The first thing I would do is:
.. With battery removed and Not connected to AC adaptor.
.. Remove the HDD.
.. Plug ac adaptor into laptop and
.. power on. This should at least come up with a error message saying "need a bootable source.

If you do no get this message you have two choices:
A) The AC adaptr is Dead, or
B) the laptop MB has a problem and your options are:
.. Take it to a repair shop or
.. obtain a replacement AC adaptor and tring it with a new one - that doesn't work then it is the MB

NOTE: you can test the AC adaptor, but requires a Voltmeter. You plug it in and see if you are getting the correct voltage (Normally will read higher than what is stated on the adaptor (ie DC out = 19 Volts at 4+ Amps.
