Dell Latitude E6440 :: Keyboard Generates Double Letters?
Jun 24, 2014
My keyboardd generates double letters (I'm leaving them in as I type to show what II mean). I've searched this forum for similar probleems and have already done the following:
Updated BIOS
Installed/uupdated toouchpad ddriver and input ddriver
Installed touchfreeeze
Unchecked the keyboard driver in device manager andd restarted the computer
None of those steps has solved the problem.

I just got a new Latitude E6440. Overall I love the system, but when it is docked / on AC power, I have noticed that I can almost constantly hear the fan. Right now my CPU is only at 6% but I can hear the fan running. Is that just normal behavior with this system? Does it just have a louder fan that runs more often? I just upgraded from an E6410 and I don't recall ever hearing the fan.
I am running Windows 8.1 Pro, and it is a brand-new install. I ran diagnostics and did not find any issues.

I just bought a new Latitude E6440 Notebook with an i5-4300M and SSD using it with Linux. I noticed that the fan was continuously spinning until I installed the graphics driver from ATI and switched to the Intel GPU.
Now it is off at the beginning but i kicks in when the CPU temperature reaches ~42C relatively loud and cools down the CPU to about 38C. This behavior is very annoying because the fan is switching on and off every few minutes.
I tried to manage the fan via i8k module and fancontrol but there seems to be some control at BIOS level as my settings are always being overridden.Is it possible to change the default cooling behavior of disable the BIOS thermal control completely so I can manage it in software? I tried the Shift+FN+15324 trick but FN+R does not bring up the menu for me. There is also no option in the BIOS where I can change the fan settings. I am running the latest BIOS A02.Is there any other trick to manage/disable BIOS fan-control or is it possible to include the setting in the next BIOS release?

I've had my DV7T CTO for less then one month and the keyboard letters (on each key) are already starting to fade/rub off. This is insane! I suppose I'm going to have to do without a computer now to send this in to get it replaced instead of HP just sending me a replacement keyboard... Why do they insist on everything being sent into them? A keyboard replacement takes all of 5 minutes to do.

I regularly find that, with a single keystroke, my brand new Dell Latitude e5540 laptop randommly produces 2 spaces (most often) and double letters (sommewhat less often than the doubled spaces, but consistently and predictably). The faster I type, the more oftenn the errors occur... I have found it to be an issue of how hard I strike the keys. The keys controlled by my dominant right hand are most often affected whereas those controlled by my pinkie fingers NEVER have been affected.
I amm only one of many employees at my place of work who all are experiencing the same problemm. I have asked repeatedly for Dell to let me know the extent of this problem and whether they have a recall of this model (which, as far as I can tell, is pervasive with this particular mmodel). My persistent questions have never been answered by Dell, despite numerous contacts with 3 different agents.
P.S. If you notice double letters where there should be single letters or extra spaces in this e-mail and this post scrippt, please read on for the reasonn: I am using the brand new Dell Latitude e5540 computer our school system recently purchased to write this e-mail. I have simmply givven up editing my typing... you're getting the spontaneous errors caused by this computer so you can see for yourself and hopefully to motivate Dell to fix the problemm soonner, rather than latter.
IMPORTANTLY, if you are having similar problems with YOUR BRAND NEW Dell Latitude e5540 laptop you specifically will NOT have tthese problems if you use an external keyboard... it only occurs with the laptop's built in keyboard) PLEASE send me your servvice tag (S/N) nummber from the bottom of your Delll LLatitude e5540 computer and I will include your commputer in my conntact with Delll about this problem. (It is a problemm of this particular model... I have never experiennced this before with any other computer).

My qwerty keyboard is not doing or missing many of the letters in upper case - just lower case, and the letter 'L' seems to have given up completely - it will not type neither lowercase or upper case. This problem exists in what seems to be all applications.

I have an issue with the keyboard on my new 15z. The cursor seems to have a mind of its own and jumps all over the place while I am composing emails and letters. This happens at random. What is causing this. I have tried disabling the mouse pad and using a USB mouse but the problem persists. I have tried being extremely careful not to touch the arrow keys located in the bottom right hand corner of the keyboard area but the problem continues

I have only had this latop 3 months and it is missing keys when I type. It isnt that the laptop is slow and needs to catch up, it just misses letters and I have to keep going back over the text and filling in. It gets very frustrating putting passwords in and letters and numbers miss.

My keyboard randomly inserts a double letter as I'm typing. But I do not see a ffix anywhere (just did it again). I've tried changing keyboard settings, downloading updates, etc, etc. This is actually the THIRD HP Envy computer in a row to have this problem.

I cleaned my xps 13 ultrabook last week with foamclene. I didn't spray it directly on to my keyboard but must have had too much on the cloth. Anyway my fn key is now typing letters from the middle row of kes, in varying combinations - jfsda, jfsd, jfs, jfa, jfk. When I noticed, I left the machine upside down to dry out for a few days but nothing changed.

