does anyone notice that sometimes the screen light will dim over time? (new alum unibody macbook)
is it because sometimes i use a lamp really close to the laptop vs other times using a far away light source? does the brightness change automatically?
i sometimes increase the light to full..and then maybe 2 days later...i find it is 2 notches lower..without me doing anything...
I have a problem with my screen - when there is something black on, I can see a faint mark of a lighter colour. I have tried to take a picture, please excuse the poor quality. There is nothing visible when the screen is off, even under close examination. Is it less visible when lighter things are on the screen, and invisible when the screen is white.
No drops or liquid spills. Will this go away on it's own? Any fixes?
Is it just me or the macbook air has a problem with backlight? it's very very bright compare to my mbp 13.3 but it seems like the left part of the screen receive a lot more light than the bottom right of the screen. I notice that on the mbp pro but its worse on the mba. I have a rev2 1.86 with a 9400. In this review (in spanish) they check the brightness levels on the screen, and there is a difference between center and bottom right corner (340cd/m2 vs 215cd/m2)

When shutting down, we get a familiar light blue screen before the computer turns off. I'm getting this flashing at me while operating my MBP. It seems to happen twice, every so often. The screen will turn blue and become empty simultaneously for about a half second - then the screen I'm expecting to see comes back for about half a second - and then the light blue screen comes back again for about a half a second, and then everything goes back to normal.What the heck is this?
I must say, I'm having a little bit of a difficult time with my switch to Apple from Microsoft last November. I've already had to replace the logic board, it appears as if my network card is no longer working (I can only connect via WiFi) - and now I'm having this odd light-blue screen flashing... My video card?
I just bought a new unibody Macbook (YAY), but when i play full screen movies, at the bottom of the screen you can see the light shooting up. Is that worthy of a replacement? Or is that normal on a LED screen? I just purchased it yesterday, so I can just go exchange it if its neccessary.
View 2 Replies View RelatedI just bought a Black, 2007 MacBook for $500 from eBay. In my excitement, I had forgotten to ask the seller of the cosmetic condition, who had negelected to mention it, and now that I have it, I notice some dark spots behind the screen.
I say behind because they appear behind the pixels; if you roll rext over it it is clear that they are not dead pixels, and the spots are under them.
The spots look sort of like somebody painted the back of the screen in Photoshop's dissolve mode - little light grey spots around a darker grey center with dusty dots surrounding it.
If you look at it at the right angle, you can also see white spots (The grey spots will also turn white at this angle)
My question is, can it be fixed, and about how much will it cost?
Upon start up I hear optical drive checked, then get a start up chime but the screen does not light up. I have shut down by holding down power button for 10 seconds also pulled battery and A/C power.

