How do I stop my sister from using my laptop?

Many good answers above.. ( +1 thumbs up for all!)

(note - mac doesn't have facial recognition locked up.. my Alienware with Win 7 also has it)

1) Password protect the operating system - all user accounts.
( of course, older Windows machines this won't help)

2) Add a BIOS password - so when the machine boots up, it cannot even read the hard drive unless you put in a password. Don't make it too easy.

3) take battery, AC power adapter, and anything else you can - hide them in different places or take them with you.

4) get a small screwdriver, and remove the hard disk. Pretty easy to do, just check the instructions from mfr. website.

5) spring for $8 and get a kensington lock - chain it to your bed frame or closet rod.

6) spring for $25, and get a kensington lock with a 125 decibel alarm (heh!)

7) steal all your sister's black pens. (no more ink marks)

8) go to the basement / utility room, and turn off the power breakers to your sister's room.

9) install a keylogger on your computer, then after sister uses computer - embarrass her by logging in to Facebook / myspace/ unicorn world/ whatever.. and make weird comments. Maybe just change her account passwords so she can't use the computer for anything. She is your sister.. so don't do anything really weird or insulting to her friends.

10) make a mold of your computer, fill it with concrete. After it cures, smooth it down and paint the outside so it looks kinda like yours. Leave the "decoy' where sister can find it, while you find a good hiding place for your machine.
