asus power issues

[Steven61171]

Hi I have an old first asus rog laptop g2p and I love it playing the old games on , but all of a sudden it wont boot the battery light flashes orange intermittently and the fan also goes on and off the same as the light . I also noticed with the light off in the room , that the backlight on the screen faintly lights up otherwise its a black screen.
I have tried changing the bios battery and reset it both shorting the contacts and by holding the power button down .
But what I failed to mention was this is only when I insert the power supply and nothing happens when I press the power button it is dead apart from what I have mentioned please anybody help if you can.

Sounds like the motherboard is dead.
