New M6400: flimsy LCD Panel and Panel Make/Type

Hi all M6400 owners:

The shipping Packing Slip for my unit lists the following for the LCD panel

PRODUCT CODE: U771G
Description: Module, Liquid Crystal Display 17WUX, Red/green/blue,Lg Philips LCD,M6400

Can anyone confirm if that the correct product code for my Original Quote which stated "17 inch Wide Screen WUXGA RGB-LED LCD for M6400 (320-7312)"

i'm guessing that its the RGB backlit display i'm expecting. its NOT the covet model.. and I didn't go with the E2E because I wanted more of a matte display

My other question is:.. is it just me or does the LCD Housing seems to be very flimsy and has lots of flex when lifted from the corners...

Any feedback from people without the E2E... i'm sure the glass makes it more rigid?

Looks correct to me. I have the silver M6400 as well and had the same description for the RGBLED screen. To me, the M6400 is very well constructed. I don't know what you mean by flimsy. I would characterize the lcd cover as pretty solid. I certainly don't think there is much flex.

 

Ok..thanks. I can verify that my 6+ year old 15.4" Inspiron 8600 has almost the same amount of flex from the corners.. so its just me expecting more rigid backing i guess.

on a different note about the RGB LED LCD display..

Do you notice any sort of "auto contrast or brightness" changes whenever you interact with software the switches from black to white backgrounds.... something as simple as open up large menus in an application changes the brightness of the entire display... I notice this when the brightness is up high.. but not when it is set to the lowest brightness level.

 

i had an inspiron 8600 too. i dont know how you can compare the two. the m6400 is a heck of a lot more solid.

what exactly are you referring to as "flex"

 

I'm defining "flex" as the amount of "bendyness" that is observed when you perform the following steps:

1) start out with the LCD panel closed and locked
2) unlock the LCD with the hing/switch/push-button
3) using ONLY the left or right corner, try opening the panel up to 90 degrees
4) observe how much flex or bend there is in the bezel backing to the oposite corner; the one NOT being lifted.

it is MUCH more on the 17" m6400 then it is on the 15.4" i8600.

granted the m6400 is a ligher & thinner LCD pannel, and is supported by a metal allow internals.. compared to the bulky plastic i8600.

the m6400 17" LCD just "appears" to be more flexible.

the alternate way to measure the flex is to push/pull in oposite directions from the top two corners of the LCD panel and observe how much resistance there is to "twist".

I have no fear of opening up the i8600 with ONE hand only on either corner.

but on the m6400 i would ALWAYS use both hands on each corner.. or always use the Middle portion to open the LCD up.

That is really all i'm asking about... I'm not worried or anything.. just commenting about my observations..

Now for something different.. how do I fix the STUPID annoying Automatic Light Sensor behavour.... even with it turned of.. the display is Constantly changing brightness... with stupid things like simply opening up 25% coverage White windows.. it gets brighter, and then dimms when the windows are closed! How stupid is that!

I even checked my Version A07 bios.. and the ALS was TURNED OFF.. and it still has this stupid visual annoyance.

running Vista x64 with SP1, full Windows Update, etc.

Check the options under the dell/windows power configuration. I recall that I had to modify some ALS setting in there to make it stay set correctly.

 

There is obviously still bugs with the ALS option in the A07 BIOS.

Turning the device OFF in the BIOS means the it should never have an effect what-so-ever; The software shouldn't even be able to "see" or control the device with it off in the BIOS.

Has anyone tried to just unplug the sensor completely and be done with it?

Where is the ALS physical Sensor located on the front bezel so I can do some directed flashlight and black-tape-cover tests?
