BIOS file attached as RAR file.

After reading some forums I have extracted the .fd & .rom file and copied into USB 2.0 drive and tried to recover BIOS but BIOS recovery process never initialized. It seems the .fd or .rom file must be renamed into BIOS specific name but I have no idea what that file name supposed to be. I believe you can figure that out as well.

I used the above method and the link shared for dv5. Tried renaming the 3603f21.fd file to 3603.bin, 3603.rom, just 3603.fd after opening the platform.ini file from original bios.exe. However, there was no beeps, but CAPS/NUM SCROLL LOCK flashed continuously. No bios recovery screen appeared, no self shutdown in the end either. I waited like hours, couple of times. No luck so far. Really need this Laptop working again please help!
Thanks!

Hi!
You need to leave the name "3603.bin". Since there is no reaction to holding the key combination, then do not expect it. In general, if the caps lock starts flashing, then the recovery has already failed. Actually, you just need to hold the power button for 3 seconds maximum, but Win + B must be held until the USB reading is initialized.
