I have an Asus laptop A455L. It won't turn on, when I press the power button the indication lamp is not lighted and the screen is black, I though my laptop is out of battery so I charge my laptop, the charged indication lamp is turning on, and I press the power button again and the power indication (like a "lamp") is turning on with a steady white, my laptop is still black screen and I hear a small steady noise (iiinnnggg....).

Could you help me please..
 
Hi,

Please do try these troubleshooting steps that I suggested to others who had the same problem that may help.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work 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.
