E7440 - sleep Issues and display issues

Jump to solution

There are three major issues I have with my laptop, and I was wondering if anyone else had them too.. I have not contacted dell support yet, but I will in the following weeks if I don't somehow figure out what's is going on myself. 

I've had my laptop for a little bit under 2 months, so these are the things I have noticed. 

Issue number 1: When you plug in the power cord into the computer, the screen freezes on what it is currently on. I noticed this issue because occasionally when I plug in my power cord, and try to use the mousepad to select something, the mouse pointer is gone! I have to unplug-replug the power cable to get the mouse pointer to show again. I have no idea what the cause of this issue is. It seems to have to do with the screen

Issue number 2: when I carry my E7440 around in my bad, or have it shut for long periods of time >3 hours (I just simply close the lid), the computer will SHUT DOWN. The thing will shut down completly, even though I simply closed the lid! At first I thought it was just going into hibernate, so I disabled hibernate in my power settings. But nope, even when the computer is asleep, it will occasionally shut it self down for no reason at all.

Just now, I closed the lid on my laptop, and put in in my bag, then walked to my office about 10 minutes away. When I sat down at my desk and opened my laptop, to my surprise, it had shut down by itself! All of my open windows, browsers, and applications were closed, and upon opening chrome and microsoft word, I was greeted by "your browser did not shut down correctly" and "microsoft word has recovered files". This points to the conclusion that it was not hibernates fault, but instead a issue with the laptop itself shutting down when it is put in sleep. This issue needs to be rectified immediately if it is a widespread issue.  

Issue number three: When the computer comes back from hibernate or sleep, the computer is very very sluggish, even when plugged in. It is sluggish forever, OR until the power plan is set from whatever it is to "high performance". upon switching to the previous powerplan from high performance, the swiftness of the system is restored. This indicates to me that the system is throttling itself after it resumes from hibernation, for god knows why. This needs to be fixed; many people (myself included) just thought that the system itself was slow and underpowered, not realizing that it was just throttling itself when it emerged from sleep or hibernate.

If anyone has any of these same problems, or knows a way to fix them, don't hesitate to post.

Bobby,

I don't have the same model as you but I have the same problem with the laptop shutting down when I put it to sleep.  I have an Inspiron 17R running Windows 8.1 and when I put the laptop to sleep, sometimes, not all the time, it will shut down instead.  Sometimes it is immediate and sometimes it is after several hours.  I have contact Dell support about this issue (my computer is less than 1 month old) and they have been trying to resolve it, even replacing the motherboard, heat sinks and fan.  Still no resolution.  I would contact Dell support because this is a real issue.

Same here: E7440 shutting down itself, even when i close lid or press sleep.

There are some more issues related to docking station, but this one mentioned above is really annoying.

I'm also running Win 8.1 and the E7440 and have the same exact issue when put into sleep mode and I go to wake it up 90% of the time it has crashed and shutdown.

I have updated all the drivers and BIOS as of 07/18/2014 and still have same issue.  I'm also having the display flickering issue when using the eport dock and dual monitors - this was fixed for a while but started happening again after I installed the newer bios and drivers. I tried going back to the 'fix' drivers and firmware but it no longer resolves the issue. 

I checked the Windows Event Logs and I get this error which I imagine you have also(relating to the sleep issue).

Just chiming in that I have the same first two problems, with a Latitude E7440 running Windows 7

(1) computer shuts down when it is supposed to be asleep. doesn't happen every time, but frequently. and it happens both when the computer is closed but also even when it stays open.

(2) screen freezes briefly -- flickers, goes black, then comes back on -- a few seconds after switching from power cord to battery or battery to power cord.

I'm sad to see no solutions offered here and no luck even from those who have contacted Dell about it.

Exact same issue here.


About time that someone at Dell addresses it.

I've contacted Dell Support Vietnam. They asked me to re-install Windows 8, update and re-install bios. Ask daily working laptop I couldn't re-install it. And I have latest Bios on E7440. This is a hardware error because It also happen on Ubuntu 14.04. When freeze, the mouse still moving but the hard disk light is on. 
I also have another problem that a key usually repeat until I press another key. That is very annoying. I can't return and replace this laptop. Do you have any solution for these?
Dell support is sometime useless although with ProSupport Smiley Sad

Inspiron 15-7537 here. Same issue. I put down the lid. When I open it again, Chrome has been closed. Word and Excel documents are all closed if there has been a very recent save. Otherwise I reopen to a option to save recent work (it is already saved, just open for more than 10 minutes without saving, even when no changes have been made).

I also find it very sluggish after sleep when plugged in. Not when it is not plugged in, which is very odd.

Add to that the very poor performance of the wireless card (Intel N7260 b/g - should be b/g/n according to Dell's spec but they didn't stick to that plan!) and I'm reluctantly returning this after a week.

Be cautious with Dell models - very cautious.

Are you aware of any encryption software on the disk? I have repaired a few e7440's with the same symptoms and have found about 80% percent were due to encryption failure, the other 20% were hardware (motherboard failures).

I have the same shut down issue on my dell E7440.

All drivers and bios has been updated. The laptop shutdown instead of going to sleep.

So far, the time for it to shutdown seems a bit random. Sometimes I close and open the lid after a short while and its fine. Other times its not.


The problem happens whether its on battery or plugged in.

Still looking for fix.
