For various reasons, keyboards on both laptops and desktops may suddenly stop functioning properly. This is not a common problem, but when it happens, either some or all keys stop working (depending on the situation), or features of the keyboard such as backlighting may not work. Apple Discussion poster ' writes: 'I am having trouble with the keyboard but only with some keys. Like for example I press the play button and it goes to expose, or I press the volume button and it goes to the desktop. Also my brightness button does not work.
Please help me.' This kind of problem breaks down primarily into four areas: Low Battery, Physical Damage, Driver and Software issues, and Firmware Issues. Low batteries can affect the functionality of laptop keyboards via some indirect circumstances, and wireless desktop keyboards. For laptops, if you are running a full-screen application on relatively low battery, when the low battery warnings pop up you may not see them; at the same time, the keyboard may become unresponsive.
To remedy this, plug the computer into a power supply or connect an external keyboard temporarily to dismiss the low battery alert. For Wireless keyboards, replacing low batteries should help fix the problem. Physical Damage or Interference: If you have spilled water or other fluids onto your keyboard, the keys will short out and not work correctly.

Why won't command z not work when using adobe Illustrator etc? In OSX, but if you are in windows then it should be Control + Z. I can't use the Command Z option on any of the Adobe programs, yet they all work on my.
In the case of sticky or salty drinks this can be a relatively permanent problem, but in the case of pure water, as long as it fully and quickly evaporates you should be able to regain function of your keyboard. Use a canned-air blower to blast water out from between the keys and let the keyboard sit to dry for a while. Putting it in relatively warm and dry places can help speed this up. Only use the keyboard after it has completely dried.
For keys that stick after sugary liquid has spilled, you should be able to pry them up by inserting a fingernail under the top edge of the key and gently prying up while pressing on the bottom. The key should snap up and swing open, exposing the bottom surface. Use a damp (not wet) Q-tip to carefully wipe away as much sticky mess as possible, and check the button mechanism to make sure it is functioning properly. Then place the keycap back on and press down to snap it in place. Driver and Software Issues: Depending on the situation, sometimes specific key subsets-such as the Eject, Caps Lock, or the Function keys-may not work. This can sometimes happen randomly, or after running certain programs and especially other operating systems via Bootcamp.
There are several things to check when this happens. First, in later-model keyboards and computers, Apple has delayed the activation of both the Caps Lock and Eject buttons to prevent accidental activation so that quick taps wont activate the keys. Additionally, for F-key functionality, ensure the F-key behavior is set according to your preferences in the 'Keyboard & Mouse' system preferences. Under the 'Keyboard' tab, check or uncheck the 'Use all F1, F2, etc. Keys as standard function keys' according to your preferences. If it is checked, the default features (Brightness, Expose, Volume, etc.) will only work if you simultaneously hold down the 'Fn' key.
Lastly, be sure Number Lock is not activated, because this will make standard keys output numbers. This can be toggled on some computers and keyboards by pressing Fn-F6. Various system settings can also affect keyboard function. These are outlined by Apple in this knowledgebase. If you have third-party enhancement software, such as keyboard drivers from another manufacturer, or key remapping software, try removing it to see if the keyboard will respond properly. For Wireless keyboards, you might have some Bluetooth interference that may affect the functionality of keyboards.
Some people have reported that paired Bluetooth devices, such as mice, are accidentally recognized as having a button pressed down, which can prevent keys from functioning on the keyboard. To troubleshoot driver problems, try the following:.
Boot into safe mode Hold the shift key while booting up to load only essential drivers. Create a new account Account-specific settings that are faulty can affect input devices, so try creating a fresh account in the 'Accounts' system preferences to test the keyboard. Turn off Bluetooth and/or Wi-Fi Without booting into Safe mode, try turning off services such as Bluetooth and Wi-Fi. You will need to attach a wired mouse to do this. Unplug peripheral devices In addition to the previous suggestions, unplug all devices and turning off all wireless technologies.
Ensure Bootcamp drivers are updated. When running Windows in Bootcamp, run Apple software update to ensure the latest Bootcamp drivers are installed. These can be downloaded from the following locations: Firmware Issues Firmware and low-level hardware problems can interfere with keyboard function. In some cases this can be attributed to faulty keyboard PRAM settings, but in other instances USB ports can stop working, which may be the result of faulty SMC settings. For information on when and how to reset the PRAM and SMC, please read this MacFixIt.
Apple's built-in keyboards and mice are on their own USB busses, which in some laptop models is shared with one external USB port. In rare cases this can lead to interference with devices plugged into that port, so try removing USB devices. For desktops, trying different USB ports can also help track down the problem.
If you’ve recently upgraded to Windows 10 and now your keyboard isn’t working, you’re not alone. Many other Windows 10 users are reporting the same problem, especially after installing the KB4074588 update since February, 13, 2018.
And fortunately, there’s a solution. Here are 4 options to try. You may not need to try them all. Just work your way down the list until you find the one that fixes the problem. Method 1: Check your USB port is working Sometimes a USB port can just stop working when you upgrade to a new version of Windows.
Usually it’s because of a driver problem. You should always check for this problem first. Fortunately it’s easy to test: simply unplug the keyboard from the USB port and plug in another USB device – like a mouse or an external hard-drive.
If that device doesn’t work either, the USB port itself is the problem, and you should skip straight to. If the device you just plugged in does work, then continue to. Method 2: Adjust your keyboard settings Windows has a setting, called Filter Keys, that allows you to control how it deals with accidental repeated keystrokes. Unfortunately, if turned on, this setting has been known to cause some keyboards to stop working in Windows 10.

So you should check if it’s turned on. If it is, you should turn it off and see if that resolves the problem. 1) On your PC desktop, click the Action Center icon in the lower-right corner and click All settings.
2) Click Ease of Access. 3) Click Keyboard.
4) Ensure Filter Keys is OFF, and close the window. Method 3: Reinstall your keyboard driver If your keyboard driver has developed a fault, your keyboard may stop working.
To fix it:1) Right-click the Start button, then click Device Manager. 2) Expand Keyboards then right-click Standard PS/2 Keyboard and click Uninstall. 3) When prompted to confirm, click OK.
4) Restart your computer after the uninstall. If the problem persists, it’s likely that your driver is outdated, rather than faulty, and you should try below. Method 4: Update your keyboard and USB driver (recommended) One of the most common causes of an unresponsive keyboard is an outdated keyboard or USB driver. There are two ways you can get the right drivers for your keyboard and USB port: manually or automatically.
Manual driver update – You can update your drivers manually by going to the manufacturer’s website and searching for the most recent correct driver. Note that for your USB driver, you may need to try both the manufacturer of your PC and also the manufacturer of your USB port’s chip set. If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with. Automatic driver update – Driver Easy will automatically recognize your system and find the correct drivers for both your mouse and your USB port. You don’t need to know exactly what system your computer is running or who all the manufacturers are, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee): 1) and install Driver Easy. 2) Run Driver Easy and click Scan Now button.
Driver Easy will then scan your computer and detect any problem drivers. 3) Click the Update button next to the flagged keyboard (or USB device) to automatically download and install the correct version of it (you can do this with the FREE version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the – you’ll be prompted to upgrade when you click Update All).
