Apple :: 13" MBP Screen 9CC2 - Backlight Was Not Strong Enough To Overpower The Reflections
Jul 23, 2009
Got my MBP yesterday. It came with a 9CC2 screen, which is supposedly AUOptronics.
Contrast is very high, I reckon above 800:1. Colors and viewing angles are very good too. It has one problem: brightness.
I used it outside with sunlight but the backlight was not strong enough to overpower the reflections. My MBA was much brighter, and also the 9C89 screen on my first uMB was brighter.
When I'm working inside the house during the day I'm usually on 1 or 2 stripes from the max.
It's a not a huge problem for me because I did not really plan on keeping it for long but if I buy again I'll probably try to get another screen. Expecially the MB April 2009 screens interest me. I've never seen them in real life though.
Here are some pics of it next to an Asus 1101HA which was measured at 129 nits max by Notebookjournal.
The first three are on full brightness, than half brightness. Keep in mind that photographs can not really give an accurate impression of brightness levels.

1.I'm really really picky about keyboards, is it good? i want to buy one tomorrow and im so worried about it, i have Vaio CS16 now and i want a keyboard with same quality, because there's no way to replace apple laptop keyboards in my country, so i want to be sure it works fine for at least 2 years.
2.Is Macbook 13 White keyboard better or Unibody?

Now almost always when I trying to resume from standby on battery MBP isn't turning on backlight - I can even see MAC OS working normally but screen is off.

In the past, I used to have an hp pavalion laptop. I usually kept the screen at a little past half brightness and in 3 years, the screen no longer even turns on which means the backlight is dead. The same thing is true for my mother's 17 inch lcd monitor. Now I realize that this may just be bad luck, but I don't want to risk anything with my new macbook.
What's a "safe" level to leave the brightness at? And is the LED long lasting? Is it expensive to replace? I hate dim screens but I don't want this screen to die that fast, I want to make this last AT LEAST 8 years.

I had some M6400s at home (2 E2E RGB, a non E2E and a CCFL one) and took a look under the bezel/E2E cover. So if someone gets annoyed about the reflections of the E2E-cover you can exchange it with the normal bezel (you need some tricks to order it from Dell as a spare part)

I'm seriously thinking of replacing my Go 7900 GS GPU with a Go 7900 GTX. (within some time because I don't have enough money right now (I'm only 14).
Now is my question, is my adapter going to be strong enough for the Go 7900 GTX? From other hardware, I have a T7400 (2,16 Ghz Core 2 duo) a seagate 7200.3 (Seagate says: "The Seagate® Momentus® 7200.3 laptop hard drive delivers industry-leading 7200-RPM performance while offering the industry’s lowest power consumption levels.") I have 4 GIG hyperx RAM.
And another question: where can I buy a Go 7900 GTX, I found some on EBay, but I don't like that way of buying things. Is there a direct way to buy one from Dell? I searched on their sitre but didn't find any link for spare part GPU's.

T5800 (2.0 GHz), 4 GB RAM, 320 GB 5400 RPM HD, WUXGA display, Blu-Ray Burner, 8400 GS video card, and all the other standard stuff.
I picked it up primarily because I had some minor issues with the HP HDX16T I bought about a month ago. I loved it, but it was really about 2-3 pounds too heavy (with 12 cell battery) and the battery didn't last very long at all. It was similarly equipped, in that it had both the HD display (16" 1920x1080) and Blu-Ray drive (only a reader).
Unfortunately the battery in the XPS really didn't give me quite the performance time boost that I hoped it would, and the display looks like absolute crap compared to the HP (no offense to anyone here).
I had heard all this business about the "grainy" displays from Samsung, but I hoped either I wouldn't be afflicted or just wouldn't notice. Well, turns out I do notice...a lot.
What's worse is that it's inferior to the HP display in every other way too - color reproduction looks way off (everything is WAY too blue out of the box), its less forgiving of viewing angle, and overall the colors are just really muted in comparison.
Is it possible that I just got a bad one? Most of the posts on here indicate the only way to "fix" this issue is to replace your screen, which seems a bit daunting to be honest .....

I got my E6400 last week and I found that everything all right except the color of LED screen, it's awful.
The color of the screen is pale, i had tried to calibrated the graphic settings but it doesn't improve too much.
Also, i saw some posts here said that the LG screen is better than the Samsung screen, but I can't agree with that because my screen is LG.
Is it normal for LED backlight screen that the color is more pale than the CCFL backlight screen or just the screen of mine had some problems?

new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...

Unfortunetely I received a unit with uneven backlighting on the screen (9C84), with a few column of light bleed towards the center that goes from the bottom of the screen and reaching up past mid screen. It is not visible with normal use, but on dark solid backgrounds, or when watching movies with dark scenes, it is definetely there.
Do all unibody MBP have this backlight bleed problem? Are there ones out there with perfectly even backlighting or atleast with very very minimal bleed? Just trying to find the statistics of this problem. I will be going to the Apple store this weekend to check out the MBPs they have on display to see how widespread is the problem.
If this is indeed a problem for all unibody MBPs, then I wont even bother and just accept what I have on a premium product.

