Remove your battery and try with external power supply again if it boots up all good and proper then after booting to SOE refitt the battery and let it charge - if it doesn't boot or power on look to see if the blue LED it on around your power input point. If there is no illumination around the power input port try another 65w power supply input - your power pack may be dead. Cheap fix - if it still does the same powers on then off - you have reason to go out and buy a new laptop - would be cheaper than replacing the M/board
trust me.
