TOUCH PAD NOT WORKING
The Sony Vaio laptop is typically sold with a touchpad device installed below the keyboard. The touchpad is for navigating the screen and is used like an external mouse. A touchpad can sometimes malfunction for no apparent reason, but there are ways on troubleshooting the device yourself before asking a technician for help. Start your computer as you normally would. Click the "My Computer" icon on your desktop. Go to "C:\ Program Files\Sony\Setting Utility Series." Find and choose the "VCCPointingDevice" folder in the "Setting Utilities Series folder" to open the "Built-in Pointing Device" dialog box. Locate the "Enable" box on the "Built-in Pointing Device" dialog box. Check the box to enable the Vaio touchpad if you wish to use this device. Disable the touchpad if it is interfering with the external mouse. Uncheck the "Enable" box if you have a USB (PS/2) mouse connecting to your Vaio and wish to use that instead of the built-in touchpad. Pick "Yes, I'm Sure" when prompted to activate your choice, then close all the windows. Windows 7 Normal Mode Launch Windows as usual. Go to "Start" > "Control Panel" > "Mouse" > "Pointing Device" to open the Vaio touchpad control center. Uncheck the "Enable" box on the "Pointing Device" window when you wish to use your external mouse. Check the "Enable" box on the "Pointing Device" window when you want to use the Sony Vaio touchpad. Make sure the external mouse is not interfering with the touchpad if you have one connected. If so, unplug the mouse from your computer. Click the "OK" button at the bottom of the "Pointing Device" window. Close all other windows. b> XP and Vista Safe Mode b> Restart your computer. Press the F8 key before the Windows welcome screen appears to enter Safe Mode. Click "Start" > "Control Panel" > "Add/Remove Programs." Find and delete all software for mice and pointing devices. Restart your computer in normal Windows mode. Proceed to next step if the problem persists. Restart your computer in Safe Mode. Right click the "My Computer" icon on the desktop. Choose "Properties" on the drop-down list. Pick the "Device Manager" tab in the Properties window. Select the "Other Devices" folder and click on the "+" sign besides it. Delete all the devices under this "+" sign by clicking on the "Remove" button next to each of the items. Restart Windows in Normal Mode. Once Windows is operating, there will be a "New Hardware Wizard" pop-up that will load all the necessary drivers for the touchpad, mouse and other pointing devices. This should fix the corrupt driver for your Vaio touchpad. b> Windows 7 Safe Mode b> Reboot your computer and press the F8 key before the Windows welcome screen appears to enter Safe Mode. Go to "Start" > "Control Panel" > "Device Manager" > "Mice and other pointing devices." Click the touchpad icon. Choose the "Driver" tab and press the "Uninstall" button. Press the "OK" button to confirm. Restart Windows in Normal Mode. Go to "Start" > "Control Panel" > "Device Manager" > "Mice and other pointing devices." Choose the "Driver" tab and press the "Update" button. Press the "OK" button to fix the touchpad software. Hope this help.
