Qosmio F750 - some keyboard keys stoped working

Hello
I have a Toshiba Qosmio F750 since 3 months ago. The other day, i just powered the laptop and noticed some keys (a,b,n,enter...) were not working at all. I tried to clean blowing under the keyboard and nothing. Also in the windows booting these keys dont work. Anyone with the same problem?
Someone knows how to solve this?
Is quite annoying having to use an external keyboard with a 3 months old laptop....
thank you!

Hi
I think only keyboard replacement could solve your keyboard button problem.
It looks like the single buttons are faulty and since the single buttons cannot be removed, the whole keyboard needs to be replaced.
Get in contact with an local Toshiba ASP. The warranty seems to be valid and the fix should be done free of charge sorry to say this but it seems you had simply a bad luck :(

    Hi lialou,
    I got your message about the new keyboard failing.  I would recommend doing a full System Recovery to see if that restores the function back to those keys.  Make sure that you back up your data beforehand.

    If that doesn't work it could be an issue with the connecting cables and you should give us  a call regarding repair options.  You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

  • Pavilion 15-b142dx Some Keyboard keys not working

    A friend gave me their Pavilion 15-b142dx  sleekbook, apparently AFTER they spilled some type of liquid in it. I was able to revive the computer, however, there is still a problem with the keyboard.  When the keyboard is installed in the laptop, several of the keys do not work. However, when I take it out (and suspend it with some plastic) it works fine.  I have disconnected the ribbon cable, and taken some alcohol to clean up the area. I have also been able to run the HP diagnostics on bootup, both short and extended versions, and they come back ok.  Additionally, I connected an external keyboard and it worked fine. I have searched the forum for this type of question and didn't see it. Has anyone else had this problem, or am I looking at replacing the keyboard?
    I currently am running windows 8.1. I do not get any error messages, but I did notice HP does not include a keyboard key test in its diagnostics.

    Hi there @MrKen99 
    Welcome to the HP Support Forums!
    I understand that some of your keys are not working, after some liquid decided to pay an unwanted visit to the board. I am happy to assist you with this.
    In my sordid past I have seen some really messed up keyboards, due to similar things, coffee, cola, water, whatever. My most memorable was someone who brought me a computer that was used in a kitchen and was close to a deep fat fryer, and the keyboard was not only coated with oil and grease but a build up of fuzzy dust all throughout the keyboard. In that case I recommended a replacement as the cost to clean it was more expensive than a new one.
    Anyway, it sounds as if you have already tried to clean it, but if you did not pop off the offending/non-working keys, the contacts could be "tacky". Make note of the keys that are having the problem and treat them individually. This document shows how to remove and replace keys from a standard notebook keyboard.
    Notebook Keyboard Troubleshooting (Windows 8)
    If you do not have any success doing that then, I would look at either replacing the keyboard, or using an external keyboard. If you choose a replacement you can look at the service manual for it, and it will list the supported parts.

  • Some keyboard keys not working

    Hey guys,
    I've been having problems with my keyboard in my MB.
    Every now and then certain keys stop working for no apparent reason.
    The keys are:
    Right Shift
    Right Command
    Both square bracket keys
    Equals & Plus button
    The 0 button
    Arrow keys
    These stop and start working randomly, but not all at the same time. However, it is never just one, it is at least 2.
    I have not been able to figure out what is causing this, and a restart doesn't help, after a while the keys just start working again.
    When they aren't working, keyboard viewer doesn't show up as the key has been pressed, so I think it may be a hardware issue.
    My Macbook has never been dropped or had anything spilt on the keyboard.
    Any suggestions would be awesome.
    Ta,
    Ryan.

    Try resetting your SMC and PRAM. If neither work, you may need to get your keyboard replaced.

  • Dv7-3065dx Entertainment Notebook: Some keyboard keys not working

    Hello,
      My hp dv7-3065dx entertainment notebook is missing, (will not type), letters q,w,e,r,u,i,o,p. My knowledge of computer operation let alone technology is scant as I've been MIA for the last 20 years so be gentle with advice please. Thanks Everybody!

    Resolved! The numlock turns on by default when you connect to the computer. Thanks for your question. When I pressed the keys 'iou', nothing appeared on my Dell Optiplex Desktop whereas numbers 456 showed up on thinkpad. The numbers 456 gave away the problem. I still notice that numlock comes on randonly when I plug to different computer. Thanks to all replied. Hopefully, this experience would help someone in the future.

