Macbook pro won't start

Hi!

I have a 2009 era Macbook pro. After I connect it to the power (the green light is lit up) and then press the power on button, the laptop does not power up. I tried long press, short press, nothing works. No lights light up on the laptop when i press the power button, and there is no startup music or anything like that. This is the same whether I am starting with a battery or without a battery.

As background info, I would like to add this; my laptop had the 'warping' battery issue; the battery became so warped, it was physically impossible to place it on a table. At that point I took it to Apple service, and they advised me to take out the battery and use without a battery till i purchased a replacement battery. At that time, and for a few days more, the laptop worked fine, without battery when connected to mains power. Then a few days later, it just wouldn't start. Thinking a new battery would solve the problem, I purchased a battery. Sadly, and as described above, the laptop does not power up, with or without the battery.

Any ideas and suggestions, will be much appreciated!

Thanks Acorn; I tried this:

Resetting the System Management Controller (SMC)
Resetting the SMC on Mac portables with a battery you can remove

Note: Learn about removing the battery on MacBook and MacBook Pro.
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.

DIDN'T WORK!

So I tried this:

Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

DIDN'T WORK!

I think perhaps the above are for computers to which there is some power supply; mine seems to be dead altogether.

Any suggestions will be deeply appreciated!

Anyone?
