn on Macbook, screen becomes fully lit through the apple screen, then dims completely when the OS begins to load. The display can be seen slightly using ambient light, but the backlight is completely off.
Temporary Fix:
The temporary fix was to dim the screen using the function key, then brighten one or two levels. Brightening any more would cause the backlight to go off.
The Cure:
After unchecking the "Automatically reduce brightness..." boxes (in both Battery and Power Adapter mode), I was able the turn the brightness up completely without any other changes or need for a restart.

Early 2009 MacBook backlight inverter problem?

My early 2009 MacBook is having a bit of trouble with the display backlight. Nowadays in order to get the backlight to turn on I need to fiddle around with the display until it comes on, then I have to keep it steady or it may go out again. I have traced the problem to the backlight, because when my screen blacks out if I look real closely or shine a light on it, I can see the stuff on the screen.
I know this can be fixed. I do not want to risk opening the MacBook to do so, because I could probably break something (this once happened when I attempted to repair a PowerBook G4; I wound up disabling the Wi-Fi.) I did hear from someone who had the same problem with the same model early this year, he took it to his nearest Apple Store, and even though it was no longer under warranty, it only cost $45 for the inverter to be replaced! (It also had a chipped palmrest and that helped with the fee too; mine has a somewhat chipped palmrest as well.) Does Apple really do something like that, or would I be better off with a local computer repair shop?
Plrease reply ASAP

The inverter regualtes the power to the back light, i had macbook 2008 inverter break on me and attempted the fix myself. £10 ($15) for the inverter on ebay and about an hour of my time. The reason its a tricky fix is because the inverter is in the hinge of the screen so the whole screen needs to be removed! as i put it back together i was silently praying that i had put everything back right!
it worked fien though! i no 2 year ago when the original owner of that mac took it to be looked at they quoted her £ 150 ($230) to have it fixed so its good to see the price has come down for you!

Macbook backlight issue

It seems like every other LED is dead on my macbook pro. This is the second macbook pro I have received from apple. The first one I bought lit on fire. The magsafe nearly burned my house down due to overheating, melting, and bursting into flame. After all the trouble of getting it fixed and still having issues, they sent me a new macbook pro.
It seems odd that apples flagship computer is such a pile of garbage, and that the screen can't even stay light up. If i knew how to post pics on here I would, but until I learn they will sit on my cell phone. Last time I complained about my computer LIGHTING ON FIRE an apple tech called me before I had a chance to get ahold of them. I hope I get the quick reply I deserve and they RESOLVE this problem or I will NEVER in my life buy another mac product again. NOT for home, not for work, or anything else.
Spending 3000$ on a computer seems strange when an ACER that costs 300$ can actually keep a backlight lit on its screens.
Is anybody else having this problem? I searched it on google and it said it happens often

stuff fails, sounds like you've been very unlucky, but apple sells millions of units, most are fine otherwise apple wouldn't still be in business
we've got two powerbooks, two macbook pros, two macbooks and two imacs, only one hardware failure in 7 years - fixed under warranty - and all are still running well
the best thing to do is call technical support and arrange for repair/replacement...

2007 MacBook Backlight Issues?

Hey everyone,
My old, faithful 2007 MacBook has just encountered a spot of trouble with its backlight. The backlight is off/ on the lowest setting and unresponsive to commands via the brightness control keys and changes within system settings. When restarting the computer, the light is functional for a split second before reverting to total darkness.
Both reseting the SMC and the PMC (?) have proven fruitless (removing battery, holding power for 5 seconds, re-inerting battery and restarting computer as well as pressing alt+option+p+r upon restart).
I am trying to get a hold of a cable to attempt hooking it up to an external monitor to see if that works (seems some others on the forums have had luck with it). If not, will I be looking at needing some hardware replacements? Or are there other methods I can try?
Thanks in advance for your time and help - I really appreciate it!

Thanks for the reply - i will give them a call, alternatively will try sourcing the item my self. I have had a few problems in the past with this particular MacBook, they are as follows:
- Keyboard Replaced (Under 1yr Hardware Warranty by a AASP, they fitted the older version keyboard with the Apple logo)
- Bottom case replaced due to hairline cracks. (Under 1yr Hardware by AASP)
- Hard Drive replaced (At an AASP)
- Bottom case bezel + keyboard replaced again (AASP, fitted incorrect keyboard again)
- Graphics related thing replaced to solve multiple colored lines vertically on screen (AASP)
- Bottom case bezel + keyboard replaced a third time (Apple store, correct keyboard placed back on - No warranty)
- Screen surround (white bezel) replaced (Apple Store - no warranty)
The battery had also died at the last point, they didn't mention it at the Genious bar, but when i got it back they had given me a brand new battery (not even mentioned in the documentation)
Is this an absurd amount of things that have been replaced within 2 years?

