[Mico]

i never open my facebook account from any other pc , just my laptop , so if any body for example open my facebook account on another pc i will get a notification ?

I don't believe you receive a notification. It just logs you in like your on a different computer. Just in-case, I would suggest that you don't share your information.

I always get an email when I do that, so I think you would too.

not necessarily..
you could go to your account settings, choose security, then click on "Active sessions"
it will show what devices (and where) have access to your account..
