I had an issue with A09 where it would make my graphics card not work. I forced A04 using the end key and flash drive method, then I tried to do the same with A09 but it was taking much longer than A04 did, it beeped for a few minutes, then it beeped faster for a while, and then it stopped beeping but did not shut down and restart. After a while I unplugged the power. Now I have nothing at all. No lights, no power, no fans, nothing at all. I have removed the CMOS battery and power cycled it. No response from the computer, not even a beep. I am out of warranty as well since this is a replacement and need to find a way to fix the bios.
