It sounds like it might just be a case of the button being stuck. The ESC shouldn't turn on just from you plugging in the battery, you're supposed to have to press the button once the battery's connected to power up the ESC.
Unplug the power cord. Remove the battery. Press and hold the power button for 60 seconds then release. Plug the power cord back in but leave the battery out and try to turn it on now. If it comes on you can put your battery back in. If it still does not come on you may need a new power supply/ adapter.

To check these, remove the laptops power cord and battery, then locate and remove, the cover for the RAM.
Remove one chip at a time and try booting the laptop.
Definitely try without the battery. These models are known to have a "short" problem, usually with the palm rest, which causes this failure, although it usually is more sporatic, and doesn't happen 100% of the time.
Also, can you remove all but 1 piece of memory.
Good luck, and let us know what happens.
