MacBook :: Potential [Permanent] Back-light Failure?
May 12, 2012
I got a 2008 MacBook that has a misbehaving backlight. Just recently, the backlight refused to go on for any amount of time.Toggling the brightness from (0) to (1) bar turned it on for varyings amounts of time lower than one second.I continued to toggle the brightness in this fashion to use the computer for a time.Occasionally, the screen would remain lit for a little over a second and dim again.I changed the power settings from power saving to performance and back to power saving.Then, I opened up Chrome and the backlight remained on.It still remains on, as I am somewhat unwilling to test opening and closing the screen.I can, however, now vary screen brightness fully.tl;dr - Backlight was finicky, but is now functioning normally.I suspect the backlight is going to malfunction completely in the near future.
Info:
MacBook, Mac OS X (10.5.8)

I unplugged my PowerBook and the screen and backlit keyboard dimmed and then brightened back up. Was there a power surge inside my PowerBook?

I have a new 2012 Macbook pro 17 and a 27 inch thunderbolt display.
The Macbook was working great. Then I connected it to the thunderbolt display and did clamshell mode. That worked well too. But.. then I powered down the macbook, disconnected the thunderbolt dislplay and tried to boot back up again. The mac book powers on, the back light comes on, I hear the chime then that is it. The back light stays on nothing else happens. Resetting the PRAM can not be done. Any of the boot options are ignored. It is like the keyboard is non resposive. I tried all the reset and boot combinations available but nothing works.
The light on the front of the macbook comes on then goes dim. The apple logo on the lid stays lit, and if I close the lid, the apple logo goes dim and the light on the front lights up. Weird, it is almost like it goes to sleep when it turns on. I tried conntecting the thunderbolt again but no joy. I am really disappointed. This is less than a month old and its already going in for repair. It should be replaced.

MacBook Pro, Mac OS X (10.7.4), I am disapoint.

So a friend spilled some liquids on his new macbook pro 13 5,5.Unibody The keyboard no longer worked, the hd was fried, so he gave it to me and switched to PC's . I replaced the HD, and connected an external keyboard.
Luckily nothing else was effected and it powered up. What I find strange is that the back light still works although NONE of the keys do. The power button and the trackpad still work as well.
I have accepted that I have to purchase a costly top case, but could i not just replace the keys?

Here's a new one (for me anyway).
2007 MacBook: 2.16 Ghz, 3GB RAM, Intel GMA etc.
Anyway, all of sudden, any motion I make kills the backlight of the screen. In the right light you can still see things and the computer still works perfectly, just extremely hard to see. Have to do a restart in order to get going again.

My 2.2GHz MacBook (3,1) has had an issue for some time now. At first the backlight would flicker as you moved the display from closed to open. The backlight stayed lit through most of the travel. It's gotten progressively worse lately where it will only stay lit at certain angles, and is otherwise black (you can still see the display in sunlight though). Right now it'll only stay lit if I open it very slowly and stop once it lights up.
As I don't have a ton on money to spend, I don't want to just throw parts at it. What could be the issue? Since when it lights up it lights up full brightness and stays lit, I don't think it's an inverter issue. Could it be the inverter board cable?

I finally purchased my dream laptop a month ago and it has been great so far until I ran into this strange issue. It seems when the backlight it set to below 50% and either my hands are on the side/bottom or I'm slightly moving or tilting the laptop the backlight goes into this weird super-bright state for a few seconds. When this happenes there are even brighter circle shapes near the dock area. Problem is this only happens sometimes and I cant seem to replicate it with a certain action. I'm not sure what will happen when I take it into the store. If anyone can shed any light onto similar problem

Just invested in a TC as my MBP had to go in for repair. Got it all set up and backed up, and was working great.
However, having got the MBP back with new logic board, its stopped working.
Backups just fail, and if I open Time Machine, it doesn't see the back ups made before the MBP went for repair.
The Time Capsule shows up in the finder OK, as being connected, and with the .sparsebundle file visible. It also shows up in Airtport Utility OK.

Macbook Pro won't boot. Symptoms preceding failure included failure to open Firefox. When trying to cold boot I can get as far as the start-up sound, the Apple logo, and the spinning whieel (spins for a bit but not for very long) and then major failure. Not running Liom.

This is something that has happened since my initial installation of XP on my bootcamp partition. Whenever the light sensor detects low light, the backlight turns on at full blast. This is normal. However, when I go to turn the backlight off completely (as to save battery or if I'm watching a movie in windows and I don't want to see the keyboard lit up) it turns it down, but not completely off. Even though the backlight indicator claims that it is down the whole way, it never completely turns off. In OSX when I do this, it turns it completely off whenever I set it to the same setting.
has anyone had something similar in their MBP or any ideas of what is wrong? Is it just something with the drivers?

