i have actually seen 2 ppl go thru a car park in a car @ Jln Pekeliling n rounding around with their laptop as they r scannin each and every car.i doubt the scanner exist, pda, and phone have clock and bios also.. and all are the same crystal used.
I have a friend use a notebook bag and put books in the car boot, after coming back from dinner his boot was forced open and the bag was stolen.
I always advice all the notebook users never put the notebook in your car even for 1mins.
weikee...try u park ur car @ the pekeliling car near the DBKL n c how...i have put an old p3 notebook under my car seat last time.. used it to record ecu data.. dos OS.. and its been there for many months and no problem. so I really doubt such a things exist.
