Re: Asus x455lf problem
try to monitor the voltage of the bios ic..it must maintain proper vcc voltage and also the rtc battery if any.. check the core voltage.. 1.2 or 1volts.. also the always on voltages.. if all voltages are correct. try to use an external monitor..sometimes there is no indication the laptop is working but when you place external monitor you can see its working perfectly i experienced that with lenovo laptop bad lcd screen with busted led front display..Never stop LEARNING because life never stops TEACHING!

@duranitron thanks for the response, I check the voltage on bios ic pin 8 once it start turn on white light and goes off to orange then suddenly turns to white light and goes back, Ive noticed that pin 8 on bios ic goes fluctuating voltage it goes from 3.3v to 1.8 and goes back to 3.3 and drops off to 1v, also i noticed the vcore voltage 1.0v is fluctuating also from 1v drops to 0v and goes back.
