Your power supply may have blown out
you need to find a tester and test power out from your power supply. If it is not same as factory specs then find a replacement and test the laptop.
If the laptop and the power adapter do not show any sign of life, this is first step to troubleshoot the problem.
When you find a replacement adapter connect it first with battery out.
In any case do the reset suggested by firs expert removing battery and connecting to adapter only.And test the adapter.
If the adapter is fine , then your laptop may be in serious troubles, most common cause is motherboard gone.
regards
I see now you have those two leds on (led on adapter and battery on laptop)
Then the problem is with the laptop.
All you can do at user level is removing the Ram modules and plugging them back. If you have two of them, plug only one at time.
Also remove cd unit and HD, and start it with only 1 RAM module, see if it load bios. If it does mount it back.
If is not that then probably the motherboard must be tested with a diagnostic board.
