Keyboard stop working

[Johannessss]

Hi, my problem is as follows. Different numbers on the keyboard has stopped working, at first there was just "h". But when I got back from work the other day "t "space" "c"6""7""g""v" also wouldn't work. This started happening after i got a different adapter to the computer, its a laptop. This adapter has between 17 to 21 volts and the computer has 19 volts. I went to the place where i bought the adapter before all this happened to see if it would work with my computer. They told me it would... and it does.

 My question is, how can i get my keyboard to work again?   

I'm using windows 7

Hello Johannessss!

I personally would get rid of the adapter and try a new one. Plus if your adapter is 17-21 volts and your computer only has 19, this is probably the reason why. If there isnt enough power to the adapter things will just not work.. I suggest getting a adapter with a lower Voltage intake.

if your adapter is 17-21 volts and your computer only has 19

That is a completely useless answer. The same weaknesses in English, arithmetic and basic electricity seem to be shared by the OP and the first responder. Plus those German sounding screen names are a bit fishy...  19 volts required by the computer is within the power adapters' allowed range of 17 to 21 volts and is thus OK. Also the power supply gives electricity and the computer takes it. The repetition of these errors in both posts makes me wonder whether Johannes and DamianLohrenz are the same person.

Salmon Trout , I do not want to start a flame war or anything like that, but Johannes is a Latin name , occurring most frequently in Estonia, Denmark, and Iceland. Secondly, Johannes can you tell us more about the "adapter" that caused the problem. There might be a manual voltage control that had been set incorrectly.
