Caps Lock Stuck and Safe Boot?

Randomly in mind typing of a paper, my Mid 2012 MacBook Pro started typing in all caps. I then restarted the computer and it booted to safe mode.

While trying to figure out what was going on in Safe Boot, it then randomly switched back to lower-case and finally allowed to boot regularly. Now its typing in all caps yet again.

I read something about spillage causes this but I know for a fact there was nothing around the computer liquid as I was in my college student union.

Any ideas as to what this could be?

Try turning off the caps lock key. System Preferences > Keyboard > Modifier Keys, set Caps Lock Key to No Action; see if that stops it.

If it starts acting up again I am going to try that. As of right now it is working again though.. I don't know seems weird to me. I think I may visit the Apple Store tomorrow.

BTW, if it forced you into Safe Mode, it's not the Caps Lock key that was at fault, but one of the Shift keys. It's possible to take them off and look underneath, but only if you have some experience working with small connections like that.

Yes, safe mode is shift key.

If you don't feel comfortable taking the keys out and cleaning under them yourself you can take it in to an apple store and they will do it for you.

In the meantime, if you hold opt while booting and boot into the restore partition you can set a firmware password...for some reason if your firmware is password locked you can't boot in safemode.
