Keyboard acting weird

Hello,

I am having an issue with my asus laptop keyboard and it doesn't make sense to me. Looking for anyone who could help out! :)

Following issues:

• ctrl + c not working
• shift + c not working
• regular c working
• - key on numpad not working
• when logging into windows to type password on startup it keeps typing dots till I hit enter, then I can type normally..
• can't put laptop in sleep mode as it starts "typing"
• nothing is typed by itself in notepad etc (so not just a stuck key)

I am lost here what the cause could be, any advise appreciated!

Thanks in advance!
