Hi folks,
I understand the mousepads on your HP notebooks are not working. Please go ahead and start Using and Troubleshooting the TouchPad or ClickPad (Windows 8)
If you are using an older Operating system like Windows Vista or 7, go ahead and start here: Using and Configuring the TouchPad.
Please let me know if this was helpful and if you are now able to scroll using your trackpad.
Thank you in advance,