Early 08 MacBook charging issue?

Hiya,
     I recently purchased a black macbook off of eBay. I fixed an issue with the hard drive structure (white screen of death) and it's a neat little computer. What I did notice was a problem were the batteries. This computer came with a black and a white OEM battery, both of which had rapidly 1 rapidly flashing green light. I had thought that this meant that the batteries were almost completely decharged (MacBook Pro does the same thing when on reserve battery). I took it to the apple store to get checked out, and the diagnostics showed that the black battery (didnt have the white one with me) was in the green (normal) section, and that it wasn't a problem. The Geniuses discovered that the component of the computer that charges the battery was faulty and needed to be replaced. When I went to go pick up my computer from the repair today, I noticed that the black battery inside it didn't have any flashing lights (when the indicator button was pressed), and assumed it was completely uncharged. I borrowed a charger from one of the computers on a personal setup table (it was a T-style), and the battery had the 10:00 (0%) until charged issue. The light on the charger was orange, and the indicator on Leopard shows that the battery was charging.
     What's interesting to me though is that when I took it home and left it plugged in (L-style MacBook Pro charger, 85watt, was told it was ok), it charged for around 10 mins, then the light turned green, and the status bar says (0%, Battery is not charging). When I check the level of the battery with the button, it flashes the single green light again. I charged the white battery and got the same results. The black battery has around 650 cycles and the white battery has around 720. I downloaded coconutBattery and did some examination, and found that both batteries have an Amperage of -1, but both still have 91% of capacity (lifespan is my guess). I can post pictures of the coconutBattery/system reports from both batteries, and both are listed by system profiler as in Normal Condition.
     I did run software update on this recently, and the only things that can be updated are applications, java, etc. This macbook is running Leopard 10.5.8, and has the 1.4 (1.31) firmware installed for the use of L-shaped power adapters. The power adapter works fine and charges the battery on my MBP, but unfortunately it's the only adapter I have to use at the moment. I have reset the SMC and NVRAM numerous times to no avail. If you have any info about this, please post.
Thanks!

What's odd is that after pressing the MagSafe adapter into the computer (with pressure), the light changes from Green to Orange and says it is charging. It has been in this state for 10-15 minutes, and hasn't risen from 0%. The white battery doesn't charge at all. I tried resetting the PMU and PRAM again to no avail. What I notice is that as soon as I plug in the adapter, it turns green and doesn't charge the battery. However, once I press the adapter into the socket, it turns Orange and says it's charging.
The battery info says that the battery is taking in 0 mAh, so I'd be lead to thinking that it's a glitch with the power system that tells the adapter the battery is being charged

MacBook Pro 13" Early 2011 - External display issues

I have an early 2011 MacBook Pro 13" (2.7GHz version) that I am using with an external non-Apple display. I am having issues when MBP goes to sleep or trys to sleep the display. The external display exibits one of a number of problems: goes dark but does not power off the backlight or freezes up and requires being powered off then back on. My display is an ASUS VW266H but it seems like this problem, or other similar problems, are happening with other non-Apple displays.
In calling Apple tech support of 5/27/11 they indicated that this is a known bug and they are working on a fix. There was software update released 5/4/11 to "improve graphics stability, address issues with external display" named MacBook Pro Software Update 1.4 (http://support.apple.com/kb/DL1382). I downloaded this and applied it but it made no difference.
I experienced these problems with three different video adapters: Apple's own mini DP to DVI, Belkin mini DP to HDMI and another brand of mini DP to HDMI also sold by the Apple store.
So the questions are:
1) Will Apple release another updated to address this incompatability or are they done with the issue given that they released the update mentioned above?
2) Has anyone compiled a list of monitors that are know to work with these most recent MacBook Pros (the early 2011 versions with the Thunderbolt/mini DP combined ports)?
If you have used the MacBook Pro 13" early 2011 with an external monitor please respond to this post with your experiences so we can all know what works.

