What an unexpected problem worse and absurd. Happily sit at the computer and suddenly find that we can not write or play because the keyboard incomprehensible decided to take a break.
The problems with the keyboard are two types of solution: either very simple or none. In the first case, we let some aid.
When there appears to be a simple solution, the best advice you can give is: buy another! Perhaps the cable has broken and not worth wasting time on it. They do not usually break followed, but the keyboards are easily replaceable, accessible, and affordable prices and reliable.
1) Check cable
Let us start from the base. A normal keyboard with cable, connecting either USB or PS / 2 . The first and obvious, connect and disconnect the cable, check that has not been moved or folded.The cables are a pain to have to live yet (how long?), Tend to break easily, as well as gather dust and become entangled in surprising ways art.Yes, the cables are our nearest main technological enemy. But remember the old adage: "Keep your friends close, but even closer to your enemies."
Take good care of those devilish cables, which do not bend, do not repeatedly connect and disconnect the keyboard or mouse. Not show it to your pet , usually nibble those delicious jelly beans that cover it. If cables have to live with, treat them with respect they do not deserve.
2) Check the batteries (wireless)
Someone may think for a moment that earned the system by becoming a wireless keyboard. Poor deluded. Just change the name of our enemy, and now is a more expensive and polluting: the batteries. The wireless keyboard batteries often run faster than what the sellers told us to go. The worst of the story is that a wireless keyboard is running out of battery takes to stop working altogether.
It is a slow and painful death in which at times we have the illusion that all goes well, then find that we can not turn right while playing, or you have written anything to our friend's chat. Then, change or recharge batteries.
3) Check the connection port
All right. The cables and batteries are to blame for everything. Sometimes the walk is not the port that are connected. There are basically two ways to connect a keyboard: the classic PS / 2 (circular connector with 6 pins, usually purple), and the popular USB. Both can be damaged more easily than we expected.
Test switch connector to see if that's what is going wrong, computers usually have at least two ports of each type.
