Apple :: MBPstarting Up - Totally Dark Screen
Jan 8, 2010
just got off the phone with Apple .... seems like I might have a cursed NVIDIA graphics card... had basically kept my MBP ('07 model) in sleep mode when I went to office. When i came back, the white light in the front wasn't pulsing anymore and it was replaced by a bright constant white light - proceeded to open the lid... and the screen was totally dark ... tried a few key combinations in random to get it up and running but to no avail .. then checked a few forums on this issue... seems like lots of ppl have the issue but a lot of them also managed to get the screen back on by resetting the SMC and PRAM (which I proceeded to try) ... unfortunately hasn't worked for me despite multipe resets of the SMC and PRAM. Gave Apple a call and all things point to the graphics card having conked out ... this sucks big time! ...
The worst thing is that after switching on my machine, I can still load software by doing the keyboard shortcut for spotlight and typing the application ... e.g. itunes is working and I'm still managing to play songs through myh machine.. only issue is that the display is totally dark...
Now.. my big issue before I send it across to the service centre is backing up my "Downloads" folder....
how I can go about doing this through terminal ? I think I just might be able to pull it off with the keyboard if I get sufficient and specific help!!!!
basically I'm looking for transfer of all contents from "Downloads" folder to an external hard disk with the name "Active" ...

it happened two times today, the screen went totally black, the fans stop working and the "sleep lights" turned on and off. Soon after the disc drive made the sound that id usually makes when turning the computer on.

I looked at the new MBP 17" today and was dissapointed in the screen quality compared to the 15". It was rather dark and hard to see, even more so when viewing a movie. brightness ws turned all the way up, the apple group had no idea, but agreeded.

My tv tuner INTEX IT-TV 150 FM plays only audio. The screen turns totaly white with no video signal. When calling the supporting staff at INTEX, they told me to install HP Pavilion dv4 video driver. Could this be the solution? If so, where could I find the video driver?

The screen has gone dark/dull on my laptop as though the backlight is faulty. I have plugged the laptop into another screen and this too does not work.

I just bought the HP Pavillion dv5- 1003nr from my brother-in-law. The video screen is too dark and I always have to brighten up by using the fn+f8 keys.
Is there any permanent settings once it is set how I wanted?
I kept brighten up the video screen whenever I use it.

T400 - ONE
I have a problem with two T400 thinkpads. The first T400 was dead when I bought it ( suspected graphics card ) . Well I managed to get this laptop to boot up. The screen was black but I found by chance that if shine a lamp or light on the screen it is working. Now being able to see what I was dooing on the screen faintly. So I updated the bios & that did not fix the problem but I was well happy about finding out this trick. I then added 8Gb kingston ram which works with my other T400 laptops. I installed Win 7 ultimate. The laptop is working fine. No issues just extreamley dark screen almost black "but working" Very strange indeed.
T400 - TWO
Now the second laptop was working fine. But I was swapping the parts with the non working laptop to determine the problem. Now I have two T400 laptops with a dark almost black screen. But over about a month working on them I am making progress. I am determind not to give up on these computers. This is not like fixing or repairing a computer. More like rezerecting a computer. I did not intend to spend so much time on these laptops but I have found a common problem that effects a lot of people. I would love to know why a working laptop when re- assembled gives an almost black screen & still works. Normally I would just buy a new motherboard & bin the defekt one. What I need is some command codes to try to make the screen brighter. Is this planned obsiletion or just a graphic defekt myth. Because after throwing away more supposidly dead motherboards with a graphic defekt than I can count. I am starting to think that if I get the brightness back on my computers I will have sloved a major black screen problem. It is not the graphic processor. I have been playing fifa 14 with a lamp shining on the screen. It played fine, not jumpy ,no colour stripes just very dark.

I have a HP HDX 16 1160-US and a while back, my screen went all of a sudden dark but if I put my face very close to the screen, I could see the desktop icons and start button. I looked around on the internet for possible reasons that this happened. One of the solutions was to change the lcd inverter, therefore I changed it. Once i turned the laptop on with the new lcd inverter, the laptop displayed everything alright, but after I turned it off and on, the screen went dark again. I searched some more on the internet and found another solutuon and that was to change the backlight. To me it made sense to change it because thats where the whole lighting comes from, so I changed that too, but unfortunately that didn't work either. I didn't know what else I should do after this point so I called HP to see if I can give it to them to repair it but they don't have parts anymore for my laptop.

I have a Dell 4310 that I bought used without a hard drive. When I unboxed and initially tested it with another drive it booted into Windows 7, but, did not load because it wasn't the right drive.
The computer sat next to my chair for a few days until I got the new SSD drive that I wanted to install. When I put the drive in and plugged the system in (no battery yet) the battery light on the upper left flashed briefly and the power button came on and stayed that way for about twenty seconds. The screen remained black and the battery light and power button turned off.
This morning my son mentioned that he "might' have spilled a little bit of something on it. I quickly took it apart and carefully dried the pieces and parts on the heating vent and put it back together and the same thing happened.
I have tried the following:
1) Re seat RAM
2) verified video is connected
3) unplugged, held the power button for fifteen seconds and plugged the power cord back in.
What could I be looking at here, a new Motherboard?

Just got the 1920 x 1080 version of the 13" inspiron. The left and right edges (about 5-10% and not top or bottom) of the screen are about half as bright as the rest of screen. Also on closer inspection I've noticed that on the left hand side, the middle part of the rubber edge is squashed in. Is this pretty much normal for these laptops? I'll see if my camera can capture these details.

