Lenovo G550 Keyboard not Working.... Can't log in to the system...

Hi, I am using Lenovo G550 Model. Yesterday, I started facing this problem. When I tried to login, none of the keys worked. When I pressed Backspace, it started typing something. I tried to use on screen keyboard, which did not help either. Same problem persists with on screen keyboard as well. I, even, tried using an USB external keyboard & the same problem is there too. Kindly help me!!!

hi Avikiru,
Welcome to Lenovo Community Forums!
Can you try,
   Remove the AC and the Battery
       Hold the Power Button down for at least 15 sec.
              Reconnect just the AC and see if that'll work
If not You can contact a Lenovo Support Team or a Local Technician to have the Keyboard connection checked.

  • Fingerprin​t reader on Lenovo KUF0452 keyboard not working with Lenovo X1

    Hi, I have a Lenovo KUF0452 keyboard with built-in fingerprint reader. Up until two weeks ago I had a two year old X1 Carbon laptop which co-existed happily with the keyboard - I could unlock Windows with a swipe of the keyboard's fingerprint reader. I've now replaced the old X1 with a brand new X1 Carbon and can no longer unlock Windows using the keyboard's fingerprint reader - I just get this error on the Windows 8.1 lock screen: "A match for the fingerprint was not found in the fingerprint database." I have the latest Lenovo Fingerprint Manager Pro installed and have used it to enroll a couple of fingerprints for the X1's fingerprint scanner, but when I try to use it to enroll fingerprints for the keyboard's scanner the app's progress bar doesn't move off 0%, so I assume the app isn't accepting the keyboard's fingerprint scanner as a valid input. The X1 is docked, with the lid shut, so I have no easy access to the laptop's fingerprint scanner which is why I want to use the keyboard's fingerprint scanner to unlock Windows. How can I get the keyboard's fingerprint scanner to work with my X1? Kind regards,

  • Fingerprint reader on Lenovo KUF0452 keyboard not working with Lenovo X240

    Hi,
    I have a Lenovo KUF0452 keyboard with built-in fingerprint reader. Up until a month ago I had a Lenovo X220 laptop which co-existed happily with the keyboard - I could unlock Windows with a swipe of the keyboard's fingerprint reader.
    I've now replaced the X220 with an X240 and can no longer unlock Windows using the keyboard's fingerprint reader - I just get this error on the Windows lock screen:
    A match for the fingerprint was not found in the fingerprint database.
    I have Lenovo Fingerprint Manager Pro v8.01.35(x64) installed and have used it to enroll a couple of fingerprints for the X240's fingerprint scanner, but when I try to use it to enroll fingerprints for the keyboard's scanner the app's progress bar doesn't move off 0%, so I assume the app isn't accepting the keyboard's fingerprint scanner as a valid input.
    The X240 is docked, with the lid shut, so I have no easy access to the laptop's fingerprint scanner which is why I want to use the keyboard's fingerprint scanner to unlock Windows.
    How can I get the keyboard's fingerprint scanner to work with my X240?

    hi jenniby,
    Welcome to Lenovo Community Forums!
    I believe it is the Lenovo B570 you're saying, 
    Try doing a power drain,
        Remove AC adapter and Battery, then hold down the power button for at least 15 sec. this will drain off the power from the MOBO.
    Reconnect everything and see if that works,
    Also try using an external Keyboard to test out the Windows.
    If that did not work I suggest Calling Lenovo Technical support for Hardware Concern.

  • Lenovo E540 keyboard not working

    Hi All, I have a E540 laptop which is having a feww issues with the keyboard. The numbers 12347890 do not work along the top and 3 on the numbers pad doesn't work I have tried installing newest drivers uninstalling the keyboard from device managemetn a system restore changed a key in regedit also. Im really struggling for ideas but seems like it is an issue with the software and not the hardware? any help is greatly appreaciated Cheers Alan  

    The sound drivers for Thinkpad Edge E540 might have been damaged or corrupted, so sound is not working. You need to select 'Audio' under 'Component' and choose your operating system under 'Operating system' from below link. Download and install audio drivers and check now if sound is working.

