Dell :: Xps M1710 Screen...backlight, Really Lights Up.
May 5, 2010
Is this the backlight? i hot glued the connector and wires in the socket into the inverter....?
I have replaced the inverter AND the flex cable (yes, the part numbers are right)
I have to shake or pressure point the left-middle of the screen for it to stop otherwise it stays unreadable...
when i hook it up to an external monitor...

I replaced my Inspiron 9400 motherboard with M1710 XPS motherboard.The palmrest,lcd cover,hinge cover,front speakers,is M1710 parts.The only parts not XPS M1710 is the standard non led cpu and video fans which I borrowed from my Inspiron 9400.
The cpu and the video fan is borrowed from my I9400.Non LED.Could this be the cause?
My M1710 backcover,M1710 touchpad,and the front speakers do not light on.Eevn when the system is booting up in bios.
I already checked all connections and have the above all above
enabled in bios.

anyone at all been able to light up the cover lights (just one of the colors even) for those who have done the 9400/E1705 to M1710 mods? I would really like to know how this can be done if there are some theories out there. Please refrain from saying how much you hate the lights or asking why I would care to do this :
Some methods I thought about trying:
USB port: 5V ok, will that work with the cover LEDs?
Fan port: I have heard this one might not work but can anyone confirm?
(I am talking about cutting off the connector that would originally go into the M1710 mobo and trying various things with the wires that happen to be color coded, 2 for each color of LED apparently.)

I know it's kinda dumb but it's annoyingly bright when I've got the computer on at night and it's busy converting video or doing other work. It's also less power used.
It can't be done through software but has anyone physically unplugged them? I've not opened up the case yet so I don't know how practical that would be, thought I'd ask around first.

I recently have had a problem with my Dell XPS M1530. The laptop crashed from what I presume was it overheating. When I switch it back on the screen lights up white with no display. I am able to use the laptop through an external display (pressing FN F8) however the quality is very poor, this is surprising as I used to use an external display frequently at a high quality and I am now unable to change the screen resolution in the display settings. I have also noticed that I can no longed put the laptop into 'sleep' mode. How the two errors could be related but both happened after the same crash.
I have tried to recconect the video cable but unfortunately it didn't work.
Any simple fix to this problem or if the GPU or screen needs to be replaced?

I currently have a dell xps 17 laptop. It will not switch on properly.
When I power it on, the lights flash on as normal, and some of the fans appear to start (although the side fan does not appear to work). The cd drive will open when I press the button, and the touch buttons light up on contact as normal.
However, the screen does not switch on at all. The laptop will stay on but nothing will happen. The side fan does not appear to be working either (i cant hear it, and that area gets VERY hot when plugged in).
I am currently on holiday and do not have an hdmi cable to test it on an external display (though I could maybe buy one).
I have tried fully charging and depleting the battery, I have tried removing and reinserting the coin cell battery and the memory.

My Dell Inspiron 14 1440 froze and i decided to manually turn it on and back on. I pushed, and held the power button until it turned off. Once it turned off i decided to take the battery out (for no apparent reason). So i took it out and put it back it (i didn't really touch anything). Once i put it back in i tried turning it on by pressing the power button, but it wouldn't turn on. The screen is black, there are no blue lights that are on. (These lights are on when you turn the laptop on).I tried the taking out the battery and hold power button for 30-60secs trick, but no luck. I also have taken out my laptop's ram and re-inserted it (same with my hard drive). Oh and my battery is fully charged. I tried searching the net for solutions but no one really has the same problem as me. Most of the other people with problems said they could hear the fan, but with mine there is noting. No sound. No lights. No working laptop just one really expensive door stop.

I have had my Dell studio xps 1640 for around 2 years now, apart from the common overheating problems has been working fine.
Last night i powered down as usual after watching some live stream football, this morning went to start up again and the keyboard lights up & can hear the fan running but getting completely blank, black screen. It seems windows isn't loading up either as if i push the power button again it shuts down instantly.
I have always kept the inside clean and free of dust and really need to know what may need repairing. Could it be a Graphic or video card or Motherboard problem.
I have also tried the usual checks of memory but have not tried to get display via vgi or hdmi in to another monitor.

