• keyboard has suddenly stopped working

  Hi all, my keyboard has suddenly stopped working. I was installing an upgrade of El Capitan (later) and when the computer is restarted, it gave me this message that the bluetooth keyboard was not detectable. Well, I don't have an external keyboard, just the Interior came with the laptop. I have reset the pram and it still does not work. I looked at the system preferences and beach seems to be in check. Is it time to this service or do I still have options?

  Thank you

• Capacity wireless suddenly stopped working after an update of Windows Vista.

  Feature WiFi suddenly stopped working after a windows vista updated.  Wireless switch is engaged, but stays yellow that messeges troubleshooting all say computer does not detect wireless devices.  It's as if someone pulled the unit and the antenna of the portable computer.  I also downloaded the wireless drivers and Setup several times without success.  Wireless device appears in the Device Manager page.  The only thing that is showing and work is the cable which is how I can download the drivers and appear on this forum.  Is it possible that the wireless device is broken?  All applicable lights are lit on the networking modem, no signal is detected on the computer, I have concluded that the wireless on the laptop is just inop.  Either way, I have a Compaq Presario F700 laptop.  All the options out there?  Thank you

  original title: can't find the wireless device

  Hello again, Kathy,

  More specific instruction, I can give to check settings in the BIOS of your system is to search for a list of devices that installed your laptop. There are only two options for each device, activate them and deactivate them.
  Look for something listed as network radio or wireless card and make sure that it is set to enable.
  The option that you network adapter found can also control the wireless adapter, but it can control only the plug adapter (Ethernet) network.
  A simpler solution, if you have not already tried it it is the system restore in Windows as mentioned by Kiran in a previous answer:

• Service Windows wireless suddenly stopped working because of problem with the KeyIso service

  Description of the problem: Windows Wireless Services suddenly stopped working on my computer. What I have discovered so far that the problem is that the WLAN AutoConfig service does not work because of the failure of the function "KeyIso". The error message for the mentions "Error 126" KeyIso (the specified module could not be found). Any help to fix this would be appreciated. TDW

  Hello

  What is the antivirus installed on the computer program?

  KeyIso Description:

  The service provides insulation for private keys key processes and operations of such associated encryption required by the common criteria. The service stores and uses long term keys in a secure process in line with the requirements of the common criteria. It should normally be disabled, as otherwise, these cryptographic operations may fail.

  Looks like there could be a corruption with the wireless connection that you have added. You can perform the steps.

  Method 1:
  

  Try to manually start the wireless service, i.e. the WLAN AutoConfig service. To do this, connect to the computer as an administrator.

  a. Click Start, type services.msc and press enter.
  b. Locate the Autoconfiguration WLAN service, double-click to open its Properties window.
  c as. under the general tab, change the startup type to Automatic and click on the Start button.
  d. click on apply, then ok.

  Method 2:

  To resolve this problem, try using the tool (SFC.exe) System File Checker. To do this, follow these steps:

  Method 3:

  You can uninstall and reinstall the network card and check.

  a. click Start, type Device Manager in the Start search box and press enter.
  b. locate the network adapters and expand the same.
  c. Select the Wireless connection, right click and choose Uninstall.
  d. restart the computer, if prompted.

  Drivers should settle automatically after the computer restarts.

  Now you can install the latest network card drivers and see if that fixes the problem.

• Re: Wireless suddenly stops working after traveling abroad

  Toshiba Satellite L402, WXP

  Before you travel my laptop wireless works perfectly, after traveling abroad, I tried to connect to my network wireless at home, but I can't see any wireless network.

  I have two computers at home, PC and laptop, the PC has no any problem connecting to the wireless and can see all available wireless network, while my laptop has his red X mark on its icon on the quick launch wireless and can not display any network without wire around, I have re installed the driver but still it won't work , I tried to connect my psp and portable to my wireless router just to check if the connection to the router is limited, but I was able to connect to it.

  Any idea on what I need to check or do? Thank you!

  Hi guel27,

  -have you checked if the wlan switch is in the correct position?
  -If the position is ok, check the hardware by using Device Manager. No red or yellow cross on the wlan adapter? Okay, you guys:
  -check if the network connection is not disabled in the overview of network connections
  -(droite-klick sur réseau/wlan-icon dans la systemtray et vérifiez votre connexion si elle est désactivée.)
  seing any Red Cross on your wlan conn? Okay, you guys:
  -Perhaps you have installed a wireless Internet favorite, at least you could:
  -delete all favorite connections and choose dhcp instead of a static ip address

  BTW: Be sure to use the driver for your nic corect!

• My stand-alone version of Lightroom (6.3 v) has suddenly stopped working, and it will not yet launch!