With my new 2011 13" MBP I'm having no latency issues using my '08 Samsung SyncMaster 2253BW DVI (digital) monitor. Sleep function awakens fine, goes to sleep 3-4 sec.
I'm using a cheapie model Syba MDP to DVI connector; here on Amazon:

My MacBook Pro 2011 model has a backlight issue- pls someone help

I have a early 2011 MacBook pro that has a backlight issue, im able to connect it to an external monitor just fine.
Brought it to a repair shop and they swapped the screen including the lvd cable but the problem still exist.
Have already spend a lot of money to no avail. What could be the issue? :(
Apple said it only needs a new screen which doesn't seem to be true.

http://support.apple.com/kb/TS1713
It is under warranty https://selfsolve.apple.com/agreementWarrantyDynamic.do
If it is more than one computer and both chargers are not working I suspect you need to replace.
If it was just one Mac I might suggest reset SMC http://support.apple.com/kb/ht3964

Bootcamp windows 8.0 pro installation issue with early 2015 Macbook Pro

I am having this issue with installing Windows 8.0 pro (and 8.1 pro) on my early 2015 MacBook pro vs. Bootcamp. I have tried different method for multiple times and all failed. Any help is appreciated.
Hardware: (1) early 2015 MacBook Pro with 128GB (13 inches) , (2) Sony USB DVD burner. (3) Two 16 gb flash drive 2.0 version from two different manufactures
Software: (1) 8.0 Pro ISO on flash drive from Microsoft (I have two copies) (2) 8.1 Pro downloaded from Microsoft website.
Note - I was able to download the bootcamp supporting files successfully and copy to a USB flash drive.
Method 1 - Create the installation disk from ISO on flash drive and also tried copying ISO on hard drive (desktop)- failed.
I have a 16 GB flash drive (2.0V) connected
ISO is a valid 8.0 pro copy from Microsoft came on a flash drive.
I have the windows 8.0 pro ISO on a flash drive and plugged in.
Issue - It gets to around 50% of "Copying Windows files..." and then doesn't go any further. 8 hours later, still stuck at around 50%. I also tried to do the copy ISO from desktop. failed as well.
Method 2 - I repeat the above steps with Windows 8.1 ISO downloaded Microsoft website - failed. Stuck at 50% copying windows file for 9 hours.
Method 3 - I burned the Windows 8.0 pro ISO to a DVD and try to do the installation through a DVD instead. DVD was successfully created.
I was able to perform the partition. When the computer reboots, it starts the window installation. However, it got stuck at 7% forever. I tried this multiple times and failed.
Method 4 - I download a 8.1 Pro ISO from Microsoft website, I burned it to a DVD. Repeat method 3, Again, windows installation stuck at 7%.
Method 5 - I called Apple. - What they told me is pretty much repeat the above steps. Still failed.

The ISO file(s) being downloaded seem to be corrupted. Can you use Microsoft FCIV tool - https://support.microsoft.com/en-us/kb/841290?wa=wsignin1.0 ?
The DVDs should be burnt at the recommended rate for the physical media. DU should be used for burning the DVDs.

I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. What can I do?

I am using an early 2008 MacBook Pro and am having issues with it deleting text on its own (in word, emails, etc.). As I am typing it all of a sudden starts deleting and I can't stop it. This happened once before and it was due to a buldging battery pressing on the track pad. I checked the battery and it appears to be fine. What can I do?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Black macbook backlight display issue

im working on a friends macbook. the issue is the display. the laptop boots up just fine but after laptop has powered up the screen stays dark. the battery is charged. when the "f2" is tapped once the display lights up a little. when pressed again it goes back to dim. i then have to press the "f1" key to bring down to the lowest setting. i do this all over again some times i can get to around the 3rd brightness setting then it automatically drops to dim. i assume the backlight bulb itself is ok so am i right in saying the inverter is going bad or is there something in the "f1" "f2" keys that is not making a good connection. I hope i explained this well enough. Thanks.

Actually, I don't think you can hook up the USB to a RGB cable.
Wich imputs does your projector support? VGA?
If your projector supports VGA imput you can use a displayport cable with VGA exit and plug the projector there.

Sound Issues with early 2008 Macbook Pro

I have an early 2008 Macbook Pro with Mavericks that has suddenly developed a static and clicking sound through the internal speakers. The static and clicking sound does not occur when using headphones. Is this a speaker failing or due to some other reason?

If there is no success with a PRAM reset, make an appointment at an Apple store genius bar. The evaluation will be FREE regardless of the age of the MBP.

