How do I repair my laptop's touchpad?

I have an hp laptop, it's relatively new, doesn't have any issues. I connected an external mouse and a wacom tablet, it worked just fine, but when I disconnected everything and tried to go back to normal the touchpad doesn't work, like the arrow just disappears if the tablet or external mouse aren't connected. I've searched on the internet but I don't know what to do
