but don't you need the battery? how do you gonna hide the battery? the moment the detected it, you lappy should be exposed. though, i had seen many cases lappies are being stolen from gym changing room.

my advise to you is not to bring your lappy to the gym center. i have heard of cases lappies got stolen on and off. now that my gym centre recruited a security guard patroning the changing room. but, how much could that helps? leave it in your office if it's nearby gym centre. sigh, now i start to worry about my pda phone...
