I know other people tend to ask, how to update bios on Dell Latitude C600/C500 without battery checking, or force to update bios on Dell latitude C600/C500 without battery support only AC power.

Well, there is a solution but you’re putting a large risk on your Laptop.

Note : Check your BIOS, if it’s A21 your probably need a BIOS Update A23. You can see it at Dell welcome screen,below the Logo or Press F2 and check on the BIOS. Be warned, wrong BIOS may damage your BIOS and maybe worst, your system will not function. (I am not responsible for any loses). And one more thing, flash your BIOS with AC Power correctly plug to your AC outlet, again I am not held responsible for whatever happens onwards, and when everything goes wrong.)

BOOT ON CD-ROM Drive (Be sure you’re CD-ROM Drive is working properly, or else it will fail or even worse, again I am not responsible for it)

1. If you have a CD Burner, Download this CD Bootable Image file(ISO). It’s in zip file, so extract it and burn the ISO from the CD-R or CD-RW. (It’s up to you)

2. Press F2, Go to Boot Priority, then set on the First Boot on the CD-ROM Drive. Put the CD into the CD-ROM Drive, and reboot.

Warning: Flash a BIOS without Battery Support, I am not held responsible for whatever happens onwards, and when everything goes wrong.

3. Using for Bootable CD Flash BIOS on Dell Latitude C600/C500, after the boot, I know it will not continue to update press ESC, then you will be at D:\> (My CD-ROM Drive).
From there, type the upgrade file .EXE, say for example: D:\>C600_A23.EXE /forceit /nvram
D:\> C600_A23.EXE /forceit /nvram

/forceit – force BIOS to flash without battery installed.
/nvram – Dell splash screen will be keep.

The reason why Dell doesn’t want you to be updated without battery installed, if you’re AC power failed, the battery installed will support your power and flash bios update still continue. Or else the laptop will not work properly.
