I started a windows update for my windows 10 laptop at 10:45pm. It's now 11:52pm and it's stuck on a black screen with the little loading circle at the bottom. I can't check the hard drive activity because for some reason, the Fn-H hotkey to toggle the LED from battery status to HDD status does nothing. I hate leaving my computer overnight like this, but I'm gonna do it and I'll let you know what it's doing in the morning. I'll probably force it to shut down if it's still doing this in the morning.
