E6440 Owners Thread

The FHD LGD046D really is an awesome display panel. I just upgrade my e6440 to the I7-4610, from the I5-4310. The upgrade made a noticeble difference in response for opening programs, and overall 'Snappyness', and even increased the Win 7 WEI score by a full point on the Win7 partition (have it dual booting Win 7 and Win 10). It boots into full control within 10 seconds with an 850 EVO. This is a rock solid Latitude, and probably the last Latitude version (6440/6540) capable of upgradeable full voltage CPU's.

I really wish they would have configured these machines with nVidia cards instead of the AMD's though. The GPU is soldered, so no hope of replacing it. The revelvant point to the post being: Don't think the Radeon 8690m is capable of ouputting 4K through DP on an eport dock. I couldn't find the full Spec's of these cards to confirm though.

 

Posted this in the E6540 thread. Figure E6440 owners with a dGPU may get benefit from this:

Found this info at AMD's website relating to E6540/M2800 freezing during installation of the latest drivers here.

I followed this info to load the driver listed and was able to reduce my M2800's idle power consumption from ~7.8W to 4.5W. This has given substantial battery life improvements. Maybe E6540 owners can do the same?

Hey guys.

Can you please help me out. I am the happy owner of a dell E6440 for a couple of days now, and I wanna make 2 upgrades to it. I want to change the keyboards to a backlit one (the current one is not backlit) and I want to change the screen to the 1600x900 one (current one is 1366x768).

Can you please tell me what I should have in mid when searching for the parts online? Especially for the screen I read there are 40 pin and 30 pin screens? How do I know witch one is compatible with my dell?

Thank you.

 

You need the correct video cable for the higher resolution screen. The crappy 1366x768 displays use a different cable than the 900p and 1080p displays.

 

Anyone pass me a link on where I can buy a media bay battery for E6440. IIRC the P7VRH does not fit the E6440 unless someone can correct and confirm. All the resellers of the media bay batteries don't list the E6440 just other E64xx E63xx and E62xx modesl.
Also recommendations of a replacement main battery?

Current config is 8GB DDR, orig Hybrid 500GB + 750GB Black in media bay. performance is still acceptable, and don't need to dual-boot into win7 anymore as getting a SurfacePro6 for windows/office stuff. So planned config will be

16GB DDR + 500mSata + 500GB SSD (replacing the Hybrid), and can swap between the media bay battery and 750GB for big wireshark captures...

 

Interesting. Those CPU's are actually getting reasonably cheap. I'm looking at doing an i7-4810MQ upgrade eventually, but upgrading to 4K (dual 4K) screens is a higher priority.

My LGD046D unfortunately has developed a dead "line" at startup. I still have 2 months left on CompleteCare, so I think I will try to get the screen replaced.

I'm still very glad that mine's a pure Intel solution, and not an nVidia or AMD.

 

Dell P/N for the E6440 backlit keyboard is: 04CTXW
Chicony P/N: MP-10F63USJ6981W
Compal P/N: PK130VG3B00

IMHO, the backlit keyboard is a gimmick, but there's the part numbers if you need it.

BTW, hit up Aliexpress or eBay and pick up a roll of Kapton tape when changing keyboards on these laptops. If you don't already have some.

Your laptop would be a LVDS model. Not eDP. So you need to look for LVDS screens.
