OK that was very helpful, thank you.
First, you are not really in BIOS mode, it just won't boot.
Couple that with the fact that your screen is trashed, and the reason the computer is beeping could be
when the screen got broke, so did the Backlights, which damaged the motherboard Power Supply. And before I go any further, I am forced to ask.......
Do you REALLY want to try to fix a computer that has a smashed screen, and an almost certainly **cked-up
motherboard......... do you REALLY want to tear it apart to purchase and replace replace the screen, which HAS to be done before you
try to find out if the motherboard is even worth repairing or replacing?
Smashed Screen+ possible damaged backlights + Dead MotherBoard = pull the hard drive for it's data, and get a new computer.
Dude, I can FIX ANYTHING! But all too often the question is, "Is it worth it?". In my opinion, Here the answer is a Big Fat NO!!!