  Its been working perfectly reliable on a 10 Windows PC until yesterday and now... nothing!  If I click on the shortcut on the desktop, or try to run the application, it is even not a splash screen is displayed.  But when I look in the Manager of tasks, looks like Lightroom trying to start a background process, but after a few seconds that he faints - there is no sign of work even in the background.  But I see that there is another application from Adobe that runs and faints at the same time - called Adobe 32-bit utility License (even if I'm under 10 64-bit Windows)

  My PC seems to work very well, outside of Lightroom.

  I'm stumped, but before I try going through the whole palaver of an uninstall complete and reinstall, I thought I should ask for help!

• Wireless just stopped working...

  Internet Wi - Fi my computer just suddenly stopped working.  It is not yet a signal at all even though my roommate's computer captures very well the signal.  Any ideas?

  Hello

  Could easily be hardware and you don't describe system or device.

  Look on the front or side of the computer and are looking for a switch for WiFi (some have) and if an external
  check the connection.

  Actually try updating your driver and disabling the network logon. Use a connection cable or download
  on another machine and transfer using removable media (CD, DVD, USB and so on).

  Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
  version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
  Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  Repeat for network (NIC) card and is a good time to get the other updated drivers as Vista like

  I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they

• DVD-CD ROM DRIVE SUDDENLY STOPPED WORKING

  My DVD - CD rom suddenly stopped working.  It does not appear on my computer.  In Device Manager, it shows the exclamation point in a yellow triangle and has the following: Windows cannot load the driver for this hardware device.  The driver may be corrupted or missing. (Code 39).  I tried updating the driver, and he said that the best updated driver is already installed.  But it won't work.  When I put a disc in, the green light as it tries to work, but nothing.  In the properties in Device Manager, he suggested looking for a microsoft solution and I did it and there is no solutions.  Help, please!  I have install all the recommended and important updates, I have this game automatically.  I have Vista service pack 2.  Apart from this, the computer works fine.  I appreciate any help you can offer.  Thank you.

  Hello

  Code 39 means that the driver is corrupted or missing.

  Do this - control panel - Device Manager 1 - click double-click on the drive - CD/DVD
  Driver update (this can do nothing as MS is far behind the drivers of certification). Now LAW
  Click on - UNINSTALL - REBOOT - this will rebuild the driver stack.

  Normally the above will solve this problem otherwise working your way down through them, even if you did
  them before.

• The keyboard and mouse bluetooth suddenly stops working

  I asked this question before using Dell, but none of the answers provided.
  The keyboard and mouse bluetooth suddenly stops working.

  Given that this only happens when I'm online I make this question to the FireFox support.

• USB mouse and keyboard suddenly stopped working

  My USB connected Microsoft USB Bluetooth mouse and keyboard suddenly stopped working today. After researching everything I could, I didall that I could find as a possible solution that has been:

  • Update of the chipsets
  • Uninstalling usb in Device Manager and reboot devices
  • Updated via Device Manager, usb devices
  • Reformatting and reinstalling Windows 7
  • Stop, unplug and allow the card mother "reset".
  • Try multiple ports
  • There is no 'connect' button on my mouse so I can not sure try this
  • Replace the batteries in my mouse
  • Obviously both devices have been connected
  • Updated the software for the mouse

  I have tried literally everything I could think of or read previously and I am out of options. Oddly enough however, after reformatting and reinstalling windows, my USB storage device is found and is working, but the keyboard and mouse are not. Please don't bother not suggest anything I listed above, I obviously already tried and found no chance.

  Update
  I have solved my problem. For later use, if anyone has this problem and no other solution seems not work; That's what I did.

  I bought a USB 2 ports PCI card and installed in my computer, then go back to Windows XP. While my original front and rear USB ports still recognize a flash drive, they do not recognize the keyboard or USB mouse, make ports PCI card. I had also updated ALL the updates of windows on the site, not the auto update available on the desktop. Although I don't know the cause, I am certain that somewhere, something was is altered by the hardware or software, and my default USB ports do not recognize mouse or keyboards.

  Another piece of knowledge in case anyone is interested; I use a card mother gigabyte s-series and my nvidia video card GeForce previously is no longer recognized in the port, it would cause my computer go into a State of hibernation and the monitor would go into "Analog Power Saving Mode". The only solution was to spend a friend with my video card. (Its graphics card is a GeForce 9800 GTX, mine was a GeForce 9800 GT. No reason why it should make a difference.) According to me, even if my computer is less than two years old, I was sold a bad mother. I read online cases in other forums for technical support of people having the same problem. Gigabyte motherboards stop random ports for no known reason.

• resolution 2560 x 1440 has suddenly stopped working. 1080 p now the max option available

  I have 2010 macbook pro (el capitan) and ASUS H257HU monitor that supports the resolution 2560 x 1440. Until yesterday, I was able to get the full resolution, but suddenly it has stopped working and the max resolution I could get was 1080 p.

  I tried to reset the smc and NVRAM, but that did not help.

