how to fix keyboard not typing?

Keyboard is the main instrument to typing by hand. One of the typical panic moments is when there is a sudden stop of the keyboard. Be it a luxurious work typewriter or you are typing on a laptop rubbery keyboard, a nonresponsive keyboard makes your day. The majority of the keyboard issues are mere software glitches or connection hiccups and not a failure of the hardware. You should do a systematic troubleshooting process before rushing out to purchase a replacement and you will have the machine going in the next few minutes.

The simplest thing is that one should first verify the physical connection. To reset the handshake between the device and the computer, to the wired users, unplug and re-plug the USB connector preferably into another port. When connecting a wireless or Bluetooth keyboard, be sure that the batteries are not collapsed and the Connect/Pairing button has not been switched off accidentally. The unspoken cause of occasional lagging or complete loss of input is often interference by other electronics or a low battery.

• Knowledgebase Software Patches and Drivers.
• In case the hardware appears to be physically healthy, then the problem must be in the settings of your operating system. It is possible to look at Filter Keys among the accessibility options in Windows that can overlook repetitive or short keystrokes. It can render the keyboard dead in case it is turned on accidentally, usually, by holding the Right Shift key eight seconds. This is a popular magic fix of disabling in the settings of Ease of Access. 

Other than environments, the most common place of software failure is at the driver level. The keyboard drivers may get corrupted over time or may be outdated particularly when there has been significant upgrade of the operating system. You can press the keyboard through the device manager and press the uninstall device option and then re-open the device manager after which you restart, this makes the computer install a new driver. This removes any digital cobwebs that may have been impeding hardware and software communication.

Internal Service and Laptop-Specifications.

The issue can be more local among the laptop users. One key that is stuck (Ctrl, Alt or Shift) will put the entire keyboard in lockout and no other input will be registered. Your best friend is compressed air, blow the dirt out from under keycaps to get the physical blockages out. Unless certain keys fail to work, then it is likely to be dust or slight spillage. When the whole internal keyboard is not responsive, ensure that no recent windows update has been installed or a glitch in BIOS has turned it off.

In exception cases, it may be broken keyboard, though it may be a frozen OS. When your mouse pointer fails to move as well, it is possible that the entire system has just crashed too. The final step that is a hard reboot which is also common-sense and involves pressing the power button till the machine re-boot. When it is functioning in different BIOS/UEFI menu, but not in your operating system, you can be sure there is nothing wrong with the hardware, and you may need to spend more time in your software environment or restore the system to resume typing.
