I flashed my netbook, and then rebooted, but now it`s LEDs on the down blink and screen is black

I did some research on your Netbook…Sometimes the manual has the procedure on how to reset the BIOS after a failed attempt " I don’t see it". What your gonna have to do, is contact ASUS Support and find out if there is a way to recover it. It may involve taking the Netbook apart and setting some jumpers, or they may have media that will get your BIOS back. I am not going to say that your Motherboard is bricked, because newer Motherboards in SOME cases..The BIOS is recoverable. ASUS Support Number: 1-888-678-3688