  In safe mode, I followed the suggestion of apple and was able to get resolution of 2560. But it reboots the machine back to 1080 p. Hold down the option key and clicking on the option scale does not display any resolution above 1080 p.

  I've tried searching and following some recommendations, but no permits.

  Restart the computer and enter views sometimes give 2560 option, but clicking on it makes the screen turns blue and then it always comes back to 1080 p, with no options available in the dialog on the scale. The System Preferences dialog box hangs for a few seconds.

  Someone at - he fell on the same issue and found a solution. I don't know why he suddenly stops working, while still being able to work in safe mode but not in normal condition. I tried to remove the profiles as well.

  With bootcamp (win 7), the display works fine with 2560 x 1440.

  The connector I use is screen Mini DisplayPort.

  All proposals/solutions will be very well received.

  Hello there, moths.

  It seems that you are having problems to select the resolution you want on your external display from ASUS. Great job with the troubleshooting, you've done so far. The following Knowledge Base article offers strong information to look over and review, as well as links to some additional troubleshooting content:

  Get help with graphical problems on external displays connected to your Mac.

  Before you start

  You can solve many problems of display by updating the software on your Apple devices, cables and adapters. If you see an image on your screen, look for the software updates using the Mac App Store:

  1. Connect your external display and Apple video cables or cards that you use with it.
  2. In the Apple menu, click App Store.
  3. Click updates in the window of the App Store.
  4. Install OS X updates or firmware are listed.

  If you use a display, hub, extenders or adapter not made by Apple, check with the manufacturer for updates that might be available.

  If you try to connect a screen 4 K or Ultra HD TV with your Mac, make sure that your computer meets the requirements for the use of these external displays.

  If your firmware and software are up to date, or if you don't see the image on your screen, try the steps below for your specific problem.

  {...}

  Check the connections

  Check the connections on your Mac and external screens:

  • If you use an Apple laptop computer, try to connect the AC adapter.
  • Make sure that the power cable from the external display is connected correctly and that your display is enabled.
  • If you are using a Mac Pro (end of 2013), make sure that your screens are plugged into the right ports.
  • If you use a hub of display, Cabinet or "KVM", try to connect the video cable from your screen directly to your Mac instead.
  • Unplug the video cable where it plugs into your Mac, then reconnect to reinsert the connection.
  • If you are using a video card, unplug the video adapter on your Mac, then reconnect to reinsert the connection.
  • If you use multiple video cards to connect your screen (the cards are "chained"), testing connection of the screen by using a single adapter if possible. Some video cards may not be linked together. For example, a mini DisplayPort to DVI adapter may not be connected to an adapter DVI to HDMI.
  • If your screen has more than one video connection, see if you are using another connection on the display works. If possible, check if you use a different view or a different adapter works.
  • Try using another cable that you know to be in working condition. Check with the manufacturer of the screen to make sure that you use the cable they recommend.

  Detect your display

  If you use an external monitor, sleep and wake your Mac to check for connected screens:

  1. Press the power button on your computer to standby, or choose the Apple menu > sleep.
  2. Wait a few moments, and then press a key on your keyboard or click your mouse or trackpad to wake up your Mac.

  If you use more than one screen, and you can see the image on one of the screens, you can also use the preferences monitors to check the connected screens.
  

  Adjust video settings

  If there is no image on the screen, try adjusting the brightness or contrast of the screen. If there is still no picture or image appears torn, or scrambled, try selecting a different video resolution in system preferences. Adjust brightness

  • If you use an Apple Display Monitor, press the key to increase brightness your Apple keyboard. To adjust the brightness of a secondary screen, press Control + F2.
  • If you use a view that is not made by Apple, see the documentation that came with your monitor to see if it includes built-in controls to adjust the brightness or contrast.

  Change your display resolution

  1. In the Apple menu, choose System Preferences.
  2. Click the display icon.
  3. Click default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the ESC key to cancel the change.
     

  If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.

  If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

  Search for software third display

  If your monitor only works when your Mac is started in safe mode, and related to the software display is installed, check with the developer of the software for updates, or try to uninstall temporarily.

• Satellite A500 - 15N Wireless has stopped working

  I bought my A500-15N in last October and had no problems at all with wireless connectivity. Last night when I was surfing Internet it suddenly stopped working (literally between two pages on Wikipedia) and I can connect is no longer. When I try the troubleshooting option, I still see an error 'wireless capability is turned off. I not made any changes to my router or laptop, so I'm not sure what could be going wrong.

  Is the wireless adapter fuck and I need to get this replaced? I tried the combo FN + F8 but which does nothing either.

  Hey,.

  Is the WLAN card still listed in Device Manager correctly and have you tried another key FN if combination work?
  Usually the WLAN card can be disabled with the FN + F8 key combination you wrote

  In your case I would recommend updating the driver WLAN. You can download the latest driver WLAN here:
