Laptop not starting up

[Esparko2]

I have an asus u45jc, had it for several months but now it's not starting up.

Theres nothing showing up on the display
The CPU fan is still turning on and off so it seems like it's still working on something
The num lock and caps lock lights are stuck on which never really happens

It's still under warranty but I don't want to lose the work I have on it.
Does Anyone have a clue on how to boot it up?
Nothing on the screen at all.

could try taking the battery off completely see if that helps

Yeah I've done that. Switching the battery in and out.
Before hand, I actually used the laptop without the battery most of the time because it just stayed in my dorm for most of the week.
So it just ran straight from the plug.

Edit: I think it's a major hardware failure cause I just noticed it makes 4 subtle beeps. Only once, doesn't repeat. But I read that it meant it was the bios or the motherboard or something critical..

open chassis.

strip the laptop.

power each component connected to the mobo one at a time with/without the battery.

worst case scenario is the mobo is dead/bad.

-in which case if the repair is beyond your liking, back up data, then liquidate the parts.
