I own a Ideapad Y500 purchased in Nov-2012. It was working fine until this week and now the keyboard behaves weirdly while typing. The following things happens and it is not consistent with keystrokes. It happens 1 in 50 keystrokes. 1. while typing it adds up few more characters. 2. suddenly the browser is minimized. 3. when using chrome automatically find option is selected (Ctrl+f) and i can find "8TY][" in there. Also the capslock get's on during this. 4 suddenly while typing the cursor move the first letter and automatically types "ew-uiop". any help on this is appreciated. Thanks in advance.