Early 2008 MacBook Pro - no chime, no video, sleep light solid

Have here an Early 2008 MacBook Pro, 15", 2.5GHz. It's in good physical shape... shows no signs of spillage, being dropped or mishandled, etc. I know virtually nothing of its history.
The machine will charge the battery. When I attempt to turn it on, I hear the fans and drives do their thing - but I get no video (internal or external, not even the backlight) and no chimes or tones. The sleep indicator light turns on and stays on, solid white.
Tried the SMC reset proceedure outlined here (remove battery, hold power key 5secs, reinstall battery and try again) - no effect.
My gut reaction is bad logic board, but wanted to check here before giving up on it. Anything I might be missing?

I've worked extensively with the older PPC (and, dare I go back so far, 68K) machines, just not up on all the common issues and techniques for the Intel-based Macs. This seems hardware-y to me, just want to make sure I'm not missing something relatively simple.
Pressing D (or any other key/s) doesn't have any effect, as the machine isn't making it that far into the boot process.
EDIT: the message above was posted as I was typing.
I was afraid it could be that... heard it to be a common thing, but never seen one do it in person. Too bad the warranty extension just ended a month ago, else I would have had more motivation to make the trek to the Genius Bar.
My strong suspicion that it's a logic board issue, and that I've got myself a fancy aluminum paperweight, is getting stronger.

Is there any way to make a snow leopard partition on an early 2011 MacBook Pro that was upgraded to Lion, without the original boot disk?

So I have an early 2011 MacBook pro, I believe it shipped with snow leopard originally, as I purchased and upgraded to Lion fairly early on. I am trying to make a partition right now and have it run snow leopard so I can use programs that have PowerPC.
I should note, I replaced both the RAM and the harddrive in my Macbook pro. I changed from 4 GB of ram (that came shipped) to 8 GB of ram from a 3rd party, that I installed on my own months ago, have registered in the computer and have been working fine for quite some time now.
Also I should note I replaced my harddrive. I went from what ever the standard 500 GB harddrive that shipped with 15 inch early 2011 MB pro's. I now have a 3rd party SSD that's 240GB's that I also installed on my own, (at the same time as the RAM---Black friday items) The harddrive has been working just fine since then.
In installing the harddrive I borrowed a friends external harddrive and used a program called carbon copy cloner to get everything over to the SSD.
Now here is my issue. I have ordered the Snow Leopard (10.6.3) install disks from apple, I have created a partition on my SSD for snow leopard, but when I try to select the install disc for snow leopard at boot I get three beeps.
I know this issue has been posted elsewere but it said answered and the answer is no longer available. I also am unsure if any of the RAM or Harddrive swapping could have been causing the issue. I have the old harddrive and RAM still, but unfortunatley have no external harddrive anymore or money to afford one.
Is there any way I can install a partition that runs snow leopard on my early 2011 MB pro with what I have (new SSD, New RAM, Current version Lion running, no external drive, lack of original snow leopard disks [I lost them ] and the general 10.6.3 snow leopard boot disks).
Let me know If there is anything I can do. I'm a now broke college student so i'd like to spend as little $$$$ as possible
*PS I should also note the DVD drive is working fine, it reads the disk, the disk is brand new, it plays DVD's fine and has never had any issues in the years i've used it for similar tasks*
sorry for the long drawn out post, I just wanted to include as much as possible from what I've seen other people have issues with

As the last post suggests, call Apple and order a replacement original disc for about $17. They will ask you the model and serial numbers.
Your retail version of Snow Leopard OS 10.6.3 will not work on that Mac as it requires a minimum of OS X 10.6.7 to boot and operate.
Another alternative is to again borrow another Mac to install your retail Snow Leopard into an external HD or partition, upgrade it to 10.6.8 and then clone it back to a partition on your MBP.

Early 2013 Macbook Pro Retina 2.7 i7 512GB SSD and 16gb Ram with Serious Cuda Problems! Trying to teach Apple their Macbook Pro Retina isn't a Pro Jan. 11. 2015.

