Absolutely. Let me tell you the story. A HP 430 laptop was given to all of us students from our college. Now everyone was facing a BIOS problem which perhaps happened due to a BIOS bug and it fixed in a later revision. All the laptops which were under warranty had their motherboard replaced. Now a student gave me his laptop with BIOS problem(warranty over now). I opened it up cleared the CMOS and it worked. So I updated the BIOS. Completed successfully and rebooted. Now when I turned off the power and power on again, it will not boot and the caps lock will blink 2 times(BIOS corruption). Resetting the CMOS no longer works. Please note my laptop(same model) runs the same BIOS(latest) that I updated his with. I made a recovery HP tools disk with the BIOS files. The screen comes and writes BIOS but the verification fails at block 607/1056. I checked the log file and it says device error. So this is the story. To verify if I was following the correct recovery method, I deliberately destroyed the BIOS of my laptop(removed power while reflashing) and then recovered it. It passed in one shot. So it must be the BIOS chip that is faulty.
