It's been happening for a couple of days, but my laptop won't shut down or restart, it always says I'll lose work and asks to shut down anyway.

Even though I still click shut down, it doesn't.

Also, I can't turn the lock screen on. It won't work when I click Windows Key+L, which I manually have to do. My photos app doesn't work as well and also the Fn key won't work when I try to adjust the brightness but it works for sound.

Any ideas why & how to fix this?

Have you tried forcing it off (hold the power button for 3-5 seconds)? –  Ƭᴇcʜιᴇ007 Oct 6 '13 at 16:38
    
that worked thanks, thought it'd be something more complex but it just had to update more things ;~; my fn key still doesn't adjust my brightness though :l –  kathy cee Oct 7 '13 at 2:59