  • Inactive memory. it's not working properly, how do i tweak the system to fix it?

    hi.
    my system has 24 gigabytes of ram. I use After effects and photoshop and illustrator... all day, every day, going back over 10 years.
    when I run a particularly big project in AE, one that uses big fies, or a lot of files, the inactive ram very quickly balloons out of control.
    prime example: I am rendering right now, it takes about 12 minutes to render the comp, in 12 minutes the system will go from zero megabytes of inactive ram, to 17 gigabytes, leaving me with no ram for the system, causing in some severe cases: actual hard crashes. I continually have to monitor and run a "purge" command in the terminal in order to cut that out.
    the documentation and general discourse I've read agrees that inactive memory is the same thing as free memory, in that it is available for applications with need to use it. But, it contains potentially useful data that was recently used, and the system would rather give you the free stuff before giving you the inactive stuff.
    here's the problem:
    Aftereffects uses this memory, and then frees it. it's full of gibberish, it gets used quickly, and released quickly, and pooled into inactive memory. At this point it should be availible for other apps to use, and it isn't. it is treated as if it is in use. The system can't use it, aftereffects can't use it, no other app can get this ram allocated to it. Inactive memory, becomes terminal memory, memory that is not available for use by the system.
    I know there has to be a system default or a setting in the terminal, I can set to make it trigger happy and automatically free up this useless memory.
    what is it?

    Inactive memory is the operating system cache.
    This cache may contains data which has not been written to disk (called dirty pages).  This is because Mac OS X defers flushing dirty cache data to disk to cut down on contantly starting up idle disks, consuming power, draining laptop batteries, and adding extra wear to solid state disks which have a limited number of writes.
    When Mac OS X has lots of inactive memory and the system starts to slow down, this is because now the OS is being forced to write the dirty cached pages to disk before it can give those pages to another applications, or to reuse those pages with the same applciation.
    After effects and photoshop and illustrator are very memory intensive apps.
    ...causing in some severe cases: actual hard crashes.
    That is either a hardware problem, or an operating system bug.  You should file a Bug report including your crash dumps to Apple.

    Aftereffects uses this memory, and then frees it. it's full of gibberish, it gets used quickly, and released quickly, and pooled into inactive memory. At this point it should be availible for other apps to use, and it isn't. it is treated as if it is in use. The system can't use it, aftereffects can't use it, no other app can get this ram allocated to it. Inactive memory, becomes terminal memory, memory that is not available for use by the system.
    The inactive memory may still be part of the After Effects address space, just not in the current process working set.  That is to say, ever so often the operating system will mark pages inactive and see if the process references them again.  If it does, they are put back in the process' working set (quickly because they are still in RAM and it just requies updating some process tables), otherwise they sit in inactive memory.  If they are really part of After Effects address space, then chances are the data in those pages is dirty, and before they can be given to another process the pages have to be written to the /var/vm/swapfile(s).
    If After Effects generated this inactive memory by reading files (and only reading), then those pages are clean (not dirty), and can easily be moved to free pages and given to a process as there is no need to write them  back to disk, as the disk has the same values as what is cached.
    If After Effects generated this inactive memory by writing data to files, then the pages are dirty and are waiting to be written to disk.  Unless the file has been deleted after the write (such as a scratch file), then the operating system must write the data to disk before it can reuse the inactive pages.  It does not matter if later the file will be deleted, the operating system does not know that, so it cannot give those pages to another process until they have been written to disk.  The except being if and only if, a process is also accessing (reading or writing) that file, then cache starts to pay for itself.
    The operating system does not refuse to give inactive memory to other processes, it just has responsibilities to make sure dirty pages are properly moved to stable storage before the pages are reused.  And generally speaking stable storage is slow.  Orders of magnitude slower.
    If you want  to control when you the operating system cleans dirty inactive memory, then you may continue to run the 'purge' command.  As long as you are not running it non-stop, and especially if you are using a laptop or solid state disk.
    Then again, getting more RAM will allow the operating system to dirty up more RAM before it needs to start flushing to disk.  And replacing your disks with solid state disks (SSDs) will allow the operating system to flush dirty pages much faster when it needs to start cleaning the inactive memory.

  • Satellite L300 - 'W' and 'F' Keys not working - can't log

    Hi,
    I have a Toshiba Satellite L300.
    My 'F' and 'w' keys arent working, and because I have a Built-in HDD user password of which contains those letters, I can not start up my computer.
    I had a 'startup' problem a couple of months back, and what I had to do was restore my laptop to a previous date. I did this through Boot management during startup. The only thing is I cant remember how to do it now.
    I cant find any restoration disks that may have come with my laptop- so the only way I can do it is through boot management.
    So, how do you do a system restore? or is there another way of fixing this problem?.
    Please help!! :)

