MacBook Pro :: LCD Not Working Backlight Working And External Work?
Apr 11, 2010
I have tried a few thinsgs to try and get it to work including reseating the cables and that has not helped. As the title says, the back light works as i can see the screen getting blacker/greyer. Also the external output works as well. I'm not sure what to do at this point because I can't find information on an inverter board for the LCD, only the LED backlight think this could be an issue with the video card 8600M or is my LCD dead and I need a new one?
On a side note I have taken very good care of this computer, no drops, making sure the HDD is parked before moving, having it in a protective case, etc. The only difference is that I gave this to my sister to use and after a few days it died. (seems everything she gets that's electronic dies these days, meaning I probably shouldn't give her anything that has a circuit board in it....)
i dropped my macbook. The screen was not responding any more but the backlight was still working. Now, i have opened up my macbook, because my insurance company gave me a new one. There is nothing i can see that is changed. So what is the problem here? I am not waiting to bring it to the store with a respond: It will cost you a 1000 dollar.
After a little spill of coke, my keyboard becomes sticky. I bought new one from ebay and replaced it. Everything works fine except keyboard backlit. I tried basic solutions such as SMC reset, check cabling again but not worked.
i behaved very politely while disassmbling and assembling but now i start to suspect that kill backlit somehow.

I was drinking some tea and bumped into the table the mug was sitting on. A couple of drops splashed out and got on my unibody macbook pro's keyboard. I quickly wiped it off and turned off the computer. I let it sit for a while, but I didn't think anything of it because it was only a few drops. I turned it on and it was fine, however the keyboard's backlight is dim on the right side of the keyboard.
Well, after my keyboard backlight going out, and me looking for multiple solutions, I've found multiple solutions on the internet that include deleting the com.apple.iokit.AmbientLightSensor.plist file from the Library file. My issue is, I'm actually missing this file from my Macbook pro, which leads me to believe that this is the main reason that my backlight isn't working. Is there anywhere I can find this file, or any reason why I'm missing this?
Just to add in, I have a corrupt Hard Drive, and plan on fixing it soon. Could that have anything to do with it?

I own a MacBook Pro 5.1 (late 2008) and since a couple of hours my keyboard backlight suddenly turned off and I can't reactivate it anymore. When pressing the corresponding buttons which regulate the intensity of the backlight I get only the backlight icon on screen with a not available button attached to the lower corner. Is anyone familiar with this problem by chance? This happens under both OS X as well as Windows XP.
The backlight for the keyboard on my powerbook G4 isn't working. It worked perfectly a few weeks ago. Now when it is completely dark in the room and I turn the backlight all the way up the keys dont light up. Do the backlights on these keyboards really break?
I'm yet to figure out a pattern, but my Macbook Pro's keyboard will just stop working for several minutes at a time at random points in time...Even if I hit caps or num lock, they don't turn green. Sometimes it'll just happen once every few hours, but I was in class the other day and it would work for a minute, then not work for a few, than work for another minute, etc.
F3 and my right shift key have suddenly become play/pause keys in addition to their original functions. My F8 doesn't really do anything anymore and does not even light up in Keyboard View. I've tried to use Sizzling Keys, and reset Keyboard Shortcuts but the problem still persists. It seems to affect most music playing programs (iTunes and Vox. I have a Macbook Model 5,2 and Mac OS X 10.5.8
I recently spilled a protein shake over my mb pro. It spilled on the right side, but I quickly cleaned it with a wet tissue and dried it up. The problem, now, is that the illuminated keyboard isn't working..only a few random keys are working and the rest aren't..
What should I do? I have a 1 year warranty left, but I'm not sure it'll be covered.
I've noticed that occasionally my IR sensor stops working, and no longer responds to changing the volume, skipping the track in iTunes, etc. It can be resolved by going into Security prefs, disabling and re-enabling the IR sensor. This is annoying, however, and I'm wondering if it's a known issue that might be fixed.
I noticed that when you disable and re-enable the IR sensor, the last few remote button pushes you made while it was broken come through in a burst.
My Late 09 MacBook Air has been working a treat, not a spot of bother. All of a sudden, about 5 minutes ago, I've gone to go online to download some research papers (I'm *trying* to write an essay) and it won't load anything. Not even my Twitter app. It is connected to the right network, which is working absolutely fine on every other device in the house (windows computers, iphone etc). I've turned it off and on twice, the way that us clueless folk do.. now I don't know what to do.
I have a macbook pro (i7) 13'', everything was working properly, but out of a sudden the keyboard is dead & won't respond to anything, now I can't login. I restarted it many times but still the same problem.
I have recently purchased a cricual m4 256 gb ssd for my MBP mid 09 15''.i have installed lion, on it is have reset the ram, enabled trim (also disabled trail an error), sms and so on apprently it is not working.Most of the time i experience beachballs and lags for 30 sec to 1 min. i find it very fustrating, so i unplugged the ssd and plugged it to my mac with a usb. it is now working fluent but not as fast as it could but with 36 mb/s in writing speed and read speed. compared to 10-15 mb/s before. i am aware that it should perform a lot faster. what is wrong? i know it is not the ssd.

