Laptop repeatedly types /?

I have a Lenovo Ideapad 110 that spams / anywhere it can. The key is not stuck, and I have not spilled water on it. It's a software problem. What exactly might it be and how do I fix It?

You are likely wrong and it is a hardware issue… Specifically, the keyboard is dead.

the only possible software issue would be the keyboard driver -- that's probably a generic microsoft thing. If you can find the driver [right-click on connected devices or similar in the hardware section of the control panel] try to update it.

borrow a usb keyboard somewhere. Plug it in. In hardware, disable the built in keyboard. The connected [usb] one should still work and if the annoying issue is gone, you'll KNOW it is the hardware

I'd agree with Spock. Try substituting another keyboard.
