If your question is: do you show up as actively logged on, then no. If there's no activity for a few minutes, your username drops out of the active users list.
This is what I meant to ask. Thanks.
If you're asking whether someone else can use your account, then yes, if they turn your laptop "awake", they would be able to come here as your account and do everything you can do.
If your laptop is around other people, I'd suggest logging out, or setting it up to require a password to log on once it's brought out of sleep mode.
Laptop always stays at the house and everyone has their own laptop. Also, my family is fully aware of heresy so no worries.
