Dell :: M6400 Random Black Screen Experience Log
Sep 6, 2009
i am aware that there is a lengthy thread on the owners of the m6400 and even a shorter thread on the crashes of the m6400 while gaming, namely wow and others...
i've recently purchased an m6400 and i too have become a victim of this issue.
until recently, i've no quarrels with Dell, i've purchased mostly Dell systems for my business, over 20 or so systems to date... and they have been doing well for my uses.
but the frustration with the m6400 is begining to wear down on me.
i make this thread and hope that someone from Dell becomes more aware of the situation.
it seems that the m6400 with the 3700 graphics card has brought many woes to owners who utilizes any program that uses 3D accelerator...
in my brief review of the threads here, it seems that the only resolution is like playing a lottery... get the card replaced... and see if it works, if not, repeat... some works after one, some after numerous replacements.
it also seems that this issue is not related only to games such as WoW or FFIX or Guild wars, there's been issues reported with Google Earth, as reported by fellow NBR members, SolidWorks, and by other dell users who have responded to my post on their "support" or rather, "support-less" forums...
now firstly, i am not bashing on dell... as a matter of fact, i have nothing but praise for their service department on the business machines... they've been quite responsive and the quality of service is excellent... just that the resolution of the problem is very disappointing to say the least.
in my experience, the crashes happen most frequently during WoW and also happened while i was installing a program and even in google earth... but it was very random...
i'm sure it's basic tech service procedure to have me check external monitor, fine, then they asked me to reseat the LCD cable.. hmm... i'm being asked to go inside my computer?
i've asked them if it will void warranty if i do this... answer is no... but i still felt that ANY customer should not have to disassemble their machines to make it work...
well, they scheduled a repair, replaced the graphics card and now... it's more frequent.
on a side note, i have to say, dell pretty much sucked on the packaging of the replacement card... the fins were pretty dented on 3 locations... seems that the packaging failed to hold the card in place.
well, as i was saying, it fails more frequently... so far, it failed over 10 times... in frustration, i don't even check the machine... and resorted to using my old one.
now i'm scheduled for yet another replacement... i hope for the best as i am really pleased with all of the other aspects of the machine... except, of course, the power brick... who can have any love for such a big ugly thing?
i am contemplating a requesting a full refund or even asking to replace the quador 3700 to the new ATI card...
but in the end... it's definitely not what i have paid good money for...
the resolution is pathetic... try and let's see? now i have to take off another day off work and schedule an appointment with the tech...
wonder if dell is going to reimburse me for my use of personal day?
wonder if i can charge dell my regular hourly wage when i perform these tasks...
anyway, next week, new card... new hopes? well... let's see...
and as for those who ask... why did you get a workstation lappy and complain it does not game well?... it's not really just a gaming issue... any machine purchased by the end consumer should come as a full working order for the ENTIRE package... fine, show me the disclaimer that says, you cannot game on this machine... and i'll stay quiet...
what do you guys think? should i request for refund or request for the ATI card?

My XPS 17 screen sometimes goes black like the display is turning off when using USB sticks, SD Memory cards or even an external Mouse. If you move the mouse it will resume but if you pull out the USB drive again it will go black causing you to have to move the mouse again. Even using programs that use the User Account Controls will cause it to go black (unlike how User Account dims the screen) causing you to have to move the mouse to bring the screen back.
The only way to stop it from going black is rebooting, until it decides to do it again. However even if you aren't using a USB anymore after it started going black, it will go black at random even when using the internet causing you to have to reboot. It will only do this if the USB or user Account has triggered it going black first.
Sometimes this doesn't happen for a week or two and sometimes it happens a few times a week. Dell has replaced my motherboard and my Graphics card with brand new ones. It seemed to have fixed it until it did it today (week later)
I don't believe it is software related as I have all the latest bio updates, driver updates and windows updates.
I tried something I've never tried before. While it was going black using USB drives I tried pulling the battery charger cable out from the back. When I did that, it completely stopped going dim without a reboot. I've never tried this before and no matter what I tried before doing this the screen would always go black.
Could it be my Power Cable that charges the laptop? or could it be my display? It seems it's related to the charger because me unplugging it seems to have fixed what ever was messed up until it occurs again at random.