What's the consensus on the MBP and charging?
Should I let it run down before plugging it in or plug it in whenever I can? Does it make any sort of difference to the life of the new internal battery?

Today I started to export my first iMovie project and when I export the movie it seems it is only using 50% of the CPU (looks more like it is only working on 1 core) but when I check the activity monitor it shows it is working on 2.I have an SSD 4GB Ram and Core duo on my Macbook pro.Is there a way to check if the MBP is using its full potential?Right now I can perfectly work and watch movies without interference but the export takes very long, what if I just want to make sure the export goes the fastest?

I was just rummaging through my cupboard looking for me certificates when I found it. And it fit's pretty alright. It will have to do for now. It a case for my Razer mousepad, the Destructor. It's hard on the surface and it'd do a nice job of protecting it over minor bumps but nothing major. What I like about it is that it's slim. When I first bought the Destructor mousepad couple of years ago, I remembered thinking the case would be a good case for laptops. Had a 15" HP that time and it wont fit. Not to mention, it was too thick. Well, I snapped a few pics. And oh, its a 13 MBA if anyone is wondering.

Does Applecare cover the replacement of the backlight bulb and inverter board? Looking at a PowerBook that has Applecare - The screen in the listing picture is not too bright. The seller has stated that all is well with the screen, but you never know. I am prepared to go for it if the Applecare covers the screen lighting. Applecare cover on notebooks appears to be worldwide - If the screen lighting conks out overseas, I can get it fixed at the local Apple Store?

I bought my MacBook Pro in January and quickly discovered that most Adobe products don't work on Lion. I'm looking to sell and have a prospective buyer when I realized that I wasn't sure how to do a clean install of Lion for a potential buyer. Do I need to buy a copy of Lion from App store in order to do a clean install for a new buyer? Is there a way to clean the HD of my user profile and info without reinstalling Lion, or do I need to do a clean install? How do I do a clean install if necessary?

After using a PC laptop for six months or so (and it really messing with my eyesight) I thought I'd try to revive my old macbook. Basically 70/80% of the time it won't turn on. There are these patterns of faulty behaviour which I hope you guys could diagnose:
1. I'll press the power button, I hear the disk noise, and the screen is black (i.e. not a backlight problem). The chime won't sound, I can just hear the fan and the hard drive whirring. The only way to get out of this is to power it off via the power button.
2. Sometimes after it's started up successfully and I move the Macbook (say, from a desk to my lap) the same thing will happen - black screen, with the rest of the stuff whirring, and if I try to shake it around nothing happens, I have to power off.
3. Occasionally when I power on, I just get the disk noise, a white screen, but no question mark, no apple logo, nothing.
4. Another time I tried to boot up with an external hard drive fitted and just got the chime over and over and over. Removing the drive solved this.
5. One time the screen just greyed out and a message in about 5 languages came up saying I needed to shut down my computer NOW.
This is not a hard drive fault - I saw that apple had extended the warranty on the hard drive because the question mark usually pops up for half a second at startup, and the nice guys at regent st London just whacked a new hard drive in, with a clean install of leopard (which was cool, I was previously on tiger at the time). I read something about resetting the PRAM (which I haven't tried), but I'm guessing it's the logicboard/motherboard. If this is the case, any idea how much it costs to fix? (My macbook is out of warranty). Figures in GBP appreciated but I can convert USD estimates. Is there any way I can try to blag a free motherboard and install from apple by exaggerating some symptoms?

Before I go into detail I have a Late 2008 Macbook White (Upgraded to 4GB RAM, 320GB HDD) so I would have had it two years this Christmas (2010) Over the last few months, on odd occasions the bottom row of keys completely stop working (by bottom row of keys I mean: Z X C V B N M < > ? and then fn ctrl alt and CMD on the row below. The space bar and right CMD work perfectly as does every other key on the keyboard.
Now this is where it gets really weird. I always thought this was a hardware issue (Loose ribbon connection etc, I just don't have the hours in the day to sit down and take it apart) until my friend gave me his old aluminium apple wireless bluetooth keyboard (the laptop sized one). The bottom row of my keyboard broke again whilst visiting him so we set up this aluminium keyboard of mine................

I've been trying to find a solution to this for ages, with no success. I'm not even sure it's possible, but I thought I'd continue to try. What I want to do is change the language setting in Pages permanently. I've had answers telling me about the language setting, and International Input menus and so on, but I'm familiar with changing the language setting, as I write a lot of documents in French and in German, but I write more in English, so what I want is to be able to permanently change the setting so that every time I open a new document, the language is set to British English.

Is there a way to making certain settings in the guest account permanent? For example, I would like the setting where you tap the trackpad to click (tap to click) to be permanently enabled... How do I do this?
