This theory has been discounted as why would that involve the transponder being turned off at the same time. I suppose its possible to "knock it" grabbing for a mask or during a violent move of the plane or something...
No, it has not been discounted. Little has been discounted at this point aside from MAS370 safely landing at PEK
. There are several ways a transponder could be disabled aside from someone setting it to STBY.

Perhaps ACARS is simply less obvious to the other pilot? Perhaps you can turn off ACARS without your fellow pilot noticing?
No, there isn't an "ACARS switch" on the flight deck one can casually flip with some sleight of hand. To sabotage the system would require opening the main deck access panel and taking a trip down to the E/E bay.
Mind you, ACARS is a system which several pieces of equipment use to send data out. EHM (diagnostic data from the engines) is one example. Weather report requests are another.

They are saying ACARS(Data Reporting System) went down @1:07AM and Transponders @1:21AM.
If this is accurate - and that's a big if - then it would stand to reason that this wasn't an act of sabotage. Otherwise, someone went down into the E/E bay and disabled ACARS, then they shut off the transponder 14 minutes later. Doesn't add up.

Someone made a passing comment about the private jet of a golfer crashing where everyone, including both pilots, passed out and died and the jet simply crashed. Could this happen?
It did happen. Payne Stewart was the golfer. He was in a private jet. Also happened to Helios 522, a 737.