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.

Black Screen: [URL] ...

I thought before maybe its Bluetooth related as sometimes when screen would turn black and then come back, I would get a 'Bluetooth Device Not Discoverable'. So turned off Bluetooth in the BIOS, but still having display/sleep issues.
I removed hte Lenovo Power Manager/PM Driver, and turned off sleeping in the Windows power settings (in every setting including if Low Battery Action).

First of all my laptop is : HP Pavilion dv6-6160se Entertainment Notebook
Â
To the problem now : A few days ago my laptops screen started  out of a sudden shutting down/turning black( no lights at all ). This was happening while using the laptop at random. The screen  had no lights, and if i use a flashlight on it there is nothing. like its turned off completely.
Before this happens. This behavior varies. Sometimes it flickers from my desktop to a black screen then back on and some times not. Most of the times screen changed to a random color (green mostly)Â then becomes black/shuts down.
NOTE: The laptop keeps running, i can hear the videos playing so it probably isn't a gpu chip or gpu issue , music and games.
Â
Here are everything i tried and all or the details i could accumulate in past couple of days:
Â
1. If the screen flickers , blacks out and then turns back on i get a message that gpu drivers have stopped working and recovered ( Â on both amd and intel ).
Â
2. If the screen blacks out, on rare ocasions if you close the laptop lid and let the laptop go to sleep , when waking up screen works again ( noticable due to screen moving)
Â
3. I tried installing 4 different drivers all with clear install. ( didn't work)
Â
4. I tried to  to recover system with restore point. ( didn't work)
Â
5. I tried to lower the screen brightness. ( didn't work)
Â
6. tried this trick:Â Turn off laptop.. Remove battery.. Hold the power button for 30-45 seconds.. Plug-in the charger ( don't put the battery in )Turn on laptop and see if it works.Â
Very Noticable details:
Â
7.  Since  on of the rare fixes requires to move the lid  i tried shaking the screen a bit or pushing it slightly to different directions. This actually  does the trick and turns the screen back on ( i am right now typing  this after using this "trick"
Â
So, with this one as a hint there are a couple of stuff i have in mind but i am not sure ...
Â
a) There is a loose LCD cable and when i type a little vibration moves it and ends up in a black screen.
b) I read that if you use a flashlight and you cant see  your desktop it means its a bad inverter.
c) Can the inverter have a lose cabe instead of the lcd ?
 Â
Currently the screen looks ok ( maybe its the certain angle it has after i moved it. Tried to play a game for a few mins and i got the black screen again. Closed the lid  so the laptop goes in sleep mode then opened it and it worked. Just for the records.
Â
Just tried to play a game again. got the blackscreen, shaked the screen a bit and it worked but for the 1st time i get the message "Â Application has been blocked from accessing graphics hardware" , Can it be that its the GPU after all or maybe drivers?Â
Â
Tried to play a game again and it seem to trigger the issue . ( i am currently running the laptop with only the intel drivers installed) ...

Why not share how 7 run on our precisions m6400 ?
I'm using win 7 build 7048 x64 working really well (way better and faster than XP sp3, however I never thought to use Vista..).
there was some issues with build 7000 and Adobe CS4 production apps (like premiere, encore, AE) now solved with 7048
The only nvidia driver I found working well are 179.44 for Win vista x64, installed without modding nv_disp.inf
the one provided from windows update for 7 (179.43 win7 i think) was not working (the screen turn white).....

I have a Studio 1558 laptop running Windows 7. Recently, when I open an application (ex. Microsoft Word, McAfee, Excel), the screen fades to black, stays black for 2-3 seconds, then pops back up. It has happened at a few other times too, but I don't recall the specific circumstances. The laptop is 2 1/2 years old, unfortunately out of warranty ....

my laptop started acting REALLY weird about a week ago. While I am using it, seemingly at random, the screen 'flickers' and freezes up, and the only way out is to hold the power button to shut down, and then restart.
I have included a picture of what it looks like:
I also noticed that the speakers sort of emitted a 'staticky' sound as this happened, although this could just be because the computer stops processing the sound data.
Anyone ever experience anything similar??? What to do?
Also if I check the Windows Event Viewer after restarting, it logs nothing at the time of freezing, no errors or anything.
The laptop runs sort of warm, but never part 66°-69°C
It has: Windows Vista SP1, AMD ATHLON X2 1.6, and 2gb ram.

