    Laptops have eeproms, electronically erasable programmable read only memory. Removing the CMOS battery doesn't reset them like a regular eprom in a desktop PC. All it does is mess up the date and time, all the other settings like passwords etc stay in-tack. You have nothing to loose by trying it but I don't think it will help. If you are not getting any kind of BIOS message on the monitor it is probably bricked. If you poke around on the manufacturers web site you might get lucky and find a BIOS recovery procedure. It usually involves pressing a certain key combination while powering up the laptop with a bios file on a thumbdrive or floppy. disk. You may have to really hunt to find and there is no grantee it will work.

    Nice post alpha, I have never managed to find one of these, and as you say, there is a pre-requisite for the hardware to support it.

    LAPTOP BOARD MAKERS TAKE NOTE: MAKE THIS A STANDARD FEATURE!

    My two ASUS motherboards have a CrashFree BIOS utility built into them. They will auto recover/restore the BIOS file if it fails or gets corrupted during an update process. I can restore a corrupted BIOS file using the motherboard support DVD or a removable device that contains the updated BIOS file. The instructions are all listed in the manual. Any decent motherboard bought today "should" have Boot Block, or Dual BIOS etc and some type of recovery option. Flashing your BIOS on todays hardware is not as dangerous as it used to be.
