I have a problem with new Sony Vaio e14 laptop that I just recently brought. My mouse pad on my laptop doesn’t work very well, it kinda disable itself when i press down a key on my keyboard. Some of them it does work but most of them it doesn’t. It takes about ½sec from i press a button till it stops moving on my screen. It does work with perfectly fine with my USB Mouse. The reason to I really want to get this problem solved is because I find it very annoying while playing games e.g. Counter strike, Minecraft, Battlefield, browser game and lots of other games. I have made a picture with a very similar computer just a different model but it have the same keys. All the green keys do work with my mouse pad and all the red keys don’t.

I have brought a Sony Vaio sve14a1c5e a month ago, and i have a few problems with my mouse-pad. When i played a game by using my mouse-pad, but that wasn't easy because when i moved around using the WASD keys my mouse-pad didn't respond at all. So i figured out when i hold 2 buttons down from my keyboard then my mouse-pad wont respond at all. my USB mouse does work perfectly fine so it doesn't affect that, but does anyone know whats wrong and what can i do? Thanks for your time =)
