I am using Synaptics Pointing DD v. 18.104.22.168 on my HCL Notebook EC2 (Model B3015) using Windows XP. Can I upgrade it to version 22.214.171.124?
If you have a Synaptics touchpad driver on your notebook then yes, you can upgrade to version 126.96.36.199. It's the same driver only that it's an updated one. It should work with your notebook.
