Dell Latitude 3540 :: Keyboard - Some Keys Randomly Stop Responding
Dec 17, 2014
We have a problem of keyboard with many Dell Latitude e3540 . Some keys randomly stop responding . We have updated the firmware to version A08 but unable to fix it. Also reinstall the driver keyboard controller with the same result .
The only thing that can solve the problem was momentarily disconnecting and reconnecting the keyboard . Likewise, the problem usually returns . The local support Dell keyboards we changed several times but the problem persisted.
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 have an HP Pavilion dv7 -4053 and noticed this week when entering data into a works database that my right arrow and down arrow no longer respond, up and left work fine. checked drivers etc. Tab had not been responding but is now working.
I bought a Lenovo G580 laptop this march and now I have some problem with my keyboard. It is behaving strangley. Some keys are not responding and some keys are giving me two charecters. For example, when I press T, it writes R and 5 and the key I is not responding. I did system restore, last known good configuration, repair etc, but the problem is still there.
we purchased a few of these units and I would like to have them set so that the wired connection is the only connection showing over wireless but on these units, the laptops are grabbing two IP addresses, one for wired and one for wireless. Is this possible for this model of laptop?
I have a latitude 3540 . Recently I installed windows 8.1 64 bit on it. All the drivers works except the WiFi. When I am trying to install it its showing a message "The installer cannot run on this platform. Pls select the package for your operating system". I tried both older newer versions of the driver package downloaded from dell website.
I just removed the LED dashboard cover and then the keyboard in a LATITUDE E4300 and used some compressed air for a simple spring cleaning. after I carefully put everything back together, the following keys stopped working 9 O L .
I repeated the process a couple of times to make sure I didn't make any mistake, but still those keys don't work.
I bought my ideapad month ago and had some problems. It is gt 755m sli model.
While playing any game my screen goes weird(Picture bellow) and PC doesn't respond at all. Only way is hard restart. this problem shows only while gaming ad just a few times while watching videos on Youtube.
I tried taking SLi on and off. No difference just Fps drop while sli off but it still crashes.
Also I noticed that it doesn't crash so easily without power cable plugged in so maybe it´s something wrong with my settings.
I bought this laptop mainly for gaming so this problem gets really annoying.
dell 5547/win 8.1 touchpad left click not responding correctly randomly, not all times, left click not work and both clicks respond as right click sometimes once or twice a week….or two or three times a day.
latest driver updated and also driver uninstall and re-install OS format and reinstall but problem still there.
I am having a problem with my keyboard on my dell studio 1737. When you press certain keys on the keyboard the adjacent keys are activated as well as the key itself. I've tried various techniques I've read about to correct the problem such as removing power from the laptop for an extended period of time and installing new bios drivers but nothing seems to work. From the information I can gather this is a common problem with this model of Dell laptop. What is the best way to correct this problem. Will replacing the keyboard correct this problem or is there some other problem causing the malfunction?
I have a 3444-CUU that I really love. When I first got it I realised the wireless adapter would just randomly stop working. I updated every possible driver and I'm still having the same issues. All I can do is reset the adapter to get it kicking again. I'm not sure if the wifi care is soldered or if it could be removed or replaced but I'm really leaning towards it being a hardware issue.
It'll either stop working could turkey, won't detect any wireless networks or it'll stop working and I can still view other wireless networks but I cannot connect to them. Resetting the adapter is the only option. As I'm writing this right now the wireless has gone out again. So I have to reset the adapter for 5-10 more minutes of internet just so that I can post this.
I just received the HP HDX16T premium series. and downgrade to Windows XP sp3. Suddenly the keyboard stop responding. All keys are not working all at. It was working fine under the manufacture preloaded Windows Vista home. is there ENE CIR windows xp driver.
i have an acer aspire v5 122P. all of a sudden the keyboard has or is not responding that is unless you hold the relevent key down for what seems like minutes certainly cant type normal speed.
I just bought the Envy 2x 13 Detachable a few weeks ago. I've had issues with the keyboard from day one.
Keys will randomly repeat themselves which makes typing anything, especially passwords, a nightmare. I've corrected that last sentence about 6 times for duplicate characters.
The following sentence will be typed with no corrections:
This keyboard liikes to dupplicate letters inn a totally randoom fashion and I never knnow when it will happpen it just does it.
I saw a thread where BIOS Rev F.08 solved these issues. I have Rev F.06. When I try to install that BIOS I get a message that there was a BIOS read error and it closes.
This is getting VERY frustrating. I've tried adjusting the repeat rate in control panel with NO effect.
