A nonfunctioning keyboard can seriously affect productivity in a workplace. A number of software and hardware issues can result in your company's keyboards becoming unresponsive. In most cases, restarting your computer will resolve these issues. If that does not work, there are a series of tests and procedures of you can perform to diagnose and then unlock your frozen keyboard.
Press "Windows+C" on your keyboard. If the Windows 8 Charms menu appears, your keyboard is working properly, and it's likely the application you're using that's causing the keyboard to freeze. Restart the application and try using the keyboard again.
Verify that the cable connecting the keyboard to your computer is securely fastened if you are using a wired keyboard. Cables can be jostled, causing them to come unplugged. When reconnecting an unplugged PS/2-style keyboard, check that its pins are not bent. If they are, gently straighten them with your fingernail.
Verify that the keyboard is not outside of its transmission range if you are using a wireless keyboard. Bluetooth keyboards have ranges of approximately 30 feet. Attempting to use a Bluetooth keyboard beyond this distance may cause it to stop functioning as it should.
Reestablish the pairing connection between your Bluetooth keyboard and computer. Start by turning off your keyboard or switching it out of discoverable mode. Swipe to the right side of your computer screen to display the Charms bar. Click "Change PC Settings" and then click "Devices." Turn your keyboard on again and set it to discoverable mode. Click "Add a Device" and then click the name of your Bluetooth keyboard. Type the passcode provided on your screen, if prompted.
Update the keyboard drivers. To do this, swipe your mouse pointer to the bottom-left corner of your screen, right-click and then select "Device Manager" on the menu that appears. Click "View" on the Device Manager menu and click "Show Hidden Devices." Click the arrow next to Keyboards on the Devices Manager list to expand the list of keyboards. Right-click your keyboard and select "Update Driver Software" to have Windows update the keyboard driver.
Reinstall the keyboard. Swipe your mouse pointer to the bottom-left corner of your screen, right-click your mouse and then select "Device Manager" on the menu that appears. Click "View" and then click "Show Hidden Devices." Click the arrow next to Keyboards on the Devices Manager list to expand the list of keyboards. Right-click your keyboard and select "Uninstall." Swipe your mouse pointer to the right side of your screen and click the Settings charm. Click "Power" and then select "Restart" to restart your computer. Windows will automatically reinstall the keyboard when your computer restarts.
To fix it when a mechanical keyboard key isn't working or is unresponsive, unplug the keyboard or remove its batteries before trying to fix it. Try a different cable and clean the keyboard. Pry the keycap off the unresponsive switch, hold the keyboard upside down, and blow out the switch using canned air. You can also use contact cleaner on the key switch.
If your keyboard keys are sticky, turn off the computer and unplug the keyboard. Gently dislodge the sticky keys using a key puller, moisten a cotton swab with isopropyl alcohol, and clean the keys and plungers. Replace the cleaned keys and wait until everything is fully dry before plugging it back in.
If your keyboard is typing the wrong characters, disabling Num Lock may fix your problem. If not, you may have inadvertently changed your keyboard layout. Click the language button on the taskbar to check. You can also try running the Windows keyboard troubleshooter to see if this solves the problem.
Computers are fairly straightforward. When you type on the keyboard, the corresponding letters are supposed to appear on the screen in front of you. But at some point, all that typing will produce nothing. That means you likely have a frozen keyboard.
In troubleshooting, it's best to start simple and work from there. If you're using a desktop, check to make sure the keyboard is plugged in. If so, unplugging it and plugging it back in could do the trick. If that doesn't work, use your mouse to restart the computer.
If your keyboard is frozen and is a wireless device, your issue may be battery-related. Replace the batteries with a fresh set and check to see if it fixes the problem. If you have a multi-device keyboard, you may also find it has a power switch. Make sure that hasn't been toggled to "off." If this isn't the case, the drivers your computer is using could be out of date. Update the drivers and see if the problem is resolved.
If you're using a wireless keyboard connected by Bluetooth, you have a limited range, so it may simply be a matter of moving your keyboard closer to your computer. However, it could also be that you've lost your connection. If your USB receiver has a reset button, pressing it should resolve the issue. If not, search for instructions for resetting specific to your keyboard model.
