Asus power on and nothing

[TGSP032]

Wondering if there is a solution or if the laptop is pooched.

Asus X55A laptop -> When turned on it makes all the correct noises and the power and numlock lights come on, hdd lights flashes a few times on powerup then goes dark. Nothing else responds. Screen blank, (Caps / Numlock have no affect on the corresponding lights)

Addition info : Can feel airflow from the vents so the fans are going, CD drive does the usual startup spin up/down. Charging light + Mains power lights come on when mains power is plugged in

Have currently tried (in the following order) :
1) Unplugging power + reseated Battery - no change
2) Plugged in a monitor - no signal
3) Unplugging power + Battery, holding power button down for 30s / 45s / 1min / >1min ; replaced battery - no change (also tried pressing power 10 times hold on the 11th, and using mains power)
4) unplugged mains + battery, Removed ram, replaced battery - no change + no mem error beeps.
5) Powered up with speakers plugged in - No beeps

Hi,

Here are some troubleshooting steps that may help in solving the issue.

Start with a hard reboot, unplug it's AC adapter then press and hold the power button for 20 seconds then try booting it.
- If it doesn't work reseat the RAM, remove them all for couple of second then put them back in making sure everything is seated properly.
- Again if these doesn't work but you can hear the laptop on but with no display, connect an external monitor and see if it would display anything because if it does that means it's the built in display that is faulty.
- Next to try is if your AC adapter is still okay by trying another AC adapter that has the same voltage and see if it would work.
- If all these will not work then the problem is with the motherboard.
- Do contact Asus if it's still under the factory warranty.