  • Macbook Keyboard Partially stoped working

    ok i have a macbook and the other day my keyboard randomly stoped working. now the FN keys at the top work including the brightnesss, volume, expose, dashboard, ect... but none of the letters work (a-z) also the enter key doesn't work caps lock doesnt work shift doesnt work and so on, BUT the arrow keys work
    i went to the apple store yesterday and the genius told me they didn't know what was wrong with it and to reinstall leopard. only problem is i don't have my second dvd that came with my computer to install all the ilife08 stuff and i dont have the office 08 cd that was provided by my school. so when i got home i plug in my external hard drive which i use for time machine, pop in the disk and do a full restore to 3-7-08 after about 2 hours of it restoring it finally was finished, leopard boots up and finally everything works! so i go to bed. wake up this morning, go to class and i'm using my laptop in class to take notes in word. all of the sudden when i go to type another sentence the keyboard once again dies! i wasn't doing anything on my computer besides word. i believe the only other application i had running was little snich. so now i'm not sure why in gods name this has happened to me 2 times. the mac genius told me it wasn't a hardware problem and most likely software. what could be wrong????
    thanks SOOO much in advanced if anyone can help me

    I can only be of limited help, but I use Little Snitch and it's never given me any problems.
    It's possible that some application is hijacking the keyboard input, but that seems to bizarre. It could be hardware, since the cable that connects the keyboard to the laptop is directly under the keyboard and it could be shorting out intermittently.

  • My backlit keyboard keys not working?

    How come my backlit keyboard keys not working? When I try to use them I get a circle with a line running through it?

    cpickrell wrote:
    Jax, the backlight is currently usinig a sensor to turn the light on and off for you. This uses the least amount of battery. If you want to test or control the lighting yourself, go to the Apple Menu, select System Preferences, click on the Keyboard icon. Here you can turn the automatic setting on and off. If it is off, you can use they keyboard keys to turn the keyboard lighting on and off.
    Exactly!

    Hi l, and welcome to Apple Discussions.
    I agree with captfred, you definitely want to run that update, and then repair permissions. If that doesn't do the trick, try removing the batt and running. In some cases the batt causes pressure on a cable between it and the inside of the MBP case, resulting in keyboard/trackpad issues.

  • Keyboard key not working

    Hi
    I left my mac over the weekend and not use it at all and I came back after the weekend to find that my 't' key isn't working. It works on my wireless keyboard so I am guessing its an error on the key but I have never know it happen to just a single key? I checked and the key isn't jammed.
    Can anyone help with how I can fix this or is it gonna be a trip to Apple to get them to fix it?
    Cheers

    Please give me the possible solutions for this problem..
    If this is in warranty you should get it fixed ASAP and if not you will have to get a USB keyboard to test whether or not the fault is the laptop keyboard or the system board connections to verify the problem. If the USB keyboard works fine for all keys then you need to replace the laptop keyboard.

  • Some keybaord keys not working after suspect virus on Tecra A

    Apostrophe, delete, semicolon and end keys not working after a suspected virus attack. I found record of the same problem on the net but apparently this guy fixed his problem after he found scroll lock or num lock on.
    This is not the case here but there is something going on with numlock - register shows 2 and not 0. change to 0 but when reboot back to 2 again.
    Suspect changed back by bios. I thought i couldnt get to bios because DEL key not working but found ESC works.
    Tried to reset default values for bios but then cannot save and exit as this required the END key to work.
    I was running XP at the time of the (suspected) attack and could not rectify the problem so put the computer back to the OEM status which i hoped would help - it did not, same problem so rather than install all the software on the computer again with XP i upgraded to Windows7 - fresh install.
    Still keys do not work - it was a real pain to start with as my computer was set up to ctl+alt+del to log in and i had to do this with on screen keyboard - XP - this also showed that numlock was on before and after windows boot.
    The reason i suspect a virus - my wife was watching one of her tv shows on line from home country (another toshiba laptop) and i needed to use that laptop for something else so i asked her to use mine - later on we turned the laptops off and in the morning turned tham back on again, the other laptop with AVG virus protection flagged several hits and this one with (FAMOUS and completely up to date) Norton flagged nothing - once i got into it using on screen keyboard.
    Problems with this computer was found after scanning with a different antivirus.
    Anyway - i am left with 4 keys that do not work on my keyboard (actually they did work after i logged into the computer for the first time but i had to hold them in for a long time - and then next time i rebooted, not work at all and havent ever since)
    Any assistance here would be greatly appreciated, i have been working on this all weekend with no joy at all.
    Thanks in advance.

    Thanks Xardas,
    I have essentially done both - tried Toshiba OEM status found on a small partition of the toshi hard drive - no good - then did a fresh install of Windows 7 - still no good
    You know - as cunning as it sounds - i cannot reload the default settings in BIOS as it requires the END key to work so i can Save & Exit - all i can do is Exit Without Save - i sort of feel snookered at the moment.
    Toshiba got back to me today and said that i have tried everything they would have (yeah for sure) and to take my machine into a service centre for a hardware check - yeah right on boys!
    Check out this guys post below found on Kioskea.net - getting close to a year ago...

