Alt key does not work

Hello

I have a problem on my laptop. My laptop is HP pavilion g4-1357tx, with Windows 7 64 bit, already implemented to date with the new BIOS provided in the HP website.

I've updated my laptop Windows 7 32 bit to 64 bit 2 weeks ago. Since then, I can't use alt keys, both left and right. Some information on the internet, said there could be some dust under the buttons and I tried to clean it up, but the problem is still happening.

Can someone help me with this?

Thank you.

Please perform the steps to fix the problem and let me know how it goes below:

Step 01. Click the Start button and select Control Panel

Step 02. Open Device Manager and expand the keyboard in the list

Step 03. Right-click on PS/2 Standard Keyboard and click on uninstall

Note: This driver will settle again automatically on your laptop

Step 04. Please turn off the laptop

Step 05. Disconnect the power/AC adapter and also remove the battery too

Step 06. Press and hold the power button of the laptop for a minute

Step 07. Now re - insert the battery back in and plug again the power supply/adapter

Step 08. Start Notepad and keep pressing the F10 key during startup to access the BIOS

Step 09. Once you get the BIOS, please press F9 or [model] F5 key to load the default Installer for BIOS

Step 10. Use the arrow keys to say 'YES' and press enter

Step 11. Now press ESC/ESC. Save Changes and Exit - Yes

Step 12. Now, please wait until the unit load the Windows operating system

  • The shortcut Ctrl + Alt + C does not work in InDesign CS6.

    The shortcut Ctrl + Alt + C does not work in InDesign CS6. I don't have an ATI video card, the shortcut key is not related to the center of catalyst.

    I have a Nvidia GeForce GTX 980 video card and I reinstalled Windows 7 x 64 three weeks ago. Since then, the shortcut Ctrl + Alt + C does not work.

    I tried to reinstall the program. I tried to clean the preferences file. Yet, nothing is done. I googled if there other programs that could take the shortcut for themselves. The InDesign menu says that the Ctrl + Alt + C is linked to the action "was". But nothing happens.

    If you have any suggestions on what do I do to fix this, please help.

    P.S.: before the reinstall, everything works great.

    MB: ASUS P8Z77-V Deluxe

    CPU: Intel® Core™ i7-3770 3.4 GHz

    GPU: NVIDIA GeForce GTX 980

    But no. I think I thought it somehow.

    I just reinstalled the CS6 InDesign from scratch, as stated in the above post. Just as new as possible. And he was always in trouble. Then I disabled the two automatic startup items:

    Broadcom 802.11 Network adapter wireless Tray Applet

    and

    Driver Logitech SetPoint.

    After that, everything is back to normal.

    I guess that one of them had caught the hotkey without mentioning, so that should be the fault. I don't think that other programs (with the exception of Adobe) have the same key as InDesign links.

    P.S.: Just restarted each disabled program and it's Broadcom 802.11 Network adapter Wireless Network Tray Applet that shows problems with the keys.

    So, thanks for trying to help me solve my problem.

    If anyone else has trouble with the keys and they have this specific bin running applet, better turn it off to be sure. In the Windows Task Manager, it is called C:\WINDOWS\SYSTEM32\WLTRAY. EXE.

    Hello

    Install the VAP (value added package) and reboot the laptop.

    Then install the Support Flash Card utility and reboot once more.
    Then test the Fn keys.

    The buttons are controlled by Flash cards, so you should be able to use the buttons after a new installation of this app.

    the FN key is not working and when you start get the recovery of the thotkey failed

    What function of the FN key doesn't work?
    If the switch show FN + F5 n t work buttons you need to install utility for display devices access keys. If the wireless shortcut key does not work, you need to install Wireless hotkey.
    As you can see, different applications and drivers are required to use different Fn keys.

    But common modules must be installed always, because this driver is important for every application from Toshiba. Also, be sure to reinstall the utilities.

  • The internal keyboard BACKSPACE key does not work

    I have a laptop Toshiba Satellite and the BACKSPACE key does not work.

    He will start work the rare opportunity, but then it just stops working again.
    This happens on everything, including word and internet ect.

    It has been like that for a few weeks now and I turned the laptop and turn off many times.
    Is there a way to fix it myself or I send for repair?

    Please, * don't * tell me:
    Get an external keyboard
    Try it turn on and off
    Just highlight the words and use the delete key - it's annoying to have to do this all the time
    Type carefully and do not make so many mistakes

    Thank you!

    > Please, don't tell me not to:
    > Get an external keyboard

    And why shouldn't t someone recommends you to check the functionality using the external keyboard?

    It s recommended to connect an external keyboard to verify how the BACKSPACE key would work using 2nd external keyboard. In case the back might work properly using USB keyboard, the question is very clear; in such cases its main shortcomings. The key cannot be replaced or changed or fixed. In this case, need to replace the entire keyboard!

    In case the BACKSPACE key does not even using the external keyboard, then this would mean that the internal keyboard controller is faulty and in this case only the replacement motherboard would be useful.

    But to be honest, I think that its simple keyboard failure and a replacement would solve this.
