Hey, greetings all. I'm having issues reflashing my bios. i'm following procedures to recover my bios as someone changed settings in the bios and now when my laptop starts, i get the keyboard light and a black screen. i've tried flashing via usb with the file name DH53FX64.fd, as well as putting it on my flash drive formatted in fat32 with that being the only file in it, and holding fn+ESC following by plugging it in and pressing the power button, but the fans just spinning on high (i'm guessing that it does go into the bios flash menu but i dunno) and it doesn't power off for itself, nor does the flash drive light up (ive tried all three ports). I've waited 20mins in between and I keep trying. Can anyone assist?