    Hi there, I was hoping that you might be able to help me with the problem that I seem to be having with my Toshiba Satellite Laptop Keyboard too. For a few days now I havent been able to use a few of the keys on my keyboard, including (1) delete (the backspace key is still working though), (2) colon/semicolon, (3) apostrophe/quotation marks and (4) end (the home and PgUp and PgDn keys are still working though). Any suggestions?
    Identical to my problem....obviously this guy had the same problem as well...see below - same thread.
    yab - Feb 9, 2010 4:47am GMT
    hi did you ever figure this out? i have the same exact problem...
    However, i was not able to solve my problem the way this guy did - my scroll lock is not activated - it seems to work ok (on and off) i tested it using Excel to move around the cells.
    yab ms ml - Feb 9, 2010 7:57am GMT
    Nevermind. For me it was scroll lock. My apostrophe, semicolon, and delete keys are alive and working again. I hope you have the same easy fix.
    Incidently - never hear from the first guy again - probably ended up being his scroll lock.
    all sugestions welcome - sorry my smily face has no eyes -) guess why!

  • DV7-3112sa keyboard keys not working

    I might be blind and missing an older post on this but the 'q' 'w' 'e' 'r' and 'u' 'i' 'o' 'p' keys are not working.
    I was typing something then all of a sudden these keys didnt work anymore. I tried the old trick of turning the laptop off and on and taking the battery out but that didnt work. The system says that the drivers are all up to date and working.
    Unfortunately this is where my technical skills run out. Any ideas as to why they stopped working, and more importantly how I can fix it, would be greatly appreciated.
    Thanks
    Andy

    Go into Device Manager, uninstall your Standard PS2 Keyboard and then reboot.  That will reload your keyboard and hopefully it will work properly.  If not, get a hold of a usb keyboard and see if you get the same results.
    Please post back whether it works or not.
    Good luck

  • Qosmio F750 Toshiba applications have stopped working suddenly

    Hi there,
    can anyone help me?
    All toshiba applications in my Toshiba Qosmio F750 have stopped working. Including Toshiba bulletin board, tohsiba blu-ray disc player, toshiba reeltime, etc... I don't know why and when it stopped working... please help me anyone :(

    > I don't know why and when it stopped working
    For us here on this forum is also not easy to understand what is the reason for your problem.
    For that reason I also think best and of course the easiest way to fix all this is OS reinstallation.
    Start to use your notebook with factory settings again. With clean recovery image installation everything will be perfect again.

  • Usb keyboard keys stop working after 10 minutes on mac mini osx lion

    I am using a mid-2010 mac mini with opitical drive, updated to OS X Lion. Within the last two days I noticed a certain section of my wired keyboard eventually stops working. These are the right arrow key, as well as the 1, 2, 3, zero, period and enter keys. The virtual on-screen keyboard works just fine. I've come home from work and powered the mac and all keys work fine for ten minutes so it can't be that the keys are worn. I was going to take it to Apple Store genius bar but now I can't tell if it's the hardware or the lion software that's buggy.

    I had terrible problems last year with the USB ports on my 20" display. They were made worse when I installed a USB 2.0 PCI card in my G5.
    At the time the advice I got was that I should avoid using the display as a USB hub. Apparently the ports are only intended for devices relating to the display (whatever that means). Ridiculous if you ask me. I succesfully use my Cubase SX dongle in the back of the display but that's all.

  • Some USB keys not working on HP Elitebook 8770w

    Some USB keys (32GB) isn't recognised in my laptop. On other cemputers they just work properly. I tried install chipset and USB 3.0 drivers but it didn't help. What can I do?
    P.S. older (smaller) USB keys work OK.

    OK, I'm sure you've tried different USB ports on the notebook and no luck. Correct?
    Also, Try this . Go to your Device Manager and delete all of the USB ROOT HUBS. 
    After that restart the notebook and it will install them automatically. Try using the Drive again and let me know the outcome.

  • Keyboard keys dont work in Mac OSx

    The following keys suddenly stop working and then continue working randomly: F1 to F7, but the F keys work (eg to show desktop) and also the right (and only the right) shift key.
    This does not depend on what software I have running and happens very very frequently.
    If I bring up the Keyboard Viewer when the problem exists, the keys also dont get registered on the keyboard viewer.
    This is really annoying and happens in Mac OSx, not in Windows - although volume and brightness keys dont work (all the time) in Windows - less of an issue though.
    Any suggestions??

    I'm having a similar problem. But it is not intermittent, they just don't work.
    What can I do to fix this? If I use my wireless keyboard, it isn't a problem. Just when I use my laptop by itself...
