@akcent You just do a Module method mod & correct the RSDT & XSDT table names. The mod isn't permanent but can be flashed via Asus WinFlash. You made a permanent mod by adding SLIC in DMI area for me, it was flashed from DOS using AFUDOS. I have the same laptop - Asus X53SC, Indian variant of K53SC.
I get the error "Unknown Result!" using yours. Are you saying to use the windows flash tool versus the Dos one?
