Almost every model of Lenovo laptops has accelerometer, it used in Airbag protection and Reading optimization prog.
I suggest to Vintage programmers to make another new app that uses the data from accelerometer and will be responsible for security in the way like this:
1. Somebody try to move a laptop2. The app receives the data from accelerometer and immediately block (turn off/ hibernate/ - user decide which option is suitable)
Of cause the option to choose sensitivity is also necessary
Thanks and sorry for my English
