mcdevito75 here, Bring laptop to Staples, Best buy for testing, sounds like that key could be hanging up. maybe some sort of oil needed.

go to services and support and download the mouse drivers

try it with toggle keys it may be work

Common hardware problem. The correct solution is a replacement tracker pad and mouse, however you may be able to get the problem fixed by cleaning under the pad. Either way it requires taking the laptop apart.

I had the same problem . The micro switch needs to be replaced . All push button micro switches have a certain amount of "clicks" before they loose ability to make a good contact . Your left click switch has exceeded its life and can no longer make a clean contact without more pressure . Eventually the spring in the switch will fail thus stick permanantly.You will have to take it to an authorized Sony Service center or maybe an office machine service department might have the replacment . I fixed my own with an old mouse microswitch .Hey it's a Cheap laptop and uses cheap parts.

My Vaio touchpad started behaving strange. I could move the curser, but no response on left or right click or double tap. Also found that in any search field or user name fields, the computer would just type endless 9's. My wireless mouse could operate the left and right click buttons, but not move the curser. A suggestion to get the mousepad operating again was to touch any key on the keyboard. This allowed it to function again. Final solution was to remove the battery, then hold down the start key for about a minute, reinsert the battery and start it up. It seems to have resolved the problem. I have a 3 month only laptop with Windows 7 already installed. Hope this helps.
