My keyboard isn't connecting to the screen. physically, everything seems to be connected properly. I'm using on-screen keyboard at the moment. What should I do? How can I find out wat's wrong?

please help!

sorry, no idea. i'm not good at this stuff...

You don't connect your keyboard to the screen, no wonder it isn't working

Maybe it's broken, try another one and see if it works.....

hmm, I turned off my computer for shabbos and turned it on, now everything's working again. BH.
