I have a Dell Inspiron 15R 5521. Since a while now my laptop is given me messages explaining my battery has a fatal error and needs to be replaced. I have been searching for a different solution than simply replacing the battery/adapter and I've seen that a lot of people had to update their BIOS. I currently have BIOS A07. When I try to update using the driver I've gotten from your site this window pops up and tells me I have to plug in my battery and adapter. Both are plugged in but I can't seem to manage to start the update.
I hope you guys can help me,

Hi Dries Vanden Broecke,
Download the A14 BIOS here - http://dell.to/2diZOfL
Now, for the BIOS update to run, it is required that the battery be connected and battery should contain a minimum charge of 10% and the adapter needs to be detected in BIOS.
Having said this, Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point. Check the battery health in BIOS (if applicable).
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.
