Why don't computers have touchscreen keyboards

Solutions when keyboard or mouse do not work

In everyday PC life it is not so rare that the keyboard or mouse turn out to be stubborn and refuse to work. If the input peripherals are connected to a Windows 10 PC, there are a few solutions to resolve the blockages.

EnlargeSolutions when keyboard or mouse do not work

Check the peripheral devices: First, make sure that the connections between the computer and the input devices are good. If the mouse and keyboard are correctly connected and problems still occur, switch to a different USB port. Notebook users should also check whether they have accidentally deactivated the input devices using the function keys or a key combination.

If you use wireless devices, you should make sure that the associated USB receivers are correctly connected. A check of the battery or rechargeable battery does not do any harm. Some models require a minimum amount of energy to operate in order to be able to work at all. If in doubt, replace the battery with charged versions.

If that doesn't help, connect the devices to the computer with a cable. If the devices work here, then you can at least rule out a defect. If it is not possible to connect a cable, try using wired versions of the mouse and keyboard. In this way, you can at least narrow down whether the wireless input device is actually broken.

EnlargeSometimes reinstalling the device drivers can work wonders if your keyboard or mouse is causing trouble.

The last option is to plug the peripherals into another notebook or computer. If it works there without any problems, you at least know that the problem is with your PC and not with the peripheral devices.

Check from Windows: A rather rare cause of disused input devices can be malware that actively prevents the use of a mouse or keyboard. The goal of such an attack is to completely deny you access to the PC. In this case, you need to get Windows 10 to look for the malicious programs. Use bootable USB sticks for this, which most antivirus software manufacturers offer free of charge. With their help, the infected files can be found and deleted.

Alternatively, Windows Defender can also do this: Boot your computer in Windows 10 safe mode by pressing the key combination Ctrl-F8 immediately after switching on the computer. If that doesn't work because your system starts too quickly, go to "Settings -> Update and Security -> Recovery" to "Advanced Start" and click on "Restart now".

EnlargeAlternatively, the mouse pointer in Windows 10 can also be controlled with the arrow keys on the keyboard's number pad.

After the restart, select the option “Troubleshoot -› Advanced Options - ›Startup Settings” and click on “Restart” again. Windows will display an options menu from which you should select “4) Enable Safe Mode”. With the operating system started in Safe Mode, type virus & threat protection in the search box next to the Windows icon. Then click on “Scan Options” and select “Windows Defender Offline Scan”. With a click on the "Check now" button, the system will restart and perform a detailed scan. Once the process is over, malicious files will be removed automatically. You can view the results in the Virus & threat protection menu under Protection history.

Check the Windows drivers: Windows 10 actually handles the fully automatic installation of device drivers well. Sometimes it can help to force the system to reinstall the drivers. To do this, right-click the Windows logo in the taskbar again and call up the "Device Manager". It lists which devices are on and in your PC. Look for "mouse" and "keyboard". Expand the respective entries by clicking on the small arrow next to the entries. Right-click on the device and select "Uninstall device" from the context menu. We recommend deleting the keyboard driver first and then the mouse driver. The reason: If both drivers are removed, you will no longer have an input device until the next restart. Confirm the system prompt again and wait for the uninstallation to be successful. Restart the computer by briefly pressing the power or reset button on the housing. Windows 10 will automatically reinstall the drivers the next time it starts.

EnlargeIf the keyboard and mouse do not work under Windows 10, short-term workarounds can help. But there are also long-term solutions.

Short term solutions: Sometimes you just want to get something done on the PC quickly and can't find a long-term solution. If the mouse then does not work, bridge the defect by controlling the mouse pointer using the arrow keys on the keyboard's number pad. To activate the function, use the Windows – I shortcut to call up “Windows Settings”, use the tab key to switch to the sub-categories and use the arrow keys to navigate to “Easier to use”. Again, you can use the tab key to access the options on the left-hand side. There you navigate to "Mouse" and confirm with the return key. Use the tab key to reach the slide switch under "Control the mouse using a numeric keypad". Use the space key to activate the option. From now on you control the cursor with the arrow keys on the number pad - the “8” moves the pointer up, the “2” down and so on. The directions of the arrows are also indicated on the keycaps.

If the keyboard does not work, but the mouse or the touchscreen on a notebook (if available) does, then an on-screen keyboard can be quickly displayed. To do this, simply click with the right mouse button on a free space in the Windows taskbar below and select "Show on-screen keyboard (button)" from the context menu. A keyboard icon will appear next to the clock and date in the lower right corner. Click on it to show the on-screen keyboard in the lower area of ​​the screen. The respective entries can now be made using the mouse. You can hide the keyboard again with a click on the X in the upper right corner.
