Hi Fighterahmad,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP Pavilion g4 and the Touchpad working slow. Click the Start button , type "device manager" in the search box, and then click Device Manager. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
In the list of hardware categories, find the device that you want to update, and then double-click the device name.
Click the Driver tab, click Update Driver, and then follow the instructions.
Please let me know if this helps.
Thanks.