I have an Acer Aspire E1 model Q5WPH, runnng Windows 8. All has been well until this week when the screen began flashing random colours.
Â
I powered the machine off and from then on it refuses to boot back up. Power appears to be getting through as it starts up the DVD drive but then the power light goes off - then back on and the process continues until I power the machine off again.

I am having a bad blue-screen issue with my hp dv6-1245dx laptop. Â I am crashing to a blue screen at very random times, starting with one occurence a few months ago, followed by two months with no problems, then a few crashes in a row three weeks ago, followed by three weeks of good use. Â In the last three days the occurences are pretty much every 10 to 20 mintues, at random, and they require a few minutes of waiting before it will crank back up again. Â ( Â If I don't wait this short time, it will crank but it throws a black error screen saying "No operating system found" )Â I fear it is some failing hardware issue, like the HD about to give out. Â I have run the Image Diag.exe from the first post on this forum, and have that log cab file available. Â I also have an image of the blue screen ( it is the same each time, the error is a STOP: 0x000000F4).

I was browsing the internet a day ago and I was on a "COLLEGE" website so i know this is not due to a virus. At this time all of a suden my screen went black.
I powered the laptop off and turned it back on, The Dell logo appeared but the screen was fuzzy and had some "tearing" i dont really know what to call it but it doesnt look right. Kind of like an old VCR playing videos. The screen then whent black after the windows xp splash screen. The laptop still boots to windows but it does not display anything.
I booted into safe mode, everything functions correctly and the way it's supposed to. I then booted into VGA mode same thing everything functions and works the way it is supposed to. I also ran some virus scans just incase, nothing was found.
Whilist in safe mode i changed the resolution down to 800 x 600 and still no luck after booting in regular mode.
In VGA mode i tryed to change resolution and the screen displayed some blue fuzzy lines then whent black.
After this I booted back into safe mode and done severeral diffrent System Restores at diffrent dates. Still no luck
After going through all this I am assuming this is a GFX card problem. The laptop is about 3 years old and ive played games pretty hard on it ever since. The card has defenitly gone through some some stress. Can anyone confirm this?
I know that the i9300 sells for about 400 working, and i checked on ebay for a card that is a whopping 180 bucks. Id just assume buy a new laptop. Then sell the i9300 laptop for parts because everything else works fine. Or maybe buy the card swich it out and sell it for a price. Maybe there is a way to fix it i dont know. can anyone help?
Lastly, i thought i would add that when i check the bios the card is recognized and it displays all the correct info for the card. IS there a way to tell for 100% that the card is bad?

When I put my laptop to sleep (to RAM), after a while it automatically suspends. Then, when I wake it up,
it goes to bios, the resuming windows screen, then blank. To make the screen come on, I have to susspend to ram again, then wake it up.

I'm experiencing a problem with my G500s Touch, i am not touching the screen but it makes a lot of random inputs and appears contextual menu (like right click). It's really annoying, one of these days i'm going to throw this laptop through my apartment's window.
Â
I already opened device manager and deleted all HID interfaces and reinstalled. Reinstalled Elan Drivers (i think maybe it is the problem, elan driver), i used windows restore 3 times and i still have the problem.
A Quick solution for this: Ctrl + Alt + Del, then Escape. And you will not have this problem in the next 1, 3, 5 or 10 minutes.

Has anyone successfully calibrated the RGB LED screen on the M6400 Covet using a colorimeter?
I have a Pantone Huey Pro and I'm getting really bad results after calibration (washed out colors, greenish cast). After about 2 months of back and forth with Pantone they have told me that "maybe" my colorimeter doesn't have enough range for a screen with such a wide gamut.
The "maybe" part, which suggests they don't even know their own product, is what I find unbelievable

This is driving me crazy. The left rubber bumper on the keyboard deck of my m6400 keeps coming off. I called dell and they ended up replacing the entire deck just to replace this one little rubber piece and it just ended up coming off again.
I really don't want to call dell and set up a service call just to replace this one little piece. The last time I did the tech completely disassembled my laptop and it took him 3 reassembly attempts to get it to boot,
but I'm worried the my screen will get cracked if I don't (I have the covet with the glass screen). Seems like a really bad design.

