Inspiron 6400 Bios Update
Like many other peoples Inspiron's mine does not charge the battery anymore.
Is there away to run the bios update bypassing the low battery charge that comes up?
Any help would be fantastic.
Thanks
Garry

From a dos environment there is a command line switch.
THIS CANNOT BE DONE IN A DOS WINDOW. IT MUST BE PLAIN MSDOS WITH NO MEMORY MANAGER.
Bay Wolf's Inspiron & Latitude BIOS FAQ
This is not recommended if you dont know what you are doing.
If you chose the wrong bios this will permanently kill your laptop.
When you flash your BIOS without a battery, you do so at your OWN risk.
I am not responsible for your decisions. Should something go wrong with the BIOS flash, you may end up with a computer that will not operate.
A: Use the floppy disk version of the BIOS upgrade. Create the Bootable BIOS floppy disk with the program that you just downloaded from Dell's Download Site.
Boot with the BIOS floppy disk in the A:\ drive.
One way to do this is with the computer off, put the floppy disk in that you just created in the
A:\ drive and then turn the computer on. The BIOS update will fail because you do not have a battery in. Then at the A:\ prompt (you are now in DOS),
type in the BIOS upgrade EXE file name and just add the switchs /forceit and /nvram. The /forceit switch will force the BIOS to flash even when the battery is not present. The /nvram switch will make sure that you keep the Dell Splash Screen.
For example, for the Inspiron 8000, the command would be A:\I8000A22.EXE /forceit /nvram.
Note, there is a space between the E and the /. There is also a space between the t and the /.
But be forewarned - the reason that the BIOS update wants a battery is to prevent a flash failure due to a power interrupt.
