Laptop keyboard - some keys not working not

Hello.

I have an acer aspire 3750z (a few years) works on Windows 7. Unfortunately, some of the keys on the keyboard do not work and - oddly enough - when I connected an external keyboard in the same ones did not either use. The others are fine and I can use the keyboard to the screen when I load it up.

I've got either no update of windows due and none of acer. No other problem as far as I know and otherwise good performance.

I also suggest you to update the chipset to most drivers late before you install the bluetooth driver.

You can also look for more updates through Windows updates and try to install.

  • Pavilion 15-b142dx keyboard some keys not working not

    A friend gave me their 15-b142dx sleekbook Pavilion, apparently AFTER they spill some type of liquid inside. I was able to start 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 go out (and hang with some plastics) it works fine.  I disconnected the ribbon cable and took little alcohol to clean the area. I was also able to run HP diagnostics on the startup, short and long versions and they come back ok.  In addition, I connected an external keyboard and it worked fine. I searched the forum for this type of question and do not see. If someone has had this problem, or I'm looking to replace the keyboard?

    I am currently running windows 8.1. I don't get any error messages, but I noticed that HP does not have a litmus test of keyboard in his diagnoses.

    Hi there @MrKen99

    Welcome to the Forums of HP Support!

    I understand that some of your keys do not work, after that little liquid has decided to make an unwanted visit to the Board of Directors. I'm happy to help you with this.

    In my sordid past that I've seen some really messed up keyboards, due to things like, coffee, cola, water, whatever. My most memorable was someone who gave me a computer that has been used in a kitchen and was close to a deep Fryer, and the keyboard was not only covered with oil and fat, but a generation of fuzzy dust throughout the keyboard upwards. In this case, I have recommended a replacement as the cost to clean it was more expensive than a new one.

    In any case, it sounds as if you have already tried to clean it up, but if you do not jump off the keys to delinquency / inactive, the contacts could be "sticky". Make a note of the keys that are the problem and treat them individually. This document shows how to remove and replace the keys on a standard notebook keyboard.

    Computer keyboard laptop troubleshooting (Windows 8)

    If you don't have any success doing this then I would look at the keyboard, or by using an external keyboard replacement. If you choose a replacement you can check the service manual for it, and it will give a list the items supported.

  • some keys not working is not on the keyboard

    Hello

    I have a question on the keyboard of my 7537 15. b n. space downstairs left right and 2 do not work. I tried something like remove the battery and press and hold the Start button in 15 to 20 seconds, or remove the keyboard, but nothing has changed. Please give me some advice.

    Hi Acm06

    Nice day.

    Please write to us.

    When the issue started? There was no incident of liquids lately?

    Please try an external keyboard and see if all the keys are working.

    You tried a power cycle and also re-sitting on the keyboard, there is nothing we can try now, except on an external keyboard.

    If all keys work on an external, then it is a problem with the internal keyboard.

    Please PM US system tag #.

  • MBP 15 "Early 2011: some keys not working not

    Hello Experts,

    I'm on a MacBook Pro 15 "early 2011 10.11.3 on OS X El Capitan.

    Now, some keys on my keyboard doesn't work anymore, only F1 - F9 (F10 - F12 still works fine) and the right SHIFT key.

    I read some other threads about this here, tried SMC-reset, reset PRAM, no change at all. (After reset the SMC he worked shortly, but after about 15 minutes even error.)

    FN + F1 - F9 does not either.

    Also, I checked my console to find errors, that's what I get when I press F1/F2.

    ATTENTION: assert (-1! = internal) failed in the function-[DeviceGammaContext isInternal]: 2096 in file /Library/Caches/com.apple.xbs/Sources/AmbientDisplay/AmbientDisplay-58/Sources/ DeviceGammaContext.m

    This error no longer appears.

    I have to say, I got my Logicboard exchanged 1 week ago by an Apple Technician due to the graphic problem common with the older MBP.

    Can it be a coincidence? It has something to do with the keys without work?

    Thanks in advance for your help

    Chyllie

    EDIT: There was no liquid spilled on the keyboard, or something similar, also when I plug in an external keyboard (non-apple) the right shift is working on it and also the buttons Play/Forward.

    It was a bad connection to the logicboard, for all who have the same problem!

  • HP 250 G2 KEYBOARD FN KEYS NOT WORKING NOT

    Hello, I recently bought a laptop HP 250 G2 without OS (freedos)

    After you have installed windows 7 Home premium x 64 I went to the web page of the HP support and downloaded all the drivers, install them and everything seems to work without problems.

    The only problem is that the HP support page does not all the drivers for the keyboard and the result is that all the FN buttons are non-functional.

    In Device Manager the keyboard is displayed normally because Windows 7 automatically installs the drivers, but these aren't 100% compatible so that the FN keys would work.

    Please, it is very important to be mean use only FN keys so that I can change the brightness, sound level and tun works / stop wifi.

    Thanks in advance.

  • Some keys stop working after the update of the Sierra (only for a specific profile)

    After update to Sierra my keyboard worked well for a while.  But at random, U I O P J K L keys stopped working.

    The bug only shows 1 profile. If I create another profile new profile keyboard works very well.

    Anyone know what that sometimes caused that and with the fix is?

    Hello ExcelsiorPath,

    After reviewing your post, it seems that several keys do not work on a single profile. This looks like an option that may have been changed.  I recommend you to read this article, it may be able to help solve the problem.

    If the other keys do not work

    You may have accidentally set an option that changes your keyboard works.

    • Choose the Apple menu > System Preferences, click Accessibility, and then click keyboard. Make sure that slow keys is turned off. If slow keys is enabled, you will need to keep a key longer than usually before it is recognized.

    • Choose the Apple menu > System Preferences, click Accessibility, and then click mouse and Trackpad. Make sure that the mouse keys is turned off. If the mouse keys is enabled, pressing the keys in the numeric keypad moves the pointer instead of entering the numbers.

    • Choose the Apple menu > System Preferences, click keyboard, and then click input methods. Select "Show the menu in the menu bar." Open the menu entry, then make sure that the correct keyboard layout is selected.

      To display the keyboard layout, click keyboard, and then choose "See the viewers for emoji keyboard symbols in the menu bar."

  • How to restore my factory settings keyboard? (some keys not working only not on the new unit)

    I bought a HP dv6 - 6167cl last night the Club of Sam and I like the laptop, but for some reason, the right shift - (shift more long 'Break' and 'Shift' written on the key) does not work. I am trying to determine if it is a problem of driver or system configuration, or if I need to exchange the computer to another. It may even be a user error - is there some kind of thing to use the shift key? (function toggle or something)

    Try to back up your personal files and perform a recovery that would put the laptop to a factory State. Instructions can be found below
