are you sure you updated the bios with the right one that corresponds to your machine ? always make sure before updating the bios that you have the right bios version otherwise you take the risk of having issues after that.
UPDATE: Okay, today my laptop exhibited behavior I haven't noticed before. I've press the eject button on the laptop's button several times and it proved to be working every time it boots up, but I've noticed that the fan now periodically turns on and off because of this. It may be looking for a 'recovery disk' through the CD drive, but I haven't looked around the internet much to confirm. Will try to flash recovery my bios through the CD drive to see if it would work or not. UPDATE 2: I left the laptop off for a whole week before deciding to try and boot it up again. Guess what? It somehow managed to miraculously bring itself out of its own hell.
