Latitude E7240 and E7440

So our account manager (I work for a large uni who deal with Dell) today said the 7240 and 7440 are being replaced with the 7250 and 7450 starting January. Anyone heard anything about them? I can't find anything anywhere.

 

Hello did you find a method to do this and a cheap place to buy one. I am trying to do the same thing, I would like to spend around $100 and try to get IPS as well.

So far this is all I found Whoelsale Brand new A+ LP125WF2 SPB1 Laptop lcd led screen 12.5" IPS led display 1920*1080-in Laptop LCD Screen from Electronics on Aliexpress.com | Alibaba Group

Here is the information http://www.panelook.com/LP125WF2-SPB1_LG Display_12.5_LCM_parameter_23371.html

The only thing I am worried about is losing my warranty.

 

Hi I have the 1080p touchscreen e7240 (albeit glossy) so right now it is fine since I work from home most days with no bright office ceiling lights. It only bothers me 4 times a month when I have meeting so I haven't had time or a major need to switch it out.

When I've done something like this, I always keep the original screen/parts and if I ever need warranty support I put them back in and it does not void the warranty if you do things carefully and professionally. Good luck.

 

I've disassembled the entirety of the e7240 and there's no way for them to know you've disassembled it, unless you mess up some screws.
Mine event had a mounting point broken under the volume keys... I guess from over tightening.

I'd be more concerned about the screen fitting.

 

Yes thats true. the 7xxx series is being refreshed with Broadwell CPUs and preliminary Intel benchmark results show upto 16% performance improvement over Haswell.

 

That sounds pretty interesting, I'm curious about the new battery life and whether they'll be intelligent enough to keep 2 RAM-Slots & alike.

I can't really see the point of all manufacturers going more and more down with potential performance. I get that they can't keep everything as upgradeable, when people want supermegaultra thin laptops. But not even offering 16GB and a strong i7 soldered on board just is beyond my understanding.

 

For anyone running Linux, there's a patch applied in 3.17.4 that works to fix some of the jumpy / erroneous behavior of the touchpad:

    Input: alps - ignore bad data on Dell Latitudes E6440 and E7440
    
    commit a7ef82aee91f26da79b981b9f5bca43b8817d3e4 upstream.
    
    Sometimes on Dell Latitude laptops psmouse/alps driver receive invalid ALPS
    protocol V3 packets with bit7 set in last byte. More often it can be
    reproduced on Dell Latitude E6440 or E7440 with closed lid and pushing
    cover above touchpad.
    
    If bit7 in last packet byte is set then it is not valid ALPS packet. I was
    told that ALPS devices never send these packets. It is not know yet who
    send those packets, it could be Dell EC, bug in BIOS and also bug in
    touchpad firmware...
    
    With this patch alps driver does not process those invalid packets, but
    instead of reporting PSMOUSE_BAD_DATA, getting into out of sync state,
    getting back in sync with the next byte and spam dmesg we return
    PSMOUSE_FULL_PACKET. If driver is truly out of sync we'll fail the checks
    on the next byte and report PSMOUSE_BAD_DATA then.

That's of course, only if you're pushing it.

 

I found this on ubuntu site:

Ubuntu on Dell Latitude E7450 | Ubuntu

Components in Dell Latitude E7450 | Ubuntu

Could this be real!? Is e7450 getting Integrated GT840M!? *prepares bank account for wrecking ball*

 

I see they are sticking with mSATA rather than moving to the newer M.2 format for the small SSD but perhaps that is to retain the WWAN card compatibility (although I see there are also M.2 WWAN cards).
