    Hi all,

    Please help me on updating bios for Inspiron 1525. Since inspiron battery is dead, no longer charging, i cannot update modded bios with just a charger. Every time i do an update, error pop up saying battery need to be 10% or higher to update bios. This is a window bios update. Is there anyway to update bios without battery installed? if so, please guide me.

    Thanks

    Worked for me! Thanks very much. (April 2013)

    I was lucky enough to have a floppy drive that I could attach using USB and the A04 BIOS of my B120 accepted it as a boot device.

    So, I simply formatted a 1.44 MB diskette (Remember what those are? LOL) and selected the option to create a bootable DOS diskette.

    When that was concluded, I copied M051A08.EXE onto the floppy and restarted the computer.

    The switches "/forceit" and "/nvram" were accepted and my BIOS update was accomplished without a hitch.

    Computer actually belongs to someone else and I was happy to not have to sell the idea of a new battery for such an old computer. Now the BIOS is up to date; Dell is very unlikely to add any newer versions. A few more files to add and a complete virus scan and I'll be ready to return the beast to its owner.

    For a seven year old computer with only a Celeron and only 512 GB RAM ---- well, I wouldn't trade mine for this one, but it isn't bad.

    Thanks again for the very fine tip about the forcing switches.