Suddenly one morning when switching on the laptop it just was a black screen nothing else, I have already had the graphics card replaced so checked the ram by trying different combinations etc but still nothing.
I did the FN + Power test and it does its thing but then it beeps loudly 3 times while flashing caps lock, scroll lock & num lock together at the same time,,,,then it does a random tune and flashes more. I have attached a video to show it exactly.

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) ...

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.

I recently suffered a complete failure of my xps m1530 which was purchased new from Dell in 2008. The blue lights would blink then go out and no apparent boot sequence or illumination on the screen.
The suggestions led to a diagnostic determination that the problem was likely a faulty Nvidia chip which, of course, is integrated into the motherboard. The solution was either to replace the MB ($165) or to watch a Youtube video regarding a method whereby a small torch or even a hair dryer might be used to reestablish the pin connections. I watched the video, used the torch as suggested, and my computer now works as it should.

Whenever I am charging my laptop and using it, the screen lights up to the highest brightness (I keep it pretty low most of the time). This often leads to my mouse freezing, and then I have to shut off my laptop completely. I'm using a HP 2000 Notebook PC, with Windows 8.1 64-bit.

My Dell 7720 has uneven screen backlight on the edges, is it normal? Do all the 7720 dell laptops has the same issue with the screens, or it is only my problem?
Here is the video where I make screen darker and brighten: [URL] ......

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?

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.
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?
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...............

I have a compaq presario CQ61-420US with similar problems below, except I have a black screen, fan turns blinking lights are the same (num lock and cap lock) but they are flashing continuously every second or 2. I have tried the hard reset with the ram fix, connecting an external monitor, changing the battery, and the power adapter to no avail. I also used compressed air on the vents just in case was stuffed with dust since it will overheat and may cause problems, but nothing.
One option I can think of is purchasing a new MotherBoard, but I'm trying anything else before that.

Got windows 7 on my g555, with truecrypt on the drive, if it matters. Last night, closed down the cover of my laptop before i fell asleep, like always, today it doesn't respond at all when I opened it back up. Forced it to shut down, and haven't seen anything but a black screen since.
The power light comes on, the fan comes on, and that's about it. Can't get to the bios, can't do ANYTHING. Tried unplugging it for a while, pressing power 10 times, holding power down for a minute, ran the battery entirely dry THEN discharged the caps, ...I've read many solutions where its the built up static charge that's the problem, but not here. I've tried all versions of the solution I could find, all very similar, but none worked. I took out my RAM and put it back in, and same for the hard drive. No dice.
The only lights I get at all are the power light, and the battery charging light next to it. Can't get the CAPS LOCK, num lock, any of that to do anything. Cannot boot by CD/DVD as I cannot change the bios, and can't get any response from any keys or key combos that I can think of (including the one-touch restore).

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.
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?

I have an M1710 (3.5 years old), and have recently installed Windows 7.
System stats:
2GB RAM
XPS 512MB NVIDIA GeForce Go 7900 GTX
XPS M1710 Duo Processor T2600 (2.16 GHz, 2 MB L2 cache, 667 MHz FSB)
However, since yesterday, when I press the power on button I just get a strange grey screen. I can't get past this. I left it overnight and in the morning I get the same thing. It is a mainly grey/white screen and if I leave it some more bits of grey appear on it in a strange way. I'm not really sure what to do. I've never openened my laptop up to remove dust but have blown through the fans a few times so I imagine that it is very dusty inside.

My M1710 is 2.5 yrs old now but is still working fine for me. The only problem is is my LCD screen has some problem and i see a lot of dots on it especially when the background is dark like in a horror movie.
But still it is usuable. I showed it to my local engineer and also contacted dell and they asked me to get a new warranty and they will replace the lcd.
But I don't really want to spend that much and I have a spare LCD monitor which i am currently using with a VGA cable. I can do tasks as long as it doesn't require me to use the keyboard as the screen is almost closed.
