That course — headed into the Andaman Sea and towards the Bay of Bengal in the Indian Ocean — could only have been set deliberately, either by flying the Boeing 777-200ER jet manually or by programming the auto-pilot.
The fact that the plane — if it was MH370 — had lost contact with air traffic control and was invisible to civilian radar suggested someone on board had turned off its communication systems, the first two sources said.
New electronic weapons allow jamming, blinding, deafening and more, so that a plane could possibly vanish from radar detection and security systems would not be activated. Basic radar Electronic Counter-Measure strategies used in electronic warfare (EW) are: 1) radar interference, 2) target modifications, and 3) changing electrical properties of air. [Source]

Some decent information being released now.
So far, from recent updates:
Whoever was flying it tried taking out the communications but forgot to unplug the panel so pings were still being made to Boeing /RR and course detectable by military.

It's the way I understood the explanation for it as well. Was just responding to the poster who said every piece of electronics could be disabled from the cockpit. My understanding of the equipment in question is it's a data feed for the manufacturers of various components so they can make realtime use observations of their equipment for future improvements. It's a service they pay a third party for collecting and transmitting to them.

The system that has said to be giving off the 'pings' for 4 hours is not to do with tracking but some kind of maintenance system as far as I understand it.

It is for airline maintenance, the airline didn't subscribe to it but it sends the pings anyway, hence that the airline might not have known but military and RR did.

The pings were detected by military / higher agency, RR refused to comment if it received the pings, which it probably did.
As Hishammuddin mentioned, Rolls-Royce has issued a statement denying that its engines sent out signals from the missing aircraft after it vanished from air traffic control screens.
The statement, which was also sent to the Guardian, said:
Rolls-Royce continues to provide its full support to the authorities and Malaysia Airlines. Rolls-Royce concurs with the statement made on Thursday 13 March by Malaysia’s transport minister, Hishammuddin Hussein, regarding engine health monitoring data received from the aircraft.
I have no real knowledge of the workings of any plane much less a sophisticated 777, but yeah I would guess that system is self-contained and cannot be disabled by flight personnel.

So I would think it's not something you could disable?
No one wants to address this?

How come it's been fully overlooked that this occurred on the anniversary of a similar hijacking of another flight heading to Beijing? No one believes there can be a connection? Really? On a conspiracy site?
My understanding is there is no "off-switch" but that it could be disabled by removing a fuse. One speculation is if someone turned off what they knew how to turn off, but they didn't pull the fuse on the satellite link communication, because they didn't know about it/didn't know how, but this is just regurgitating what someone else posted, not sure of its accuracy. Sounds plausible though.

That sounds like what was explained by the "expert" on CNN.

Satellites picked up faint electronic pulses from the aircraft after it went missing on Saturday, but the signals gave no information about where the jet was heading and little else about its fate, two sources close to the investigation said on Thursday.
But the "pings" indicated its maintenance troubleshooting systems were switched on and ready to communicate with satellites, showing the aircraft was at least capable of communicating after losing touch with air traffic controllers.
The system transmits such pings about once an hour, according to the sources, who said five or six were heard. However, the pings alone are not proof that the plane was in the air or on the ground, the sources said.
