VGN-N38E touchpad u/s after Windows 7 install - please help

[petrobe41]

Hi All

Can anyone help?

Yesterday I did a clean install of Windows 7 on my VGN-N38E.  Everything was working great. Powered up this morning and my touchpad and keyboard would not work, restarted machine then the keyboard started working but the touchpad wont.

I have tried uninstalling and re-installing.

Tried updating driver.

Tried booting in safe-mode, deleting entries in registry, deleting all record of Alps software, uninstalled Apoint.

NOTHING i have tried has worked.

When I look in device manager it doesn't even show up, all that shows is the USB mouse I have had to start using.

Does anyone have any ideas?? Its driving me mad!

Try to visit the website of the touchpad provider that came pre installed in this notebook. Try to download and install the driver form their site too.

Please update us on how this goes.

Hi petrobe41,

Is there anything showing in Device Manager as ‘Unknown Device’? If so update the driver following the ‘Have Disk’ instructions below.

If nothing is showing at all, as a last resort, uninstall all devices listed under ‘Universal Serial Bus controllers’ and then shut down.

Remove the AC power adaptor and battery and then hold down the power button for 30 seconds.

Re-attach the AC adaptor and battery, re-boot and let Windows reinstall the drivers.

If at that stage you have an unknown USB device listed in Device Manager then update the driver using the original Vista Pointing Device driver that can be found in the original drivers folder (Pointing sub-folder).

You will need to use the ‘Have Disk’ method.

Extract the files from the installation package to a known location.

Click Start > Control Panel.

Double click Device Manager.

Right click the device and select Properties

Click the Driver tab.

Click Update Driver.

Click Browse my computer for driver software.

Click Let me pick from a list...

Click Have Disk....

Click Browse and navigate to the folder where you placed the extracted files.

Click OK.

Click Next.

Click Finish.

Reboot your system if requested.
