Precision M4400 Owner's Lounge *Part 2*

Anytime you want to trade (straightup) LED WUXGA for DualCCFL WUXGA let me know (I'll even pay shipping!) I wanted the LED backlit, but received the DualCCFL.

Hi all,

I have a problem that is driving me crazy. It just started in the last month after I accepted a video driver update that Vista was offering as part of Windows Update.

Basically, every time I undock the M4400 from the port replicator the LCD panel dies and will fail to show anything thereafter. So I have to hard reboot before it will show anything on the screen. This absolutely ruins the usability of the laptop because I dock / undock as a regular part of what I do every day.

I saw in the recent nVidia driver update release notes on the Dell site:

However installing the driver did absolutely nothing to fix the problem for me.

Has anyone else been experiencing this? Any ideas on anything to try? I dread calling up Dell support because they will probably make me install 17 other drivers and god knows what else they will break in the process

 

I had the same issue even I had FX770 and T9550. I am using original Dell DisplayPort->HDMI adaptor.
Actually in my case it does matter only on nVidia driver. When I used original nVidia driver (I mean the one downloaded directly from nVidia web) the audio doesn't work. But with branded DELL nVidia driver it works perfectly. I didn't test it with the latest graphic driver on DELL M4400 driver page, but the previous one helped me.

 

thanks guy!

 

the quality of the led 1440x900 display is good ??

how much % of coverage adobe rgb have it ??

 

Before M4400 I had Dell XPS16 with RGB-LED and some colors were oversatureted, especially RED. There didn't find any way how to correct it into normal leves (windows color profiles, driver settings). And second negative aspect of that display (for me) was very high resolution 1920x1080 which was absolutely unusable for my eyes on 16 inches LCD (everything was too small).

Now I have M4400 with the resolution 1440x900 and the size (DPI) fits perfectly for me. The colors are like normal TN LCD so nothing special. Four years ago I had Asus M6 with glassy and glossy display (1280x800) and it had much better colors and contrast then my M4400. But I can not have everything :-(

I have no experience with WUXGA 2CCFL but it has probably the same colors and little bit better contrast. But the high resolution is unusable on 15.4 inches from my point of view.

 

Running W7 x64 and a Q9300 processor.
I notice that none of the cores are ever in a parked state.

Anybody with Win7 see core parking working?
(Open Resource Monitor and watch the CPU state, when parked the CPU name will say parked)

 

Look at Weegie's last post here:

Thanks so much Mike, you were right! I have actually taken an M4400 mostly apart before to apply AS5/enhance thermals, but I was kind of pissed that this new keyboard developed a problem so quickly.

 

you're actually supposed to remove the battery and release the clips for that strip, if you pry it off from the ledge near the insert button you risk damaging it.
