We got some new Dell Laptops at work and they are configured to power on when you open the lid. There is a fingerprint sensor that I think is maybe supposed to be a power button, but it doesn't seem to work as a power button. Twice now the laptops have locked up (black screen, keyboard doesn't light up, etc...) and the old trick of holding the power button down for 10 seconds to hard power it off doesn't work. You have to disassemble the thing and unplug the batteries to get it to power off. Then it powers back on when you plug it back in and open the lid.
