M6600 Owners Thread

I'll get a Flextronics soon - I have my M6600 second hand and it's been heavily modded (CPU, GPU [7970M, not even supported], palmrest, keyboard, screen [same LG though], not to mention mem and drives) so I am not sure the NBD - or any other - warranty still applies (it formally expires in 2015, I think).

Anyway, done more testing with it docked. While I have not been using it that frequently lately - tied to my 12,5" midget -, I still have not seen it flicker with an external monitor. BUT today I tried it for the first time docked yet with its own screen. And it eventually started flickering badly. Then I closed the lid and switched to the external monitor - no flickering at all.

Also, yesterday removing the Delta and then inserting it back again did not cure the flickering as it did a few days ago. It stopped flickering while on battery, though.

Which makes me think it could be a mobo - adapter - display thing, perhaps the Delta causes the motherboard to short the screen somehow?

Weird...

 

I updated to Windows 8.1 from 8 the other day, and what a mistake / regret doing so.. Besides some minor changes that I had to deal with, my Quadro 4000 crashes randomly (there's a pop up that says the NVIDIA card crashed, but it recovered). So I checked and updated to the newest driver 331.82. So hopefully that fixes it, but I'm not sure yet until / if it crashes again.

Now another / the current problem I'm having is with the audio. It stopped working correctly, and I had to uninstall the driver on Dell's website Driver Details | Dell US

The audio works correctly when I just use the pre-built Windows driver (vs downloading the actual Dell drivers). But when I plug in my headphones and then unplug them, the audio stops working correctly (until I restart my computer, then its back to square 1).
When I try and play music from windows media player it'll say "Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."
But if I actually watch a Youtube video, the audio will work (only with my headphones plugged in though).

Note that if I do restart my computer, the audio will work correctly with my laptop speakers and headphones (until I plug in / OUT my headphones). Any ideas??

 

Go back to Win 7? (I am not being ironic; it seems by far the better, safer, more stable option, unless you have a high-DPI screen.)

 

Tested with a Flextronics - same story, the LG display flickers increasingly rapidly, up to the point in which it is no longer usable.

New findings - removing and reconnecting the adapter does not always cure it. Staying on battery does not either. In other words, sometimes they do, sometimes they don't. Flickering happens in W7 and before booting, in bios.

External (dock-connected) monitor never flickered, though.

Otherwise the Dell is perfectly stable, including during load (a la prime+furmark).

 

Well that sucks. I never knew the LG with Flextronics PS - do now, really nothing different from a Delta! It is known that the LG FHD WLED has a flicker problem and I've been thoroughly subjected to it.

Under warranty? then demand: AU Optronics AUO B173HW01 V.5 - 17.3 FHD WLED Matte Anti-glare, corresponding Dell Internal Part Number, Dell P/N: H8D3K

AUO's don't flicker.

I also don't have an external monitor or dock so I'm just going by what you're saying; personally I think the LCD is about ready to toast.

 

I tend to agree with you, and I hope the warranty is still valid.

This being said - is the matte AUO as good as the LG? I know the forum lore is the AUO is somewhat above the LG - but I have a 15" 95% gamut AUO on another laptop and I plainly don't like its saturated colors, even after calibration (and forum lore sings praises to the wide-gamut screens).

The 100% sRGB of the LG seems to me excellent if calibrated, and I like its angles (comparable to the 95 gamut B+RG-LED, which is supposedly top for a TN), blacks and coating as well. The AUO is also 72% aRGB - but are its sRGB coverage, black, angles are coating comparable to the LG's?

 

Maybe some others can weigh in.

Personally I like the AUO for everyday use. Agreed, the LG has some of the benefits you've described and it seemed brighter; that said, I found the feeling of moving icons at higher brightness and lower brightness flickering/blinking unbearable and nauseating. This problem it has, I think, contributes to the deterioration (eventual worsening and breakdown).

I've had a few LG's; Once I plugged in a WD passport and the screen went violent - only cold boot would stop it.

In this day and age it seems pathetic that Mfrs. can't sort these issues and make good screens. Those of us that appreciate them would gladly pay up.

 

I had flickering screen isue and there was no cure outside replacing the pannel. I got my lg pannel swapped for another lg but different revision as auo panel was not availible in eu.

I'll talk to Dell after the holidays.

Though now that you mention it, darkydark, I did swap a panel before due to the "normal" LG flicker and they said the only option was another, similar, LG panel or the 900p version (I had asked for an AUO, knowing that the LG is inherently problematic). They sent this one, and it worked OK for a while (minus the bypassable flicker).

We'll see... Anyway, thanks for your assistance.

 

BTW, would something like a 120Hz LP173WF2-TPA1 fit in the M6600? I am wondering more about the bracket / fitting in than about actual compatibility...
