Warning: Inspiron 7520 - BIOS version A07 is non-downgradable

Before you decide to flash your Inspiron 7520 to BIOS version A07 and above, please do note that you cannot downgrade to A04 or A02.

Currently I have BIOS version A07 on my laptop PC. I was unable to flash it down to A04. The update operation just terminated abruptly with a reboot.

Hi tearlach2,

Please find the link below to flash BIOS to version A07 for Inspiron 17R SE.

Click on ‘Download File’ to flash BIOS to the latest version that is A07. Please connect the ac adapter as this step needs uninterrupted power supply. Do not use the system till it restarts and comes up to the desktop.

The update contains feature enhancements or changes that will help keep your system software current and compatible with other system modules (firmware, BIOS, drivers and software).

Thanks and Regards,

Hi I have just recieved the 15R SE today, according to my dell app I have the A05 BIOS, where do I get the A07 BIOS and what are the fixes/enhancements?  It doesn't show any BIOS download for me based on my Service Tag.  I have the i7 with 750GB HD model service tag is <ADMIN NOTE: Service tag removed per privacy policy>.

Are you sure that your machine is 15R SE a.k.a. Inspiron 7520?

To the best of my knowledge, the BIOS versions for it are A02, A04, A06 and the most current being A07.

The link to the download page for A07 is http://www.dell.com/support/drivers/us/en/19/DriverDetails/Product/inspiron-15r-se-7520?driverId=3H6TW&osCode=W764&fileId=3080091954

Unfortunately Dell doesn't give details about what A07 does, fixes or enhances. You may have to email Dell tech support for that.
