Bought this computer usedThe guy bought an extended batteryhe upgraded the Bios from A04 to A07The battery would no longer charge.
Web research showed that some after market batteries only worked with A00 or a04 bios installed.
To downgrade the bios.Downloaded the A00 bios from DellPut the file in the c: root directory.run the program.
It would not downgrade the file.
Need to go in the c:\windows\temp\bios folder run the bio utilityselect advanced setting.unclick the check for newer version bios option.
Then the run the bios update.
sorry for restarting old thread but this is relevant. I have inspiron n5010 and updated bios to A15 fan dosent ever shut off now. extremely annoying and kills battery. I don't have a floppy on a laptop, and don't understand your directions about root directory. when I try to run a12 just the regular program downloaded from dell, it says warning we don't recommend to downgrade click ok to exit blah blah blah. I want to downgrade so that my laptop runs normal again. so I have the application file from dell, now what do I do. what is root directory? how and where do I find the bio utility to run advanced settings? I looked in temp and found nothing of the sorts. if you could help that would be great. I hate this OS only bios updating program and really am getting annoyed at how dell lets bad bios's get through the cracks.
