The keyboard backlight was now fully functional, and the FN + F3/F4 keys were now functioning fine.Īfter reading the tutorial on how to flash your bios using easyflash you can proceed to download the file below. I then proceeded to use the Asus EasyFlash that is intregrated into the BIOS Setup, to flash with the newly created ROM.Īfter the flash was complete, I restarted the laptop.

I used the AMI AFUDOS tool from DOS with option /x (to surpass compatibility checking) to flash the BIOS, using command: AFUDOS G74SX.ROM /x The BIOS was at the latest version, 203, so flashing under Windows wasn’t an option, as this would produce an error. I started at point 1, and immediately began to flash the BIOS.

This wasn’t happening on this particular machine. On a working G74SX during POST, the keyboard backlight flashes on then off. I also tested a known working keyboard, which produced the same result. I stripped the machine down, and reconnected the backlight cable, after cleaning the contacts with IPA. I noticed that the backlit keyboard wasn’t illuminating / working at all. 3) Right-click the device drivers that you want to update and click Update driver.Whilst looking at a number of different Asus G74SX gaming laptops, a common issue became very apparent. 2) Expand the category of the drivers that you want to update.
