Maybe Windows, I haven't used it in a long time. But I have noticed my son's MacBook pro (used to be my work laptop) only pretends to be available after "waking". It'll repeatedly fail to actually take input in the user login password field. It does so silently, leading to missing characters in the password and needs several attempts to actually fill out fully. I don't know what it's doing in this time, but not having the "busy beachball" is a lie.