    Hello
    If W and F key dont work I would recommend replacing the keyboard or use an external one. In my opinion its the best choice because you also need the keys for typing letters or emails
    You can get a new keyboard from an authorized service provider in your country.
    > I cant find any restoration disks that may have come with my laptop
    I think you should read the user manual because you have to create this disk yourself ;)

  • My EE app not working & can't log in to account

    Dear David M, would it be possible to re-set my account as well. I ported my number over from Giffgaff yesterday and can't use my online account or phone app. Same problem as above. Thank you, Markus 

    @simonsl8er
    If you have setup a My EE account and were using prior to changing your number, the online service does not update this number for you and it will not provide you access.
    Please send us your new number in a private message along with your full name, the email address you registered your account with, we can then ask a few additional security questions in order to check this out further for you.
    Thanks,

  • Keys on keyboard not working.

    Greetings all, we are having trouble with several keys on our keyboard not working. First it started with the ENTER (non numpad) key not working, shortly followed by the TAB and CAPS LOCK key.
    Any clues as to what caused this and how to fix it? It's the keyboard that came with the iMac. I've already tried unplugging it and plugging it back in.
    Thanks.

    I am having a similar problem, although in my case these keys do not work in conjunction with the "W" key. For example, command-W only works with the right-hand command key, and to turn "w" into "W" I must use the shift key on the right-hand side as well. This machine is less than a week old, and I have Adobe CS2 installed. Have you found any soulutions?

  • My MacBook Pro keyboard not working correctly after Win7 bootcamp installation. In OSx boot it keep Win keyboard. How can I have Mac keyboard in OS boot and Win keyboard in Win boot?

    My MacBook Pro keyboard not working correctly after Win7 bootcamp installation.
    Installation went well but when I boot either with OSx or Win it always keeps Windows keyboard.
    How can I have Mac keyboard in OS boot and Win keyboard in Win boot?

    Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
    I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
    Thanks in advance!

  • Bottom row of the keyboard is not working in a vertical orientation on the iPhone 3Gs. the "slide to unlock" and all keys on the calculator on both orientation works fine. I can use the keyboard on horizontal orientation.

    Bottom row of the keyboard is not working in a vertical orientation on the iPhone 3Gs. the "slide to unlock" and all keys on the calculator on both orientation works fine. I can use the keyboard on horizontal orientation. The tabs on bottom of all apps also work fine.
    I have already tried holding down the power button and home button for 10 seconds, but no difference.

    I've had this problem on and off for the last few weeks (around, but not directly related, to upgrade to 6.1...can't remember if was before or after)....I'm very convinced it's a software problem (as there have been times when the bottom row works perfectly, without any need to "press" differently or anything).
    However, it seems to be a rather resilient software issue, as a full restore does not consistently fix it, and it applies to more than just the keyboard; if I open a drawing app, there's definitely a row (about 4mm up from the edge of the screen closest to home button) where I cannot draw.
    It's happened 4 times now.  Originally it went away with a restore from backup, then worked for 2 more days.  The second and third times, it went away with a full restore (although I did two full restores in between those two restores that did nothing, so restore didn't consistently fix it)....and it seemed to return in the most random of circumstances. 
    I paid very close attention to what apps I was using the last time it was working so that I could spot which app, if any, might be causing the issue.  I deleted several apps, I stopped using the games and many other apps.   I only used three apps between it working fine and starting up as a problem again: mail, safari and messages.
    I was convinced it was mail, as it happened this morning when I picked up my phone off the bedside table to respond to a new email.  It was working when I went to bed.  I picked up the phone when it buzzed, hit the email app, hit reply and started to type....**** bottom row wasn't working again.
    However, tonight I did 2 things....one of them worked because it went back to normal (sorry, I don't know which as I was exasperated and trying a number of things). 
    The two things I did between a broken keyboard and a working keyboard were:
    1) adding a second keyboard (English(Canada)), changing to this keyboard, and changing back
    2) disabling Siri...and then turning it back on...and then disabling Siri's "Raise to Speak"
    In retrospect, I wonder if it actually was the "Raise to Speak" that was putting the phone into a weird state, and might explain why the phone would just "suddenly" start behaving strangely when I picked it up.  Of note, the "raise to speak" hasn't actually triggered Siri to come on in months anyway.
    Regardless, the keyboard is back to normal now...and I'm just going to leave "Raise to Speak" off.  I've put the keyboard back to just "English" with no alternates and Siri remains on otherwise without issue.