I can't seem to find out if the screen is Matte or Glossy?
From what I've been reading the screen in the covert is way too glossy so I want a Matte screen, but still LED.

***I should also note that some of the close screen shots are a little blurry. I wasnt using a camera stand and taking shots with no flash. So like in the sunset shot, dont compare resolution cause the m6400 pic looks blurrier than the 9100 pic. Just compare color and brightness. Sorry, I just noticed this hours later *
Ok, Ive taken some side by side pics.
Old laptop, Dell 9100 15" about 4.5 years old.
New Laptop - M6400 Covet
As you can see, for me at least, buying this 17" isnt much bigger than the
15" Im used to. Ok, yeah. I wish the power supply wasnt so big but I will still carry this daily with me to work.
I have a backpack by Spire that I LOVE. They make a sleeve that fits this laptop fine and though the backpack I bought isnt SUPPOSED to fit that big of a sleeve, it actually works.
I highly recommend Spire backpacks. My old one for the 9100 has been carried almost Daily for over 4 years with good weight in it and it still really seems like new esp in the strength department.
I am no expert in video card and monitor stuff as Im an audio guy, so I havent tweaked anything with these screens. They are just both set to highest brightness level and as they came. Im not sure how "fair" it is to compare these since one is an LED screen and one is not and right there, you should expect one to be "colder" and one "warmer".
The LED on the m6400 is definately more saturated with color and way brighter. In whites, my old one looks a bit yellowish though it doesnt really show on the pics.
I tried to so some comparison glossy vs matte (9100) screen. Yep, the Covet is glossy as it IS glass after all, but nope, it doesnt bother me a bit. My first glossy screen too.
I tried to show the screen at angles but both these screens seem to have a wide angle range for viewing.

I'm having some trouble with my m6400, but I'm not sure if its a Dell problem or my gfx card or Windows Vista itself.
Whenever I start my laptop the screen resolution gets reset to 1024x768, and I need to manually re-configure my screen.
Does anyone have an idea why this may be?

is the sony FW35V(customizable) on the sony style uk site a 1920x1080 a dual lamp LCD?
it says 16.4" H1080 WXGA++ (1920 x 1080) Widescreen X-black LCD screen with built-in "Motion Eye" Digital Camera, but is it a 1920x1080 dual lamp, multiple lamp(how many?) orr single lamp? make sure its the fw35v not the fw35x. the fw35v is the one that costs £60 to upgrade the screen. the fw35x says HD1080 (1920x1080) X-black LCD with multiple lamp, which im guessing is a dual lamp LCD right? also is the Dual lamp worth it for £60?
what does it do? give brighter?, sharper?, more deep and rich colours? or something else?

I have pavilion dv7, so far I had no problem. Now, when I login it logs in but then instead of showing me the home screen, it goes into blank black screen. It has just started to happen and I hope there is another way to make it work without rebooting the whole system.

17" UltraSharp™ WXGA+ (1440x900) LCD Display
NVIDIA Quadro FX 2700M, 512MB Discrete
Windows XP Pro
I got my Dell M6400 in about 10 days ago and immediately noticed a bluish/purplish tint in the grays. I compared it to my other two laptops and several desktops and it is definitely off. I connected my desktop monitor to the video out on the M6400 and it looks like it is suppose to.
After trying about everything possible, I contacted support and they immediately sent someone out to replace the LCD. The tech noticed it as well and agreed that it was not (or at least should not) be normal. I have never seen a screen do this before.
At any rate... Dell is sending me a new machine, but I am worried that this might be something that is inherent with this video card and LG screen combination.
I simply cannot imagine this being inherent and Dell allowing laptops to go out with the problem. I can't even imagine how they could have tested the screen and not noticed the problem.
