Bought this computer used
The guy bought an extended battery
he upgraded the Bios from A04 to A07
The battery would no longer charge.
Web research showed that some after market batteries only worked with A00 or a04
To downgrade the bios.
Downloaded the A00 bios from Dell
Put 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 utility
select 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.
I have a similar issue with an Inspiron 14z bios A13 where fan and power light stays on after the computer shuts down or goes to sleep. Is this what you are experiencing?
