    Thank you

    Hello

    I don't think that a single Win 8.1 update would affect single keyboard buttons.
    It doesn't make any since to me
    That's why I m not quite sure if it s really a software problem.

    You have an external USB keyboard? You can test it in your laptop?
    The fact is that if this USB keyboard would work properly, software is not the problem but the internal keyboard could be the troublemaker.

    I think you should test this before you try to reinstall the system

    Hello

    This could be a hardware problem, but it is always worth trying the following.

    Open windows control panel, open Device Manager, expand keyboards, right-click on the "Standard PS/2 Keyboard" entry and select uninstall.

    Shut down the laptop - it by holding down the button SHIFT left click Shutdown to temporarily prevent a hybrid boot.

    Then disconnect the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

  • HP Pavilion Notebook - 15-ab04: some keys on the keyboard does not

    Hello

    Recently I'm impossible to insert the exclamation mark (SHIFT + 1) on all programs. I know there is no problem with keys like shift key works and the number 1 button also works. But when I press these two keys in combination that I get nothing (just tried to put an exclamation mark here without result).

    This problem happened with HP Win 10 laptop my father as well. Suddenly the majority (nearly half of his keys) has stopped working and it uses an external keyboard for 2 months (once more tried to put an exclamation mark here without result).

    Really disappointed because it clearly seems to be a problem of HP after what is happening to my and my dad HP laptop computers only.

    Can someone shed light on this you problem. Thank you.

    Good I manaeged to find the problem, I got an AHK script interefered with that somehow. So I removed it and it works.

    Hello

    Try Firefox Safe mode to see if the problem goes away. Safe mode is a troubleshooting mode, which disables most of the modules.

    (If you use it, switch to the default theme).

    • Under Windows, you can open Firefox 4.0 + in Safe Mode holding the key SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac, you can open Firefox 4.0 + in Safe Mode holding the key option key when starting Firefox.
    • Under Linux, you can open Firefox 4.0 + with leaving Firefox then go to your Terminal and running Safe Mode: firefox-safe-mode (you may need to specify the installation path of Firefox for example/usr/lib/firefox)
    • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. It might help others who have the same problem.

    I hope this helps!

  • T410 doesn't start, white screen and the keyboard does not power on.

    Hi, my laptop Lenovo T410 does not start. I hit the power button and looks like it is about to start. The thinklight flashes on as normal, the cd drive is checked, the caps lock on, then nothing/button blinks. No display and the keyboard does not respond. Power led lights up; If I leave it awhile the fan turns on. Can I stop the machine using the power button, but the problem remains the next time I turn it on.

    I tried to remove power and battery, power 10 button time then with the power to 30 seconds, before replacing the power supply and the battery but nothing happens. I tried to use a different keyboard. I tried to plug in an external monitor. No change.

    This problem appeared after I left it on overnight. I have the feeling that it entered into hybernation mode, perhaps, and that it disturbed some important functions which he could not complete. Not sure if. Any help gratefully received.

    Thank you very much

    Pete

    It's the original configuration of your laptop:

    ThinkPad T410 2522BF1
    i5 - 520 M (2.4 GHz), 4 GB RAM, 160 GB 7200 RPM HD, 14.1 in. LCD 1280 x 800, Intel 5700MHD, DVD, Intel 802.11agn Wireless Modem, 1 Gb Ethernet, UltraNav smart, secure, camera, 6 c Li-ion, Win7 Pro 32

    I firstly the LCD cable or secondary LED could be damaged, but if you don't see anything on an external monitor I tend to think it's a motherboard problem.

    Last thing you could try putting running a Live Distro Linux from a CD/DVD or USB drive, using Ubuntu or Linux Mint, for example.

  • Problems with the keyboard does not

    I am on windows 7 and for a week, my keyboard does not work. some of the keys do not work. p, return, tab key, and a few others do not work. My on-screen keyboard works fine - except for the question mark-. I tried the drivers, and the computer says that it has the best drivers so no need to update. I don't know where it came from, but then, after an update of windows, my keyboard is back to normal. It worked fine for three days and then, once again, he screw up. It's always the same keys that don't work, so I don't think that my keyboard is worn. my computer is only a year. It's a computer laptop sony vaio. whenever I press the p key, for example, the Start button - a physics - flashes. same thing for the other buttons. When I press the return key, the Start button flashes.

    in the bios, the keys do not work either.

    can anyone help

    Get a cheap USB keyboard and see if it works.  You can buy those cheap for $10 or less.  The fact that the keyboard does not work in the BIOS means is not a Windows problem.

    Good luck.

  • Key on the keyboard does not work in firefox box when you type in the web site, but it works everywhere else?

    Key on the keyboard does not work in firefox box when you type in the web site, but it works everywhere else?

    Try Firefox SafeMode to see how it works there.

    A way of solving problems, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open the mode without failure of Firefox 4.0 + by pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
    • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

    Do not choose anything at the moment, just use 'continue in safe mode.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

    If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.

    Thanks in advance.

    Hello

    I guess you checked if the Tablet has been properly connected to the docking keyboard.

    Have you tried to unplug and plug the docking again?
    Note: there is a latch on the left you have to move and in order to remove the tablet.

    Perhaps there is a connection problem.

  • Satellite A300D-126 the keyboard does not work

    I reinstalled the driver but it still does not. What could be the problem? Help please. Thank you

    Hello

    What s wrong exactly?
    You have reinstalled the drivers?
    What drivers do you mean?

    The keyboard driver is part of the Windows operating system and it cannot be reinstalled separately.

    If your keyboard doesn't work properly then either the software doesn't run as it should, or the material (keyboard) is defective.

    You could try reinstalling the operating system using the Toshiba HDD recovery to check whether the problem is related to the software.
    If the keyboard does not work after this procedure, then a hardware problem might be possible.
