E7440 - sleep Issues and display issues

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.

Yup, June 2015 here, It's been a year and then some, and I am still having issues with the laptop shutting down when the lid is closed.


It has gotten to the point where I'll avoid working on sensitive documents while on battery power because I am not sure when the laptop is liable to shut down if my lid is inadvertently closed or if the power button is pressed to put it into sleep.

I caIled Dell tech support who remotely sort-of-fixed the sleep/hibernate issue (where my hdd would randomly start-up and wake my laptop up from sleep in the middle of the night). They changed my hdd settings to turn it off ~15mins into hibernation. I can't remember the finer details though.

Occasionally my laptop will shutdown while hibernating but it's not a huge issue - but still irritating of course. I've updated all drivers/bios etc but the screen flash still plagues me.

Hi

I upgraded from Win 8.1 to Win 10.


It's been a few days now. So far, my laptop is behaving! I just hope it stays this way!


The upgrade to Win 10 was painless. So far all previous programs/apps are working as normal. No need to re-install anything.

Win 10 is a 3gb download.


I say give Win 10 a try.

Regards

I had no encryption on the hard drive and was still having this issue. After a couple of months, I encrypted my disk and the same was happening. A couple of months later my E7440 completely died, and had to have the mother board replaced. Still with the new motherboard, I have the same issue as before: sometimes - not always - when I plug in the cord the screen freezes. Such a pain!

I also had not one but TWO dead motherboards on my E7440, one year apart, and in both cases the sequence was

- use the computer (Oracle Linux 7, with LUKS encryption on both internal SSD and internal HDD)

- close lid (goes into suspend-to-memory)

- disconnect computer from power, put it into backpack

- forget about computer due to going on vacation, battery goes dead in less than a week

- try to resume a week or so later, find that system doesn't power on at all.

...goodbye motherboard.

Happened with BIOS A14, now I flashed the 4th motherboard (3rd one was unlucky and laptop powered off randomly during usage after 2 hours from replacement of 2nd one) with A21 but I will not attempt to reproduce the issue again...

Just a friendly warning for other fellow E7440 users, and perhaps Dell might want to try and fry one for the team? (all new motherboards appear to come with BIOS A14)

Concerning the  mouse issue. Not a permanent fix but I use Win10  and a blue tooth mouse. I turned off the stick and pad  and have not had a mouse freeze or screen lock since.
