I suggest you to download Latest BIOS software to a bootable USB device. Firstly Connect the USB device after restarting the computer while tapping F12 key. This gives you boot options from which you need to select USB device. You should see the BIOS software which has already been copied to the USB driver. Select the file and start the application. Ii recommend you to connect the AC adaptor while flashing BIOS. Restart your once this process is complete.
Follow the steps mentioned below:
1.Download the file: T3600A04.exe (5MB) to USB drive
2.Boot from the USB to the DOS prompt.
3. Run the file by typing T3600A04.exe (where y is the drive letter where the executable is located).
Please revert for any further queries and I would be glad to help you further
I apologize for the wrong information given in the previous post. I would like to inform you that we will be able to do the BIOS update only in the operating system. It wont work without or outside the operating system.
Like most of my interaction with Dell, this is just plain the wrong answer and demonstrates a basic lack of technical understanding, general apathy toward the needs of their customers, and a lack of comprehension of the English language. I found this when having the same issue using the window 7 recovery disk. I had downgraded my bios trying to get a piece of hardware working without realizing the older bios doesn't support my onboard drive controller. Whoops. I think this error is caused because the recovery disk is designed for the 64-bit version of windows. Here's how I got around it: Download Rufus Format your USB drive as "free dos" bootable Copy the driver package to the USB drive Reboot and press f12 to select USB Then run c:\t3600a09.exe and follow the text prompts The system will automatically reboot and apply the patch after POST
I did all you suggested but when I get to run the bios.exe program it says that the programm cannot be run in DOS mode. Not sure you can use this process for the latest dell bios executables?
As informed by DELL-Harish R you will never be able to flash BIOS in DOS prompt or outside the Operating system. The system should boot to the desktop to perform this step.
I have almost the same issue i have to update my BIOS on my Inspiron 3721 to the latest BIOS available, but i am not running windows (but the latest ubuntu) on this machine.
I did follow the standard procedure to create a DOS usb stick, i copied and tun the .exe in it, and it return Test then nothing I am in deep trouble i have the fan issue and i have 10 laptop to install for my company.
Here is the bios :
Dell Inspiron 3721 System BIOS - AO09. I have also try previous BIOS.

I have a bootable FreeDOS USB flash drive. So I would copy O7010A29.exe to it and run it.