I've been having problems with my Aspire 5336 laptop. The screen comes on for a few seconds then goes so dark can hardly see it. When its plugged into an external monitor it is ok but as soon as you unplugged it the laptop screen comes on for a few seconds then goes dark. Do you think it is a back light problem.

I received a Latitude E6500 with a WUXGA screen with the dreaded screen brightness problems. This is the same problem discussed here:
E6500 WUXGA -
The bottom corners on mine are very dark. I had been expecting a little, and had been planning on dealing with it like I have with some laptops in the past, but it's kind of outrageous how discolored they are. Screen brightness evenness is very poor as well, with the bottom part of the screen significantly brighter.
My purchase order lists my screen as:
Module,Liquid Crystal Display 15WU+,2CCFL,Samsung Maybach/Avia
How are people getting the exact model number and part number for their displays?
At any rate, it's the bad Samsung kind of screen. A lot of threads including the one I linked to state that there is also an LG/Philips screen that is much better for the same Dell WUXGA screen component.
Has anyone managed to get Dell to change a Samsung screen for an LG/Philips? If so, how did you do so?
My chat rep tells me that they can only replace using whatever was in the order initially.

I'm trying to diagnose this model for a friend: Aspire 3100-1556
The screen is too dark to use. The brightness feature via the function key doesn't help. It does make an instantaneous brightness when pressing it, but it stays dark, doesn't hold more than a split second.
Windows XP IS loading; that much can be seen when looking hard enough. So this isn't an operating system issue. It's there, just can't see it well enough to use.
I have been told elsewhere that it could be the inverter, but as I am new to repairing laptops, I really need more info before asking my friend to spend money on one.

Have Inspiron 3520 with W8 - daughter has infected it via Minecraft update. Original issue was dark screen and beeping, 8 at a time. Put on a external monitor and am going through the long process of digging out the bugs with anti-virus and malware removal programs.
Question is this - how can I stop the infernal beeping? It starts up if I insert the power cord or disconnect/connect the external monitor. Is there any way to silence it?

Am having serious problems with my 4540s, which is about two years old. The bios appears to be totally disfunctional. I cannot get in via Esc, nor by pressing the key which I want, such as the F9 key to select boot device. The machine runs Ubuntu linux and I discovered that I have removed both the HP_TOOLS partition and the Recovery partition. I have now reconstituted the HP_TOOLS partition, but cannot fix the bios.
The machine indicates that the hard disk is faulty, although I can read it apparently without problem on my Mac. However the machine will not hop over the hard disk to try and boot from either the internal CD/DVD drive nor from a usb CD/DVD drive. I have not yet tried a usb stick.
After a period of running, I found I could not, for example, delete emails in T-bird, clicking on an icon would not open the program and I could not close some programs. Occasionally the only way to turn off the machine is by holding down the power button. At the present time it will not start at all, but just cycles through the simplified hardware check, and then sits there with the HP logo on the screen when I exit the test.
Removing each of the 4GB memory chips and/or placing them in an alternative slot has not made any difference.

I have a Envy Spectre 14" with Win 8.0. For the last month or so I have sound disappearing (totally) at random times. Rebooting has generally solved the problem...but that can be a pain if I'm in the middle of a lot of projects. It was working this morn....closed the lid...opened it 30 min later and NO sound.

I have an Inspiron 6000 from a colleague. His report was "my daughter spilled (coffee?) and it broke".
Turning on, I see the LCD has the image but the backlight is not working (a few times it flickered on for a second). External video works fine.
I opened the thing, did not see obvious spillage signs.
Bought an inverter from eBay, replacing it did not fix the problem. If anything, the "sometimes flicker on for a second" stopped to show up. Had the eBay dealer replace the inverter as DOA, the second one didn't work either.
I guess it's not the inverter
What's the next step? Should I be going after a motherboard (following the spillage lead) or a screen? Or try the backlight specifically?
Is there a way to measure the inverter output and see whether it's alive? "Yes" would point at the backlight. "No" would point at electronics, in this case the motherboard.

I've only had my HP Elitebook 8530w for a few months now and is my first laptop. I love just about everything about it. However: Recently I have had problems with the screen going out on me every so often. It just randomly goes very dark, to the point where it looks like its off, but I can still see VERY slightly whatever I was working on before. Has anyone experienced this and possibly knows what could be going on? (it just did it again. 3 times in a one hour sitting)
Whatever anyone can suggest would be awesome. I'm not to savvy about laptop hardware and such, so i'm a little ignorant when it comes to troubleshooting this issue,
I forgot to mention. Here's some specs.
Core2 Duo T9550
15.4" WUXGA
GFX nVid FX770 512
RAM 4GB DDR2 2DM
HDD 250G at 7200rpm
standard 8 cell battery

I just purchased a brand new HP Pavilion dv6-6130tx from Hong Kong four days ago and I was very content with it. The webcam quality was decent until yesterday when I wanted to use the webcam with pre-installed 'cyberlink youcam'. The capture was dark, even when I checked the 'auto lighting' feature. I have been searching this forum and the driver and support HP website for a fix, but there is no webcam driver I can use to re-install. I have tried updating the webcam driver through 'Device manager'. I even uninstalled 'Cyberlink Youcam' and installed 'HP Mediasmart webcam'.
Everything is dark and not even my face is recognizable, it only shows intense light. I am not sure whether it is a software failure or a hardware failure, but I can't seem to find the root of the problem.

1) Disabling Adaptive Brightness
2) Turning the brightness settings to max
3) Trying the brightness settings in the Intel Graphics configurator
The laptop is much darker than any other laptop i've ever had. I have a Yoga 2 and a Macbook Retina 13 that are both much brighter. Its very hard to see ....
