Stuff I tried:
Hooked up another monitor, nothing there.
Retried the previous Hard Drive, no luck.
Disassembled and cleaned it altogether, still nothing.
The laptop powers on, no doubt. What I discovered, is that the HDD Led isnt blinking. So this might be Hard Drive related.
I dont have much idea about booting up, but isnt it on the motherboard? Does replacing the Hard Drive affect it?
Laptop: Asus X54C, Intel Pentium B970.