I just fired up my almost new Macbook Pro a few minutes ago and the screen is totally dark. Not dimmed, nothing at all. The keyboard lights up.
View 2 Replies View RelatedI woke up this morning and my Macbook Pro won't turn on. The sleep mode light is just constantly on but there is nothing on the screen. I've tried shutting down and booting back up. Removing the battery and putting it back on and rebooting. I've tried rebooting without the battery and plugged into the power adapter. I've reset the PRAM. I've took the battery out and held down the power button for 5 seconds. Nothing seems to work.
Also, the last week the battery said "replace soon" and then the other day it said "replace now". I've checked the battery level and it seems to be fine. And wouldn't it just start up from the power cord? I would love for it to just be a battery issue. But it not starting up with the power cord and the sleep mode light being constantly on makes me thing otherwise.
I've got a nasty issue with my 13-mo. old MacBook.
I'm pretty sure it's a dead logic board and possibly a dead hard drive, which I really, really, really hope not as I don't have backups of everything on the drive. I just upgraded to Leopard this past week and did a clean install so not all of my stuff is setup yet.
Power adapter and battery are inserted. All 3rd party peripherals and RAM have been removed.
MacBook does not chime at boot. The screen flickers, but stays black. If I hold down the power button then try to let it boot the light on the front right flashes constantly (like when it's sleeping but a faster pace), like a turn signal on a car. I can hear the cd-rom drive whining but everything else is dead silent.
I've done everything here with the exception of calling Apple.[URL]
I've also tried FW Target Disk Mode, but the MacBook drive does not show up.
I've done everything I can think of and I'm out of ideas at this point.
Additionally, there's a cd-rom (Tiger Restore CD) stuck in the drive. Holding down the mouse button during restart does not eject this CD. Where is the force eject button (I see no pinhole)?
I have business documents, emails, etc. that I HAVE TO get off this hard drive. How can I do it? I don't have a 2.5" drive enclosure but if that will solve the situation I will pick one up asap.
I was using my MacBook this evening and navigated to a webpage that wouldn't load (perhaps due to excessive load) when my screen turned off and refused to turn back on. The white "sleep" light remained constant. I shut the screen and the light started to blink after the optical drive made it's noise and then I opened the screen again. The display turned on for a few seconds turning back off and the light on the front reverted to it's constant state.
I repeated pressing keys, the mouse and closing and opening the screen a few times before holding the power button down and forcing it to shut down. It's working fine now. I am wondering what caused this sudden behaviour though and how to best stop it from happening again, if I was working on something that needed to be saved, I'd be buggered. Perhaps it's an issue Apple needs to service, but how do I reproduce the effect then?
At the time I had a few applications open:
Mail
Safari
Mercury Messenger
iTunes (not playing)
Last.fm helper app (but no songs were currently playing)
I was thinking it could possibly be related to the Last.fm app, but why would it turn my screen off and then cause it to continue to not respond/turn off? Should I be looking in the Console for a log before shutting down tonight, would that reveal something?
Does the new MBA still have the ambient light sensor that adjust the screen brightness to environment?(like the older MBA and the current MBP)
View 1 Replies View RelatedMy 2010 13" Pro seems to have some blue/magenta light leaking from the bottom of the screen. This is only visible with the brightness turned up and against a black background (i.e. when watching a letterbox movie). It's quite different from the "typical" white light leak that I've witnessed on other lcds. Would this be "normal"?
Also - and this may seem like nit-picking - but my caps lock key feels a bit flimsier than the rest of the keys. Again - is this "normal"?
Can a few folks comment on how long it takes for your screen to light up and to hear the optical drive make noise from the time you push the "On" button? I've seen a few videos and some comments here as well that it is nearly instantaneous and then the MBP goes into its boot cycle. I have an X25 SSD which boots me into my desktop in about 19 seconds from the button push BUT there is about a 5-6 second delay from the time I push the "On" button to any activity. Any ideas how to fix this (if it is, indeed, a problem)? Again, some other folks report instant activity.
View 2 Replies View RelatedThis morning, I synced my iPod with my MacBook and upon completion and permission to disconnect the device, I pulled out the USB cord. At that point the computer instantly turned itself off, and when I hit the power button, I could hear the system trying to start up, but the screen remained black and the sleep light glowed continuously. I unplugged the charger, took out the battery and put it back in, and tried all the troubleshooting tips under the Apple Support guide with no success. I also discovered that when I closed the laptop while it was "on," it would seem to boot up a little more before returning to the black screen. I left it alone for a few hours, and when I tried again to turn it on, it booted up normally and as I was searching for updates, it shut down again as it had earlier.
Does anyone have anything for me to try? I don't want to have to take it into a shop because I can just barely afford to, but I need this computer! Any suggestions would be greatly appreciated :-)
My friend just got his CTO MBP15 i7 anti-glare hi-res and we compared it to my old Core Duo MBP15 screen. Do you think there is light leak in the new machine? It reminds me the memory of "Apple Lottery". Now I am nervous since I am going to order one.
Left: 2010 MBP15 i7 hi-res anti-glare 9CB7
Right: 2006 MBP15 Core Duo anti-glare 9C56
The new one is brighter so I adjust the brightness for fair comparison. Should I tell my friend to replace it? I wonder if other ones have the same issue.
When I am in a quiet room, I notice a light humming coming from my macbook pro and also a light vibration on the right side. Is this just the hd spinning or something to be concerned about? it is 2 weeks old.

Got my macbook here. Bought it 1.5 years ago. Out of warranty. Running on 10.5.8. When I printscreen it, the white strip does not appear. Its present even when I'm using my mac. And additionally, It's only visible when the background isn't white or black. Also, its been happening on and off. It normally goes away if I've been carrying my macbook in my backpack and then open it up again (leads me to think maybe it is sensitive and may have been bonked on something while I was carrying it in my bag). However, this time, it hasn't gone away simply by rebooting it.
View 2 Replies View RelatedMy faithful and trusted Intel Mac mini 1.83 C2D that I bought new in December 2007 suddenly died during a major 10.6.3 update install. It almost completed the update and the screen went black and the light went off instantly. The power button doesn't respond at all. I had major work projects going on Sunday night when I took a break, quit all applications and did the software update and it died. I took it to the Apple Store Monday morning thinking it was the power supply. I was informed that the logic board is dead and my HD has to be wiped and OS X reinstalled. The repair would cost well over $300 and have a 90 day warranty with the same logic board installed that could fail again. Ironically enough, I had been thinking about buying another new Mac mini and a new Mac mini Server for work. That's not going to happen now. I left the Apple store with my new $600 paper weight for my desk. What would you do? This was a sad day in my faith in Apple products. Apple Mac mini lemon?
