If the external monitor works fine and load the operation system, most likely you have a faulty screen or bad video cable connection. Check them and replace the faulty one.

BIOS failed; Laptop Asus G752VL won’t turn on at all, if the voltage 19V, 3.3V, 5V OK  and electronics components on the motherboard are good, there is chance you have failed BIOS. There is a signal test confirmation on EC/SIO pin name RSMRST# . This pin must available 3.3V(tolerance 10%) than Bios Confirmed OK. If the test failed reprogram or replace the BIOS chip.

Laptop Power System has problem: Laptop Asus G752VL won’t turn on at all, probably some electronics components or chipset on the motherboard failed;  Disassemble the laptop and take out the motherboard. Ceck No burnt marks visible on the mainboard. Check chepset temperature (CPU,  GPU, Power-Supply IC …). Check power jack. Check motherboard receives 19V. with a Multimeter measure voltages on coils, check for any components shorted to ground.  checked 3.3v/5v is up and running?

If you  have 3VALW And 5VALW at coil. 3VALW should go to sio and from there you should get 3v at power button. Check SIO for corrosion,shorting or any componenets which looks suspect. Check 3 & 5v SUS voltage.

    I recieved this laptop and it wasnt showing any signs of life…i removed everything and left only motherboard on the table..it came with 2 sticks od 8gb 2133 ddr4 ram. I tried one stick of ram at a time, then i get the fans running at max…so i reprogrammed the bios. After reprogramming i have picture, sound…everything, it goes in to the bios, and when hdd is in it boots into the windows, and i can work…. or so i thought….
    The problem is when i try to assemble it and put another stick of ram, it would not post picture, or show anything on the screen…i was thinking maybe a bad ram, but i used that ram on other laptop and that laptop booted normally. I even put some other 4gb ddr4 ram i have (and it works on other laptops) but its the same…it will not boot to bios or windows. When removed and left only one (first) it works….BUT..then i tried to put that working ram in other slots and no, it will not boot, i put it back where it was in the first place and it works! WTF?
    Then i flashed it from 219 to 304 but again the same thing!
    One more thing, when putting another ram i can see backlit keyboard, and fans spinning and one interesting thing is the led that indicates charging battery is green blikning?! (when laptop works without that one working ram its red/orange not blinking)
    Anybody any idea? its driving me crazy thank you!
