Acer :: Dark Screen; FN Keys Increase Doesn't Help; XP Is Loading
Feb 15, 2009
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.

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'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.

it's been like a year when i bought my aspire 5920g and everything run fine.
It's been about one month that sometimes the computer hangs up at welcome screen or loading the taskbar( the icons are loaded but you cant press them) and the mouse pointer keeps spinning(like it's busy) and nothing happens and I cannot press anything. So i have to restart the pc manually and run a check disk, and every time the problem is solved (this is annoying). But these days the chkdsk command cannot resolve the problem.
Today after welcome screen it hangs on black background and only the cursor can move. I restarted several time and it keeps freezing. So basically i cant start windows.

I just recieved my Aspire 8930. But Im having a problem.
While filling out the information for my operating system, it randomly decided to BSOD on me, loading the dump information then going to a black screen. Now when I turn it off and try to turn it on, the hard drive doesnt click on or even blink the little display, neither does the screen flicker on.

Got a new E5-571P-55TL yesterday and going through the setup process I got all the way to where it says downloading apps. It displayed a message that it was processing or I forget what it said exactly. Then the words went away after about an hour. I remember reading that it said it may do this, may have a blank screen and not to turn it off. I left it on all night and still have just a green screen this morning. I know my wifi is not the fastest and figured that's what it was. Came to work today and left it sitting on the counter, still on.

My friend's macbook (white plastic, 2.0, napa/core2 before santa rosa platform) isn't starting, and I have no idea why. He initially asked me to replace the top and bottom casing. I accepted, and ordered the parts. Around the time they were supposed to come, I took the computer apart completely (required for the repair), but one of the parts was delayed, so the computer sat splayed on my desk for a week. I didn't exactly stack textbooks on it, but it also wasn't covered in anti-static wrap. So, now, I finally got the part and put it back together, and the computer doesn't start. At all. The screen doesn't go grey, the 'sleep' light doesn't turn on, the fan doesn't start - nothing. The magsafe light is green, so the power is going in. It's also worth noting that I have no battery for it, so it's all on A/C.
Does anyone know what's wrong? My two hypothetical solutions are (a) I need a battery, or (b) the logic board is dead due to static.
How likely are each of these scenarios - especially the logic board one? How possible is it that it was static overloaded?

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.

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" ...

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 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.

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?

HP 14 Chromebook product # F0H08UA keyboard doesn't work for the numeric keys 1 through 4 and 7 through 0. Particullary unhandy as I use some of these numbers for my password. Problem started 7/15/14. Worked as expected in the AM but now do not register this PM. The On Screen entry method works but not the keyboard! All other keyboard keys seem to work as expected. No error messages and no recent changes made to this Chromebook 14.

I also tried to use a monitor by hdmi cable but i get a blues creen when i try with the monitor. Also this is happening during a format so i cant even get through safe mode.

My laptop shows me a blank screen after the windows bar loading screen. It did an automatic test on my hard drive to fix files, but when I restarted, it still would keep doing this test. I've tried to use a Windows Vista Upgrade/Recovery, but there is no backup and it keeps giving me an error on all types of restoration. I have just tried the Hard Disk Self Test and it says that there is an error #1 - 04 Fail. From what I've read in the forums, I will likely have to replace the hard drive, but how to recover the files from the old drive and what kind of drive I need to replace.
My product number is: GM010UA#ABL
