Hi,
Please do try these troubleshooting steps that may help.
- First, make sure to disconnect all the cables and drivers connected to the laptop.
- Start by doing a hard reboot, unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- Next is to try a different AC adapter that has the same voltage and see if it will boot up or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.
- If the laptop is still under the factory warranty, do contact ASUS for a repair.

You, Sir, are a saviour.
SOLVED!
I am so happy that I fixed my computer so I really wanted to share with everyone my method!
I have a Asus Zenbook UX303LN laptop that did not turn on all of a sudden for no reason. The power adapter & battery were working and the power light turned on, but the fan/CPU/hard drive did not so the computer did not boot up at all. I tried all the methods I found online [up to the point I was considering doing a motherboard reflow myself] UNTIL a computer friend told me this:
1. First unplug and take out the battery. Please the power key for ten seconds then plug in power adapter and try turning it on
2. If it doesn't work, then unplug again, and reseat the RAM. Then plug in and try turning on again.
3. If it doesn't work, then unplug again, and locate the CMOS battery* in your laptop. Unplug the CMOS battery carefully and wait for 2 minutes before plugging it back in. Then plug power and try turning it on.
***My CMOS was right next to my harddrive and looks like a black round button that was wrapping in black tape. It had "KTS XXXXX 3.0V" written on it. The 3.0V helps you verify that this is the CMOS battery.
Step 3 worked for me, so if you are running into the same issue, I hope this method can help you too!

Thank you, this worked for me, too [Asus X554L]. But more importantly: what causes this to happen and how to prevent it? I've had this happen to me 3x during the past week. I even paid to have it serviced, but I guess that was a terrible mistake since the hard reboot did exactly the same job...

Thank you a lot!! Just started college yesterday and it stopped working, fixed it with the Hard reset.
