I am using Synaptics Pointing DD v. 8.3.5.25 on my HCL Notebook EC2 (Model B3015) using Windows XP. Can I upgrade it to version 12.2.11.19?
If you have a Synaptics touchpad driver on your notebook then yes, you can upgrade to version 12.2.11.19. It's the same driver only that it's an updated one. It should work with your notebook.
