I would first like to warn you that any BIOS update has the chance to brick a computer.
I would look in BIOS to see if there is any setting that keeps it from being written to.
I found this on Dells site for your computer.
1. Please note that if the A01 BIOS is currently installed on your system you must first apply the P02 patch (E6410P02.EXE) before upgrading to this BIOS.
2. Please note that if the A08 or before A08 BIOS is currently installed on your system you must first update to A09 BIOS and then flash to the latest A-rev BIOS.
3. Please note that if the A10 or before A10 BIOS is currently installed on your system you must first update to A11 BIOS and then flash to the latest A-rev BIOS.
Flash to A09 using dls62's link before you can flash to A16.
Download Rufus. This will create a bootable USB flash drive with FreeDos.
Make sure it is your USB flash drive listed as you do not want to format your hard drive. When you run Rufus, you can select FreeDos in the dropdown box under "Create a Bootable disk using an iso". Make sure Quick Format is selected with FAT32 as the file system and a MBR partition scheme. Any data on the USB flash drive will be erased.
Boot the USB flash drive using the F12 boot menu to see if it correctly boots. If it does proceed to the next step.
Download your correct BIOS file for your model. I am using the name E6410A09.EXE for example purposes.
Copy E6410A09.EXE to the root directory of your USB flash drive.
First, make sure your battery is fully charged and plugged into the A/C adapter.
Attach the USB drive with the E6410A09.EXE file and boot the computer.
At the FreeDos prompt which should be A:\ type C: and then dir to see if you can see a list of files on your USB flash drive. If not try another letter until you can get a list of files with the DIR command.
When you have the correct Drive letter listed type:
Do not interrupt the power or touch the power button. After the BIOS update you may have to reset BIOS setting to default.