First off before I get into the problem I want to say that I am an experienced computer technician having worked on hundreds of laptops in the past. So I'm very familiar with the problems and solutions for them.
I just want that disclaimer to be up front that I'm not a rookie seeking laymans terms or solutions.
Anyway, that aside. A customer dropped off an Inspiron 5160 last week. The system wouldn't half power on he said so after testing, I determined that the AC jack was 'broken'. Sure enough after disassembling the computer I could see on the bottom of the motherboard where the AC adapter had been knocked loose.
I replaced the motherboard and immediately noticed that the screen would display the BIOS Dell logo for about 5 seconds, and then cut off.
With a flash light I could see the data images on the screen, just no CCFL light from the bulb to brighten the screen.

Problem with my 2 week old sony vgn-z540 laptop.
Heres the problem:
When I try to use the brightness level in between LOW and HIGH, my LCD backlight would go off, and the screen would be dark and almost not visible at all. There are also vertical bars at random spots, stretching from the top of the screen to the bottom of the screen. I can only use it with either LOW setting or HIGH setting, nothing in between.
This problem just started on its own. I have not installed anything such as drivers or programs. No updates(was updated after the problem occured to try to fix it).
I love this laptop to death and has been the best laptop in the past 15 years. I would hate to see it go so I need this fixed.
I will update later with pictures when it gets dark here b/c the pictures now are not showing up with the bars.

my laptop screen backlight goes off, when I rest my hand on the left side of the touchpad. The darkening of the screen can be also reproduced when a small pressure is applied on the case just above the ethernet port or above the headphones port.
When the screen goes dark, I can see that everything is running normal, if I shine on it with a lamp or strong light. The resulting effect seems to be the same as if I would have lowered the brightness to minimum.
Â
When I don't press the area described above, the screen is just fine. I am sure this problem is not software or OS related. I googled it a lot and my guess is lose connection on the inverter?
Â
One last thing - idk if related - sometimes, when I boot up the laptop, the backlight is turned off and I have to adjust it by pressing F3.

i assumed the screen was knackered, but i installed a game a few weeks ago and it brought the display back to life, only for it to look crap again when i restarted. this also happened when i did a clean install of vista, only for the display to go bad when the updates installed.
i have tried many times, but have been unable to replicate this...............

Alright Well I bought a new inverter plugged it in and it still is doing the same thing. Only when i jiggle the wires the light goes on and i see the screen but not for long. I check for loose conncections but can't find any. The external display is fine. I'm wondering if it could be the actual bulb.

My current problem is that when switching from the mobile power-saving GPU I lose the backlight on my screen when the high performance GPU kicks in. The HDMI output is displaying video when in High Performance, but the screen of the laptop will only show a picture with no backlight, and can only be seen by shining a light on the screen.Â
Just started happening the last few days, I've tried a system restore (didn't allow it), tried uninstalling all of the AMD drivers and software then reinstalling with their updated drivers, as well as the same process but with the HP drivers that came with the laptop, still the same result.Is it possible for the high performance GPU to be failing some how or is this a software issue?

On my old XPS, when the screen turned off, the keyboard backlight would turn off with it automatically. My new Inspiron 17 does not do this, and I can't find anything that seems to control the behavior. Is there a way to do this?
Alternately, is there a software solution to control the keyboard backlight?

After using my new Vaio Z for a few hours i noticed a slightly greenish hue at the bottom of the screen(1600x900). It's mostly visible with white or very light background.
There are a few of those spots and i think it originates from uneven LED backlight. It's not instantly obvious, but after i've noticed it I find it somewhat distracting.

The MBP I bought in Aug '07 2.4 GHz model seems to be having some screen issues... in particular ... pixel issues on the far left side of my screen... I'm attaching a pdf shot of the areas in question that i took with my camera ... there are quite a few patches of pixels that are remaining a shade of white and are not responding to any colour change in desktop wallpaper/ movies/ anything...
I'm terribly dissappointed with this... i've taken pains to ensure that the MBP is always padded when i take it out (and i can count the number of times i've taken it outside home with fingers on one hand) .... so... i'm sure i haven't bumped it anywhere...
I have the apple protection plan...
any advice on what my options might be at this point? would apple look into screen replacement options? I'm in India and there aren't any official apple stores out here either:| (the closest thing out here to an apple store is a premium reseller) ...
on a totally separate note .. my battery seems to be performing excruciatingly badly as well.. health is at 84% after 64 cycles ... and that's after i've done the battery calibration tests ......

I'm having a problem with the back light of my laptop. I have a Studio 15 that I bought around 1.5 years ago.
I don't know why the back light randomly stops working. When it happens I turn off the screen and turn it on again and it works fine. Any clues on what is happening?

What are the symptoms when your LCD backlight craps out? The screen on my i9300 is black but I can see images, although it is very very dark, like the lcd is working but it's not lighting up. Also when the lcd crapped out, there was a burning smell.
If I do need a new LCD, would it be worth it to replace? My laptop runs great and I'd love to keep using it.
