Wandash how do you know how much fuel was onboard? nothing has been said formally, to my knowledge.
A couple of thoughts, while they're still potentially relevant...
Northern tip of Malacca Strait to Maldives - as the crow flies ... ~1,700 miles
Supposedly, the plane was picked up by Malaysian military radar crossing over the Peninsular Malaysia into the Strait of Malacca at around 2:15 a.m.
1,700 miles (as the crow flies) would be transitted in 3.04 hours, at Typical Cruising Speed (560 mph - @ 35,000' feet)
1,700 miles (as the crow flies) would be transitted in 2.88 hours, at Maximum Speed (590 mph - @ 35,000' feet)
The spokesman for the Malaysian government said that the "Maldives" reports had nothing to do with this flight.
Maybe that is correct.
If, though, it is not correct - the witness testimony would have placed the plane in the vicinity approximately 4 hours (if there is a time-zone differential that was not factored in, this number would be off) after it was noted crossing the Peninsular Malaysia into the Strait of Malacca...
And, if the flight path was somewhat erratic, for purposes of avoiding known radar/tracking facilities - I see no reason it could not have gotten this far on the fuel available and at typical cruising speed.
This is a good read.
am a 777 pilot and have waded painfully through all these pages.
To be pedantic the 777 transponder cannot be turned off in flight from the flight deck. ie depowered with digits blank. There is no off switch, however there is a standby position which will stop it radiating. You would have to pull the circuit breaker to totally depower it. In flight on the 777 you never go to standby if you are given a change of squawk.
The suggestion of taking off with main tank fuel pumps off is not a valid possibility. The electronic checklist would not tick itself off, and there are clues on the eicas screen. If you did take off like that and the engines failed in cruise you would get low pressure fuel warnings first and your radios would still be working normally.
Goes on further about 45,000 ft altitude etc, worth a read.

TomNod just sent out emails saying they have new photos of the Indian Ocean areas and are asking those who have searched other areas to search the new photos.
The aircraft sighting in the Maldives has been dismissed by that county's government because they did not see it on their radar however it appears that the last flight departure was at 2.20am and the first arrival was just before 9am therefore the radar was turned off when this sighting was made?
How then can both the Maldives and Malaysian Governments dismiss as irrelevant this sighting?
If radar was turned off when it flew over then the Maldives government can't dismiss the sighting.
The aircraft was not behaving typically therefore you can't quote typical cruise speed or range. Economical cruise speed quoted for jet airliners is based upon parameters for gross weight and altitudes flown.
When you fly beneath 30,000ft fuel consumption rises. If MH370 was flying low over fishermen off the east coast of malaysia and also low over the Maldives, but last seen leaving the Straits of Malacca climbing at 29,500ft, then obviously it was going up and down like a porpoise and unlikely under any deliberate control.
You could quite easily knock an hour off any normal range estimates and the satellite responses atre the only guide to endurance (but not to range)
American and British aviation officials have refined satellite signals from the missing Malaysia Flight 370 and created two possible flight paths that dramatically narrow the scope of the search to an area off the coast of Australia.
The two possible paths have the plane heading toward the South Pole and ending, experts believe, off of Australia.
U.S. officials familiar with the investigation tell ABC News that the hourly satellite pings from the jet had yielded far more clues than expected, enabling the focus of the search to be cut in half - from an area roughly the size of Texas to that of Arizona.
Calculations by UK and US experts had now been handed over to the Australians to help with the search.
