PS/2 keyboard works everywhere, EXCEPT through the windows

So, here's the problem.

My keyboard PS/2 BIOS order works, options boot F8, etc.  When the computer starts Windows, the PS/2 mouse works.  As soon as I hit a key on the keyboard, the mouse no longer works, and the keyboard does not work in Windows at all (without asterisk shows in the field password.)  This has only recently begun to arrive, and it's a clean install of Windows.  I haven't added new devices.

I tried Safe Mode, and the same thing happens.

I tried several keyboards PS/2, and none work.  I tried the keyboards on other machines.  Other machines do not have this problem.

I tried a USB keyboard, and it works very well.

I tried a live boot CD Linux with the PS/2 keyboard, and it doesn't have this problem.  I started in Linux two hours ago and after typing randomly on the keyboard during this period (every few minutes) everything still works well.  This leads me to believe that this is NOT a hardware problem.

Help, please.

Hello

  1. What is the number and the model of the keyboard?
  2. The keyboard is not detected in Device Manager?

If PS/2 keyboard works fine BIOS after Windows starts, I think it might have a driver that failed to load. I would suggest trying the following steps and check if it helps.

Method 1: make sure your PC is up to date

Make sure that updates are installed on your PC, including optional updates. For more information about installing updates for your PC, see Windows Update: frequently asked questions.

Now check if the keyboard works, if the problem persists, try Method 2.

Method 2:

If an adapter (PS/2 to USB or PS/2 to AT) is used, check that it is the adapter supplied with the keyboard or that the keyboard supports adapting to another port. For example, the Internet keyboard does not adapt to a USB port and a PS/2 to USB adapter will not work. It does not include an adapter.

Method 3:

Download and install the latest keyboard software

To download the latest drivers for the keyboard that you use, see the website of material.

    Just understand this point, it is CMD + "(le ~ clé)."  It's a really bad choice part of Adobe, and I can't understand how to change it.  It should be CMD + PgUp and PgDwn (it's darn near impossible to hit Command + SHIFT +' to save tab).

  • Updated to firefox9 and now when I use extension of tree style tab the screen goes black, with the exception of the "window of the tab" and the part of the screen behind him

    Update firefox9. Using tree style tab extension. Everything works fine, except that my screen goes black when in 'tab window', with the exception of the window of the tab and the part of the screen behind him. Once out of the tab section everything comes back fine, but it is rather annoying. Checked homepage for the extension and have the updated version, firefox add-on page - it also says that it is compatible. Any ideas on that?

     Am realizing pages will stay on as long as I don't move the mouse,but as soon as I do move it,black goes the screen.

  • Windows 7 click cycles through the windows environment

    Hello

    I just installed Windows 7 on my PC.  I have a Microsoft Wireless Optical Mouse 200 and I installed the software for the mouse on the Microsoft Web site.  I love the feature of the middle - clicking on a link in a browser to open this link in a new tab.  Unfortunately, as I installed Windows 7 on my PC, this feature does not work.  Middle clicking on my mouse over a link (or anywhere, in this case) cycles through all open windows.  What I mean by bike through the windows, it is if I have a window Explorer open behind my browser, clicking environment will present this window.  In the mouse software, I put the Middle click button to actually be a middle-click, and it still doesn't work.  Does anyone know how to fix this?  Thank you.

    You would need to open the Microsoft Mouse Software and change the settings for the Middle click.

  • control keyboard to scroll through the window of the observer?

    I use the current version of mail.app (9.3) in OS X 10.11.5 (El Capitan).

    I would like to be able to do basic operations of reading email with the keyboard controls.    There are keyboard shortcuts to create new messages, reply to or delete messages, move up/down in the list of messages in the message list pane, etc.   That's great.   But for most common task of simply read messages, support for the default is keyboard commands.

    In previous versions of Mail.app, I could use the arrow keys to move through the message list window and I couldn't use the previous page and next page controls (up arrow fn and fn-Basel on macbook pro keyboard) to scroll the message up and down view pane.   It was also possible to scroll up/down in message window using the space space and shift.   The page-up/page-down and SPACEBAR space/shift conform to the General conventions of Mac, including Safari.

    In El Capitan, it seems that this feature has been removed.  Instead, previous page and next page just cause scroll through the message list window.   Space does nothing.   A work around of all kinds is to hit the tab to move the keyboard focus in the list of messages display message, followed by commands to scroll, and then either hit tab twice or press shift + tab (but no space or shift-space) to focus back to the list of messages again.    It is not practical for an operation that I easily hundreds of times every day.

    Anyone has any ideas it is possible to restore the former function?   Hacks like hidden messaging preferences settings?    ... or a way to use the Resource Editor utility (what is the sort of thing even exist anymore?) to modify the application?

