i have a extremely wierd problem with my laptop. while i am typing, some key(in my case its 'd') gets typed continuously without typing it and this stops only when i press that key itself. this some key can be any key on the keyboard. due to this i am facing lot of problems as for e.g. sometimes some appl. automatically get opened up, windows narrator on my laptop. some months ago instead of 'd', 'u' was having problem and before that '5' was having the problem. so the problem is not with some specific key, it changes i dont know how. also when there is problem taking place then i cannot click with my touchpad and i can click only with button below. i dont know what to do. due to this problems when i click on my window key, sometimes my laptop automatically gets shut down. these problems only take place sometimes and at other times it works prefectly ok. i hope someone can help me out.
