the keyboard does not have to return the system to the standby mode

Windows 7 Home Premium 64-bit system.

The fundamental problem is that, after working properly for more than a year and a half, this Win7 machine suddenly stopped enlightenment of the mode before using the keyboard a few months ago. It still immediately responds to a mouse click, then dysfunction of the keyboard was only a minor inconvenience. The keyboard is equipped with a PS/2 connector, the mouse uses a USB port.

However, several times lately the keyboard did not return after the awakening of the system; It is a biggest drawback. Each of these three times the keyboard had returned to normal after a reboot of the operating system, using the mouse to manipulate the Start Menu. I noticed nothing otherwise askew with the keyboard at any time, which suggests that this is not a problem with hardware keyboard. I would like to know how to get the system back to normal.

I don't know if the following is relevant, but it is similar:
There is a card audio semi professional, with its own control panel software, installed in the computer. With the exception of the occasional limited testing, I do no audio recording here, but I often work on audio recordings downloaded from other sources. Thus, the audio card is really only reading used mode.

A few months ago a question arose on the settings of the control panel to monitor a recording against existing tracks. Under Win7, the map control panel is configured differently that in previous versions of Windows, if the answer was not immediately obvious.

I worked on the necessary configuration changes in Control Panel of the card as a test to determine how this follow-up. I may also changed some settings in the console Windows, but I'm not sure. Unfortunately, unlike in versions previous OS, the Windows mixer table affect use of the sound card and it is possible that I got all inputs muted in the Windows mixer as a general precaution.

Put the system into "sleep" (in the Start Menu) is done several times during my normal day. After running these tests of control, I found that the card does not work after that system was return of the mode 'sleep'. Immediately after the trials I reset control panel of the sound card for my normal use. All seems OK for audio operation was normal except after public awareness of Sleep Mode.

Audio playback seemed normal in all applications. Programs appear to progress successfully through a recording during playback. Indicators like meters, position of playback cursor and displays the elapsed time has shown its normal operation, but nothing has reached the map output Sockets. I could not find any audio settings that seem to not correct. The Device Manager said that the card was working properly. Restart the normal audio returned BONE, as it does now (most of the time) for the keyboard.

I played with things for two or three weeks. I've posted questions on some audio related forums, but no suggestion had no effect. Finally, I was ready to uninstall the card its and its drivers, then reinstall, when I remembered on the System Restore Points.

I found there was a generated system restore point made a few hours before I did my test of the monitor-the-new-record. I used the restore point and the audio card to return to normal, the awakening with the rest of the system.

The only thing I could say to be uninstalled by the restoration of the system has a few updates of Microsoft Security Essentials. I immediately did a manual update of that, to ensure it would not be any effect on the audio. Audio worked properly since registration, including, but I have not retested monitoring check against existing tracks.

It was shortly after the keyboard problem has started. In this case I don't know what it is changed on the computer that could have led to the problem, but it seems not unlikely that some settings in the registry system is again wrong.

  • the button new folder does not have System File Checker says no breach of integrity

    Mem of Windows 7 64 bit, Sony VAIO, 8 GB, the latest journals to install checked no found error. Keyboard shortcut for the new folder does not work, but good ciick new-folder is there and works. Said it was problem-no hard drive problems, File Checker said no violations. Did usual defrg, reg cleaner, virus scans, etc. New folder button Windows Explorer stopped working after I upgraded my backup of instant backup software Memeo Memeo Backup Premium. When I return at the moment (the button) works when I uninstall Instant, it works, but when I insall Premium button no longer works. Explore premium a integration of windows and instant does not work. I say that the problem is because of this, but of coarse Memeo said it's a hard drive issue or microsofts problem. No hard drive problem, it's almost all scanned and new directions. The registry is scanned. I played in windows since 3.0.Granted I'm not a programmer, but I put togeather computers (all Windows Basic) since the 1980s. Did do a little programming for timex sinclair Boy I'm giving my age :) away  I solved just a poblem resolved not technicians at Sony. They told me that my only option was to restore my computer to factory State and again UGH!  Found the problem of sony, a former .exe file which does not have ugraded when needed, the deleted files and the sony program now works fine!  If the ideas on my "new folder button?

    Found the answer! It was just like I thought Memeo Backup Premium has a subprogramme called backup that he mixes with the Explorer of Windows 7, uninstalled this (backup) and the new record button works again. Memeo people had me uninstall the rest of the software and gave me a link to download the software less backup. Now, I'm trying to find out if I will return my money or a fixed copy. No answer yet! But I don't think they work on Friday, so I'll have to wait beyond Monday to see if they're going to answer me. I tracked their problem they should pay me ;)

    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!

    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.

    • 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.

  • a few keys on the keyboard does not not on my Sony VAIO flip SVF15N17CXB 15A

    Hello people,

    I have the following problem. Around a week ago my keyboard started acting strange. namely, the letter 'I' and 'E' started does not have to work. However, after a few typing continious finally typed the letters. then only the restrat might help. After a few days, it completely stopped working and a few other letters does not work as well now. These are: 'Q' & 'E', 't' & 'I' & 'G '. I'm typing this now with touchscreen keyboard, (fortunetely, it works perfectly).

    to make sure that this software is not related, attempted to use the keys in safe mode of Windows, BIOS, connected a USB OS but still no use, they do not work. even activated the sound tapped the keyboard, but the keys do not all sound.

    I tried to unplug the LED cable described as https://community.sony.com/t5/VAIO-Hardware-Networking/How-to-replace-Vaio-Flip-15-keyboard/td-p/507..., but didn't help either.

    The only reason that comes to my mind could cause, it's playing video games before that happens the keyboard events. I think that overheating caused it, is it still possible that warming could cause some embarrassment on the keyboard keys?

    Coulf you please advice any other thing that might fix my problem before I'll order a new keyboard on eBay?

    I'm on m holidays and this completely spoiled my mood. Please help, community of Sony.

    Ordered keyboard, succeeded him myself, using the replaced keyboard now to type this message.

    All good, all good.

    Sounds like keyboard problem.
    The operating system uses the pilot to clean keyboard and generally it s not necessary to reinstall the special keyboard driver.
    But one thing is really strange; the yellow exclamation mark in Device Manager

    Eventually it s only a problem of software in such a case, a system restore can be useful...

    Have you checked if the keyboard works in the BIOS?
    Do this!

    If the keyboard does not work in the BIOS, then you will need to replace the internal keyboard with the new.

  • 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.
