My little cousin kept hitting all the buttons on my Lenovo laptop she kept messing round with it all day and now she broke my mouse

It won't move no matter what I googled it and it said hold down FN and the F6 button I've tried all this and won't work? How do I turn on the mouse again without having to move the mouse?

Did you restart the laptop?

Nevermind everyone, she turned it off by hitting random buttons so all I did was swiped my hand over every single key and it just worked haha, thank you anyways tho.

Push and hold the power button until it dies if it's Windows 7 push the f8 key and get into the repair my computer console and use a system restore point to go back a day before your cousin played with all the keys that will fix your mouse if it's Windows 8 or Windows 10 turn your computer off and on off and on off and on several times in a row until the automatic recovery console starts when you get into the automatic recovery console find system restore not system reset and again go back a day or so before the event happened

And what have you learned from this little exercise?
