Why does my computer spaz out so much even when I don't touch it?

It's a Lenovo and I've heard their computers are bad. Examples are when I type 's' or 'w', it types out a whole row of letters instead of the one I wanted. Another example is when I tilt back my screen, the light settings pop up and mute my music. Can anyone help?

Think… There's something obviously wrong with your computer. If its a keyboard issue there's a chance its related by hardware 90% and depending how old y our computer is. Gotta add the pos factor it.

Since my question is kinda half @ss its only due to the limited amount of information you have supplied us in the answer…

I have an L V570, 2 yrs old, that I don't like that much, but haven't had the probs you post.

see if there's a keyboard sensitivity setting. My settings are accessed via the Synaptics icon in the system tray near the clock.

look in control panel for other poss settings.

see if your still under warranty, & google the probs w/ you model code & search for recalls.
