I am using Synaptics Pointing DD v. 22.214.171.124 on my HCL Notebook EC2 (Model B3015) using Windows XP. Can I upgrade it to version 126.96.36.199?
If you have a Synaptics touchpad driver on your notebook then yes, you can upgrade to version 188.8.131.52. It's the same driver only that it's an updated one. It should work with your notebook.
