My desktop computer has a big plaster stuck to the front. It doesn’t look the greatest, but it serves a purpose.
Namely to stop the blinking lights driving me mad at night. Hardware builders have a thing for blinking lights. That’s great, but my desktop is in my bedroom (shared house) and so it’s either shutdown completely, or leave it asleep but with blinking lights.
Several of my external hard drives do the same thing when the computer is off.
There’s got to be a better way to announce you’re sleeping than a constantly flashing white/blue light.
