Recently, every time I put my Sony Vaio (Model VPCEB3F4E) to sleep or turn it off, when I turn it back on the trackpad does not work correctly. It only goes vertically, not horizontally, and after a few minutes it stops going vertically as well. This problem continues in Safe Mode. The trackpad is turned on, but it just simply will not work. Does anyone have any idea what the problem is?
