M6800 Owners' Thread

Been while since I posted. My question is this: can a Precision M6800 non backlighted keyboard retrofitted with a backlighted keyboard, will it work.

 

Yes, just remove the old keyboard and install the new one, very straight-forward. You have to remove the keyboard trim, then take out five screws, and disconnect the ribbon cable.

 

Got a M6800 to replace my M6700 with IPS Screen. The M6800 Screen looks grainy compared to the M6700. The M6800 screen is a Red Covet 17.3 inch UltraSharp FHD(1920x1080) WideView AG LED-backlit Multi-Touch Premium Guarantee.

I have the K5100M video card too. Is there anything to make the screen better. Dell may replace with a 7710. Are the 7710 screens better?

thanks

 

What screen model do you have?
I have an m6800 + firepro m6100 with the regular WideView FHD display (eDP). It is an AUO B173HTN01.1. Out of the box it was way too blue, but after color correction it looks much better. While it isn't fantastic looking, it does look fine as long as I am not too close to it. If I sit too close (<1 foot)I can see what looks like vertical lines between the pixel columns.

Also, the intel and firepro gpu's use different kinds of dithering. With intel active the dithering is static, whereas with the radeon I get some sort of temporal dithering. I usually prefer the latter. I remember in Linux when I had nvidia that the nvidia-settings app had different controls for dithering - I don't know what OS you are using but check nvidia's control panel for that; it may help with your graininess issue.

I've also thought about selling this machine in favor of the 7710's and its IPS screen, but I'm waiting for Thinkpad P70 FHD reviews and the 7710 Thunderbolt availability before deciding.

 

7710 screens are quite a bit better, especially the 4k IGZO.

Are you sure you have eDP on the m6800??? If that's the case, the 7710 screens should be a drop in replacement. I'm searching for a thread discussing how we use the 4k IGZO display on the m6800

 

Unforunately it's not drop in, even though it is the right interface . I thought it would be a drop in when I bought the m6800, hence me considering swapping it for a P70 or 7710...
The mounting for the m6800 screen is completely different than the newer screens. The newer ones use four 'tabs' with two holes each on the top and bottom, near both sides. The m6800 screen is the older kind where the screws go into the frame of the display on the side.

You might be able to use 7710 screens if you *really* modded the lid of the m6800 though...

Newer screen mounts look like this, and some even have the edp connector board hanging out past the bottom of the display:


Older screens like the ones in the m6800 look like this:

If the screen otherwise fits in the frame, can't you just cut those tabs on top and bottom?

There was a similar mod for Sony S13 where a Lenovo Yoga IPS screen was used and you had to cut such tabs off and make the display cable longer as the connector was on the left side (fortunately, there was enough cable supplied with the laptop, but it was folded behind the motherboard).

 

Yeah those tabs should come off easily enough with a dremel tool, but then you have to deal with the lack of mounting holes on the side of the LCD. The m6800 has metal brackets on the left and right side of the LCD that screw onto its sides, and those brackets in turn get screwed onto the lid of the laptop.

 

This is really strange, do some m6800 have eDP and others have LVDS??? I know my m6800 with quadro k4100 has the 40pin LVDS connector AU OPTRONICS B173HW02 V.1

If electrically we can connect a 4k eDP to the m6800, I'm sure we can figure out a way to mount the screen securely.
