have bios for np540u3c-A03UB lotus13-tsp / rev. 1.0 With the original bios it hangs on the samsung logo, I recorded it with 2 of here and it does not present video - I left more than 1 minute on and nothing
I try other bios for this laptop model, and screen apears with Samsung logo, and goes off and on ,in a loop, but with that bios you linked screen is always off.