  • Why is Emoji Keyboard not working with iOS7....??? Is there any setting which I am missing? Can anyone help

    Why is Emoji Keyboard not working with iOS7....??? Is there any setting which I am missing? Can anyone help

    Yes. you should keep your media in iTunes, and indeed you should also keep a backup of your library as well. if you have the device set up for manual management then the content would remain on it when deleted from the library, but you would have no way to restore the device if there was a problem.

    Should I check the memory cards themselves? Reseat them?
    Yes.
    Memtest X or Rember to test the RAM.
    Reseat is also good.
    The iPhone 4 doesn't like USB 1.1 much.
    after the update the computer was working well, except for this freeze when ever I connect iPhone.
    I'd try USB 2.0 PCI. That's how I connect my iPhone 4s, and have connected all iPhones and iPods, to my G4.
    Never an issue.
    Can't say the same for USB 1.1.......
    The above (previous post) linked PCI card is cheap enough.
    Want cheaper, try this:
    http://www.amazon.com/Protronix®-5-Port-Controller-Card-Chipset/dp/B005JE2U82/re f=sr_1_2?ie=UTF8&qid=1337472141&sr=8-2
    The NEC chipset is the desired chipset, regardless of what OS the maker says is compatible.
    OS X has native NEC chipset USB support.

    Hi ,
    Do you remember if you  have installed some software prior to this issue?
    Delete programs you never use.
    If the issue reoccurs in Clean Boot, but works fine in Safe Mode, the cause may be the disabled hardware drivers. You may narrow down the
    causes in Device Clean Boot.
    Device Clean Boot
    =================
    1. Click Start, type "devmgmt.msc" (without quotation marks) in the Search bar and press Enter.
    2. Expand "Sound, video and game controllers".
    3. Right click on your sound card and then click "Properties.
    4. In the dropdown menu of Device Usage, please choose "Do not use this device (disable)" and click OK.
    5. Please use the same method to disable other dubious hardware such as: internal modem, network card and CD-R drive. Please note some devices
    such as video adapter are not available to be disabled.

  • Number 4 on my wireless keyboard is not working can someone please help

    number 4 on my wireless keyboard is not working can someone please help

    You do know with absolute certainty he, that the mic does not work at all? Have you tried recording a video with sound to test to make sure that the microphone isn't working?
    if you have tried recording a video with sound and that did not work, have you tried any troubleshooting steps at all? Have you looked to see if there is any debris covering the mic? Or do you have a cover that could be interfering with the microphone?
    you can start with a reset of the iPad if you haven't done anything else. Hold down on the sleep and home buttons at the same time, for about 10 seconds, until the Apple logo appears on the screen. When you see the Apple logo on the screen, you can let go of the buttons and let the iPad start up. Try the microphone after the iPad starts up again.
    You could try restoring the iPad to factory settings and see if that recovers the microphone for you.
    Use iTunes to restore your iOS device to factory settings - Apple Support
    It is also possible that you could have a hardware issue which you will not be able to resolve on your own. If you cannot find any other way to get the microphone to work you may end up having to take it to an Apple store and let an Apple genius evaluate the device.

  • Keyboard not working even when trying to go to BIOS

    Hi,
    I have IBM Thinkpad R60 9458 A13 laptop having Windows 7 ,today its keyboard is not working but in Windows its function keys like brightness or sound is responding without pressing Fn key.
    And no other letter or numeric key is responding.
    I tried to boot the laptop and trying to press Thinkvantage button, its not responding.
    I then inserted Windows 7 OS DVD and when prompt comes to press any key ..i tried all key but no help.
    I then clicked on Compatibility option to have keyboard on screen which is working fine.
    Pls advise what would have gone wrong
    Regards
    Sandeep

    Hi Sandeep,
    Welcome to Lenovo Community Forums!
    I’m sorry to hear that a few keys in the keypad of your Lenovo ThinkPad R60 is not working properly.
    Check if the keys are working in different applications. Some keys such as the function keys F1 through F12 will not work with every program. An easy way to test this is to open notepad or other word processing program and trying the key. Try getting into safe mode and see if the keys work. Remove the key from the keyboard and clean it. In some situations dirt, hair, dust, etc. can obstruct keys causing them not to work.
    Please try to get into BIOS mode and see if the keyboard is working there. Tap F1 key while system shows the Lenovo logo to get into BIOS.
    1. If you are able to use the keyboard in BIOS, it could be a software issue. I would recommend in that case to do a System Restore which will revert the settings in your system to a previous time.
    2. If keyboard doesn’t respond in BIOS as well, I strongly suggest you to contact our technical support for assistance.
    Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.

    Mithun.
