Keyboard acting wierdly : Virus or Hardware issue?
I'm using HP Pavilion laptop with Windows 7 Ultimate running on it. Problem is:
- Enter key on the keyboard doesn't seem to work
- This problem is strange, It may sound wierd but let me see how to put in a better way. Keys on my keypad can be categorized into two categories:
Category a. Keys which activate Enter : Home row keys except G,H {i.e. asdf;lkj} fit into this category
Category b. Keys which don't activate Enter : All keys except above doesn't.
So, what happens is when ever I hit any of the category a keys, it activates enterkey (doesn't mean Enter starts working but there will be automatic, continuous striking of enterkey until interrupted by a key from category b.
Example in a notepad if you just type letter a then it will automatically followed by too many \r\n until a key from category b is typed.
I'm typing this question, by using on screen keyboard (osk.exe) for category a keys. I hope you understood the situation.
Well my question is:
Is it virus? or Keyboard Problem? or Motherboard Problem? What exactly is causing it? How to rectify it?
There's a circuit board underneath the keys of your keyboard:
The problems you describe are classical symptoms of a short circuit in the circuit board.
Besides having the circuit board cleaned by a professional (dust, spilled liquids, etc.), the only fix is to replace the circuit board or the entire keyboard.
