my wireless keyboard does not work after the upgrade to El Capitan

I have a wireless trackpad, keyboard, and mouse connected to the iMac of 2013. Everything works fine until I upgraded to El Capitan a few weeks ago. Whenever I wake the system from standby mode, I am unable my password key using the keyboard. The keyboard no longer respond or begin typing the characters on his own.

So I did a little research on the Internet and discovered by turning off the wireless trackpad will solve the problem. So I tried and yes it works. But it also means that I have to turn off my trackpad whenever I need to connect using my keyboard, which is not the best solution. And my keyboard and trackpad have always been placed side by side, works perfectly well until this upgrade of the OS.

Does anyone have a solution to this?

Thank you

Have you tried to remove the keyboard and the trackpad of Bluetooth devices in the bar of Manu. Then allowing them to be discovered again.

(You may need to hold down option when you select Bluetooth)

  • the Lenovo g500 mouse does not work after the upgrade to windows 8.1

    I recently upgraded my g500 windows 8 for winows to 8.1. But ever since then, my mouse does not work and the keyboard works only after standby. I tried to restore the default settings, but that didn't help. What can I do to fix this?

    Hello

    If the system is still under warranty,

    I suggest that to call a repairman,

    If this isn't the case, you can try to check the keyboard and the Touchpad connection.

    You can consult this service manual

  • On my trackpad scrolling does not work after the upgrade to 12.0

    On my trackpad scrolling does not work after update Firefox from version 3.6.28 to version 12. It normally works in Thunderbird, and other applications. It is a Lenovo T61 with XP Service Pack 3 and all drivers up to date. Version 3 seems to have bad memory leaks so I would like to upgrade, but I can't do it without scrolling. I would appreciate any advice.

    Try to change the pref ui.trackpoint_hack.enabled on the topic: page default config-1 to 0 or 1 to see if that makes the work button.

    Close and restart Firefox after changing the ui.trackpoint_hack.enabled preferably.

  • line of numbers under the function keys keyboard does not work after windows upgrade

    Upgrade from Windows Vista Home Premium 64-bit window Ult 64 bit. Line of keyboard under func keys works not just if online using Windows Explorer, Firefox Safari n - numbers don't work - some type; other type letter k; with the SHIFT key, signs and symbols, type anything. I can get the numbers of t using my keypad and numlock. I have tried 3 keyboards.  One was a Microsoft USB 4000 ergonomic keyboard brand new and it had the same problems.  My keyboard USB wireless transmitter had the problem too.  All have the same problem. The keys are correct by using Word, Wordpad, etc.. Quick test repetition key online as well as the keys were all ok then.

    This started happening immediately after I upgraded to windows 7 ultimate.  I use a desktop HP Pavilion a6667c with 8 GB of RAM and the latest updates available for windows ultimate.   The problem occurred before and after the upgrade to service pack 1.   I noticed other people on the web posting on this problem too.    I got no error message when using Vista Home Premium 64-bit version and had installed all the latest updates him as well.

    The only solution I found to this problem is to build me a small table of characters and symbols, I can't do it, and sticking them in when I am online using one of the three browsers I use most often.   I looked at my keyboard settings and changed back and forth between American and British English British without any result.

    I'll post my problem of keyboard on HP forums as well.   Thanks for any help anyone can give me or leads.   Somewhere, I think that it is a simple problem to solve, but I searched and searched and browsed and traveled for several days to find a lot of people who have this type of keyboard problem, but no solution yet.

    I was able to solve the problem on my computer Microsoft Vista but uninstalling constant guard I had downloaded and installed with free Norton from Comcast. I got this tip on another thread and after followinging their advice, I was free to use my line of numbers/symbols of the keys even once! I was able to close my copy of the email and the character or symbol and the last sheet in Word.

  • Mouse does not work after the upgrade to Windows 7.

    I recently installed Windows 7. All right, except that my mouse does not work. I tried several types: series, USB, PS/2 and wireless. I even bought a Microsoft Mouse, but while the keyboard is very well the mouse still won't play.

    Hi Jollydiver,

    Thanks for posting. You will need to contact HP to see if there is a driver available for Windows 7 chipset.

  • new tab (+) does not work after the upgrade to v 23.0.1 forefox

    I had firfox version 22 I guess... Now, today morning I upgraded to v 23. It displays a message from one of the plug-in is not compatible with wud and therefore be disabled. now later I still once downloaded the plug in to check if its works or not but TI worked (as I had already guessed), or its display in modules or plug-ins.

    Now I don't get why the new tab does not work. Not at all. Its so very annoying. I googled the question and tried to reset firefox and the new tab in subject parameter: config. But nothing helped.

    I think that its because of this plug-in I've read somewhere that the parameters can be getting replaced by one of the defective Add-ons.

    Help, please.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/Firefox/tools > Modules > appearance).

    • Do NOT click on the reset button on the startup window Mode without failure.

    You can use the SearchReset extension to reset preferences to default values.

    Note that the SearchReset extension runs only once and then uninstalls automatically, so it will not appear on the page "> Firefox Add-ons" (topic: addons).

    If you do not keep the changes after a reboot or have problems with preferences, see:

  • HP Probook 6465b: Broadcom 4313gn does not work after the upgrade to Windows 10

    My laptop is HP Probook 6465b (model 2012) it came with Win 7 Pro pre-installed.

    I upgraded Win 10 and after that a Wi - Fi connection does not work. Then I tried the new facility, but it's the same thing.  I have come back to Win 7, but I would like to upgrade Win 10 if I can get the WiFi adpter for work.  My laptop otherwise works fine and it is not that old so I am confused why this wi - fi adapter gives me grey hair.

    Here is what happened:

    Just after upgading wi - fi works very well until the first stop. After reboot, free WiFi does not work and there is no wi - fi adapter in Device Manager. However, it's there, but it is hidden.

    I tried freezing and relocation of the map and I downloaded the latest drivers from HP Support, but I can't get the adapter to work.

    To get the internet to work I plugged USB wi - fi adapter and suddenly the WiFi Broadcom card started working also. She even worked after unplugging the wi - fi USB adapter but after reboot internal wi - fi adapter was missing again well (hidden and does not), it is too compligated to do each time and she even does not work every time, just every now and then.

    Any suggestions?