    Was it a former function that I have just forgotten or abandoned by Apple?   Or was it a bug or an oversight that it was omitted in the new version?     Doesn't have Apple deemed incompatible with the new directives of the interface?   This feature replaced some other keyboard shortcut that I don't know everything?    Y at - it a 3rd party plugin or something that I can use?   Any ideas would be appreciated.

    Space bar always works for me.

    Opt + arrow up / Dn also works.

    I don't know which would not interfere with these things. Perhaps a third-party app, but I don't know what.

  • How to change the keyboard shortcut to navigate through the tabs open in PS and AI CC 2014

    I'd love to put my own keyboard shortcuts to navigate through tabs open in PS and AI 2014 on OS X. I found out that this can be done with ctrl + tab to the PS, but I couldn't manage to make suggestions to the work of the forum of the AI. As said, I would like to define a 'standard' shortcut more like alt + cmd + arrow key at the same time of applications. If this shouldn't be possible, does anyone know a shortcut in AI CC 2014?

    Thank you very much!

    Amadeus

    In Illustrator, in my view, you can set these shortcuts in Edit > keyboard shortcuts > Menu commands > funny

    (illustrator can be also command-F6)

    Fact command + ~ (tilde key) work for you in photoshop and illustrator?

    I don't think you want to use alt + cmd + arrow key since it's repositioning/moving objects

  • Problem with the keyboard work is not on the computer.

    my keyboard works in BIOS, but not on windows, if I look in Device Manager, it seems that it is not detected, same result if I ask to install new hardware it says no new hardware found

    This problem is more than a FEW DAYS OLD?  How the question, "my keyboard works in BIOS but not in windows" would be only a few days old?  Don't you have the machine but left on? Heh

    If possible, restore back those days (if these days are before you wrote the question).

    The keyboard works in Mode safe?

    If so, the keyboard works for other users (create one if you haven't)?

    Is there any "unknown devices" in Device Manager?

    Other options that come to mind:

    1. Use the System File Checker tool to repair missing or corrupted system files
    2. Windows Vista repair install
  • Windows Installer does not work, and niether do the Windows updates.

    OK, so I recently installed Advanced System Care for a purchase price of 12.28.  After the installation he did in fact speed up my computer but now I cannot make the updates for windows update and I access windows install.  I went through the solutions on "windows setup will not work", and nothing works.  Help, please.

    Alissa.

    Hey alissa,.

    Disable Advanced System Care and see if the update works. If this works, contact the software provider for help on how to make it work with updates.

    Note: run the computer without antivirus software or firewall is a potential threat to the computer; don't forget to activate the security software after completing the troubleshooting steps and after you have identified the problem. Kind regards

  • Try to run a SQL statement through the window of OEM 12 c run SQL.  Statement fails

    All,

    I have a 11g database.  When it is initially installed, I installed it in $ORACLE_BASE = / orabin/app/oracle/product and $ORACLE_HOME = $ORACLE_BASE/11gDB_R2.  This is the version 11.2.0.1 to give birth to 11.2.0.3.

    Recently, I installed 11.2.0.4 in $ORACLE_BASE/11.2.0.4.  Then, I upgraded my database at 11.2.0.4.  Everything works fine.

    All my scripts on the linux host logon changed to point my environment at $ORACLE_BASE/11.2.0.4 House and my $PATH when I connect to the linux host is: /orabin/app/oracle/product/11.2.0.4/bin:/orabin/app/oracle/product/11.2.0.4/OPatch:/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/oracle/bin

    On my OEM Console, the database appears as 11.2.0.4 and me can manage very well.

    However, when I try to use the window of the OEM Console to execute SQL to execute any type of SQL statement, it fails.

    The failure error is:

    Could not launch/orabin/app/oracle/product/11gDB_R2/bin/sqlplus-s/nolog: no such file or directory

    It would be a mistake since the 11gDB_R2 directory tree (the 11.2.0.3 software) has been removed from the host, now that the database is set to level and working as 11.2.0.4.

    I wonder if somewhere in the OEM software, there is always a pointer to the old ORACLE_HOME?  I can't find anything in the .bashrc or other shell scripts that are executed when a Shell session on the host computer which were still the reference to the old directory of 11gDB_R2 so I'm a bit puzzled.

    I have 8 guests, and all have been improved in the same way at 11.2.0.4.  For some databases, the OEM window run SQL is executing the SQL code.

    Someone has some ideas on this?

    Go to the Configuration of the analysis of the database (when you set the password) and update of the Oracle home.   Also do this for all targets listener on this host as well.