I received my Dell E6400 yesterday and need to take screenshots because I am writing training manuals.
My problem is that with my Dell D260 I could press keys on my keyboard ALT PrntScrn and capture the active screen.
With the E6400 there is only one option to capture screens and that is the Fn key with the F11 which is the PrntScreen button

This is just fabulous. Dell has essentially shut down my business indefinately. On Wednesday, my D630's (my primary machine) hard drive failed. They sent me a "new" hard drive on Thursday. Great. But, it was a "refurbished" drive of a different brand, and something wrong with the bracket fitting left the sharp corner of the bracket sticking out of the side of my computer. Ok, I get yet another on Friday -- same thing. They promise to send me a new bracket assembly along with it, in case the one on the other drive is bad, too. Got the "new" refurb in today. As expected, they didn't include the new bracket hardware, this one has the same problem and, in addition, the thing is a cheapee Fugitsu (my original was an 18 month old Seagate) that is scraped up on the sides and seems to have some of the connectors broke off! Their only options are -- wait for it -- to send me another POS,non-fitting refurb drive, or send it to the depot, where they'll keep my computer for two weeks and send it with the jagged edges of the refurb drive hardware sticking out the side of my lappy.
So, lucky me, I can't play their "refurbished" drive game any more, and I had to pay to order a new one from New Egg. So, now the computer will be out at least a week after the drive failure, and I'll still be faced after a week's down time with rebuilding the programs and data.
But wait, it gets better. I've been working on my refurb (purchased 10/2007) D420 with 2 years of warranty left on it since my D630 went down. As "luck" would have it, the thing is suddenly getting scalding hot on the bottom near the vent, and my PC Card slot has failed, so that I can't get on my mobile broadband. Looks like the darned motherboard on this one is going, and I have to send it into the depot, where I'll likely get more of their "refurbished" (read, "used") parts. 7-10 business days for this one, and now I have no computer, can't use my primary programs, and I've lost tons of data.

Anyone know if there is a way to set the e6400 backlit keyboard to always be on?
I currently have it set to the 5 minute timeout within the DCP software which is good enough, just curious if there is way to always keep it on.

My friend is very cheap and will not get a new computer. He has a dell lat. D520. I wiped everything and installed all the drivers from the dell website for the laptop.
Everything works great until you have to type or move the trackpad. It tends to jump around or insert other letters then the one chosen. But a usb external keyboard works fine!
I called dell and said that he doesnt have any warranty and said maybe the buttons were stuck? Should he order a new keyboard for 50 bucks?

I couldn't remove the keyboard so I turned it upside down and put aside. So from my search in Google I found that I must leave it like that about few days untill everything is completely dry.
I also panicked a bit and it took me about a minute to remove the charger and about few minutes to remove the battery.
My questions are:
1.The laptop turned off - does it mean that it was short circuit or it could be some defence mechanism .....

My keyboard has intermittently been working for some time. When it works, then everything works as it should, when it does not work, the keyboard is still lit up and the mouse joystick still works, but no keys work. To get the keyboard to work again I have to reboot and shutdown many times and eventually it will work again. It only stops working after shutting down or rebooting. To me it appears to be an issue with detecting at boot up. It seems it could be either an issue with the motherboard, or the keyboard so was or to get some opinions on how to narrow it down to one or the other. I should also add, that when it does not work, you can not access the bios, or anything prior to the operating system loading, so I am 100% sure its not an OS issue. I also dual boot this laptop and the keyboard does not work in either. I can plug in a usb and that works fine.

Original Win 8 Pro, then updated to 8.1 Pro, the back lit keyboard works OK. However since I refreshed the system due to the hangs up problem at start up, the back lit key board stops working. Re-updated the OS back to 8.1 Pro again still not solve the issue.Does the backlit key board need special driver ? The device manager shows the keyboard as standard PS2

I tried upgrading my Latitude's RAM using a 2MB chip first in the rear slot, and Win 7 didn't read any additional RAM (showing only 1GB). So I moved the 2MB chip to the MB under the keyboard and now it won't reboot. I tried to put the original RAM chips back in their respective slots (each 1MB RAM) but it still won't boot.
I guess I can't update the BIOS if it won't boot.

I've had my laptop since 2011. Whenever I would press the number 7 key it would repeat endlessly. Also, now when I press a key in the row beneath the numbers row, the 7 repeats itself all across my screen. What could be the problem. Is there a way for me to adjust this problem?

I was recently given a Latitude E6530 and I wish to upgrade the standard keyboard to a backlit one after coming from a MacBook Air. I was wondering, does E6530 (or it's similar models) requires an additional cable to power the backlight or does it just feed off the single cable? I've scoured YouTube and Google to try find out if an extra cable is required for this model however wasn't able to.

I just picked up a e4200 with backlit keyboard and whenever the back light is turned on there is a noise (slight buzzing or hum) that can be heard. As soon as the back light turns off the sound goes away. It's kind of bugging me because you wouldn't think that the back light would add to the decibel level of the laptop..
