The brightness is turned all the way off on my MacBook pro and the only way to turn it back up is through system preferences. But I cant see it and everytime I push the brightness control keys it makes a beeping noise. And won't do work.

I'm having a custom keyboard connected to my mac, but I want to change the brightness keys to my preferences. I can't seem to find them though.where I have to change it?
Info:
MacBook Pro, Mac OS X (10.7.3)
When I push the brightness key on the keyboard, the appropriate image comes up on screen and goes to full brightness, but the actual brightness of the screen doesn't change and the lack of change is reflected correctly on the brightness slider in System Preferences.
View 2 Replies View Relatedwhen i was on my laptop and i forgot to put it on charge so it went flat while i was watching a movie (not on the internet). I couldn't be bothered charging it so i just put it down and went to sleep. The next morning i turned it on and tried opening safari and it went extremely slow, i got the beach ball and when i clicked the apple on top left to try to force quit, after 2 seconds of clicking that froze. When i tried to force quit it from my dock i would click force quit and then my dock would freeze. At this point my mac was just about completely frozen. The brightness didn't change, sound nothing but only the mouse could move. I reset and the exact same thing happened. Google Chrome works so i am using this and i get no freezing problems. It is just when i use Safari.

The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.

I went to Best Buy yesterday and they just got the new imacs in and had on display side by side. The 21.5 display was not as bright and vibrant as the 27 display. The apple and best buy guys could not tell me why the difference. The settings were checked and found to be the same for both machines. I was going to get the 21.5 but now not so sure. I definitely like the brighter 27 better. Is this normal? Why is the 27 brighter? Has anyone else noticed the difference?

View 2 Replies View RelatedMy Macbook Air is doing something pretty strange..
This is as far as my brightness will go up. This is using the keyboard brightness thing on F1 and F2. When I go into the system preferences, I can drag the brightness to the top, but as soon as I release the mouse, it automatically flicks back to where it was before without getting any brighter.
Does anyone have any ideas as to the cause?

When I use this, whether I use the word, web surfing etc then adjust the brightness of the screen itself from strong to weak and back, all the time. This happens both when connected power and do not. And no, it's not that it goes into power saving mode, this occurs during use.

I have a 2012 macbook pro and needed to change the brightness of my monitor for my eyes, the problem is I find it hard to see the tab bar now because it is too dark. I looked on these forums and found how to change the brightness of the tab bar without compromising any of the other parts of the screen, but it is not for my particular year or model " [URL]

When I turn my brightness all the way down, there's still a barely (but clear, still) lit circle at the centre of my screen. I have a 13'' mbp. I can even see my cursor and move it around. This spot, at very low screen brightness, appears kind of yellowish. When I turn the brightness up, it is not noticeable. The circle part has roughly a two inch diameter.
I've had the mbp for about a month, and just noticed this now. I do turn my brightness down quite a bit, but its usually in a well lit classroom and thus its possible I just did not notice this circle that is still barely lit until now.
UPDATE*: I have just discovered that covering the lit apple logo on the screen's exterior (directly opposite the lit circle i suppose) causing the circle to gradually disappear. THe laptop is sitting behind a window (ie light can shine on that apple logo)...what's up with this?
I just got a new 15" MBP and it keeps changing the screen brightness by a couple notches either way on it's own. Anyone have/heard of this problem?

View 24 Replies View RelatedI originally purchased a SR MBP a couple weeks ago and come to find out, the LCD was bad and Apple declared it DOA. I went to the Apple store and swapped it out for a new 2.4GHz Penryn MBP. I am running Vista via bootcamp and am noticing a high pitched whine coming from the top left hand side of the keyboard, near the LCD. Puzzled as to the cause, I started playing with some controls to see if anything made a difference and noticed that when I dim the LCD to the min, it almost goes away. When I turn off the LCD it does in fact go away and when I increase it to maximum brightness it also vanishes. The noise seems to be the loudest when the LCD brightness is set in the middle. This problem only occurs in Vista, not OSX. I thoroughly toyed with the brightness in OSX and listed carefully, but like I said, not noise is present.
Should I be concerned and call Apple, or just ride it out? It does bother me a bit considering I use Vista for Office 2007 tasks. However, since the problem only occurs in Vista and not OSX, it this indicative of a software issue, or do you guys think it is hardware related? cmm26red
I found the setting under Displays to automatically adjust brightness, but is there a way to set this different for Battery or Power Adapter? I would like to keep this option on for using the Battery, but would like the display at a constant level when using the Power Adapter.
View 3 Replies View RelatedI recently purchased a unibody macbook pro 2.8Ghz (awesome machine by the way) and was wondering whether would the LED screen get dimmer over time like the previous non unibody models?
When I had my powerbook and non unibody macbook pro, I had a habit of keeping the brightness at full and realize after a while it starts to get dimmer and dimmer. A good fren alerted me to try and keep the brightness at 50% to conserve battery life was wondering do u any of u notice the same dimming occuring on ur UMBP?
Recently, after about 5 minutes of use (not sitting idle), my MacBook's screen will go very dim. I hit the buttons on the keyboard to take the brightness all the way up, but it doesn't get much brighter and there's only one thing that I can do to make the screen go brighter: I go into System Preferences and click Display. The second I click that, the brightness returns without me doing anything in the Display section, so after Display comes up, I just close it out and the screen brightness is fine for a while. It seems to do this after the lid has been closed for a while and then starts dimming again after opening the lid and using it for about 5 minutes. Is there a way to fix the auto-dim mode without disabling it? MacBook (white) is running Leopard 10.5.8 with all the latest updates.
View 2 Replies View RelatedA few weeks ago the display on my 2008 Macbook started going black randomly. I wouldn't call it a flicker, because when it goes black, it does not come back on unless I turn the brightness all the way down, and then back on again.
Sometimes it will go black, I turn the brightness all the way down, then back on again, and it will stay lit for a few minutes. Other times, the screen flashes when I turn the brightness up to 1 but then goes to black immediately. There are times where it won't stay on for more than a split second for almost half an hour, and I can't do anything but keep trying to turn it on in the meantime. Eventually it will start to work for either a few minutes, or half an hour, or longer, but if I turn it up too bright, it goes to black again. I keep it at 2/16 brightness once it starts working. If I'm feeling lucky I'll go up to 4/16.
So after doing some research I decided to try and replace the inverter. I just did this successfully, and after a few minutes the problem returned. So now I'm at a crossroads. I can take it apart again and replace one of the inverter cables, but I'm not too hopeful about that. I'm out of warranty and will not pay hundreds of dollars for Apple to repair it. My long term plan-B is to buy an LCD monitor and wireless keyboard to use it in clamshell mode.
So my question is if anyone has any other ideas about what may be wrong, and what I can do to fix it. The display itself appears to be fine. My dad thinks it may be a motherboard issue. Any thoughts?

Just wanted to ask if there is a brightness/resolution/clarity difference between these two model?
I dropped my laptop on a tile floor and the bottom hit it flat. my computer works fine besides the fact that my computer screen's brightness is as if my brightness level was all the way down.
View 4 Replies View RelatedWonder it's just me or hardware/software issue. If I set brightness at 50% with power adaptor on, and sleep, unplug, open lid or do vice versa, the next time when the MBP wake up, the brightness either goes to lowest setting or highest, very annoying. Sometimes I see keyboard light did the same thing but not as frequent as screen backlit.