Apple replaced the logic board, wiped the computer, did a fresh instal of the OS, and also a fresh instal of all the programs during the beginning of 2015. The GeekBench scores are the highest of any of the similar computers (at least on the day of my testing). But here's what's happening. The Macbook Pro Retina has a GeForce GT 650m with Cuda Technology and it can't handle editing in Premiere Pro with Cuda Acceleration turned on. Open CL, a second form of graphic acceleration on the Macbook Pro, appears to be functioning properly.
At the Apple Store on 1-10-2015, I was told that since the logic board and the graphic cards have been replaced that there is nothing they can do and they recommend contacting Corporate. This comes after they told me to buy a new logic board and that that would solve the problem. This comes after Apple did not listen, for over a month, about the possibility that they didn't properly build a professional notebook computer.
The computer displays a black program monitor screen, at random times, when the user edits footage with Cuda Acceleration enabled. It used to lead to an entire system crash and/or a Premiere Pro crash before the operating system was completely re-installed. My solution, since I bought the computer, was to edit in Open CL... However, I've come to learn that there is a major difference in performance between Open CL and Cuda Acceleration.
For the Macbook Pro Retina, Adobe Media Encoder render times are about 20% faster with Cuda Acceleration than Open CL. The 2013 Macbook Pro Retina appears to be able to handle Cuda Acceleration in Media Encoder, but I have had a number of issues leading to program crashes on every project before the new logic board and operating system were installed. For over a year and a half, I actually never used Cuda Acceleration. Having sent every crash report and user data to Apple over that time, I truly expected an update of some sorts and it never came.
FYI: The latest Macbook Pro Retina uses the GeForce GT 750m... This is essentially the same graphic card that performs about 10 - 20% faster due to a new "boost mode." More importantly, it actually has the exact same number of Cuda cores. Having the same number of Cuda Cores means that the Cuda Acceleration is essentially the same when exporting or viewing video. To prove a point to Apple that their 2013 Macbook Pro Retina isn't functioning properly, I bought the latest computer with the 2.5 i7, 16gb Ram, 512gb SSD and I can honestly say that the 2014 model works perfectly fine with Cuda Acceleration turned on while editing in Premiere. I can also say that a proper render test proved the 2013 and 2014 model to be the exact same.
I'm new to this whole pay $2700 for a computer that your manufacturer didn't / can't test properly, so I will be contacting Apple and speaking with Senior Advisors, their Customer Support division, and will soon speak with their Corporate branch. I'm confident that the Early 2013 Macbook Pro Retina with a 2.7 i7 16gb Ram and a 512 SSD is nearly the same at rendering video and editing video, provided the Cuda Acceleration works, as their latest 2014 Macbook Pro Retina with the 2.5 i7 processor 16gb Ram, and a 512 SSD. It's truly a great computer and a great build, minus their current inability to properly test / diagnose their computer.
Knowing that the latest graphic card in the Macbook Pro lineup is essentially the same model, I feel that Apple is not directly looking into the viability and life span of their current Macbook Pro Retina product line. They can't test for performance issues relating to their graphic cards, so why consider buying from them when the end user is actually in a position to experience up to a 20% decrease in certain professional programs.
For future reference, I'd strongly urge other individuals to avoid purchasing Apple products if they offer Cuda Technology. In my opinion, Apple is an Open CL organization, at best, who is not responsibly manufacturing / producing computers that fit their organization's strengths. For a fact, they can't test their Cuda Technology and won't even attempt to address Cuda Acceleration errors for Apple owners (01-11-2015). I say this having walked out of the Apple Store on 1-10-2015 with virtually no support other than to contact Corporate.

Tried the "Apple Bake" on my early 2008 macbook pro and it worked, does that mean for certain it is my Nividia chip that is bad?

So I had my early 2008 macbook pro (A1260) not wake up after clamshell sleep. After researching the boards felt confident it was the logicboard issue. Not being able to afford a replacement I decided to try the "apple bake", as I have been employed as a maintenance tech for a corrugation company and was comfortable doing the work myself. Anyhow it worked (350 degree f - 8mins) and my mac was back to life working as normal except for the fans running at %100 all the time. The fix was short lived, only lasted about 5 weeks and wouldnt wake up from sleep again. (yes, I applied new thermal paste the first time haha) I did the bake again and again it was revived this time fans working properly (still not sure what that was about) I have since had to do it one more time and now I just dont ever close it or let it go to sleep. I found a guy online who will replace the gpu for a good price ($150), my question is, is it actually the Nividia chip thats the issue and not something else? Is there any other issue that would be reolved by doing the bake and Im just thinking its the faulty 8600 geforce chip?
Macbook Pro 4,1 - 10.6.8 - 2.6ghz Core 2 Duo - 4gb 667 Mhz DDR2 SDRAM
Other issues I had aside from not waking up from sleep
-Strange feedback noise coming from speakers in between any audio being played. (intermittent) any audio will stop the noise. (might be unrelated)
-Dark lines from bottom of screen to top. Screen reset will fix (shift+cntrl+eject)
-Pixeleation when gaming (intermittent)
Any help would be appreciated,
Thanks in advance
