I recently Replaced the screen on my 4530s, and followed a guide to replace the screen correctly, was careful to not pinch any cables, and kept all electronics free of static. however, when I boot up the computer, the LCD screen turns on, but the BIOS doesn't display. keep in mind that the computer currently does not possess a hard drive, but before I replaced the screen, I made sure that the BIOS loaded on the cracked screen.do I simply have a damaged/crushed cable, or is there something I'm not noticing when I installl the screen? I've disconnected and reconnected the cable from the screen itself multiple times, and still have the same problem; I've even booted the computer without the bezel on to make sure it wasn't squashing any cables, but the problem persists.
