M4800 Owner's Thread

Actually, the place I've ordered most, laptopscreen.com, has only glossy listed for the QHD. If they ever come back in stock, I'll be trying to do the impossible and upgrade my FHD to it.

UncleWebb - Sorry, bad timing on my screenshots. I'll see about updating my firmware this week and redoing the tests correctly.

 

@Forget64: i read before in this thread that there are too many differences to allow upgrading an m4800 from non-qhd to qhd. If you succeed let me know so i can buy a cheap m4800 1366x768 and upgrade the panel.

 

Well, I've done several other major operations on Dell laptops, and previously worked professionally as a non-warranty technician, so it may not be something most can handle. I'm thinking most likely I will need to replace the eDP cable from the motherboard to the screen, the screen lid back, the screen lid bezel, the wifi/BT antennas, the panel itself, the internal panel mounting/stiffening arms, and the LCD controller board. Probably looking at about 300-400$ in parts, complete warranty voiding, and at least a week of my time (I have a day job, so can only work on this evenings and weekends).

I don't believe another motherboard is needed. The QHD and FHD list the same part number, and the FHD switches from LVDS to the internal panel to eDP connection when you disable Optimus. It looks like the connections are already in the right places, you just have to default to non-Optimus and disable the option. I believe the LCD controller board does that.

 

It's indicative of the mSATA card. I've looked up benchmarks for the lenova and they are in line. 500+ reads, caps at 130 writes. It blows, but I got it cheap and it holds my virtual machines. Thanks for the help and replies.

 

Hi guys,

Has any one tried printing this out so you can use ThinkPad trackpoint caps on Dell machines?

I've tried making a quote via shapeways but I have no idea what the units are as millimetres seems to be too small and metres/inches seems to be too large.

 

Cm maybe?

That's what I thought, but there's no option for that.

 

That's most likely because shapeways expects you to be exporting your own STL from a cad program rather than just uploading someone else's.

Maybe try the 30-day evaluation copy of Rhino 5 to open the file and export in the right units?

This is what I meant, of sorts. You just can’t replace the screen only. Maybe if, in theory, you succeeded in finding a QHD screen with LVDS signalling and with side-mounting and physical dimensions fully compatible with your FHD lid. One cannot just order the usual QHD+ display by Dell part number and put it in FHD M4800.

 

Problems with Premiere Pro and lagging M4800

Maybe you can advise me?

I do video editing daily and frequently I meet lagging, is it the throttling or something else? It occurs on normal video playback and laptop just stops for some seconds, freezer starts and then playback continues. Then I stop the playback and freezer slows down, then it all starts from the beginning cause the video editing is constant start/stop playback process.

Waiting and I thank for an answer,
Mart