I am trying to hook up an external monitor to my mid 2010 MBP. I used a Logiix mini display port to DVI, and then DVI over to the monitor. The monitor is a Samsung Syncmaster EX2220. When I turn everything on the monitor says "check cable" which everything is brand new and I don't have spares on hand to try. My MBP screen flashes quickly like it does when I have hooked up other external devices, TV, or projector except nothing shows up on the other monitor. I have tried to change resolutions but again nothing, installed all updates, restarted both devices and reset PRAM. One other thing that I noticed is the monitor comes with a cd that has a windows device driver. I searched but could not find a mac device driver, yet on the monitor specific webpage it says its mac compatible. It appears to me that the monitor is simply not receiving any signal from the MBP?
After I updated my Macbook Air to Yosemite, my 2T Lacie Porche Design External HD kept ejecting after a minute or so after being plugged in. I tried all the troubleshooting there is to try in this site. I took my macbook to an Apple store with the HD and was told the HD was faulty. Then took the HD to Best Buy and GeekSquad said they tried it in many devices and said the HD had no issues. So yesterday (as of the day of this post) I did reset on my mac to factory settings. It reverted back to Mavericks. I plugged in the HD and voila! No issues. So I thought that erasing everything on the mac might have solved the issue. Once again updated to Yosemite and boom. HD ejected. What's the next step?
I just upgraded to snow leopard and when I try to plug in my external hard drive I get a prompt saying "the disk inserted was not readable by this computer." It was working before when I was running leopard.
My MacBook Pro is fairly new, but I have a 500g Western Digital external hard drive that was originally hooked up to my previous computer, a PC. When I plugged in my external, I was able to move files from it to my Mac. However, I was unable to delete files off of the external while it was plugged into my Mac and I could not add files, either.
When I booted up my old PC and plugged the external into it, it worked fine. So I can only assume that since I first used it on my PC, I'm having trouble using it on my Mac. A friend of mine told me something about how I'd have to reformat my computer and start over. PLEASE tell me this is not the case. Does anybody know a way to fix this that lets me keep my Mac as is and not have to delete anything?
i have this headset (without USB connector): [URL]and a adapter that allowes unifies the two 3,5mm connectors (3 pin) to a single 4 pin connector.under mac os x everything works fine: headset and microphone work excellent.but other situation under windows: only headphones work, external microphones don't.
Few days ago I used my Buffalo external HD and it was working fine. Today I plugged it in and it didn't show up on my desktop as before. It's running tho cause I could see the light from it and can hear it been reading but the MacBook is not showing it on the desktop and it has a lot of my important stuff.
I have an hitachi external hard drive. It has always worked up until yesterday with no problems. Today it has stopped working with my macbook pro and my works hp laptop, it will still light up and I can hear that it is turned on but it won't appear on the screen. I cannot find any trace of it on my macbook, I've tried the disk utility but it is not there. I tried a friends hp laptop and it is working fine on that.

I'm using a MacBook Pro 13" Mid 2012 (no Retina) with an external keyboard (Apple A1243 USB). I was using Mountain Lion.
One month ago I was suffering a problem that both shift keys of my external keyboard were not working properly. Only if I press both shift keys simultaneously they worked. But, also other keys were activated (e.g. "e" and "r" or "5" and "6" on the number block). The keyboard works fine on differnet computers.
Only a full system recovery solved the problems, meaning this is a software problem.
Today, I'm facing the same problem again and don't want to do the recovery again.
I tryed this steps: One or more keys on the keyboard do not respond
I have an Unibody MacBook. I've experienced that under OS X "Tap to Click" function of the trackpad stops to work after "some" usage. Then I go to System Preferences, disable the feature, reenable it and it starts working again. OS X is updated and firmware updates are all installed.
