Backlit keyboard has stopped working on Satellite P50-A-12Z

I bought my P50 A 12Z Satellite a year ago, and in recent weeks the backlit keyboard has stopped working.

I used to hold the FN + W to toggle the keyboard light, but now it no longer works and I have the message "chronometer" on the top right of the screen as you can see in this screenshot:

  • Dell bluetooth keyboard has stopped working

    I have a dell keyboard and mouse bluetooth.  The mouse works fine, but the keyboard has stopped working. Batteries are fine. Cannot 'discover' the keyboard because I don't seem to have any device options 'bluetooth' in my control panel devices. Any ideas?

    Contact Dell or just buy a new keyboard.  Wired are really not expensive - I bought one for $9 that works very well.

    Good luck.

    Hello.
    For some reason, the keyboard on my laptop Satellite 1000 series has stopped working (I think someone was able to associate some liquid above...). Device displays Manager ' easy internet keyboard "and"logitech HID-compliant keyboard"(which refers to a USB keyboard I was forced to buy).
    No luck, anyone know what is happening and how I can get my keyboard to work again? Maybe something to do with the reinstallation of the drivers?

    Hi Adam

    If somebody spilled a little liquid to hardware malfunction and I guess that the keyboard is default now. Try to contact the Service partner and pick up some information how the new costs of keyboard. You can also a Google a little bit around and find that keyboard correspond to your model of laptop.

    In my opinion you can exchange only.

  • Numbers of wired keyboard has stopped working

    I have a keyboard attached to a wired Macbook Pro Apple. The keyboard worked fine for a year apart from the occasional glitch when it stops working, I add an extension of cable and it starts working again.  However, all of a sudden the numbers on the keyboard at the top of the keyboard have stopped working (but - and = work). the keyboard on the right continue stop work very well.  I think the function keys work always.  Someone at - it ideas?  It's driving me crazy! Tried to restart and don't Scream - no luck so far.

    Hello Lloyd C from the United Kingdom.

    If I understand you right, the numbers on the wired Apple keyboard that you have connected to your MacBook Pro stopped working. We know that it's never ideal to have a device that does not work as expected, we are happy to help you get the keyboard to work again.

    The first thing I would recommend, first and foremost, is to update your Mac if there are updates available for the version of Mac OS X, you're running. Follow the steps in the article to support below if you are not familiar with how to update. For the purposes of troubleshooting, whenever you test your keyboard after you follow the steps that we provide, make sure that it is while the keyboard is connected directly to the USB port built-in on your MacBook and not connected to a USB hub. In addition, disconnect all other devices you have plugged into your Mac, besides than the charging cable under test.

    Update the software on your Mac

    If the problem persists after the update, the next step would be to reset the system management controller (SMC). The MSC is a part inside your MacBook, who helps run various physical parts of your computer, and resetting can sometimes help the problems associated with the keyboard and USB functions. The support article below contains the steps on how to reset the SMC.

    Reset the management system (SCM) controller on your Mac.

    Test the keyboard after that the MSC has been reset. If the problem persists, follow the steps in the "Steps to a USB keyboard" section in the following article:

    If your USB keyboard or wireless does not work

    Remember that it's always a possibility that the issue could be with the keyboard itself. If you continue to have problems with certain keys, try to connect the keyboard to a different Mac, if you manage to and see if you experience the same problems.

    Thank you for using communities of Apple Support.

    Take care!

  • Display has stopped working on Satellite A300

    Hi guys,.

    I have satellite a300 PSAg4a - 02500 m laptop. All of a sudden the display has stopped working on the laptop. I tried to plug in an external display, but it does not work also.

    I can't even see the bios screen not. Laptops normally, I hear no beeps during startup, just the fact that there is no display.

    This laptop has a M86 ATI graphics card 512 MB. Its out of warranty.

    All had a similar experience. Is it possible to know what could be the problem.

    Any suggestions would be helpful.

    Thank you

    Hey Tama

    I'm afraid there is a problem of serious material with your laptop from m.
    I like the graphics card problem.
    Usually if the internal screen would be defective, you should see all the external display. This is why I think you GPU is affected.

  • TosIPCSrv.exe has stopped working on Satellite A300

    When I start my computer... (Vista) I have Toshiba Satellite A300
    I get a warning said: TosIPCSrv.exe has stopped working

    What it means? How should I do?

    Seems the TosIPCSrv.exe belongs to the Toshiba S.M.A.R.T. Log Service.
    This can be found in:

    C:\Program files\toshiba\smartlogservice\tosipcsrv.exe.

    I'm not very well what is this process, but you could it enable or disable it in m
    MSCONFIG (type this in the window RUN) and check the startup and Services tabs.
    You need to find tosipcsrv.exe

  • All USB keyboard has stopped working

    Hello

    All USB keyboards have stopped working on my installation of windows 7. They work fine in the BIOS or on my Ubuntu installation. When I plug a keyboard, it still gives an error code 29 (drivers not found). I tried using two keyboards: a Logitech Gaming Keyboard G105 and a fairly generic wireless keyboard (a dongle to connect to the computer).

