DV5-1157ca won't boot after flashing bios [ Edited ]

[zijin_cheng]

I have a Dv5-1157ca with F.0B as bios. I download F.21 and tried flashing the bios. I hit start and it started then i went to bed, when i woke up the screen was blank but the quickplay buttons were still lit up.

I called customer service and they told me to remove the CMOS battery for 5 minutes

I tried removing the CMOS battery for 1/2 hour with A/C and battery out but the lappy still won't start.

What do i do?
