View 2 RepliesI have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.
I kept my macbook (late 2008) turned on overnight on lowest brightness and when I tried turning the brightness back on this morning, the backlight flashed on for less than a second and then turned off again. Somehow I managed to get it to work, but whenever I move my macbook even slightly the problem reoccurs. I've done some research on my problem and I suspect that it's hardware related (maybe the inverter or the inverter cable?), but maybe the LCD itself is broken? Does anyone else have any experience with this?
View 1 Replies View RelatedI have a 2.2 Santa Rosa 15" MBP, and an odd thing happened last night. I wasn't running any unusual applications, and had a few things open and was browsing in Firefox. All of a sudden my screen went black, and wouldn't come back up.
The computer is still running just fine, and it didn't go to sleep. The LED backlight is fine, as the Apple logo is lit up and if I change the brightness I can see the backlight changing (the "black" screen gets less "black", if that makes sense), however the actual display panel isn't projecting any picture at all.
I've restarted a dozen times, reset PRAM, and did the unplug battery and hold power button trick, all to no avail. There's no flicker of a picture or anything... it's as if the monitor is completely dead (aside from the backlight being fine).
If I plug in an external monitor, I can use the computer just fine. So it's not like the video card is dead all the way.
I know that the base 2.0GHz MacBooks do not feature the backlit keyboards of the higher-end models, but I was wondering if the actual backlight is physically in these lower-end models and just disabled in firmware or software? Or is it missing entirely?

I have a Macbook Pro (Newest gen.) and sometimes the keyboard backlight wont turn on. I suspect it to happen when I have had the Macbook on standby, but I don't know for sure if that is what does it.
Then i press the backlight-adjust buttons on the keyboard, this OSD-symbol turns up: http://peecee.dk/uploads/122010/Scre..._big_thumb.png
The backlight on my MacBook went out suddenly today, no idea why. Is there some way to replace it without having to replace the entire display assembly? It is very difficult to get the assembly apart, but I will be on break from school and will have plenty of free time to fix it if it will save me a few hundred bucks. So is it possible to replace the backlight only, or is it a part of the lcd panel?

View 7 Replies View RelatedI have a 2008 White body model Macbook with 2 gigs of ram and 2.1 core duo processor. My problem is that the screen won't turn on...when I start up my computer it lights up for a second, but turns off before the apple sign shows up. If I look really close I can see everything. Oddly enough, if I press the brightness button so to decrease the brightness to the very last bar and then hit the f2 button to turn up the brightness by one, the light will turn on for a few seconds, if i continually go back and forth, I can sort of use it enough to do something with it (thank god because I had all my work for school on it). I have included a link with this thread so you can see what I mean.

View 13 Replies View RelatedAt full brightness the flickering is barely noticeable unless you really tried to look hard for it but you can also see it on website backgrounds with lots of lines, such as the left sidebar on [URL] Also, when the backlight dims after being left alone, the backlight flickers for a couple of minutes and then disappears. I have had this macbook for a bit more than 2 weeks. Should I send it in for a repair/replacement?

1.) Is there a way you can make the keyboard's backlight become brighter in low light situations?
2.) Is there a way for the backlit keyboard to turn off in lit rooms and turn on in dark rooms?
For some reason the backlit keyboard becomes dimmer in low light situations. I'm finding it really irritating. I have a feeling this is the way it is suppose to be so that the keyboard doesn't blind you. Any programs to hack the light sensor?
I have had my Macbook for almost three years now, and for the last month, the backlight for my screen has gone off. However, when I put the brightness down to 0 when the light is off, and put it up by 1 it sometimes turns on for a couple minutes/seconds/hours. Any help? By the way, I am using Boot Camp, I do not know if this happens on my Mac Side, because it comes up with a "stop" sign when I try to boot it up.

I have tried a SMC reset 3 times, I have tried deleted the plist file and I have tried the finger over the isight lens and nothing is working.
The buttons work fine and it increases and decreases on the screen, it is just there is NO LIGHT whatsoever!
I don't know what else to do and don't want to send my laptop off to get fixed if it is just a simple thing I can do.

For the first time last night, I was using my new 13" MBA ultimate and noticed the keyboard back light was not working. Is the some way it has been turned off, and if so how do I turn it back on?

I was surfing the web when my keyboard backlight started to fade on and offat somewhat regular intervals. After about a mintue or two of this, the backlight just went off all together. Now, when I press the F5 or F6 key to brighten or dim the keyboard, the keyboard backlight does not respond. The usual screen pop-up that shows how bright or dim the keys are no longer increases or decreases but shows the symbol of O with a slash through (like the no smoking symbol).

I own a macbook pro unibody A1286. I spilled some soda on it and I followed everything that you would do when a liquid spill happens. After a few days I turned on the macbook pro and I hear the charm and can see the screen with light on it. The back light had gone out on the unit. At first I thought It would be the screen, so I ordered a new screen and tried it out. With the new screen it is the same, the back light for the lcd wont turn on. Everything else on the macbook pro is functional except for the back light.
I even own a mini display port to HDMI adapter and hooked that up to my TV and it worked perfectly. The isight camera works, all the ports work, speakers work, optical drive works. Just the Back light on the LCD does not.
I've installed OSX successfully many times but this one, with a new WD disk gives me trouble. After the gray screen is gone and the installation menu starts, the back-light turns off and I can't do anything about it. Any idea why that happens and how I can deal with it? I am working on a Mid 2009 13" Macbook pro with 2.26ghz and 8GB of RAM.

View 2 Replies View RelatedMy keyboard backlight isn't working... whenever I try to turn it up it gives a circle with a line through it. I have read that there is an ambient light sensor that turns off the keyboard backlight when it is too bright, however that has NEVER happened before and I have used it in direct sunlight and the backlight still obviously works. It's not even bright right now but it won't work. This is very frustrating, there should be no sensor that turns it off it should be the brightness I tell it to be.

My backlit keyboard has recently started to act up. It has recently started at random times to not let me manually adjust backlight at all, randomly turning it off and disabling the two buttons to adjust it. It is a Unibody MacBook 2.4
View 4 Replies View RelatedI've had my new 13" MBP for about a month now and I am noticing what looks like backlight bleeding spots at the bottom of my screen. It is most noticeable on the bottom left and appear blue-ish on a black screen at maximum brightness. It is getting irritating when I am watching movies at night. I have the 9CBD screen. Others have said they have no problems with this screen model. So is this normal or is it a defect? If it is a defect, what can I do to fix this? My 14 day grace period is over, so I'm assuming an easy exchange at the Apple Store is out of the question?
View 6 Replies View RelatedJust got a new MBP 15" AG this week and was wondering if you can adjust the sensitivity of the keyboard backlight. It seems to come on even in a fairly well lit room and I mainly only need it in a completely dark room. So I find myself hitting the backlight keys to turn it off and then whenever it wakes from sleep goes back to full bright. Didn't find anything in the keyboard preferences and found a program called Lab Tick which will take care of the level on wake.
