Sometime ago when I returned from long holidays, I found that the battery of my car had drained and needed recharging before it could turn the ignition. According to my car manual - and it is an expensive car - It is normal to have battery drain when the car is not in use. You would need to disconnect the cables from the battery to eliminate drain and there is a procedure for this. So if this is acceptable for a car, why not for a laptop? Please stop wining about insignificant things. SB has much more serious problems with blue screens when you undock, dock, hibernate etc.
Clearly you don't understand the significant differences in the technology between car batteries/systems and electronic devices such as the SB and SP4.
"Wining?" Really?
