I solved my problem by sticking a piece of cardboard just beneath the motherboard, don't worry if it causes the motherboard to bend upwards a little. Its been working very well for the past couple hours straight. I explain it a little in this video.
This works if you find yourself pressing down on some spots on the laptop/chassis/mobo just to get it to power up. This method also repaired my old IPOD when it was having trouble with its PCB.

I don't have a solution, but the same thing happened to my model (identical brand). You would think they are set to glitch at the same time!
I am going to take it to a technician, as I have not dabbled in computer hardware much.
Your post was really helpful though.

Sure sounds like powerline troubles. Be aware that fixing these kinds of problems are risky, so be careful and know you might trash it by accident by following the suggestions below.
Remove the battery completely throughout all testing.
First check and make sure the powerpack is outputting the right voltage, if not, you have a bad power supply. If that's okay, and you can get it to boot up at all, trying twisting the body of the laptop lightly, jus a little, diagonally. If the laptop shuts down or locks up, you have a motherboard problem or bad cabling somewhere.
My opinion only: from the description it sounds like you have a power short on the motherboard where it contacts some part of the case. Try removing all screws on the underside of the case and rebooting. If this does not work, unplug it and try to loosen the motherboard mounts slightly by removing the retaining screws and the ones that hold the keyboard assembly in. Then try to start it up again. I would guess that at some point it will start up and work normally, and from there you need to try to identify where the problem is. I have fixed this type of problem before by lightly insulating the separate component boards from eachother and the case contacts with spacers made of double sided foam sticky tape, and reassembling. This is just a guess, but was what went wrong with my Toshiba Portege.
PS: If the laptop has any add-in cards like a network card, remove them before testing
