Macbook display's back light suddenly turn off?

I using window7 via boot camp (latest) but when I'm using it for a while (an hour) suddenly the display back light is turnoff (like you set brightness to zero). I can see that display is still working fined but the light just down. Pleas help it happen to me several times. My mac is 2008 white model btw.

Hey!
I've recently had a similar problem.
I took it into an Apple Supported Computer Shop near me and they basically said that there was something wrong with the backlight and it turned out that my LCD Panel needed replacing (which has worked out to be quite expensive!)
I would take yours into an Apple store as soon as possible, as my screen got worse the longer I left it.
Hope you can get yours sorted

Welcome to the Apple Support Communities
Your Mac can't find any bootable partition.
1. Insert the Mac OS X DVD that came with the Mac and press C key while your Mac is starting.
2. Select Utilities > Disk Utility, choose Macintosh HD in the sidebar and repair the disk. If it doesn't work, take the Mac to an Apple Store.
Also, open  > Startup Disk, select Macintosh HD and restart. Maybe your Mac has forgotten the startup partition

Hi i'm sorry but what is SMC?
System Management Controller
The System Management Controller (SMC) is responsible for many low-level functions on Intel-based Macs. These functions include:
Responding to presses of the power button
Responding to display lid opening and closing on portable Macs
Battery management
Thermal management
The SMS (Sudden Motion Sensor)
Ambient light sensing
Keyboard backlighting
Status Indicator Light (SIL) management
Battery status indicator lights
Selecting an external (instead of internal) video source for some iMac displays

My MacBook suddenly turned off. And won't turn on

My MacBook suddenly turned off. There was a click sound and then nothing. I have tried to restart it but nothing happens. No sound no lights. It is plugged in and the power cord shows green. I have not damaged it in any way.....

Here is what to do;
1. Unplug everything from your computer.
2. Take off the bottom of your MacBook / Pro / Air. (There are usually 3 screws that are longer than the rest near the vent, remember where they go.)
3. Carefully unplug the battery from the logic board.
4. Wait 10 seconds.
5. Plug the battery back into the logic board.
6. Put the bottom cover back on.
7. Reboot the computer holding the "Option" key.
I posted this originally here. Re: My Mac randomly just turned off and now it wont turn back on, the charger light is faintly flashing green and amber?!?!

MacBook suddenly turns off at 40% of battery charge and trackpad doesn't work

Hello,
I had to replace the battery of my white MacBook (13 inches, mid 2010), because it was swollen, and the capacity was about just 20-30% of its original one. I bought a new one. Specifically, this one. After replacing it, I have those problems:
When I run on battery, the computer suddenly turns off at about 40% of the charge. No warnings. Just turns off.
The trackpad is not working properly. I can move the mouse, but I can not click. The swollen battery was pusing the trackpad, and I guess it's broken now. I don't know if I can replace it.
Coconut battery tells that the maximum charge of the battery is below the design capacity. Not sure if this is a problem, or Coconut battery is just comparing my battery's numbers with the theoretical numbers of a brand new battery. Check a screenshot
The battery drains too fast. From 100% to 65% in about 20 mins. So, at the end, I have less than 1 hour of battery time.
I've tried resetting the SMC, following these instructions. Specifically, pressing (left side)Shift-Control-Option keys and the power button at the same time, releasing all the keys and then pressing power button to turn on the computer. Not worked. I think it was even worse.
Could it be a problem of this specific battery? Or maybe just the MacBook doesn't accept batteries like that one? It's not original.
In the first case, I would return the battery to get my money back. In the second case, I guess I should have bought an original one.
Additional data that may be useful:
Mac OS X 10.8.5 (12F4S)
EFI boot ROM version: MB71.0039.B0E
SMC version: 1.60f6
About EFI boot and SMC versions, those are the last available official updates, obtained from here.
Many thanks in advance.

I'd say it was a faulty battery.

Macbook Pro suddenly turned off when fully charged and won't restart. Charger not working either coincidently

My 2 year old 13" MacbookPro suddenly turned off, presumably when the screen automatically dimmed (or went to sleep?) and now it won't turn back on. It was at 96% charge and now when I use the battery checker on the side, nothing shows up. No lights or anything. The charger doesn't seem to work either even after trying it on different outlets. This has never happened before but it has been harder to wake it from sleep in the last 6 months or so. I would have to push the On/Off button for a sec and the screen would turn back on. Also when I turn it on, the password screen is sometimes off-centered..weird.
I'm using Yosemite, the latest version..not sure what it is and can't check right now...I had to go use a PC to ask this question >_<

My iphone 3gs suddenly turned off and does not want to turn back on.

My iphone 3gs all of sudden turned off and does not want to turn back on.

Charge it with a wall charger for 15 minutes, then hold the HOME and SLEEP buttons until an Apple logo appears, about 10 seconds.

IMac 2008 emc 2211 suddenly turns off and back on, RAM problem?

I have an iMac from 2008 emc 2211.
Two years ago i upgraded my RAM from 2GB to 4GB Crucial memories.
Two weeks ago my imac started to suddenly turn off and back on inmediatly. Recently it stared to happen more often to the point that it can't boot completely and show the desktop
I checked the power source and it was fine.
I opened the computer and pulled out the power supply and it seamed to be fine.
I tried to run the hardware test with the disk that came with the computer and it can't even finish the test because it turns off.
Before it couldn't boot anymore i checked if it was overheathing with smcFanControl and the temperature was always around 44C, so it was fine.
Could this be the crucial RAM that is failing?
thanks in advance.

Ok, i've replaced the RAM and the power supply and the problem persist, so it seams to be the logic board that is failing.
Any ideas?

My Imac will suddenly turn off without warning and then take several hours before it will switch back on again

My Imac will suddenly turn off without warning and then take several hours before it will switch back on again. Can anyone advise?

I like that third tag...
There's really no telling what the problem might be - you may want to try running the Apple Hardware Test (if you can) to see if you've a hardware issue. If you can't even get to the AHT, you've no option but to take the machine into your local Apple Store or an AASP and have them run diagnostics on the machine.
Sorry,
Clinton

IPhone suddenly turn off by itself,won't come back on

My iPhone suddenly turned off when i wanted to unlock it to check my messages(i'm really sure that it has 80%+ battery during that time),here's what i did to get it turn back on,but it still wont on:
1) I plug it to my pc (but my pc says it's an unknown device and it also says that Windows has stopped the device because it has reported problems)
2)i hold on to the home button and the standby button
3) i charged it
I tried all these steps above but it still wont come back on,please help me,i cant live without my phone!

How long has it been off? I have over-heated mine before a few times... (hot car, heating pad...) and it shuts down completely and will NOT come back on until it cools down. I'm not saying this is your problem, but if it did over-heat it will come back on when it cools down.

Sudden turn off and loss of battery

I was working when all of a sudden my MacBook suddenly turned off. I got it to turn back on but it said no battery detected and when I plugged it in there was nothing saying that it was charging. Also now when it is turned on the fan seems noisier than it was before. I've tried different outlets to see if that was the problem but so far nothing. It is still turning on, bur with the problems I mentioned. If anybody knows what is going on it would be greatly appreciated if you could let me know. Thank you!

Try a SMC reset, select the link for a removable battery or a battery you should not remove yourself.