    I tried to uninstall it from the Device Manager and plug or restarted again, but the result is the same. Windows Update cannot find driver updates, and a system repair disc doesn't detect any problems. I temporarily created a fresh install of windows 7, which recognizes the keyboards very well. There is no driver available manufacturer (attempt to all keyboards are supposed to use the base drivers), and the keyboard Logitech gaming software does not see that it is there. 'Control Panel-> devices and printers' keyboards of lists of names, but the shows not even the stuff of work that is just under the Device Manager and the problem-solving the tent and is unable to find the drivers again. Try to select the driver HID keyboard in the Device Manager just in fact give the code 10 error (device does not start) instead.
    Nothing I've tried has gotten me anywhere. I would rather not re-install Windows 7, like all the time and effort to get my system how do I like it took me forever, but I can't see how I solve this problem. Any help would be appreciated.
    Thank you
    Zoden

    There is a good chance a "repair" install will fix the problem as a "repair" install should re-create any missing or corrupt driver installation file.

    I don't see anything definitive where observer records but can provide you with the following file, which can provide more specific information:

  • Satellite L650-170 - keyboard has stopped working

    Hello.

    The problem is that my laptop keyboard has suddenly stopped working. It does not at all.
    Although it responds until Windows loads up, which means that it is a software failure. External USB keyboard works too.
    Someone has any idea how to solve this problem?

    Hello

    This means that in Windows the keyboard doesn t work?

    In this case, I would try a system restore to an earlier point. Maybe this can help get rid you of this problem.

  • Satellite P850-12Z - several keys on the keyboard has stopped working

    Hi all

    It all started a month ago or not.
    My keyboard of laptop (a Toshiba Satellite P850-12Z) began to fail. First was the BACKSPACE key, but subsequently was the numeric keypad 3 key and the Enter key.

    They start working if I hit them several times about 10 seconds or more. You can imagine it's very annoying and frustrating.

    Do I need a new keyboard? For more information, the keyboard fails also under linux.

    In case I need a new keyboard I think that Toshiba was of very poor quality, and I will never buy a Toshiba again.

    My last laptop was from another brand, and the keyboard never lack in 5 years.

    > Do I need a new keyboard?

    Probably yes.
    Connect the external keyboard and check if its not working properly.

    If the external USB keyboard works, so is there a problem with the keyboard controller but with internal keyboard.

  • Touch pad/keyboard has stopped working.

    Hi there. im hoping someone can help me with a question im having my laptop. for some reason any my touchpad and keyboard stop working. I tried reintalling windows to correct the problem that it does for one day and then the same thing happens again. When I checked in Device Manager and clicked on the PS/2 mouse, he said that there is an error code 10. If I uninstall ps/2 and reboot the laptop this solves the problem for a while, and then it happens again. My OS is windows 7, I think it has been upgraded to windows vista (I recently bought this 2nd hand computer laptop) so im not 100% sure on that. the date of the driver for the ps/2 compatible mouse is 21/06/2006. I tried to look on the Web site for a more updated keyboard to update driver, but I can't seem to find a. She seems to have all other drivers dismantled for the keyboard driver.

    any help would be greatly appreciated
    concerning
    Johnny.

    Hello

    Test the laptop using the external USB keyboard.

    Its certainly not related issue the keyboard driver keyboard driver is part of the Microsoft System and cannot be installed separately.

  • I deleted the driver for the mouse and the mouse and the keyboard has stopped working.

    I had installed an updated driver mouse and mouse keep locking up. The Windows troubleshooting information indicates that I have to erase the disc from the mouse, and then reinstall the new mouse driver. When I deleted the mouse driver, the mouse and the keyboard no longer works.

    The computer is running Windows XP with Service Pack 3.

    The computer is one that I built several years ago.

    I tried the things:

    1. I tried the ALT, left SHIFT + Number Lock which is indicated as mouse keyboard operation who has worked in the past.

    Well it does not either from the keyboard is dead.

    2. I tried PS2 Mouse and a keyboard.

    3. I tried a keyboard and a USB mouse. The system shows new hardware found and he wonder then click NEXT to load the driver. No mouse, no keyboard, so no click.

    4. I can't get into the bios, because I can't hit keys to vector in the bios during startup.

    5. I tried to load the Windows XP disk, but the startup routine ask me to hit any key to boot from the CD.

    I have no mouse or keyboard control and therefore cannot respond to any action required by the system.

    Does anyone know a way to solve this problem?

    Solution of my wife - buy a new computer.

    Have a better solution for this problem?

    Thank you

    Bill

    Always try a PS/2 keyboard.  Maybe your PC is not able to access the BIOS, because the keyboard is USB.

    What make / model of the keyboard / mouse "kit"?

  • The audio controls on the top of the keyboard has stopped working.

    At the top of the keyboard controls that control the volume mute and sound stopped working.  The machine is a Pavilion dv7 Windows 7.  Sound keys are light up and when the machine starts and stops the symbol for the 'secret' change to red.  After booting the machine it turns on but does not work.  I was wondering if these controls are selectable by software and I stop them inadvertently.

    Hello

    Try a Hard Reset as follows.

    Shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery, connect the power adapter and start Notepad.