If you have a laptop or unplugging your keyboard doesn't work, the problem is likely within the computer. If you have a Windows computer, instructions on how to unlock a keyboard will start with rebooting the computer. If that doesn't work, restart and press the "Escape" key to see if the Startup menu displays. If it doesn't, you'll need to replace your keyboard. If it does, you'll need to press F10, which will get you into the BIOS settings. You'll then press F5 to reload and F10 to accept the changes. Restart and see if this allows you to work as usual.
If not, open the Control Panel, click "Hardware and Sound" and choose "Device Manager." Here you should see a keyboard listed that you can uninstall and reinstall. After this process, reboot to see if your keyboard works.
If your frozen keyboard is on a Mac computer, first unplug the keyboard and plug it back in. If that doesn't work, connect your Mac to an outlet. Your computer may also have accidentally turned on a setting. Choose "Apple Menu," then "System Preferences," then "Keyboard" and finally "Input Sources." Choose "Show input menu in menu bar" and look in the input menu to make sure your preferred keyboard layout is selected.
If you're typing and your computer isn't responding, it may not be the keyboard. When a computer locks up, nothing works, including the mouse. If that's the case, you'll have to do a hard reset, which involves holding the power button down until your device powers off. Wait several seconds and press the power button again.
Nobody wants to deal with their PC suddenly freezing while in the middle of working. Next time you need to fix a frozen computer and don't want to restart, there's a little-known shortcut that might help you recover from a common problem.
Depending on the cause of the freeze, this shortcut may or may not fix your issue. If your graphics driver gets stuck, restarting it should let you continue on without having to restart your computer. But if this doesn't work, your PC is probably frozen from something more than your video card.
Should neither of these work, give Ctrl + Alt + Del a press. This is a special key combination that only the operating system can respond to, making it an important step when checking for a frozen PC.
If your computer is frozen and Ctrl + Alt + Del isn't working after some time, you'll need to hard shutdown your computer by holding its power button for several seconds. Should that fail to work, and you're using a desktop, you can pull the power plug. While it's best to avoid doing this unless you absolutely have to, sometimes it's the only way to escape a full system freeze.
I have a 4 year-old Studio 1737 laptop that has worked very well until just now. When I checked email an hour or so ago it worked fine, but the last 15 minutes the keyboard has completely frozen. I tried rebooting, but it didn't help (I couldn't even log in) and is still frozen. The wireless mouse works fine and this plug-in keyboard I took from a desktop in my house works fine, too. How can I unfreeze my keyboard? I'm tempted to reset to an earlier save date, but I wanted to ask here first. Thanks in advance for any help!

I was on my Macbook Pro laptop last night and all of a sudden, the mouse have frozen on the screen and the keyboard is not working. I switched it off at the power button and switched it back on again x3 times and the same thing kept happening. I tried it again this morning and the same thing happened. Has my laptop broken or anything as i can't do anything with it or is there a keyboard shortcut i could use to relaunch the finder?
it could be that the ribbon cables for the keyboard and touchpad are not attached correctly and move in certain situations, causing them to no longer be fully connected. Follow the manufacturer's instructions to disassemble the keyboard and check the ribbon cable connection.
On the other hand, I could fetch this exception (duplicated many times at the exact time when duplication frozen scenarii appeared) in the EVENT Logs : HotKeyServiceUWP.exe, version : 18.104.22.168952:
NOTE: The command keyis also the Apple key and the option key is also the alt key. The eject keyis found on the top right of your keyboard.
A frozen Mac is a rare occurrence, but Macs (like all computers) run in cycles, and sometimes the software gets stuck in a loop. When this happens you may find an app like Word, or the whole of macOS, becomes unresponsive.
After rebooting my MBPr, it is now frozen at the login screen showing the list of users. I'm unable to move the cursor or use the keyboard. Booting in safe mode does the same thing. A few days ago, I updated Sierra to 10.12.4, so it might be related to that. Right before the problem happened, I was pruning old third-party Launch Agents and Daemons, but I did not delete any from Apple. That might be related, but I don't know for sure, since I very rarely reboot the computer. 2b1af7f3a8
