Not necessarily if you turn off your computer or use hibernation instead of sleep, AND you use full disk encryption. This will stop short-term attacks, like cold boot attacks and the like.
Of course, if they "borrow" your laptop for a while, opens it up, installing key loggers, modifying the firmware/hardware, and you do not notice this: you are f*ed.
I mean: even if you believe that "if someone has physical access to your computer, it's pretty much game over" you don't necessarily drop encryption and user password on the laptop and always put it in sleep mode.
