Update: I just tried turning on the laptop again after changing NOTHING and it's working perfectly fine as if nothing happened now... I honestly don't know what to say, but thanks for the help anyway!

I just tried turning on the board with nothing but the power button, power plug, USB keyboard, and external display connected to HDMI and the same thing is happening. It seems like the USB keyboard isn't even getting power (it has LED lights on it). Does this mean the board is completely fried? How should I go about testing the board? Sorry, I've never repaired electronics like this before, should I just bring it to a repair shop?

I will try this when I get the chance, thanks!

Thanks for the reply! Caps lock does not respond at all. The ram is also soldered onto the motherboard.

Hey everyone, a couple of weeks ago my Asus G14 GA402XV-G14.R94060 froze completely (the first time this happened), so I had to force shutdown. Ever since that, it has never booted again. Pressing the power button makes the power led to go on (drive led never blinks) and the keyboard also lights up. If the board gets hot enough, the fans will spin. Sometimes, if I'm not plugged into power, pressing the power button won't do anything at all. After a couple of seconds though, it just turns off. I tried unplugging the battery and holding the power button for 60 seconds, which supposedly resets CMOS,...

Hey everyone! Just trying to fix my laptop... but I'm a university student studying computer engineering.