My keyboard and trackpad on my Compaq Presario CQ60 notebook are not responding and don't have any external devices to see whether this is an internal matter. Cannot restart in Safe Mode as keyboard does not respond, however it allows me to type in my password to access vista! I think I have just locked the computer, but don't know how to unlock it, various forums have specified reinstalling drivers etc. but I am unable to do this with no working keyboard and do not know how whether I have pressed a combination of keys which have caused this. I am not sure whether this is a Vista problem or a Compaq/HP problem.
I have recently updated the BIOS on my E530 laptop to version 2.08 (the previously installed version was 1.xx, probably 1.37 as far as I remember, but am not sure about the exact version..). After the update the laptop keyboard and touchpad stopped working in Windows.
The keyboard does, however, work in the BIOS and both (keyboard and touchpad) work when the computer enters the Windows-startup-screen (where it suggests to fix hard drive errors etc.).
I am using Windows 8 all along and before I never had problems with my hardware. Now both the keyboard and touchpad are recognized in Window's Device manager, but are known to have troubles. There is also a PCI Device recognized in the category "Other devices", but it's missing any drivers (I wonder if there is a connection..). All those three are recognized as such by the Lenovo Solutions Center as well.
I have tried reinstalling the UltraNav drivers, but it wouldn't work. Also, I've tried finding any possible configuration regarding my problem in the BIOS, but was unsuccessful. If I attach an external mouse or keyboard, they work. I really don't know what else to do to get my laptop's keyboard & touchpad working!
The complete description of my laptop is: ThinkPad Edge E530 (3259-HLG), running Windows 8 (x64).
I just got a refurbished E7440. Before booting into an OS (e.g. staying in BIOS or at the boot menu), and after booting into Ubuntu, the fan is always on high and never stop (even when the CPU is idle at 40 degree C)). I also have an E6420 and an E6440, have never seen this behavior on them.
I see both BIOS A06 and A07 has "thermal control" listed as enhancement. Updated the BIOS to A06, A07, then A08, still have the same problem in all of them.
Is this expected for all E7440s or just mine? What can I do to make the fan be "on-demand" (without using Windows)?
After I updated the BIOS to A09 of the Inspirion 7520 my USB keyboard stop working. All drivers is instaled and the windows recognize the keyboard and the num pad is on its happens with 2 keyboards and change the USB port don't works.
I have a problem with my notebook. When I power my device everything is fine, but after ... let's several minutes sound disappears. The strange thing is that "mute button" on my keyboard is not responding too, when I hit it theres no orange light and one the screen appears a lvl of volume ( normally it should be a crossed volume lvl). When I want to play Spotify or something like that it says that my Audio card is used by another program... The funny thing is that when I did something like "stress test" (I played Spotify when sound worked just after system start) sound was working for about 6 hours and everything was fine.
System: Windows 8 Model: Notebook HP Pavilion g6-2310sw
Also I'd like to add that every system restart fixes that problem but only for a while (several minutes).
I have a latitude E6540 and when I connect a external usb 3.0 disk it begins connect and disconnect randomly. I have tryed another disk and I have the same problem. This USB disk in other latitude E6540 works fine. I have disabled power option in the usb devices and reinstall drivers but nothing solved the problem.
My Latitude E6520 beeps randomly for no reason I can find. It is not the power adapter itself that is beeping and I have had not problems with the system charging and staying charged. I have one charger at work powering a dock and a different adapter at home. The laptop beeps randomly both.
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 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.
My computer will load to the main ID sign in screens, but the mouse and keyboard seem completely unresponsive. The only response I do get, is when the the screen goes into power save, touching the keyboard will cause it to wake up. But that is the ONLY response I can get. How wierd is that? Mouse, on board and external, are unresponsive. I can not so far get to safe mode or anything else, neither F2 or ALT+ F10 do anything on boot.
Previously, I was useing the laptop, including firefox, audacity (minor audio program) notepad and media player. I plugged in my USB mp3 player, and the second I made contact, blue and white vertical lines filled the screen. I forced off, subsequent boots gave only a completely black screen. With instructions from Acer's, I removed all power sources for 20 minutes and rebooted, and now can get to as mentioned the sign in screen, but that is all. Alt and F10, and F2 during boot seem unresponsive. I am assuming that the drivers for the keyboard and mouse are corrupted. I even tried an external USB mouse, no luck. I don't have a UBS keyboard to try
The CD Rom is still responsive, It will eject, and you can hear it reading a disc. Please let me know what I need to try next. IF the keyboard would respond, I could do erecovery, but .. well. No key board. I looked on Acers' site for Kb/Mouse drivers, but didn't see anything, and I"m not even sure how I'd install then from a disc anyway.
