G73sw blank no bios logo
Few days ago my laptop suddenly shut off, when I turned it back, it just goes blank, no bios logo. I already tried some solution like removing any hard drive, removing/switching ram, removing battery, connecting external monitor, holding power button for 30s/1m and so on, etc. But still no luck. I'm not sure what's the problem. Is it cause of a dead gpu?
I tried turning on while plugging my external rgb keyboard/mouse, and they didn't lights up. Does dead gpu also causing that? Or it could be something else? Thanks before
