Left mouse button on VGN-AR requires a lot of pressure to operate
The left mouse button (not the touchpad) on my Vaio VGN-AR51M still has the same travel and movement as it did when I bought it a year ago, and the same satisfying 'click' when pressed, however the button seldomactually works as it should do, clicking and dragging being the most irritating function, as it will frequently lose contact halfway through, or sometimes it will double or triple-click when I am trying to single click, and often requires a lot more pressure to function at all than it did when I bought it.
I use an external mouse when I can, and am not looking forward to sending my laptop back for repairs, as I require it on a daily basis. But ultimately, I would like to figure out what the problem is so I can fix it.
The mouse buttons are housed along the edge of the laptop, which makes them difficult to access, and I have not resorted to taking the case apart to see how they function yet. I dearly love my laptop, and this so far is the single only problem I have had.
Any guidance or assistance would be appreciated.

Re: Left mouse button on VGN-AR requires a lot of...
On your model the buttons that you press on your mousepad are actual tactile buttons that are on the motherboard and they do wear out over time. The only way to resolve that problem would be to either bring it to a electronics shop where they can replace the tactile button on the motherboard or replace the whole motherboard itself which could get pricey.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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 .
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.
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.
