What To Do If The Keyboard Has Stopped Working
There is no feeling of greater impotence when the computer keyboard suddenly stops working. While many of the functions on a PC can be carried out only with the mouse, a keyboard is a necessary element to carry out the real work and make things simple but critical such as starting at the desktop account. If the keyboard stops working, there could be several reasons, depending on the type of computer you have or the type of keyboard.
Wireless Keyboards Often Fail
Wireless keyboards actually tend to fail. They depend on a battery and when that battery runs out, the keyboard dies. Wireless keyboards are known to “eat” or drain the batteries very quickly. Have a set of new batteries nearby to revive the wireless keyboard when it fails. The wireless keyboards communicate with the computer through a small transmitter on the keyboard itself and a USB receiver connected to the computer. If the connection between the two devices is not good, the signal is blocked and the keyboard does not work. Replacing the USB receiver can be difficult, as some wireless keypad manufacturers sell the USB receiver separately. Have a wired keyboard ready as a backup in case your wireless model fails at the wrong time.
Common Laptop Keyboard Failures
The keyboards of the laptop are robust but tend to fail for electrical reasons. When this happens, you usually have to replace the entire keyboard. Spare keyboards for most brands and models of laptops are available on the Internet. The replacement of a keyboard is the easiest repair that you can achieve for yourself alone since you can change most of the keyboards without disarming the computer. You can find instructions for removing and replacing the keyboard in the manufacturer’s manuals. Laptop keyboards fail, mainly, when exposed to liquids. Spilling a chocolate martini on your keyboard, for example, short-circuits delicate electronic parts, in the worst case; in the best case, it causes the “springs” to fail under the keys when the liquid crystallizes. Damage caused by liquids means replacing the keyboard.
PC Keyboards Fail Less Frequently
Keyboards wired to the computer come in two types: PS / 2 and USB. Most failures of any kind occur when the plug simply comes loose from the back of the machine. Reconnect the keyboard firmly and the problem is usually solved. The tiny wires inside a PS / 2 keyboard connector can become bent or broken. Examine the inside of the PS / 2 plug. If the wires are bent, take a nail file or a small screwdriver and carefully pull the wires back into a straight up and down position. If the tiny wires inside the connector are broken, replace the keyboard with another PS / 2 model. USB keyboards have the best performance record, but they can malfunction if the USB port itself is dead or malfunctioning. Test your USB ports with other USB devices to determine if the problem is the keyboard or the USB port. You may have to reinstall the USB port drivers to restore the function of everything, including your keyboard.
Problems Caused By The Software
Some legitimate viruses and software can also cause a keyboard to crash. Restart the computer and press F8 to start the computer in safe mode. If the keyboard works in safe mode but does not work in normal mode, there is likely to be a conflict over viruses or software. Analyze your team of possible infections. Uninstall any new software. If the keyboard works with the new uninstalled program, there is a problem. Contact the software manufacturer for help in resolving this conflict.
