Go into the device manager and see if the driver is enabled. control panel/ system/ hardware tab/device manager/pointing devices, and see if the driver is loaded. If it is try update driver.

Do you see the lines if you connect to a external monitor? If so, your Graphics Adapter my be going. If you boot to Safe Mode , do you see the lines? Have you done ANY Updates? Upgrades? Damage?
First thought is look at the top of the touch pad, there is a button. Push this button once and see if the mouse works. HP put this button on to deactivate the mouse if needed.
If this does not work, plug in an external mouse and see if it works, if not do a hard boot on the computer and try the mouse again.
there is a switch nearby that orange light or the light may be a switch. press on it then the color of light will change and ur problem will be solve....thats all
